Brackets on it. Mount the Power Unit on one of the two Mounting Brackets.

• The other three Posts. These Posts are functionally interchangeable; their Labels are different.

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

• Lifting Cables. The two Runways are lifted by .4 inch / 10 mm thick aircraft-quality steel wire
rope, each of which is rated at 14,400 pounds.

• Boat Trailer Tongue Platform (TC-3000 model). Sits between the Runways, holds the front
wheel of your boat trailer.

• Powerside Runway. The Runway next to the Power Post. The Powerside Runway has Lifting
Cables and the Hydraulic Cylinder on its underside. You

• Offside Runway. The other Runway. It does not have a Hydraulic Cylinder or Lifting Cables
under it.

• Utility Rails. Hold the optional Rolling Jacks. Utility Rails

• Crosstubes. One at each end of the Lift. The Crosstubes are hollow; the Lifting Cables that raise
and lower the Runways are routed through the Crosstubes. The Crosstubes are not the same:
each Crosstube has an opening (called a Window) that faces the inside (orienting the Windows
correctly is described in the Installation section).

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

• Ramps. One for each Runway. Use them to drive onto and off of the Runways. By definition, the
Ramp end of the Lift is also the Rear of the Lift.

• 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.

• 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.

The Lift supports less weight than its rated capacity when the Vehicle’s wheelbase is shorter; this is
because the wheels 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 95 inches is 50 percent of the
Lift’s rated capacity or 3,750 lbs with a rated capacity of 7,500 lbs.

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 7,500 lbs (3,402 kg).

Q: How long does it take to raise or lower my Lift with a Vehicle on it?

A: About 45 to 55 seconds, depending on your model. Longer if there is no weight on it.

Q: Does the Lift have a Front and a Rear?

A: Yes. For a Four-Post Lift, the end

the Rear.

Q: Do I have to put my Power Unit in a particular location?

A: Yes. Your Power Post (the Post the holds the Power Unit) must be located at either the Driver-

Side Front or the Passenger-Side Rear of the Lift. More on this later.

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

A: Yes. BendPak strongly recommends that you anchor the Lift; it may be less stable if you do not

anchor the Bases.

Q: How high does the ceiling have to be?

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

the Runways. If you are going to put a tall Vehicle or Boat on the Lift and raise it all the way up,
you should check to make sure there is enough room.

opposite

the Ramps is the Front; the end with the Ramps is

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

wheels on the Runways. But it is up to you; the Lift works great either way. Also, remember to put
the Front wheels up against the Tire Stops and chock the Rear wheels.

Q: Will the Lifting Cables really hold my Vehicle?

A: Yes. Each Lifting Cable is .4 inches thick, aircraft-quality steel

Q: Do I need an Air Supply?

A: Yes. An Air Supply (3 to 25 cfm at 50 to 150 psi) is required to disengage the Safety Locks when

you want to lower the Lift. Regulate the line to a maximum pressure of 150 psi; the Air Lines could
burst or the Safety Locks malfunction at pressures over 150 psi.

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

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

loss of power or a leaking Hydraulic Hose will not affect the Lift.

Q: Can I install my Lift outside?

Being Safe

While installing this equipment, your safety depends on proper training and thoughtful operation.

⚠ WARNING Do not install this equipment unless you have automotive Lift installation training.

Always use proper lifting tools, such as a Forklift or Shop Crane, to move heavy
components. Do not install this equipment without reading and understanding this
manual and the safety labels on the unit.

Only fully trained personnel should be involved in installing this equipment. Pay attention at all times.
Use appropriate tools and lifting equipment. Stay clear of moving parts.

BendPak recommends referring to the current version of the ANSI/ALI ALIS Standard Safety
Requirements for Installation and Service for more information about safely installing, using, and
servicing your Lift.

⚠ WARNING You must wear appropriate protective equipment

gloves, steel-toe work boots, eye protection, back belts, and hearing protection.

Tools

You may need some or all of the following tools and supplies:

• Rotary hammer drill (or similar)

• ¾ inch carbide bit (conforming to ANSI

B212.15)

• Hammer, crow bar, and two sawhorses

HD-7500 Series Four-Post Lifts 12 P/N 5900174 — Rev. C1 — February 2022

Planning for Electrical Work

You will need to have a licensed, certified Electrician available at some point during the installation.

