Additional Products

There are additional products you can use with your Lift:

• Aligner. An Aligner is a hardware/software product that lets you perform wheel alignments. If you
already have an Alignment Lift, like the HDS-18EA, simply purchase the Aligner and you can start
performing wheel alignments.

Refer to the Aligner page on the BendPak website for more information.

• Rolling Bridge Jack. A Rolling Bridge Jack raises the wheels of a Vehicle off the Runways of a
Lift, like an HDS-18EA, making it much easier to perform service such as brake jobs and
suspension work while the Vehicle is still on the Lift.

You can raise two wheels off the Runways if you have one Rolling Bridge Jack. It takes two Rolling
Bridge Jacks to raise all four wheels off the Runways.

Refer to the Rolling Bridge Jack page on the BendPak website for more information.

• WSA-100 Air/Electric Workstation. The Air/Electric Workstation adds air and electric
capabilities to your Lift. It includes four electrical outlets and specialized air service outlets, among
other features. Refer to the WSA-100 Air/Electric Workstation page on the BendPak

website for more information.

can tell the Power Post from the other Posts because it has two Mounting Brackets on it.

• The other three Posts. These Posts are interchangeable, although their Labels are different.

• Power Unit. An electric/hydraulic unit that connects to an electric power source and then
provides Hydraulic Fluid to the Hydraulic Cylinder that raises and lowers the Runways.

• Powerside Runway. The Runway on the same side as the Power Post. The Powerside Runway
has the Hydraulic Cylinder and the Cables under it.

• Offside Runway. The other Runway. It does

the Lift.

• Crosstubes. One at the Front of the Lift, one at the Rear. The Crosstubes are hollow; the Cables
that raise and lower the Runways are routed through the Crosstubes. The Crosstubes are not
interchangeable: the Front Crosstube has a small opening (called a ‘Window’) that faces the inside,
the Rear Crosstube has a larger Window that also faces the inside of the Lift.

the inside of the Lift only

• Ramps. One for each Runway. Use them to drive onto and off of the Runways.

• Tire Stops. Located at the Front of the Lift, Tire Stops prevent the Vehicle’s front tires from going
any further forward. Additionally, we strongly recommend chocking the Vehicle’s rear tires.

• Turn Plates. Movable plates that go near the Front of each Runway; required for alignments.
You must orient both Runways so that their Turn Plates are at the Front of the Lift, whether you are
doing alignments or not.

• Filler Plates. Two per Runway, they sit on either side of the Turn Plate. Gives you the ability to
align Vehicles with a wide variety of wheel sizes.

• Slip Plate. A large movable plate on both Runways towards the Rear of the Lift; used for
alignments.

• Safety Locks. Once engaged, they hold the Runways in position, even if the power goes out or
there is a leak in the Hydraulic Hoses. Your Lift has 13 Safety Locks, spaced every four inches (100
mm). This lets you lock the Lift at just the right height for what you want to do. The Lift also has a
backup Slack Safety system; refer to About Safety Locks for more information.

your Lift fully lowered or engaged on a Safety Lock.

• Pushbutton Air Valve. Holds the pushbutton that moves the Safety Locks away from the
Ladder so that they do not engage as you lower the Runways.

• Ladder. A piece of steel that is installed at the back of each Post. Each Ladder has 13 holes in it,
which are part of the Safety Lock system.

• Aligner. An optional, separate product that lets you perform Vehicle alignments. Refer to the

aligner page on the BendPak website for more information.

• Rolling Bridge Jacks. An optional, separate product that raises wheels of the Vehicle on the
Lift off the Runway, making it easier to perform brake jobs and suspension work while the Vehicle
is still on the Lift. Refer to the Rolling Bridge Jack page on the BendPak website for
more information.

Frequently Asked Questions

Question: What kinds of Vehicles can I put on my Lift?

Answer: Cars, trucks, SUVs; anything that fits on the Runways, up to 18,000 lbs (8,165 kg).

Q: What is an ‘alignment’ Lift?

A: A Lift with special components that allow it to be used to perform automotive alignments. The

HDS-18EA is an Alignment Lift. An alignment is an adjusting of the angles of a Vehicle’s wheels to
the manufacturer’s specifications, which generally reduces tire wear and makes the Vehicle drive
without pulling to one side. The HDS-18EA can also be used as a Service Lift or a Parking Lift. A
Service Lift gives access to the underside of a Vehicle for maintenance tasks. A Parking Lift lets
you park one Vehicle on the Runways and a second Vehicle under the Runways.

Q: How long does it take to raise or lower the Runways?

A: About 75 seconds.

Q: Does the Lift have to be anchored in place?

A: If you are using it as an Alignment Lift, then yes, you must anchor it. If not, then it is up to you. A

four-post Lift is pretty stable, but for safety reasons we recommend anchoring it.

Q: How high does the ceiling have to be?

A: It depends on the height of the Vehicles you are putting on the Runways and how high you raise

the Runways. If you are going to put a tall Vehicle on the Runways and raise it all the way up, you
should measure, in advance, to make sure there is enough room.

Q: Does it matter if I drive my Vehicles in front first or back them in?

A: We recommend driving your Vehicle in front first, because that makes it easier to center the

Vehicle’s wheels on the Runways. Nevertheless, you are not required to drive them in front first.
Whichever way you drive the Vehicle in, remember to put the wheels at the Front of the Lift up
against the Tire Stops and chock the wheels at the Rear.

Q: Will the Cables really hold my Vehicles?

A: Yes. Your Lift has .63 inch (16 mm) thick, aircraft-quality Cables (technically wire rope) that runs

through oversized sheaves, reducing friction on them and extending their life with minimal
maintenance.

Q: How long can I leave a Vehicle on a raised Runway?

A: As long as you want. Once the Lift is engaged on its Safety Locks, gravity holds it in position, so a

loss of power does not make it come down; it is going to stay where you left it. You should always
leave your Lift either fully lowered or engaged on its Safety Locks.

Q: Can I install my Lift outside?

A: Your Lift is approved for indoor installation and use only.

Q: How many Safety Lock positions does my Lift have?

A: 13, spaced every 4 inches / 100 mm.

Outdoor installation is prohibited

The Lift supports less weight than its rated capacity when the Vehicle’s wheelbase is shorter; this is
because the wheels of such a Vehicle are closer to the middle of the Runways, where there is less
strength. For example, the maximum weight allowed on the Lift for a Vehicle with a wheelbase of
135" is 50 percent of the Lift’s rated capacity (9,000 lbs when the rated capacity is 18,000 lbs).

Unloading and Unpacking

Try to have the components of the Lift unloaded near the installation location.

Once the components are unloaded, they are your responsibility to move around. As the Lift includes a
number of heavy pieces, the closer you unload them to the installation location, the better off you are.

⚠ CAUTION Some Lift components are very heavy; if handled incorrectly, they can damage

materials like tile, sandstone, and brick. Try to handle the Lift components just
twice: once when delivered and once when moved into position. You must have a
Forklift or Shop Crane to move them into position. Use care when moving them.

⚠ WARNING The Posts and Runways are delivered with stabilizing structures on each end. Be

very careful when removing these stabilizing structures; the Posts and Runways

Installing the Crosstubes

Your Lift has two Crosstubes:

• Front Crosstube: Has the Small Window, where two Cable Sheaves go. Located at the Front of
the Lift, with the Window facing the inside.

