Introduction

Autostacker is available in two versions:

• A6S. Parking Lift that allows you to make a parking spot that holds just one Vehicle into a parking

spot that holds two Vehicles, lifting vehicles up to 6,000 lbs (2,722 kg).

• A6W. Wide version of the A6S, with an extra 8 inches of width for your Vehicles.

Autostacker is also available in a
single Master Power Unit.

Unless specifically stated, the setup for each Autostacker in a Multi-Lift configuration follows the same
installation process as a single Autostacker. See Multi-Autostacker towards the end of this manual
for those modified procedures. After you have completed those modified procedures, continue the
remainder of the installation as you would with a single Autostacker; see the Installation Checklist

Frequently Asked Questions

Question: What kinds of Vehicles is Autostacker designed for?

Answer: Autostacker is designed for cars, light trucks, and SUVs.

Q: Why is the Platform angled?

A: The angled Platform allows low-profile Vehicles to drive directly onto the Platform without scraping.

Q: How high does my garage ceiling have to be to use Autostacker?

A: Autostacker works great with ceilings as low as 10 feet. However, the height of the ceiling does

impact what cars you can park on the Lift. Refer to Will My Car Fit? for complete information.

Q: Can I put the Console on either side of the Autostacker?

A: Yes. The included Hydraulic Hoses are long enough to support the Console being up to 30 inches

away on either side. If you want, you could go to your local hydraulics shop and get longer, custom­made Hydraulic Hoses that give you greater latitude for where you put your Console.

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

A: No, Autostacker works great either way. For the Vehicle

in the Tire Trough, whichever direction you drive it on. For the Vehicle
whichever direction makes it easier to open the doors. Note that it is not required that you drive your
Vehicle all the way underneath the Platform; for some Vehicles, opening the doors is easier if you only
drive part way in.

condition, long or short-term.

Q: How many Safety Locks does my Lift have?

A: 5. See Raising a Vehicle for the different locking heights.

Q: Can I change the oil on the Vehicle raised on the Autostacker?

A: Yes; the optional Access Panel gives you access to the underside of the Vehicle that is raised,

making your parking lift into a service lift as well. Each Access Panel works in place of three Platform
sections and you can install

Will My Cars Fit?

Autostacker accommodates a wide variety of cars, light trucks, and SUVs. This section describes how
to get wider, longer, and taller Vehicles onto your Autostacker.

Width

Considerations for Vehicle width include:

• Platform width. The width from the outside of the left tires to the outside of the right tires cannot
exceed the width of the Platform. The tires

• Mirrors. Mirrors and other accessories may mean that some parts of a Vehicle are much wider
than the tires of the Vehicle. This is generally not a problem on a raised Vehicle, but should be
taken into consideration for Vehicles being parked under the Autostacker.

• Doors. Opening car doors makes the Vehicle wider while they are open. If opening Vehicle doors
is an issue, try driving in the Vehicle in the other direction. Autostacker Legs have Door-sentry car
door protectors, which limit problems if a door does contact an Autostacker Leg.

Length

Considerations for Vehicle length include:

must

fit on the Autostacker Platform.

• Vehicle wheelbase. Vehicles that get raised on the Platform must have one set of wheels in the
Tire Trough and the other set on the Platform itself.

• Overhang. If a Vehicle’s wheelbase fits on the Platform, then any overhanging parts of the Vehicle
outside the wheelbase are not an issue.

Height

Considerations for Vehicle height include:

• Ceiling height. The height of the ceiling determines how much space you have for the two
Vehicles. If you want to park both a tall Vehicle on and under your Autostacker, your ceiling needs
to be higher than if you want to park two low-slung Vehicles.

• Formula. There’s a formula for figuring out how high a ceiling you need.

Height of Vehicle on Platform + 6 inches + Safety Lock height

For example: Say you have a 2017 Camaro and a 2017 Toyota Camry. The Camry is 58 inches
high, the Camaro is 53 inches. If you want the Camry under the Platform and the Camaro on it, the
formula would be 53 + 6 + 68.5 (third Safety Lock) = 127.5 inches. If you have a 12 foot high
ceiling, you have 144 inches to use, so this combination would fit fine.

The 6 inch figure includes the height of the Platform plus the height needed to raise the Lift off of
the Safety Lock. Note this figure is a rough estimate, for calculation purposes only.

⚠ CAUTION We recommend double checking your ceiling and Vehicle heights before raising a

Vehicle on the Autostacker Platform.

