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). Mounts between the Runways and supports

the front jack of your boat trailer.

• Power Side Runway. The Runway next to the Power Post. The Power Side Runway has Lifting

Cables and the Hydraulic Cylinder on its underside. You

• 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).

• 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 farther 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

The Lift supports less weight than its rated capacity when the Vehicle’s wheelbase is shorter; this is due to
the wheels moving closer to the middle of the Runways, where there is less support. For example, the

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) and

Boats too using the TC-3000 Trailer Tongue Assembly.

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

A: About 45 to 55 seconds. Lowering times are longer if there is no weight on the Lift.

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.

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.

that the vehicle cannot roll backward off the Lift.

Q: Will the Lifting Cables really hold my Vehicle?

A: Yes. Each Lifting Cable is 0.4 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.

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-toed 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-75BXT Series Four-Post Lifts 14 P/N 5900282 — Rev. A — February 2023

Planning for Electrical Work

A licensed Electrician will be required at some point during the installation.

⚠ DANGER All electrical work

Notify your Electrician in advance so that they arrive prepared with appropriate components for
connecting to the facility 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 electrical 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 protected by
an appropriate circuit breaker.

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, or when
equipment is undergoing service or maintenance. Install the disconnect within sight and reach of
the Lift operator.

• Install a Thermal Disconnect Switch. The thermal disconnect 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 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, to a maximum of 0.5 in. / 13 mm, 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. Verify 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.

WARNING Always leave the Runways either fully

Safety Locks. When you engage the
Safety Locks at a desired height,
check to make sure that all four
Safety Locks are engaged at the
same height.

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 break (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 two Runways:

• Power Side 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 Power Side 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 Power Side Runway by looking under the two Runways (only the Power Side 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 Power Side 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 Power Side Runway does.

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. Use clean, dry air. 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. New does not necessarily mean 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.

Hydraulic System Warnings

Before applying power to the Hydraulic System note the following Warnings:

WARNING Failure to observe these warnings can result in serious personal injury including, in

⚠

rare cases, death.

⚠ WARNING The Hydraulic hoses and connections must be inspected before any attempt to

raise a Vehicle is made.

⚠ WARNING

Verify all

plugs on the Power Unit, the Cylinders and anywhere else in the Hydraulic System
are tightened.

Hydraulic Hose connections and fittings, including unused auxiliary port

⚠ WARNING The Power Unit is a Hydraulic Pump capable of developing pressures in excess of

5,000 psi (345 BAR). A pressure relief valve is used to set the pressure at the
desired level. Tampering with, adjusting, modifying, or removing the relief valve is
extremely dangerous and is not recommended. Only trained Hydraulics technicians
should adjust the relief valve, using calibrated hydraulic pressure gauges to assure
the proper pressure setting is achieved.

⚠ WARNING Changes to the output pressure may render the Power Unit incompatible with

pressure limitations on other components in the hydraulic circuit. This may cause
catastrophic failure of those components, and could result in property damage,
serious personal injury or death.

⚠ WARNING The Hydraulic System can contain high pressure which, if suddenly released, can

cause serious injury or death.

⚠ WARNING Do not attempt to connect or disconnect Hydraulic Hoses while the equipment is

loaded or while a Vehicle is on the Lift or the Hydraulic System is under pressure.

⚠ WARNING Keep bare hands away from Hydraulic Fluid; always wear gloves when handling

Hydraulic Fluid, Cylinders or Hydraulic Hoses.

⚠ WARNING When handling Hydraulic Fluid, always observe the safety instructions from the

manufacturer.

⚠ WARNING Always promptly clean any Hydraulic Fluid spills. If a leak in the system is the

source of the spill, lockout the Lift to prevent use until the Hydraulic System is
repaired.

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

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 fluid.
Several power units are available. The fluid capacity of several common units are detailed below.
Always refer to your actual unit for the exact capacity.

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-75BXT Series Four-Post Lifts 41 P/N 5900282 — Rev. A — February 2023

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.

Install 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 Power Side 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. 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:

Ferrules can only be tightened once

the Ferrule is compressed; the Ferrule may not be reused after this compression.

. When you tighten the Nut on the Threads,

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.

HD-75BXT Series Four-Post Lifts 43 P/N 5900282 — Rev. A — February 2023

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 farther 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.

Install 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 figure details the Pushbutton Air Valve and its connections.

HD-75BXT Series Four-Post Lifts 44 P/N 5900282 — Rev. A — February 2023

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.

Install 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 ¼-inchTubing

⚠ CAUTION Make sure to route the Tubing pieces on the

Crosstubes through the Steel Tubes welded 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 damaged, 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 repair the Air Lines.

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 achieve their holding strength from the depth at which the Anchor Bolt’s Expansion
Sleeve presses into the Concrete (Effective Embedment) and how forcefully the Expansion Sleeve
presses into the Concrete (based on the width of the hole and Torque applied).

The deeper the Expansion Sleeve, the greater the Effective Embedment, thus the greater the holding
strength of the Anchor Bolt. The hole should be drilled at the same diameter as the Anchor Bolt with
no wobbling. The correct amount of Torque is a small range; exceeding the recommended Torque
value may damage the concrete and reduce the Anchor Bolt’s holding strength.

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.

Install Accessories

The accessories available for your Lift include:

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

front Jack of your boat trailer.

HD-75BXT Series Four-Post Lifts 56 P/N 5900282 — Rev. A — February 2023

Tire Stops

Tire Stops are attached on the Front of the Lift. They prevent the tires of the Vehicle on the Lift from
trvelling too far forward.