• Rear Crosstube: Has the Large Window, where four Cable Sheaves go. Located at the Rear of
the Lift, with the Window facing the inside.

Both Crosstubes are hollow, which allows the Cables to be run through them to the Posts.

The following drawing shows both Crosstubes and additional components.

Drawing not necessarily to scale. Some components not shown.

Crosstubes have a Crosstube Gusset on both ends, for a total of four Crosstube Gussets per Lift.

About Safety Locks

Safety Locks hold the Runways in place. Once engaged, Safety Locks hold the Runways in place even
if the power goes out or the Hydraulic Hoses break or leak. Your Lift has 13 Safety Lock positions,
spaced every four inches / 100 mm. Each Post has its own Ladder and set of Safety Locks.

Important: Simply raising the Runways does not necessarily

You must back the Runways down onto the Safety Locks to engage them.

engage

them on the Safety Locks.

⚠ WARNING Safety Locks are dependent on correct installation of the Ladders. Pay careful

attention when installing the Ladders.

The Ladders, one per Post, are steel pieces with 13 holes spaced every four inches / 100 mm. As you
raise the Runways, the Safety Locks move into the holes in the Ladder; these are the sounds you hear
when the Runways are moving. When you move the Runways back down a little after passing a Safety
Lock, the Safety Locks engage. Once they are engaged, Safety Locks stay engaged until you are
ready to lower the Runways. Even if the power goes out or one of the Hydraulic Hoses breaks or leaks,
the engaged Safety Locks hold the Runways in place.

⚠ WARNING Always leave the Runways either fully lowered or engaged on their Safety Locks.

When you engage the Safety Locks at a desired height, check to make sure that all
four Safety Locks (one per Post) are engaged.

How do the Runways come down if you have engaged the Safety Locks? To lower the Runways, you
raise them a few inches (to get them off the Safety Locks), then
on the Pushbutton Air Valve. While you hold down the pushbutton, the Safety Locks are moved away
from the Ladders; in this position, they cannot engage, which allows the Runways to be lowered.

Out of an abundance of caution, your Lift has a second, independent Safety Lock system called the
Slack Safeties.

the pushbutton

The Slack Safeties are physically located next to the Safety Locks on the ends of the Crosstube
Gussets. They are different from the Safety Locks in that when the Cables are taut (which they are
during normal operation), they hold the Slack Safeties away from the Ladder so that the Slack Safeties
cannot engage. However, if a Cable were to break (which very rarely happens), the Slack Safety for the
broken Cable immediately engages, preventing the Runways from falling.

HDS-18EA Alignment Lift 19 P/N 5900970 — Rev. C2 — March 2020

Installing the Ladders and Top Cap

Your Lift has four Ladders (one per Post); each gets installed on the inside back of a Post. Ladders are
secured at the top and the bottom.

The Top Caps secure the Ladder at the top of each Post and hold the ends of the Cables.

Note: It is much easier to secure the bottom of the Ladders once the Crosstubes have been

raised, so that portion of installing the Ladders is described in Securing the Ladders.

Each Ladder has 13 holes in it, spaced four inches / 100 mm apart; these holes are the Safety Locks.
Each Ladder has a Bolt Hole at the bottom and a Threaded Bolt at the top.

⚠ WARNING Make sure to install the Ladders correctly. If they are not installed correctly, the

Safety Locks on your Lift may not hold the weight of a Vehicle, putting anyone
under the Lift in danger.

HDS-18EA Alignment Lift 20 P/N 5900970 — Rev. C2 — March 2020

To install the Ladders and the Top Cap:

1. Take a Ladder and slide it down the back of the Post, Bolt Hole end at the bottom; see the
drawing on the previous page.

Make sure the Ladder goes through both Slots on each Gusset

⚠ WARNING Make sure the Ladders go through both Slots on their Gussets. If the Ladders are

not installed correctly, the Safety Locks on your Lift may not hold the weight of a
vehicle. If the Vehicle were to fall, it could cause significant injury to anyone
underneath it.

2. Install the other three Ladders the same way.

3. For each Ladder, put a Stop Nut on the Threaded Bolt at the top; move it half of the way down
towards the top of the Ladder.

4. Put a Top Cap onto the top of the Post, securing it on the sides with one Hex Head Bolt and one
Nyloc Nut on each side of the Top Cap.

5. Once the Top Cap is secure, move the Stop Nut up until it contacts the underside of the Top Cap,
then add a Flat Washer and Nyloc Nut to the top of the Top Cap and tighten it. Only hand tighten
at this point.

You are looking for about an inch of thread above the top of the Top Nut.

Note: The other hole in the Top Cap is for the Cable that is routed to the top of the Post, which

is done later in the installation.

6. Install the other three Top Caps the same way.

HDS-18EA Alignment Lift 21 P/N 5900970 — Rev. C2 — March 2020

Raising the Crosstubes

You need to manually raise both Crosstubes, which makes it easier to complete the rest of the
installation tasks. Both Crosstubes need to be raised the same amount, to the same Safety Lock.

To raise the Crosstubes:

1. Using a Forklift or Shop Crane,

Move the Crosstubes up enough so that you can work under the Runways (when you install them),
which makes it easier to route the Cables, Return Line, Air Lines, and Hydraulic Hose.

Important: Because the Cables are not in place yet, the Slack Safeties are going to engage when

you manually raise the Crosstubes. They cannot stay engaged as you continue with the
installation; you need to disengage them right after you raise the Crosstubes. The
Primary Safeties are not impacted; they will engage normally when you manually raise
each Crosstube, which is what you want.

carefully

raise each Crosstube.

2. To disengage the Slack Safeties after raising a Crosstube, press the Sheave and/or the Steel Piece
(they are connected and will move together) back towards the Ladder and the back of the Post.

3. Once both Crosstubes are in position, all Primary Safeties are engaged, and the Slack Safeties
have been disengaged, you can continue with the installation.

3. Put the Spacer into position between the Ladder and the back of the Post.

4. Push the Bolt through the Spacer and then through the back of the Post.

5. Take the second Washer and the Nut and install them on the end of the Bolt; secure the Nut.

6. Perform the same procedure to secure the other three Ladders on the Lift.

Note: Do not securely tighten the Top Nut at the top of the Top Cap at this point. The Top Nut

and the Stop Nut will be used later to make sure the Lift is level. They can be securely
tightened after you do the final leveling of the Lift; refer to Final Leveling for additional
information.

HDS-18EA Alignment Lift 23 P/N 5900970 — Rev. C2 — March 2020

Installing the Runways

Your Lift has two Runways:

• Powerside Runway: Has the Lift’s Hydraulic Cylinder underneath it. Gets bolted into position.
Has a hole on the outside (near the Front of the Lift) that lets you route the Hydraulic Hose, Air
Lines, and Return Line to the Power Unit. Cable routing starts under the Powerside Runway.

• Offside Runway: Is not bolted into position, so you can adjust the width between Runways; the
Stop Block prevents it from moving too far to the middle.

Orient the two Runways this way:

• Turn Plates at the Front of the Lift (the end opposite the Ramps)

• Utility Rails on the inside

This puts the Powerside Runway on the left and the Offside on the right, which is what you want.

You can double check this by:

• Looking under the Runways. Only the Powerside Runway has a Hydraulic Cylinder underneath.

• Finding the ~1.5-inch wide hole in the side of the Powerside Runway at the Power Post. There is
only one hole, it is only on the outside of the Powerside Runway, and it is next to the Power Post.