Create a Floor Plan

You need to plan out, in advance, where the Autostacker is going to go. You should consider:

• Access. The Autostacker is a Parking Lift, so be sure you can drive Vehicles onto it.

• Side clearance. Consider whether or not you want enough room on the sides for people to walk
around the Autostacker.

• Front clearance. Vehicles parked on the Platform may extend over the front.

• Rear clearance. You are not required to park a Vehicle all the way underneath the Platform.
Depending on the Vehicle, it may be easier to get in to and out of the Vehicle if you only go
partway under the Platform, as shown below.

• Console. The Console must be located near the Autostacker; the Hydraulic Hoses that come with
the Autostacker are optimized for up to 30 inches between the Autostacker and the Console.

• Operator. The operator at the Console must have a full, unobstructed view of the Autostacker.

• Power. The Console must also be positioned near the power source.

⚠ CAUTION Some of the Autostacker components are heavy and can damage materials like tile,

sandstone, and brick if not handled correctly. You must have a Forklift or Shop
Crane to move them into position. Try to handle the Autostacker components only
twice: once when delivered and once when moved into position.

Autostacker components include:

• Two Leg Assemblies: Each Leg Assembly includes a Base, Leg, Hydraulic Cylinder, and
Platform Arm.

• Bottom Connector Tube: Connects to the Leg Assembly Bases. The Hydraulic Hoses and the
Return Line are routed through the hollow Bottom Connector Tube.

• Top Connector Tube: Connects to the Leg Assembly Platform Arms. Also attaches to the Tire
Trough.

• Tire Trough: A single piece with a lowered portion (to hold the Vehicle’s tires from moving, which
holds the Vehicle in place). Attaches to the Top Connector Tube and the first Platform section at
the front of the Autostacker.

• Platform: Made up of galvanized steel sections that are bolted together.

• Ramp: A single piece, angled for easy drive-up.

Assemble the Console and Attach the Power Unit

The Console can go on either side of the front of the Lift.

Tip If you want to place the Console further than 30 inches from your Autostacker, you will

need to get Hydraulic Hoses that are long enough to reach the Lift from where you want
to put the Console. These should be relatively easy to obtain from the local hydraulics
shop; you will also need a longer Return Line.

The following drawing shows the components that make up the Console.

To assemble the Console and attach the Power Unit:

1. Select a site for the Console that permits operators to have a full, unobstructed view of the Lift.

2. Arrange all of the Console components as shown below.

Do not attach the Nuts at the top of the sides or the Back at this point;

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.

Autostacker™ Parking Lift 23 P/N 5900248 — Rev. B1 — May 2022

About Thread Sealants

Your Autostacker comes with a 4 ounce Bottle of Liquid Thread Sealant.

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

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.

Theadlocker

; 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

Not all components are shown.

Autostacker™ Parking Lift 25 P/N 5900248 — Rev. B1 — May 2022

To connect the Hydraulic Hoses:

1. Locate the two Hydraulic Hoses that come with your Lift.

The two Hydraulic Hoses are the same length; it does not matter which Hydraulic Hose goes to
which Hydraulic Cylinder on the Lift.

2. Starting near the Console, route both Hydraulic Hoses through the Bottom Connector Tube and
pull it out at the Hydraulic Cylinder that is furthest away from the Console.

One Hydraulic Hose goes to the Hydraulic Cylinder that is closest to the Console, while the other
Hydraulic Hose goes to the Hydraulic Cylinder that is furthest away from the Console.

Leave enough of the Hydraulic Hose on the Console end to allow the Hydraulic Hoses to be
connected to the Power Unit up through one of the openings at the bottom of the Console.

Pull out enough of the Hydraulic Hose to reach the Bulkhead Fittings when it is time to put all of the
components together.

3. On each Hydraulic Cylinder, install Velocity Fuses in the Ports near the bottom of each Hydraulic
Cylinder. Finger tighten the connection.

Use Thread Sealant on NPT Threads only.

Refer to About Velocity Fuses for more information.

4. For both Hydraulic Cylinders, remove one Nut from the Bulkhead Fitting, put the Bulkhead Fitting
into the Connector Weldment, put the Nut you just removed back onto the Bulkhead Fitting, and
finger tighten both Nuts around the Connector Weldment.

5. For both Hydraulic Cylinders, connect the Hydraulic Line Assembly to the top end of the Bulkhead
Fitting and the other end to the top end of the Velocity Fuse. Finger tighten the connections.