⚠ DANGER All electrical work

Notify your Electrician in advance so that they come prepared with appropriate components for
connecting to the power source, a Power Disconnect Switch, and a Thermal Disconnect Switch. Refer
to Contacting the Electrician for more information.

Your Electrician needs to:

• Connect the Power Unit to an electric power source. An electric power source is
required. The Power Unit comes with a Pigtail for wiring to a power source. Have your Electrician
connect a power cord with appropriate plug to the electrical box on the Lift (for connection to a
power outlet) or have them wire it directly into the electrical system at the Lift location.

Note that installing the Power Unit and connecting the Power Unit to the power source are
separate procedures and are done at different times in the installation process. You do
an Electrician to install the Power Unit, but an Electrician is
the power source.

• Install a Power Disconnect Switch. This switch ensures you can quickly and completely
interrupt electrical power to the Lift in the event of an electrical circuit fault, emergency situation, or
when equipment is undergoing service or maintenance. Put it within sight and reach of the Lift
operator.

• Install a Thermal Disconnect Switch. This switch ensures the equipment shuts down in the
event of an overload or an overheated motor.

Note: These components are not supplied with the Lift.

Selecting a Power Post Location

You need to pick a Power Post location now, near the beginning of the installation process, as its
location impacts other aspects of the installation.

You have two options for Power Post location: Driver-Side Front or Passenger-Side Rear.

Note: The Power Post location decision has no impact on the Approach direction or where the

Front and Rear of the Lift are. It does impact other aspects of the installation, however.

Most customers choose their Power Post location based on either preference (one option makes more
sense for their shop than the other does) or easier access to the power source.

Selecting a Location

When selecting the location for your Lift, consider:

• Architectural plans. Consult the architectural plans for your desired installation location. Make
sure there are no issues between what you want to do and what the plans show.

• Available space. Make sure there is enough space for the Lift: front, back, sides, and
Refer to Specifications for measurements.

• Overhead obstructions. Check for overhead obstructions such as building supports, heaters,
electrical lines, low ceilings, hanging lights, and so on.

Lift hitting obstructions

• Side and front clearances. You must leave room around the Lift. Leave at least six feet (72
inches / 1.8 meters) clear on both sides and the front of the Lift, and no obstructions at all at the
Rear of the Lift (so you can safely drive Vehicles onto the Runways).

• Power. You need an appropriate power source for the Power Unit.

• Outdoor installations. Your Lift is approved for indoor installation and use

• Floor. Only install the Lift on a flat, Concrete floor; do not install on asphalt or any other surface.
The surface must be level; do not install if the surface has more than three degrees of slope.

⚠ WARNING Installing your Lift on a surface with more than three degrees of slope could lead to

injury or even death. Only install the Lift on a level floor. If your floor is not level,
consider making the floor level or using a different location.

• Shimming. If your Concrete floor is not completely level, you can use Shims under the bases of
the Posts, as needed, to level the Lift.

To estimate your Shim requirements, use a transit level and targets to check for flatness. Use the
provided Shims as necessary.

NOTICE Do not shim a Post more than half an inch using the provided Shims and Anchor Bolts.

A maximum shim of 2 inches is possible by ordering optional Shim Plates. Contact
BendPak at [phone], extension 191 to order.

• Concrete specifications. Do not install the Lift on cracked or defective Concrete. Make sure
the Concrete is at least 4.25 inches thick, 3,000 PSI, and cured for a minimum of 28 days. Do not
install Anchor Bolts within six inches of cracks, expansion joints, or other defects in the Concrete.

⚠ CAUTION BendPak lifts are supplied with installation instructions and Concrete anchors that

meet the criteria set by the current version of the American National Standard
“Automotive Lifts – Safety Requirements for Construction, Testing, and Validation”,
ANSI/ALI ALCTV. You are responsible for any special regional structural and/or
seismic anchoring requirements specified by any other agencies and/or codes such
as the Uniform Building Code (UBC) and/or International Building Code (IBC).

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 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
can shift or even fall. If they fall on a person, they could cause serious injury.