The following drawing shows the correct orientation of the Runways.

HDS-18EA Alignment Lift 24 P/N 5900970 — Rev. C2 — March 2020

Use a Forklift or Shop Crane to raise the Runways and move them into position.

⚠ WARNING Pay close attention when moving the Runways into position; they are extremely

heavy and long, which means they are awkward to move and could shift position or
fall, potentially causing serious injury.

To install the Runways:

1. Check the two Runways so that you know which is the Powerside Runway and which is the
Offside Runway.

See the previous page for more information.

2. On the Powerside Runway, remove the Cable Sheaves at both ends.

To remove the Cable Sheaves: unscrew the Sheave Pin Lock Screw (on the top of the Sheaves)
and pull out the Sheave Pin, then remove the Cable Sheaves from underneath the Runway.

There are four Cable Sheaves at the Rear of the Lift (the Ramp end) and two Cable Sheaves at the
Front of the Lift. You need to remove all six.

Note: Keep all of the components nearby, you will be putting them back in shortly.

3. When all six Cable Sheaves have been removed, use a Forklift or Shop Crane to pick up the
Powerside Runway and move it into place on top of the two Crosstubes on the Powerside of the
Lift.

Make sure the Utility Rail is on the inside

4. Bolt the Powerside Runway into place: two Bolts/Nuts on each end.

These Bolts go into the Crosstube from the outside and through the Runway structure; the Nut
goes on under the Runway.

5. Using a Forklift or Shop Crane, pick up the Offside Runway and move it into place on top of the
two Crosstubes between the Stop Blocks and the Crosstube Gusset.

Make sure the Utility Rail is on the inside

The Offside Runway does not have any Cable Sheaves that need to be removed, nor does it bolt
into place.

6. Double check all Safety Locks to make sure they are still engaged.

You do not want anyone going under the Runways unless the Safety Locks are engaged.

.

.

⚠ WARNING Do not continue with the installation until you have visually confirmed that all four

Safety Locks are engaged. If they are not engaged, the Runways could move or
fall, possibly causing personal injury or product damage.

HDS-18EA Alignment Lift 25 P/N 5900970 — Rev. C2 — March 2020

Installing the Flex Tube

The Flex Tube is a flexible, black tube that attaches to a hole on the Powerside Runway on one end
and to the bottom of the Flex Tube Bracket Plate (near the Power Unit) on the other end.

The Flex Tube is 52 inches (1,320 mm) long. The flexible tubing is about 1.5 inches (38 mm) wide. The
connectors on each end about 1.75 inches (44.5 mm) wide. Both ends are the same, so it does not
matter which end attaches where on the Lift.

The Flex Tube consolidates and protects three different cables that come out from under the
Powerside Runway on their way to the Power Unit. These cables are:

• Return Line. A thin, black tube that returns extra Hydraulic Fluid to the fluid reservoir on the
Power Unit.

• Air Line. Also a thin, black tube, the Air Line provides air pressure that is used to disengage the
Safety Locks so that the Runways can be lowered.

• Hydraulic Hose. A heavy, black cable that routes Hydraulic Fluid from the Power Unit to the
Hydraulic Cylinder.

Installation of the Flex Tube is usually done in two parts: one end is installed after the Powerside
Runway is installed (now), the other end after the Power Unit (and the Flex Tube Bracket Plate) is
installed (later in this installation).

The following drawing shows the Flex Tube.

To install the Flex Tube to the Powerside Runway:

1. Unscrew the Plastic Nut from one end of the Flex Tube.

2. Holding the Flex Tube by the Plastic Collar, put the Threads on the end of the Flex Tube whose
Plastic Nut you just removed through the hole on the Powerside Runway.

3. On the inside of the Powerside Runway, screw the Plastic Nut back onto the Threads of the Flex
Tube and tighten it.

4. Let the other end of the Flex Tube hang in place until the Flex Tube Bracket Plate is installed.

Working with Compression Fittings and Tubing

Your Lift comes with a roll of ¼ inch, black, polyethylene Tubing (also called Poly-Flo® Tubing) that is
used with Compression Fittings in two ways: for the Return Line and for the Air Lines.

Important: While both lines use Tubing and Compression Fittings, the Return Line and Air Lines

are used for completely separate purposes; do not connect the two together.

Note: Compression Fittings are different from Hydraulic Fittings. This section covers Compression

Fittings only.

The components involved with Compression Fittings include:

• ¼ inch, black, polyethylene Tubing. You use a single piece of Tubing for the Return Line.
The Air Lines require multiple Tubing pieces. Create the Tubing pieces for both the Return Line and
the Air Lines by cutting lengths from the roll of Tubing supplied with your Lift.

• Elbow Compression Fittings. The Return Line uses two
each end.

• Tee Compression Fittings. The Air Lines require three

• Nuts, Ferrules, Rods, and Threads. Each connector on Elbow and Tee Compression
Fittings have a Nut, Ferrule, Rod, and Threads (see drawing below). The Nut holds the Tubing and
Fitting together. The Ferrule compresses when you tighten the Nut on the Threads to make a
secure connection. The Rod goes inside the Tubing so that nothing leaks out.

To connect Tubing to a Compression Fitting:

1. Push the Tubing through the Nut and over the Rod.

Do not push hard; you only need the Tubing to go a little way over the Rod. You cannot see the
Ferrule at this point, but the Tubing must go through the Ferrule and over the Rod.

2. Slide the Nut on the Tubing
from the Threads and then slide it away from the Fitting. See the drawing above.

3. Slide the Ferrule over the Tubing, away from the Fitting and towards the Nut.

4. With the Nut and the Ferrule out of the way, push the Tubing further over the Rod until it stops.

Installing the Return Line

The Return Line takes excess Hydraulic Fluid coming out of the Hydraulic Cylinder and sends it back
into the Fluid Reservoir on the Power Unit.

The Return Line is a single piece of ¼ inch, black, polyethylene Tubing with Elbow Compression
Fittings on each end. You need to cut off a piece of the supplied Tubing — of the right length — to
create the Return Line.

Important: The Return Line uses the same ¼ inch, black, polyethylene Tubing as the Air Lines. Be

sure not to confuse the two; the Return Line and the Air Lines do completely different
things and must be kept separate from each other.

The following drawing shows where the Return Line connects on the Lift.

HDS-18EA Alignment Lift 28 P/N 5900970 — Rev. C2 — March 2020

This step does not apply to installing the Return Line, but it does need to be done at this
point in the Lift installation.

The following drawing shows the Return Line.

Drawing not to scale. Some components not shown. Some components exaggerated.

To install the Return Line:

1. Attach an air pressure source to the Return Line Connector on the Hydraulic Cylinder and extend
the Cylinder’s Piston and Tie Plate until it is fully extended towards the Power Post.

Do not exceed 50 PSI

pulling device (such as a Come Along Tool) to extend the Piston and Tie Plate. Be careful not to
damage the Piston or the Tie Plate.

2. Measure the distance from the Return Line connector on the Hydraulic Cylinder to the Return Line
connector on the Power Unit.

3. Cut a piece of Tubing to the measured length from the roll of Tubing that comes with the Lift.

It is better to cut the Tubing a little too long rather than a little too short.

4. Route the Tubing from the Hydraulic Cylinder, through the Flex Tube, and out of the other end of
the Flex Tube next to where the Power Unit will be installed (see the drawing on the previous
page).