6. For both Hydraulic Cylinders, connect the Hydraulic Hose to the bottom end of the Bulkhead
Fitting. Finger tighten the connections.

7. Attach two Elbow Fittings to both Hydraulic Pressure Ports on the Power Unit.

There are two Hydraulic Pressure Ports on a Power Unit, in varying locations (depending on the
Power Unit you have). Refer to Connect the Power Unit to identify your Power Unit layout.

8. Route the two Hydraulic Hoses, one at a time, through an opening along the bottom of the
Console and up to one of the Elbow Fittings, then connect them. It does not matter which
Hydraulic Hose goes to which Hydraulic Pressure Port.

Coil any additional Hydraulic Hose length inside the Console.

9. Once all connections have been made, use the appropriate tools to fully tighten all of the
finger-tightened connections.

Working with Return Lines and Compression Fittings

Autostacker uses Return Lines made of a roll of ¼ inch, polyethylene Tubing (also called Poly-Flo®)
that is used with Compression Fittings to attach to the Air Cylinders and the Return Line Connectors.

The components involved with Compression Fittings include:

• ¼ inch, black, polyethylene Tubing. The Return Lines require several lengths of tubing to
make the necessary connections back to the Console.

• Elbow Compression Fittings (also called a 90° fitting). The Return Lines use Elbow Fittings to
attach to each Hydraulic Cylinder and one that connects to the Console.

• Tee Compression Fitting. The two Return Lines hooked up to the Hydraulic Cylinders connect
to a Tee Compression Fitting that goes back to the Power Unit.

• Nuts, Ferrules, Rods, and Threads. Each connector on Elbow and Tee Compression
Fittings have a Nut, Ferrule, Rod, and Threads. 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 there are no leaks.

Connect the Return Line

The Return Line takes extra Hydraulic Fluid from the Hydraulic Cylinders and returns it to the Power
Unit’s Hydraulic Fluid Reservoir; it also allows air to move in and out of the Hydraulic Cylinders.

One end of the Return Line connects to the Power Unit (where it goes into the Reservoir). There are
two other ends; they attach to Return Line Connectors, which are near the top of each Hydraulic
Cylinder.

The Return Line comes as one long roll of tubing; you need to cut it into sections of the right length.

If you have a Multi-Lift setup, this procedure will be slightly different for you

Test the Autostacker

Before putting your Autostacker into normal operation, we recommend breaking it in by raising and
lowering it a few times. This will help you get a feel for how to operate it and also helps to get any
residual air out of the hydraulic system.

Tip Residual air in the hydraulic system can cause the Autostacker to shake, move

erratically, or squeak; this is normal. If it happens to you, do not worry; it will go away
quickly as the Autostacker is self-bleeding.

Neither the Platform nor the Drive-On Ramp need to be installed to test the lift. You also do not need
weight on the Lift.

Note: The Autostacker lowers a little slower with no weight on it.

To test your Autostacker:

1. Check the area around and above the Autostacker for obstructions.

Move them if you find any.

2. Insert the key and move it to the On position.

3. Press and hold Up.

4. Before reaching the first Safety Lock, release Up.

5. Press and hold Down.

6. When the Autostacker gets to the ground, it stops lowering; release Down.

7. Wait for one minute.

⚠ WARNING The Power Unit is not a constant duty motor; it cannot be run continuously.

8. Repeat the process, this time raising the Autostacker just past the first Safety Lock.

You can tell when the Autostacker passes a Safety Lock: when the Lock Hood goes past a Lock
Block, it hits the base and makes an audible click. Refer to About Safety Locks for more
information.

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

If the Autostacker is shaking, moving erratically, or squeaking, repeat the procedure one more
time, raising the Autostacker to the second Safety Lock.

It is normal for the Autostacker to shake, move erratically, or squeak when you first get it. Using it a
few times almost always fixes those issues.

If your Autostacker continues to have problems well past the break-in period, refer to

Troubleshooting for additional information.

Lubricate the Lift

The Autostacker has eight Lubrication Points, four on each Leg Assembly. You must grease the
Threaded Grease Fitting (P/N 5550025) at the Lubrication Points before you start normal operation of
your Autostacker. Refer to Maintenance for more information.

Tip Autostacker recommends using white lithium grease, or similar, and a grease gun

with an appropriate tip (a Lube-Link™, for example) when lubricating your lift.