Installing the Crosstubes

Your Lift has two Crosstubes;

• One with Two

installed at the Cable Retainer Block end of the Powerside Runway.

• One with Two

installed adjacent to the Power Post.

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

Tip It is possible to install the Crosstubes incorrectly in several different ways. Take your

time and get it right the first time.

About Slide Blocks

The black Slide Blocks in the corners on the ends of the Crosstubes come installed from the factory. If
they fall off or do not come installed, put them into place so that each pair creates a Slot into which the
Ladder for each Post will be installed later in the installation procedure.

In the drawings below, the drawing on the left shows how two Slide Blocks get put into position; the
drawing on the right shows the Slot created by the two Slide Blocks when they are installed. There are
two Slots per Crosstube Gusset, one at the top and one at the bottom.

Safety Locks at a desired height,
check to make sure that all four
Safety Locks are engaged at the

So how do the Runways come down if the Primary Safety Locks are engaged? To lower the Runways,
you raise them a few inches (to get them off the Primary Safety Locks), then
Pushbutton Air Valve. While you hold down the pushbutton, the Primary Safety Locks are moved away
from the Safety Lock holes in the Ladders; they are prevented from engaging, which allows the
Runways to be lowered.

Out of abundance of caution, your Lift has a second, independent Safety Lock system called the Slack
Safety. In total, your Lift has two Safety systems:

• Primary Safety Locks. Located at the ends of each of the four Crosstubes, the Primary Safety

Locks hold the Runways in place once they are engaged. Primary Safety Locks are used over 99
percent of the time. Once engaged, Primary Safety Locks hold the Runways in place, even if the
power goes out or the Hydraulic Hoses break or leak.

• Slack Safety Locks. Also located at the ends of each of the four Crosstubes, the Slack Safety

Locks are a backup system in case any of the four Lifting Cables ever breaks (which is a rare
occurrence). During normal operation, the Lifting Cables prevent the Slack Safety Locks from
engaging, but if a Lifting Cable breaks while the Lift is not engaged on its Primary Safety Locks, the
Slack Safety Lock next to the broken Lifting Cable immediately engages at the next Safety Lock
position in the Ladder.

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

It is

not

necessary to slide the Ladders in from the very top of the Post.

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

Raising the Crosstubes

At this point in the installation you need to manually raise the Crosstubes, as this makes it easier to
complete the rest of the installation tasks. Both Crosstubes need to be raised the exact same amount,
to the exact same height.

To raise the Crosstubes:

1. Using a Forklift or Shop Crane,

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 (on the Cylinder end) that lets you route the Hydraulic Hose, Air Lines,
and Return Line to the Power Unit. Lifting Cable routing ends under the Powerside Runway.

• Offside Runway: Gets bolted into position. Does not have a Hydraulic Cylinder under it, nor are

there any Lifting Cables under it.

Orient the two Runways this way:

• Utility Rails on the inside

• Find the Powerside Runway by looking under the two Runways (only the Powerside Runway has a
Hydraulic Cylinder underneath it) and put it next to the Power Post.

• There is also a ~1.5 inch wide hole in the outside of the Powerside Runway near the Power Post.
There are other holes in the Runways, but they are smaller and used with accessories only.

The Ramp locations do not change based on Power Post location, but the location and orientation of
the Powerside Runway does.

The following drawing shows the correct orientation of the Runways for both Power Post locations.

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. Both ends of
the Flex Tube are the same.

The Flex Tube consolidates and protects three lines that come out from under the Powerside Runway
on their way to the Power Unit: the Return Line, the Air Line, and the Hydraulic Hose.

The following drawing shows the Flex Tube.

Not to scale. Not all components shown.

To install the Flex Tube to the Powerside Runway:

1. Remove and retain the Plastic Nut from one end of the Flex Tube. It does not matter which end.

2. Holding the Flex Tube by the Plastic Collar, put the Threads on the end of the Flex Tube through
the hole on the side of the Powerside Runway.

The following drawing shows the Flex Tube in place on the side of the Powerside Runway.

The Threads go into the hole until they are accessible from the inside, the rest of the Flex Tube
stays outside.