5. Remove the Shipping Plug from the Return Line Connector on the Hydraulic Cylinder.

6. Connect and tighten the threaded end of an Elbow Compression Fitting into the opening where the
Shipping Plug used to be.

7. Connect one end of the Return Line to the Elbow Compression Fitting you just installed.

Refer to Working with Compression Fittings and Tubing for instructions.

8. Leave the Power Unit end of the Return Line hanging out of the Flex Tube for now.

To install the Air Lines:

1. Find the roll of supplied ¼ inch, black, polyethylene Tubing and three Air Line Tee Connectors.

2. Measure the distances for each of the seven (7) Tubing pieces you will need (see the drawing on
the previous page) for the Air Lines.

3. Cut seven pieces of Tubing to the measured lengths from the roll of Tubing.

4. Connect the various pieces of Tubing to the Air Line Tee Connectors on the Lift, as shown in the
drawing on the previous page.

Make sure to position the three Air Line Tee Connectors as shown in the
drawing

Also make sure to route the long Tubing piece that goes under the Powerside Runway through the
Retaining Rings. This is done to keep the Air Lines out of the way of where the Cables will be
routed.

.

⚠ WARNING Make sure to route the Tubing pieces on the

Crosstubes through the Steel Tubes. This keeps the Tubing and the Tee
Connectors from being disturbed as you use the Lift. This is important, because if
the Air Lines are disturbed, the Safety Locks on the Lift may not work correctly. If
you notice that Tubing has become disconnected from an Air Line Tee Connector,
take the Lift out of service and get the Air Lines fixed.

Refer to Working with Compression Fittings and Tubing for more information about
connecting the Tubing to the Air Line Tee Connectors.

IMPORTANT! PLEASE READ NOW

Hydraulic Fluid Contamination

Hydraulic Fluid Contamination poses a
or other debris can get into the Hydraulic Hoses and Fittings on your Lift, making your new Lift
inoperable.

Your Lift is shipped with clean components; however, BendPak strongly recommends that you take
secondary precaution and clean all Hydraulic Hoses and Fittings prior to making connections. It is
better and less costly to take these extra steps now so that you do not need to take your Lift out of
service later to fix issues that could have been prevented at the time of installation.

There are several ways to clean Hydraulic Hoses and Fittings:

• Compressed Air. Use an air compressor to blow out contaminants from each Hydraulic Hose
and Fitting prior to installation. Clean, dry air is preferred. Wear eye protection (safety glasses,
goggles, or face shield) when using compressed air for cleaning. Never point an air hose nozzle at
any part of your body or any other person.

• Fluid Flushing. As long as the Hydraulic Fluid is clean and compatible with the system fluid, you
can flush Hoses and Fittings to create turbulent flow and remove particulates. Always ensure that
the fluid itself is contaminant-free.

Some additional steps that will help keep the Hydraulic Fluid clean:

serious

issue for your Lift; contaminants such as water, dirt,

• Remove old thread seal tape. Some ports on the Hydraulic Cylinders are shipped with
temporary plugs secured with thread seal tape, so make sure to thoroughly remove any leftover
thread seal tape that may inadvertently enter the Hydraulic System.

• Use a liquid thread sealant only. Teflon paste-type thread sealant or Loctite™ 5452 thread
sealant is recommended for all NPT Fittings. Do not over tighten NPT Fittings or they may crack.
Never use thread seal tape on JIC Fittings or ORB O-Ring Fittings.

• Always use clean equipment. If you use a dirty bucket or funnel to transfer the Hydraulic Fluid
into the Hydraulic Fluid Reservoir, the contaminants will likely be introduced into the Fluid. When
using cleaning rags, use a lint-free rag.

• Proper storage. Keep the Hydraulic Fluid sealed in its container until ready for use; store the
Fluid in a clean, dry, and cool area.

• Cover the Hoses and Fittings. Before installation, do not leave the ends of the Fittings
exposed; the same applies for the Hydraulic Hoses. As a general rule, keep the Hydraulic Hoses
and Fittings capped and kept clean in a clean area until ready for use.

• Filter the new Hydraulic Fluid. Just because it is new does not necessarily mean it is clean.
Use an offline filtration cart or kidney loop system to make sure the Hydraulic Fluid is clean before
being transferred into the Hydraulic Fluid Reservoir (even using a heavy duty nylon mesh screen is
better than trusting what is left at the bottom of the barrel).

• Avoid mixing different types of Hydraulic Fluid. If Hydraulic Fluid needs to be replaced,
make sure to flush the Hydraulic System of the old Hydraulic Fluid before you add the replacement
Fluid; do not mix the two together.

HDS-18EA Alignment Lift 32 P/N 5900970 — Rev. C2 — March 2020

About Thread Sealants

We recommend using a Liquid Thread Sealant (like Loctite™ 5452 or similar PTFE Thread Sealant) to
seal the Hydraulic components on your Lift.

Liquid Thread Sealant lubricates and fills the gaps between the Fitting threads, and leaves no residue
that could contaminate the Hydraulic Fluid. Other types of Thread Sealants (like Teflon Tape) can shred
during installation or removal and eventually enter the Hydraulic System.

Thread Sealant is not the same as a

place to prevent them from loosening over time, and is not easily removed.

Thread Sealant can be used with most Hydraulic Fittings, although you probably only need to use it
with NPT connectors.

To apply Thread Sealant:

1. Make sure the Fittings and connectors you are going to use are clean and dry.

If you are adding Thread Sealant to a Fitting or connector that has already been used with a
different Sealant, use a wire brush to thoroughly remove the old sealant before adding more.

2. Apply a small amount of Thread Sealant to the first four threads of the Fitting.

Threadlocker

; Threadlocker holds assemblies tightly in

⚠ WARNING Always wear the proper protective equipment when handling Thread Sealant.

You only need a small amount because the sealant spreads to the other threads as it is tightened
into place.

If you put too much, the excess liquid will be pushed out when the Fitting is tightened; use a rag to
wipe the excess.

3. Tighten the Fitting into the connector; do

Installing the Hydraulic Hose

The Hydraulic Hose moves Hydraulic Fluid from the Power Unit to the Hydraulic Cylinder, which uses it
to raise the Runways.

To install the Hydraulic Hose, you will need:

• The Hydraulic Hose. The Curved end attaches at the Hydraulic Cylinder and the Straight end
comes out the Flex Tube so that it can attach at the Power Unit.

• One JIC to NPT hydraulic fitting. The JIC end attaches to the Curved end of the Hydraulic
Hose and the NPT end to the Hydraulic Cylinder.

• One JIC to ORB hydraulic fitting. The JIC end attaches to the Straight end of the Hydraulic
Hose and the ORB end to the Power Unit.

The following drawing shows where the Hydraulic Hose goes on the Lift.

Drawing not to scale. Not all components shown.

HDS-18EA Alignment Lift 34 P/N 5900970 — Rev. C2 — March 2020

The following drawing shows the Hydraulic Hose and its connectors in more detail.

To install the Hydraulic Hose:

1. Find the Hydraulic Hose and the two Hydraulic Fittings (one JIC-to-NPT, one JIC-to-ORB).

2. Clean the Hydraulic components using the information in Hydraulic Fluid Contamination.

3. Take the Straight end of the Hydraulic Hose and, starting at the Hydraulic Cylinder, route the
Straight end through the Retaining Rings and the Flex Tube.

When you are done, the Straight end should be coming out of the Flex Tube near the Power Unit.