To install the Tire Stops:

1. Locate the two Tire Stops, two Tire Stop Pins, and four Rotor Clips.

2. Put one Tire Stop in position between the Tubes attached to the Runway, then put the Tire Stop
Pin all the way through the Tire Stop and the Tubes.

3. Secure the Tire Stop with Rotor Clips on each end of the Tire Stop Pin.

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

Ramps

Your Lift comes with two steel Ramps, for driving Vehicles onto the Runways.

To install the Ramps:

1. Find the required components: two Ramps, two Ramp Pins, and four 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 heavy and awkward, so you may want to consider having two people

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.

HD-75BXT Series Four-Post Lifts 57 P/N 5900282 — Rev. A — February 2023

Anti-Slip Tape

Anti-Slip Tape is designed to increase friction between the metal surface of the Lift Ramps and
Vehicles or personnel on the Lift. The Anti-Slip Tape is provided in a single roll measuring 6 in. x 24 ft.
(152 mm x 7.3 m). BendPak suggests cutting the Tape into four equal lengths 72 in. (1,829 mm) long.

IMPORTANT! Surface preparation is critical. If the runway is in poor condition with gouges, holes,

or jagged edges, the Anti-Slip Tape will not adhere. Lift Runways must be clean,
dry, and smooth. No grease or oil should be on the Ramp surface.

To apply the Anti-Slip Tape:

1. Clean the runway. Use a broom or brush to remove loose dirt and debris from the runway.

2. Thoroughly wash, rinse, and dry the runway using a mild solution of soap and clean water to
remove any oils, grease, and water-soluble contamination. Dry the runway with a clean cloth and
allow to air dry.

3. Cut the Anti-Slip Tape into four equal pieces. Suggested length is 72 in. (1,829 mm).

4. Verify the Runway is dry and clean. It is critical for maximum adhesion of the Anti-Slip Tape that
the runway be dry, free of dirt, oils, and grease.

5. Measure and mark the runways with pencil guidelines to outline the tape installation area on the
ramp. Refer to the figure on the next page for a suggested layout of the Anti-Slip Tape.

IMPORTANT! Do not install this Tape directly on the edge of a Runway. Stay at

least 1 in. (25 mm) away from edges. Do not attempt to bend the
Tape over an edge.

6. Wash your hands. The Anti-Slip Tape’s adhesive side is protected by a paper or plastic film. You
will remove this film a few inches at a time to apply the Tape to the Runway.

IMPORTANT! Handle the tape by its edges. Minimize contact between the

adhesive and your hands. The oils from your hands will reduce the
adhesive’s long-term effectiveness.

IMPORTANT! BendPak recommends two people work together to install the Tape.

One person removes the backing and applies the Tape to the
Runway while the second holds the Tape in place over the
guidelines marked on the Runway.

7. Lay one piece of the Anti-Slip Tape on the runway and peel back about 2 inches (50 mm) of the
protective film. Apply the adhesive side to the Runway inside the guidelines you created in step 5.

8. Slowly remove the film as you press the exposed Tape’s adhesive side into the Runway. Work
slowly and apply 2 to 5 inches at a time to stay within your guidelines.

9. After applying the Tape use a heavy rubber roller to press the Tape onto the Runway and to
ensure firm contact with the adhesive.

10. Apply the Anti-Slip Tape to the remaining area of the Lift’s runways similar to the figure on the
next page.

Caster Kit

The Caster Kit is an accessory option (purchased separately) and includes four assemblies, each of
which installs under one of the Lift’s four Posts. When the Lift is raised by the Caster Kit assemblies,
you can move it to the desired location.

Important: When the move is complete, remove the Caster Kit assemblies. Do not leave the

Caster Assemblies in place while operating the Lift.

HD-75BXT Series Four-Post Lifts 59 P/N 5900282 — Rev. A — February 2023

To move your Lift with the Caster Kit:

1. Raise the Lift to the first Safety Lock and engage it.

2. Locate the components of the four Caster Kit assemblies.

3. Using the supplied hardware, bolt the four Casters to the four holes in the four Caster Kit Shafts.

4. Take one Shaft and put the open end around the Post, with the Shaft on the inside of the Lift.

The Cradle of the Shaft needs to be directly below the Crosstube.

5. Put the Pin through the holes in the Caster Kit assembly and the Post.

6. Put the Cotter Pin into place on the end of the Pin.

7. Repeat Steps 4 through 6 for the other three Caster Kit Assemblies.

8. Lower the Lift down to the ground.

Make sure the Crosstubes are going into all four Cradles on all four Caster Kit Shafts; this is what
pushes the Bases of the Posts off the ground so that you can move it.

9. Move the Lift to the desired location.

10. Raise the Lift to a locking position and engage it there.

11. Take off all four Caster Kit assemblies.

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 time consuming to raise a
Vehicle and then realize you left something inside.

Maintenance

⚠ DANGER Before performing maintenance on your Lift, verify it is disconnected from power.

To maintain your Lift:

• Daily: Keep the Lift clean. Wipe up any spills, remove 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: Verify 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 any that 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 verify they are properly torqued. If they are loose,

tighten them.

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 for repair or replacement.

⚠ 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-75BXT Series Four-Post Lifts 68 P/N 5900282 — Rev. A — February 2023

Wire Rope Inspection and Maintenance

The Lifting Cables, are wire rope and 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.

Bleeding the Hydraulic System

The Hydraulic System 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 verify 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.