IMPORTANT! PLEASE READ NOW

Hydraulic Fluid Contamination

Hydraulic Fluid Contamination poses a serious issue for your Lift; contaminants such as water, dirt, or
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 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:

• 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.

HD-7500 Series Four-Post Lifts 37 P/N 5900174 — Rev. C1 — February 2022

About Thread Sealants

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 can be used with most Hydraulic Fittings, although you probably only need to use 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.

⚠ 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

4. Allow the manufacturer-recommended curing time before pressurizing the system.

work correctly until it is filled with approved Hydraulic Fluid.

⚠ WARNING Do not run your Power Unit without Hydraulic Fluid; you will damage it.

To fill the Reservoir with Hydraulic Fluid:

1. Remove the Reservoir Cap and set it aside.

Make sure to keep the Reservoir Cap clean; you do not want any contaminants getting into the
Hydraulic Fluid Reservoir.

2. Fill the Hydraulic Fluid Reservoir on the Power Unit with the appropriate amount of approved
fluids.

The Hydraulic Reservoir holds from 3.5 to 4.5 gallons, depending on your Power Unit:

– 5585280: 3.7 gallons / 14 liters

– 5585247: 3.7 gallons / 14 liters

– 5585106: 3.5 gallons / 13.25 liters

HD-7500 Series Four-Post Lifts 38 P/N 5900174 — Rev. C1 — February 2022

– 5585014: 3.7 gallons / 14 liters

Use care to keep the fluid clean when filling the reservoir.

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

3. Replace the Reservoir Cap.

Installing the Second End of 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).

To install the Flex Tube:

1. Find the Flex Tube Bracket Plate and the Flex Tube Angle Plate. The Flex Tube is already nearby.

2. Install the Flex Tube Bracket Plate.

Note: It is common to install the Flex Tube Bracket Plate between the Mounting Bracket and

the Back Plate. This allows the Zero Angle Bracket (which holds the Pushbutton Air Valve
and is described in the next section) to be installed between the Back Plate and the
retaining Nut. This configuration is common, but it is not required.

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 long roll of Tubing supplied with your Lift.

• Elbow Compression Fittings. The Return Line uses two Elbow Compression Fittings, one at

each end.

• Tee Compression Fittings. The Air Lines require three Tee Compression Fittings.

• 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.

The following drawing shows the components of a connector on a Tee Compression Fitting.

Important:

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.

Ferrules can only be tightened once

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

5. Slide the Ferrule and the Nut back to the Threads on the Fitting.

The Ferrule goes around the Rod and under the Threads. The Nut goes onto the Threads.

6. Tighten the Nut.

Remember that the Ferrule can only be used once; do not tighten the Nut until everything is
ready.

Installing the Pushbutton Air Valve

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 both the Air Line (which is coming out of the
Flex Tube) and the customer-supplied air pressure.

The following drawing shows the Pushbutton Air Valve and its connections.

HD-7500 Series Four-Post Lifts 41 P/N 5900174 — Rev. C1 — February 2022

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.

To install the Pushbutton Air Valve:

1. Find the necessary components: Zero Angle Bracket, Pushbutton Air Valve, Air Line Compression
Elbow Fitting, and Straight Expander Fitting.

2. Connect the Zero Angle Bracket at the desired location (if it has not already been connected).

It can attach to an available hole on the Back Plate of the Power Unit or to one of the Bolts that
connect the Power Unit to the Mounting Bracket on the Power Post.

3. Connect the Pushbutton Air Valve to the Zero Angle Bracket.

Use the two holes on the Pushbutton Air Valve on the side away from the actual pushbutton. If
you use the holes next to the pushbutton, the Zero Angle Bracket interferes with the pushbutton
when you try to use it.

4. Connect the Air Line Compression Elbow Fitting and the Straight Expander Fitting to the
appropriate locations on the Pushbutton Air Valve.

The elbow fitting connects to the opening labelled CYL. The straight fitting to the opening labelled
IN. See the drawing above.

5. Attach the Air Line (coming out of the Flex Tube) to the compression fitting on the elbow fitting
and the customer-supplied air to the straight fitting.

Important: The Return Line also comes out of the Flex Tube and is the same kind of tubing as the

Air Line.