4. On the Hydraulic Cylinder, remove the Shipping Plug from the connector at the Piston Rod end.

5. Attach the NPT connector on the JIC-to-NPT Fitting to the connector on the Hydraulic Cylinder
where you just removed the Shipping Plug.

Tighten until secure.

Leave the JIC connector pointing up; this will help keep the Hydraulic Hose up and away from
where the Cables will be routed.

6. Attach the Curved end of the Hydraulic Hose to the JIC connector that is facing up.

Tighten until secure.

7. Leave the Straight end of the Hydraulic Hose coming out of the Flex Tube; do not connect it to the
Power Unit at this point.

Note: The ORB connector of the JIC-to-ORB Fitting will be connected to the Power Unit later in the

installation.

Routing the Cables

Before routing the Cables on your Lift, you need to know the following:

• BendPak strongly recommends using gloves when working with the Cables.

• The Lift has four Cables. All four are different lengths; they can only be used to make one

Runway, comes attached to the end of the Piston Rod on the Hydraulic Cylinder.

• The Button end of each Cable connects at the Tie Plate on the underside of the Powerside
Runway. The Button ends of each Cable stay on one side of the Tie Plate (as shown above), while
the rest of the Cable goes through the Tie Plate and the Retaining Plate on its way towards the
appropriate Sheaves and then to the Post to which it attaches.

• The Threaded end of each Cable goes around the appropriate Sheaves and then gets routed to a
Post, where it is attached at the top. Before routing each Cable, remove the Nut at the Threaded
end; you cannot route the Cable around the Sheaves if the Nut is still on.

• The Lift comes with a Retaining Plate on one side of the Tie Plate. The Retaining Plate holds the
Button ends in place after all four Cables are installed. Do not take the Retaining Plate off to install
the Cables; instead, loosen it so that you can slip the Button end of the Cable into the correct slot.
When all four Cables are installed, tighten the Retaining Plate.

• There are two kinds of Sheaves: Cable Sheaves and Gusset Sheaves. There are four Cable
Sheaves at the Rear of the Powerside Runway and two Cable Sheaves at the Front of the
Powerside Runway, for a total of six Cables Sheaves for the Lift. There are four Gusset Sheaves,
one per Crosstube Gusset.

• The Cable Sheave
holds two Sheaves, has two lubrication holes inside it. The Cable Sheave Pin at the Rear of the Lift,
which holds four Sheaves, has four lubrication holes in it. Be sure to reinstall the Cable Sheave
Pins in their correct locations. Note that they look the same on the outside, so be sure to use the
right one.

• A Cable and its corresponding Cable Sheave (or Sheaves) are put into place one at a time, starting
from the Tie Plate to the top of the Post. Cables and their Cable Sheaves must be put into place at
the same time. Do not install the next Cable/Cable Sheave pair until the previous Cable/Cable
Sheave pair are in place.

• Each Crosstube Gusset has a Cable Lock Pin just under the bottom of the Gusset Sheave. Each
Cable Lock Pin needs to be removed when you are routing the Cable for the applicable Post.
Reinstall the Cable Lock Pin once the Cable is in place.

The Cable Lock Pin prevents the Cable from coming out later; there is not enough space between
the bottom of the Gusset Sheave and the Cable Lock Pin for the Cable to slip out.

• In the drawings on the following pages, the Cables and Cable Sheaves are labelled A, B, C, and D.
These letters indicate the order in which they are put into place. Cable A and Cable Sheave A are
put into place first, then Cable B and Cable Sheave B, and so on. These letters are
label on the Threaded end. You have to match the Cable letter with the length information.

The Cable Sheave letters apply to the four Cable Sheaves at the Rear of the Lift. There are also
two Cable Sheaves at the Front of the Lift; they are associated with Cables C and D.

• The order in which the Cables and Sheaves are put into place is based on the order the Cable
Sheaves must be replaced. By coincidence, the Cables for the HDS-18EA are installed shortest to
longest; this is true of some, but not all, BendPak Lifts.

• The four Cables for the HDS-18EA are:

o A: 4127 mm / 13.5 feet / 162.5 inches (part number 5595835)

o B: 5855 mm / 19.2 feet / 230.5 inches (part number 5595836)

o C: 10483 mm / 34.5 feet / 412.75 inches (part number 5595806)

o D: 12215 mm / 40 feet / 481 inches (part number 5595807)

Important: Make sure to use the correct Cable for each routing. If you put a Cable in the wrong

place, you will be able to route it, but eventually it will be too short or too long.
Remember that the length of each Cable is printed on the label on the Threaded end.

• All four Cables start at the Tie Plate and then go around a Cable Sheave at the
Cables A and B then go to the Gusset Sheave at the bottoms of the Posts to which they attach.

Cables C and D start at the Tie Plate, go around a Cable Sheave at the Rear of the Lift, are routed
to the Front of the Lift where they go around another Cable Sheave, and then go to the Gusset
Sheave at the bottoms of the Posts to which they attach.

In summary: Cables A and B go through one Cable Sheave and one Gusset Sheave. Cables C and
D go through two Cable Sheaves and one Gusset Sheave.

should not be exposed to flammable vapors. Never expose the Power Unit motor
to rain or other damp environments. Damage to the motor caused by water is
covered by the warranty.

We recommend installing all of the following components at the same time:

• Power Unit. Connects to an electric power source, provides Hydraulic Fluid to the Hydraulic
Cylinder so that the Runways can be raised.

• Vibration Dampener. Isolates the Power Unit from vibrations from the Lift coming through the
Power Post. Connect all four corners.

• Flex Tube Bracket Plate. Holds one end of the Flex Tube near the Power Unit so that the
Hydraulic Hose, Return Line, and Air Line can make their connections. Attach the end with the two
slots when you install the Power Unit.

• Zero Angle Bracket. Holds the Pushbutton Air Valve. Attach the end with the single hole when
you install the Power Unit. The end with the two holes connects to the Pushbutton Air Valve.

Even though you are not connecting the Power Unit at this point, you can fill the Hydraulic Fluid
reservoir with fluid.

To install the Power Unit and other components:

1. Find the four supplied Hex Head Bolts, Flat Washers, and Nyloc Nuts, as well as the Power Unit,
Vibration Plate, the Flex Tube Bracket Plate, and the Zero Angle Bracket.

2. Inspect the Mounting Plate and the Back Plate of the Power Unit, then decide which locations you
are going to connect to each other.

There are multiple locations on the Back Plate of the Power Unit that you can use to attach to the
Mounting Bracket. Choose the ones that best center the Power Unit on the Mounting Bracket.

Tip The Power Unit is heavy. BendPak recommends having one person hold the Power Unit

while another person bolts it into place.

3. Arrange the four components in the desired order.

The following drawing shows a popular way to arrange the four components.

Drawing combines front and side view. Drawing not to scale. Not all components shown.

4. Connect the Back Plate of the Power Unit and the other components to the desired Mounting
Bracket on the Power Post using the Bolts, Washers, and Nuts.

5. Fill the Hydraulic Reservoir on the Power Unit with approved fluids.

The Hydraulic Reservoir holds approximately 7 gallons (26.5 liters). Use care to keep the fluid clean
when filling the reservoir.

Approved fluids are any general purpose ISO-32, ISO-46, or ISO-68 hydraulic fluid or approved

Do not connect the Power Unit to a power source at this point.