The Threaded Grease Fittings / Lubrication Points on each Leg Assembly are:

Final Checklist

Make sure these things have been done before using your Lift:

• Review the Installation Checklist to make sure all steps have been performed.

• Make sure the Power Unit is getting power from the power source.

• Check the Power Unit’s Hydraulic Fluid reservoir; it must be full of approved Hydraulic Fluid or
automatic transmission fluid. You can harm the motor by running it without enough fluid.

• Check the Hydraulic System for leaks.

• Check to see that all Anchor Bolts are properly tightened.

• Make sure that all Safety Locks are cleared and free.

• Make sure a copy of the Installation and Operation Manual is left with the equipment, so that it is
available to all operators, and make sure all labels are visible.

• Raise the Autostacker to each of the six Safety Locks and measure the space between the ground
and the bottom of the Drive-Up Ramp. Check these values against the values shown in Raising a

Vehicle. These are the actual values that you should use to determine what Vehicles you want to

put where.

• Perform an operational test of the Lift with a typical Vehicle.

During the operational test, observe all operating components and check for proper installation and
operation. Do not raise any additional vehicles until a thorough operational check has been
performed with a typical Vehicle.

If the Autostacker fails the operational test, take it out of service, then consult Troubleshooting
to begin addressing the problem.

About Velocity Fuses

Velocity Fuses are a safety feature. They stop hydraulic flow in the event of a Hydraulic Hose failure.

Every Autostacker comes with one Velocity Fuse per Hydraulic Cylinder.

When the Platform is being raised, Hydraulic Fluid moves under pressure from the Power Unit to the
Hydraulic Cylinder, which uses this force to raise the Platform. When the Platform is being lowered,
Hydraulic Fluid moves back from the Hydraulic Cylinder to the Power Unit.

The Velocity Fuse monitors the flow of Hydraulic Fluid
Velocity Fuse shows the flow direction it is monitoring. The other direction is not monitored.

Most of the time, the force of the flow back to the Power Unit is beneath the trigger value of the
Velocity Fuse. If, however, the Hydraulic Hose were to be accidentally cut, for example, the force of the
flow back towards the Power Unit would increase significantly. If the force of the flow goes above the
trigger value of the Velocity Fuse, the Velocity Fuse kicks in and blocks the flow thus stopping descent.

.

To install the Return Line:

1. Attach an Elbow Fitting to the Hydraulic Return Port on the Power Unit.

⚠ CAUTION The Hydraulic Return Ports are commonly labeled T1/T2, CV1/CV2, or G; the

Hydraulic Pressure Ports are almost always labeled P1/P2. Do not accidentally
attach a Hydraulic Hose to the Return Line Port or vice versa. Your Autostacker will

not

work right unless the Return Line and Hydraulic Hoses are attached to the

correct Ports.

2. Attach an Elbow Fitting near the top of each Hydraulic Cylinder.

3. Attach a Tee Fitting near the bottom of each Cylinder.

The Hydraulic Cylinder furthest from the Power Unit (on the last Lift in your Multi-Lift configuration)
does not need a Tee Fitting, as shown in the drawing.

4. Find the Return Line Tubing and measure the lengths of the segments you need, then cut the
appropriate lengths.

5. Connect the various pieces of Tubing to the Elbow Fittings and Tee Fittings on each Lift in your
setup, as shown in the drawing above.

See Working with Return Lines and Compression Fittings for more information.

6. If there are no further Lifts to connect to, connect a final Return Line to the top of the last Hydraulic
Cylinder, and the other end to the Tee Fitting on the first Hydraulic Cylinder (on the same Lift).

Make sure the final segment is long enough to reach from the Tee Fitting, through the Bottom
Connector Tube, and to the top of the last Hydraulic Cylinder.

Multi-Autostacker Maintenance

In addition to the steps outlined in the maintenance section for a single-Lift configuration, there are a
few extra things to look for:

• Daily. Make sure the electrical connections are covered and protected from all sources of
moisture.

• Monthly. Make sure the Master Power Unit and Reservoir are contaminant-free; if there is debris
in the system, the Lift(s) may not work correctly. Use air or a wire brush to remove debris from the
Power Unit components (for example: the Lowering Valve, which is a component inside the Master
Power Unit).

• Monthly. Raise each Lift to the top Safety Lock and then lower back to the ground, to make sure
the Lifts are working normally.

• Every two months. Check the Control Stand Bolts to make sure they are tight; secure any
loose Bolts.

• Yearly. Have a licensed, certified Electrician come to your site to check all electrical connections.