Installing the Air Lines

This section describes how to install the Air Lines, but not how to connect them to the Power Unit (as
it is not yet installed).The Air Lines use air pressure to disengage the Safety Locks so you can lower the
Runways.

You will need more of the ¼ inch, black, polyethylene Tubing that came with the Lift and three Air Line
Tee Connectors to install the Air Lines.

An Air Supply (3 to 25 cfm at 50 to 150 psi) is required to disengage the Safety Locks. Regulate the
line to a maximum pressure of 150 psi.

⚠ CAUTION Do not let the Air Supply exceed 150 psi; the Air Lines could burst or the Safety

Locks malfunction.

Important: Do not confuse the Air Lines with the Return Line. They use the same Tubing and

fittings, but they are used for completely different things; the two systems
be connected to each other.

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).

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.

Refer to the drawing on the previous page for the locations of the Tubing pieces.

Also make sure to route the long Tubing piece that goes under the Powerside Runway through the
Retaining Rings. You need to make sure the Air Lines stay out of the way of the Lifting Cables.

.

⚠ CAUTION Make sure to route the Tubing pieces on the

Crosstubes through the Steel Tubes on the Crosstubes. 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.

5. Leave the Power Unit end of the Air Line hanging out of the Flex Tube for now.

It will be connected to the Pushbutton Air Valve later in the installation process.

About Effective Embedment

Anchor Bolts (also called Wedge Anchors) get their holding strength from how far down into the Hole
the Anchor Bolt’s Expansion Sleeve presses into the Concrete (called Effective Embedment) and how
forcefully the Expansion Sleeve presses into the Concrete (based on the width of the hole and how
much Torque is applied).

The further down into the Hole you get the Expansion Sleeve, the greater the Effective Embedment
and thus the greater the holding strength of the Anchor Bolt. The hole should be drilled the same width
as the Anchor Bolt with no wobbling. The correct amount of Torque is a range; too little Torque and
the Anchor Bolts hold with less strength, too much Torque and you could damage the Concrete and
lessen the Anchor Bolt’s holding strength.

Note: Some people confuse Effective Embedment with Nominal Embedment, which is how far

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

Final Leveling

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 complete a final leveling on the Lift:

1. Raise your Lift to the first Safety Lock position (the Primary Safety Locks, not the Slack Safety
Locks).

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
when the Safety Locks engage).

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

If you hear the Safety Locks 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, firmly secure the Nuts at the top of each Post.

Installing Accessories

The accessories available for your Lift include:

• Boat Trailer Tongue Platform (TC-3000 model). Sits between the Runways, holds the front

wheel of your boat trailer.

• Gusset Covers. Yellow, Plastic Covers that are installed on top of the Crosstube Gussets.

• Tire Stops. Installed at the Front of the Lift. Hold the Tires of the Vehicle in position. BendPak

recommends chocking the rear Tires, so that the Vehicle stays in place. Included with the Lift.

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

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 soon, try bleeding the Cylinder

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.

the Vehicle

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

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

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

2. Drive a Vehicle onto the Runways.

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. Press the Up button on the Power Unit.

The Runways begin to rise.

4. When the Runways get to the desired height, go up a little bit more, then release the Up button

To maintain your Lift:

• Daily: Keep the Lift clean. Wipe up any spills, clean any dirt.

• Daily: Make a visual inspection of all moving parts and check for damage or excessive wear.

Replace any damaged or worn parts before using the Lift.

⚠ DANGER Do not use the Lift if the Lifting Cables are damaged or extremely worn. If a Vehicle

• 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 on the inside

of the Lift Posts. Use Red Lithium Grease on the Sheave Pins and Bearings.

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

• Monthly: Lubricate the wire rope (Lifting Cables). Use a wire-rope lubricant such as 90-WT gear

oil or ALMASOL® Wire Rope Lubricant.

• Monthly: Check cable connections, bolts, and pins for proper mounting and torque.

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

is 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].

HD-7500 Series Four-Post Lifts 64 P/N 5900174 — Rev. C1 — February 2022

Wire Rope Inspection and Maintenance

Your Lift’s Lifting 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 Lifting 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 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.

HD-7500 Series Four-Post Lifts 66 P/N 5900174 — Rev. C1 — February 2022

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.

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

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.