HDS-18EA Alignment Lift 46 P/N 5900970 — Rev. C2 — March 2020

Installing the Flex Tube

Once the Power Unit is installed, you can install the second end of the Flex Tube (the other end was
connected to the Powerside Runway earlier in the installation).

The Flex Tube consolidates and protects the lines that come out from under the Powerside Runway:
the Air Line, the Return Line, and the Hydraulic Hose.

To install the Flex Tube, you first need to connect the Flex Tube Bracket Plate and the Flex Tube Angle
Plate, if you have not yet connected them.

The components involved include:

• Flex Tube. Protects the Air Line, the Return Line, and the Hydraulic Hose. Connects to the hole
on the Flex Tube Angle Plate from underneath.

• Flex Tube Bracket Plate. The two notches at the top attach near the Mounting Bracket on the
Power Post. The two holes at the bottom connect to the Flex Tube Angle Plate.

• Flex Tube Angle Plate. Attaches to the Flex Tube Bracket Plate via two holes, giving you the
flexibility to connect it on either side. Includes the hole to which the Flex Tube connects.

BendPak recommends orienting the Flex Tube so that the lines coming out of it are near where they
connect on the Power Unit and to the Pushbutton Air Valve.

To install the Flex Tube:

1. Find the Flex Tube Angle Plate (if it is not already installed).

The Flex Tube is already nearby and the Flex Tube Bracket Plate should already be installed.

2. Connect the Flex Tube Angle Plate to the bottom of the Flex Tube Bracket Plate so that the hole
for the Flex Tube is best positioned for connecting the Return Line, the Air Line, and the Hydraulic
Hose.

The Flex Tube Angle Plate can be connected on either side of the Flex Tube Bracket Plate.

3. When the Flex Tube Angle Plate is in place, unscrew the Plastic Nut from the end of the Flex Tube.

4. Holding the Flex Tube by the Plastic Collar, put the Threads through the hole on the Flex Tube
Angle Plate

5. Screw the Plastic Nut back onto the Threads and tighten.

Installing the Pushbutton Air Valve

Once the Power Unit and the Flex Tube are installed, you can install the Pushbutton Air Valve, which
requires the Zero Angle Bracket (which should already be installed).

The Pushbutton Air Valve is used to lower the Runways. It can go on either side of the Power Unit,
whichever is easier to access for the Lift operator.

Once the pushbutton is in place, you need to connect it to the Air Line (which is coming out of the Flex
Tube) on one end and the customer-supplied air pressure on the other end.

pressure of 30 PSI / 3 CFM is required

The following drawing shows the Zero Angle Bracket and how and where it connects to the
Pushbutton Air Valve.

The components involved include:

• Zero Angle Bracket. Attaches at the Mounting Bracket on the Power Post or to other available
holes on the Back Plate of the Power Unit. Holds the Pushbutton Air Valve, so be sure to orient the
Zero Angle Bracket so that the Pushbutton Air Valve can be easily reached by the Lift operator.

• Pushbutton Air Valve. Used to lower the Runways.

• Air Line Compression Elbow Fitting. Connects the Pushbutton Air Valve to the Air Line
coming out of the Flex Tube.

• Straight Expander Fitting. Connects the Pushbutton Air Valve to the customer-supplied air
pressure. A minimum air pressure of 30 PSI / 3 CFM is required.

To install the Pushbutton Air Valve:

Anchoring the Posts

If you have not done so already, you need to anchor the Lift’s four Posts. Install one Anchor Bolt in
each corner of each Base Plate, 16 Anchor Bolts total.

Concrete specifications are:

• Depth: 4.25 inches thick

• PSI: 3,000 PSI, minimum

• Cured: 28 days, minimum

Anchor Bolt specifications are:

• Length: 4.75 inches

• Diameter: .75 inch

• Effective embedment: 2.75 inches

• Anchor torque: 85 – 95 pound feet (do not Torque less than 80 or more than 105)

⚠ WARNING Your Concrete and Anchor Bolts

BendPak Lifts are supplied with installation instructions and concrete fasteners meeting the criteria as
prescribed by the American National Standard “Automotive Lifts – Safety Requirements for
Construction, Testing, and Validation” ANSI/ALI ALCTV.

HDS-18EA Alignment Lift 54 P/N 5900970 — Rev. C2 — March 2020

To anchor the Posts:

1. Locate the hardware you will need: four Anchor Bolts, four Nuts, and four washers

2. Using the Base Plates as guides, drill the holes for the Anchor Bolts—one hole in each corner of
the Base Plate, so four holes total per Base Plate.

Go in straight, in the center of the hole; do not let the drill wobble.

Use a carbide bit (conforming to ANSI B212.15).

The diameter of the drill bit must be the same as the diameter of the Anchor Bolt. So if you are
using a ¾ inch diameter Anchor Bolt, for example, use a ¾ inch diameter drill bit.

3. Vacuum each hole clean.

4. Make sure the Washer and Nut are in place, then insert the Anchor Bolt into the hole.

The Expansion Sleeve of the Anchor Bolt may prevent the Anchor Bolt from passing through the
hole in the Base Plate; this is normal. Use a hammer or mallet to get the Expansion Sleeve through
the Base Plate and into the hole.

Even using a hammer or mallet, the Anchor Bolt should only go into the hole part of the way; this is
normal. If the Anchor Bolt goes all the way in with little or no resistance, the hole is too wide.

Once past the hole in the Base Plate, the Anchor Bolt eventually stops going down into the hole as
the Expansion Sleeve contacts the sides of the hole; this is normal.

5. Hammer or mallet the Anchor Bolt the rest of the way down into the hole.

Stop when the Washer is snug against the Base Plate.

6. Plumb each Post; install any needed Shims.

Do not shim a Post more than half an inch using the provided Shims. A maximum of 2 inches is
possible by ordering optional Shim Plates. Contact BendPak at [phone], extension 191

Final Leveling

Because you are installing an Alignment Lift, it is very important that the Lift’s Runways are level, or as
close to level as possible. The following procedure describes how to fine tune how level your Lift is.
The goal is that the four Safety Locks on the Lift engage at the same time.

To do final leveling on the Lift:

1. Raise your Lift to the first Safety Lock position.

2. Use a transit level or other leveling mechanism to evaluate how level the Posts and Runways are to
each other.

3. If you need to adjust a Runway, use the Top Nut and Stop Nut on the Top Cap of each Post to
make adjustments to the Ladder in that Post (which impacts the levelness of the Runway and thus
when the Safety Locks engage).

4. Raise the Lift to full height, listening as the Safety Locks engage.

If the Safety Locks are engaging at the same time, no further adjustments are necessary.

If the Safety Locks are not engaging at the same time, check the leveling, make necessary
adjustments, and then raise the Lift again and listen as the Safety Locks engage.

5. When you are satisfied the Lift is level, secure the Nuts at the top of each Post.

Installing Accessories

The accessories available for your Lift include:

• Tire Stops. Installed at the Front of the Lift. Hold the front Tires of the Vehicle in position.
BendPak recommends chocking the rear Tires, so that the Vehicle stays in place.

• Ramps. Installed at the Rear of the Lift. Allow Vehicles to be easily driven onto the Runways.

• Alignment Turn Plates. Installed at the Front of the Runways. Used for alignments.

Tire Stops

Tire Stops are bolted onto the Front of the Lift. They prevent the tires of the Vehicle on the Lift from
going too far forward.

To install the Tire Stops:

1. Locate the four Hex Head Bolts, Washers, and Nuts that you will need (two sets per Tire Stop).

2. Put one Tire Stop in position over the holes in the Runway, put the Bolt through the Tire Stop and
the holes in the Runway, then secure the Tire Stop with the Washer and Nut on the underside of
the Runway.

Note: Make sure to orient the Tire Stop so that it is sloping away from the Runways. This

creates an angle best suited to holding the Tire in place.

3. Repeat Steps 1 and 2 for the second Tire Stop.

HDS-18EA Alignment Lift 57 P/N 5900970 — Rev. C2 — March 2020

Ramps

Your Lift comes with two Ramps, which are installed onto the Rear of the Lift so that Vehicles can drive
onto the Runways.

To install the Ramps:

1. Find the required components: two Ramps, two Ramp Pins, and four 18 mm Rotor Clips.

2. Put a Ramp into position on the end of a Runway at the Rear of the Lift, with the tube on the
bottom of the Ramp between the two tubes on the end of the Runway.

3. Slide a Ramp Pin through the three tubes, then install Rotor Clips on both ends of the Ramp Pin.

Note: The Ramps are awkward, so you may want to consider having two people work together

to install them: one to hold the Ramp, the other to put the components into place.

4. Repeat Steps 2 and 3 for the other Ramp.

Alignment Turn Plates

Alignment Turn Plates are used for Vehicle alignments. They are used in conjunction with two Filler
Plates per Runway to fill the lowered space at the Front of the Lift.

To install the Alignment Turn Plates:

1. Find the required components: two Alignment Turn Plates and four Filler Plates.

2. Put one of the Alignment Turn Plates into place in the lowered space at the Front of one of the
Runways.

The Alignment Turn Plate can go in the front, middle, or back of the lowered space; the Filler Plates
go in the other locations.

Put the Alignment Turn Plate closer to the Front of the Lift (closer to the Tire Stops) if you are going
to be doing alignments on Vehicles with shorter wheel bases.

Put the Alignment Turn Plate in the middle of the lowered space if you are going to be doing
alignments on Vehicles with medium wheel bases.

For Vehicles with longer wheel bases (bigger trucks, for example), put the Alignment Turn Plate in
the space closest to the Rear of the Lift. This orientation is also useful for Vehicles with longer
fronts that would hang so far over the Front of the Lift that they interfere with the aligner.

Neither the Alignment Turn Plate nor the Filler Plates are bolted into place, making it easier to
adjust them when necessary.

3. Repeat Step 2 for the other Alignment Turn Plate and Filler Plates.

HDS-18EA Alignment Lift 58 P/N 5900970 — Rev. C2 — March 2020

Lubricating the Lift

There are six lubrication points on the Lift. All of them are where Sheaves are located:

• Four lubrication points on the Crosstube Gussets. One on each Crosstube Gusset, for a
total of four.

• Two above the Stacked Sheaves. One above the 4 Stacked Sheaves (on the Powerside
Runway at the Rear of the Lift) and another above the 2 Stacked Sheaves (on the Powerside
Runway at the Front of the Lift).

Put a small amount of white lithium grease or similar on each lubrication point before you use the Lift
and monthly after putting the Lift into service.

Bleeding the Hydraulic Cylinder

The Hydraulic Cylinder on the Lift is self-bleeding, which means that in most cases any air in the
system can be removed by raising and lowering the Runways a few times; “bleeding” the Hydraulic
System of the unwanted air.

⚠ WARNING Before performing any maintenance on your Lift (for example, bleeding the

Hydraulic Cylinder or adding Hydraulic Fluid), make sure both Runways are on the
ground and the power source has been disconnected.

Symptoms of air in the Hydraulic System include Runways moving erratically and/or making odd
noises. These could be caused by other situations; refer to Troubleshooting for more information.

To bleed the Hydraulic System:

1. Raise and lower the Runways up to six times;

each cycle

The Lift’s motor cannot run continuously; it is designed for regular use, but not continuous use.

2. Watch the Runways as you raise and lower them.

.

pause for at least one minute between

When the Lift stops moving erratically or stops squeaking, you can stop the bleeding process.

HDS-18EA Alignment Lift 59 P/N 5900970 — Rev. C2 — March 2020

3. Check the Hydraulic Fluid reservoir on the Power Unit.

Bleeding the Hydraulic System may significantly lower the amount of Hydraulic Fluid in the
reservoir.

4. Add additional Hydraulic Fluid if necessary.

If your Lift is still moving erratically or making odd noises after bleeding the Hydraulic System, refer to

Troubleshooting for more information.

Performing an Operational Test

BendPak strongly recommends doing an Operational Test of your Lift with a typical Vehicle before
starting normal service (a typical Vehicle is not required, but is recommended).

During the Operational Test, watch the Lift and its components and check for proper installation and
operation. If you run into an issue that does not go away, refer to Troubleshooting for more
information.

Note: Residual air in the Hydraulic System can cause the Lift to shake, move erratically, or

squeak when you start using it; this is normal. If it happens, do not worry; it will go away as
the Hydraulic System is self-bleeding. If it does not go away, refer to Troubleshooting
for additional information.

To test your Lift:

1. Check the area around, above, and under the Lift for obstructions; move them if you find any.

2. Drive the Vehicle onto the Lift. Try to center the Vehicle’s tires in the middle of each Runway.

Put the Vehicle into park, put on the parking brake, put it in gear if it is a manual transmission, and
chock the wheels.

3. Move the Raise/Lower Button to On, and hold it there (if you do not hold it, it returns to Off).

Both Runways start rising.

4. After the Runways pass one or two Safety Locks (you will hear them clank as they hit a Safety
Lock position), release the Raise/Lower Button. The Runways stop rising.

5. Press and hold the pushbutton on the Pushbutton Air Valve, then press and hold the Lowering
Handle.

The Runways start lowering.

6. When the Runways get all the way to the ground, release the Lowering Handle.

7. Wait for one minute.

⚠ CAUTION Always take a break between cycles. The Power Unit’s motor is

9. If the Lift is working without shaking, moving erratically, or squeaking, there is no need to repeat
the procedure.

If the Lift is shaking, moving erratically, or squeaking (which is normal during the start-up period),
repeat the procedure a couple more times, with at least a one-minute break between cycles.

If you continue to have issues, refer to Troubleshooting for assistance.

Safety Considerations

Do the following every time

• Check the Lift. Walk all the way around the Lift, checking for any missing, heavily worn, or
damaged parts. Do not operate the Lift if you find any issues; instead, take it out of service, then
contact your dealer, email [e-mail], or call [phone].

• Check the area. Keep the area around and under the Lift clean and free of obstructions;
anything that could cause a problem. Do not forget to check
obstruction, move it out of the way. If you find any other issues, resolve them before using the Lift.
Do not allow any people or animals within 30 feet of the Lift while it is in motion.

• Check the operators. Make sure everyone who is going to operate the Lift has been trained in
its use, has read the labels on the unit, and has read the manual. Only the operator at the Controls
should be within 30 feet of the Lift when it is in motion.

Do not allow children to operate the Lift. Do not allow anyone under the influence of drugs, alcohol,
or medication to operate the Lift. Do not allow any unauthorized personnel to operate the Lift.

• Check for safety. Make sure everyone who is going to be walking near the Lift is aware of its
presence and takes appropriate safety measures. Only put Vehicles on the Runways.

When raising a vehicle, do not leave it until it is engaged on a Safety Lock. When lowering the Lift,
do not leave it until it is on the ground.

• Check the vehicle. Never exceed the Lift’s weight rating. Do not allow people inside a Vehicle
you are going to raise. Make sure the Vehicle is not overbalanced on either end or either side.

Raising and Lowering Vehicles

Keep the following in mind when operating your Lift:

• Be safe. Make sure to check for people, pets, and objects that might be in the path of the Lift as

you raise or lower it. If there is something in the way, stop the Lift and move it out of the way.
Watch the Lift carefully as it raises and lowers.

⚠ DANGER Pay careful attention when you are raising or lowering your Lift. If a person or pet

gets stuck under the Lift, they could be injured or, in rare cases, killed. If a problem
arises, either stop the Lift or get it back to the ground, whichever is safest.

• The Power Disconnect Switch is there for a reason. We hope you never have to use it,
but if something unexpected happens, use the Power Disconnect Switch to immediately stop
the Lift from moving.

• Get what you need out of the Vehicle before lifting it. It is annoying to raise a Vehicle
and then realize you left something inside.

• Make sure the Vehicle is balanced. If there is extra weight on one end or the other, remove
the extra weight or balance it

• Center the Vehicle’s wheels on the Runway. Centered wheels keep the Vehicle balanced.

To raise a vehicle:

raising the vehicle.

.

1. Make sure the Runways are fully lowered. If they are not, move them down to the ground.

2. Drive a Vehicle onto the Runways.

Put the front wheels up against the Tire Stops. Make sure all four wheels are fully on the Runways,
as close to the center of the Runways as possible. Put the Vehicle into park and put on the parking
brake. If it is a manual transmission, make sure it is in a gear, not in neutral. Chock the tires.

3. Move the Raise/Lower Button to On, and hold it there.

If you release the Raise/Lower Button, it automatically returns to Off and the Lift will stop moving.

The Runways begin to rise.

4. When the Runways get to the desired height, go up a little bit more, release the Raise/Lower
Button, and then press and hold the Lowering Handle.

The Runways move down and engage on the most recently passed Safety Locks.

How do you know if one of the four Safety Locks has, for some reason, not engaged? If this
happens, the non-engaged corner of the Lift will continue to go down when you use the Lowering
Handle to back the Runways down onto the Safety Locks, while the others will engage on their
Safety Locks and stop moving. This results in a Runway that is not flat. Always check to make sure
that all four Safety Locks are engaged; you know they are if both Runways are completely flat.

⚠ WARNING: Only leave your Lift either engaged on Safety Locks or fully lowered.

5. With the Runways engaged on a Safety Lock, check around the Vehicle to make sure everything
looks good.

If you see anything wrong, fix it before anyone gets near the Runways or goes under them.

• Daily: Make sure all Safety Locks are in good operating condition. Do not use your Lift if the
Safety Locks are damaged or excessively worn.

• Monthly: Check all labels on the Lift. Replace them if they are illegible or missing.

• Monthly: Grease the lubrication points on the Lift. Use white lithium grease or similar.

• Monthly: Check Hydraulic Fluid levels. Refill if low.

• Monthly: Lubricate the wire rope (Cables). Use a wire-rope lubricant such as 90-WT gear oil or
ALMASOL® Wire Rope Lubricant.

• Every two months: Check all Anchor Bolts to make sure they are properly torqued. If they are
loose, tighten them.

• As needed. Take the Lift out of service and then replace the Cables if there are signs of damage
or extreme wear.

disconnected from power.

raised when you notice the damage or extreme wear, very carefully lower the
Vehicle to the ground. When the Lift is on the ground, take it out of service,
disconnect it from power, and make arrangements to fix the damage or wear.

⚠ WARNING: Do not operate your Lift if you find maintenance issues; instead, take the Lift out of

service, then contact your dealer, visit bendpak.com/support, email

[e-mail], or call [phone].

HDS-18EA Alignment Lift 65 P/N 5900970 — Rev. C2 — March 2020

Wire Rope Inspection and Maintenance

Your Lift’s Cables, which are wire rope, should be inspected regularly:

• Wire rope should be replaced when there are visible signs of damage or extreme wear. Do not use

the Lift if it has damaged or worn Cables;

• Wire rope should be maintained in a well-lubricated condition at all times.

Wire rope is only fully protected when each wire strand is lubricated both internally and externally.
Excessive wear shortens the life of wire rope. Use a wire-rope lubricant that penetrates to the core
of the rope and provides long-term lubrication between each individual strand, such as 90-WT
gear oil or ALMASOL® Wire Rope Lubricant. To make sure that the inner layers of the rope remain
well lubricated, lubrication should be done at least every three months during normal operation.

take it out of service!

• All Sheaves and guide rollers that contact moving wire rope should be given regular visual checks
for surface wear and lubricated to make sure they run freely. This should be done every three
months during normal operation.

For all sheave axles, use standard wheel bearing grease. For all Sheaves and/or guide rollers, use
90-WT gear oil or a similar heavy lubricant, applied by any method including pump/spray
dispensing, brush, hand, or swabbing.

• How often should you inspect?

Wire rope should be visually inspected at least once each day when in use, as suggested by
American Petroleum Institute’s Recommended Practice 54 guidelines. Any wire rope that meets
the criteria for removal must be immediately replaced.

• When should you replace wire rope due to broken wires?

Wire rope should be removed from service if you see six randomly distributed broken wires within
any one lay length (where a single strand makes a full turn around the rope) or three broken wires
in one strand within one lay length.

• Are there other reasons to replace your wire rope?

Yes. Corrosion that pits the wires and/or connectors, evidence of kinking, crushing, cutting, bird­caging, or a popped core, wear that exceeds 10% of a wire’s original diameter, or heat damage.

• How do you find broken wires?

a. Relax your rope to a stationary position and move the pick-up points off the Sheaves. Clean

the surface of the rope with a cloth — a wire brush, if necessary — so you can see any breaks.

b. Flex the rope to expose any broken wires hidden in the valleys between the strands.

c. Visually check for any broken wires. One way to check for crown breaks is to run a cloth along

the rope to check for possible snags.

d. With an awl, probe between wires and strands and raise any wires that appear loose.

Problem with the Air Lines; check to make sure all sections of
the Air Line are connected and not leaking.

The Safety Lock on the lower corner is not engaged. Raise the
Runways up, then lower them down onto the Safety Locks.
Check to make sure all four Safety Locks are engaged.

Move the Runways up and down a few times to flush any
residual air from the Hydraulic System. Make sure to pause for
at least two minutes between cycles.

Runways do not stay up. Check for leaking Hydraulic Fluid.

Make sure the Runways are left on their Safety Locks.

Motor not running. Check the connection to the power source; make sure it is

plugged in and of the appropriate voltage.

Check the wiring diagram.

Hydraulic Fluid is dirty. Replace the dirty fluid with clean, approved Hydraulic Fluids,

such as Dexron III, Dexron VI, Mercon V, Mercon LV, Shell
Tellus S4 / S3 / S2, or comparable.

Runways make odd noises. Lubricate the bushings on the sheaves on the sides of the

Crosstubes using white lithium grease. If the Lift is new, a
break-in period may be needed; run the Lift several times
each day. If the noises persist, contact BendPak Support.

If you continue to have issues with your Lift, take it out of service, then contact your dealer, go to

bendpak.com/support, email [e-mail], or call [phone].
