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, custom-
made 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
on the Platform, make sure the wheels are
in the Tire Trough, whichever direction you drive it on. For the Vehicle
under the Platform, put it in
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.
Q: How long can I leave a Vehicle raised on the Autostacker?
A: As long as you want,
if it is engaged on a Safety Lock . Autostacker is great for storage in any
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
up to two Access Panels per Autostacker.
Q: How many Lifts can be supported by the Master Power Unit?
A: The Master Power Unit can support up to 12 Autostacker Lifts, although
only one Lift can be
raised and lowered at a time
.

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
must fit on the Autostacker Platform.
•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:
•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 +16 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 +16 +68.5 (third Safety Lock) = 137.5 inches. If you have a 12 foot high
ceiling, you have 144 inches to use, so this combination would fit fine.
The 16 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.
Be especially vigilant the first time
you raise a particular Vehicle!
No one wants to see the roof of their Vehicle
make contact with the ceiling. Use the Emergency Stop button if necessary.

Select a Site
Keep the following in mind when selecting a site for your Autostacker:
•Enough space. Make sure there is adequate space for the Autostacker on all four sides, plus
enough height for the Vehicles you will be lifting. If architectural plans are available, use them to
make sure there is adequate space for your planned layout.
•No overhead obstructions. Make sure the site is free of overhead obstructions such as
heaters, building supports, electrical lines, lights, and so on.
•Concrete specifications. Do not install the lift on cracked or defective Concrete; additionally,a
Anchor Bolts must be at least 6 inches from expansion joints in the concrete or from a wall. Make
sure the concrete is at least 4.25 inches thick, 3,000 psi, and cured for at least 28 days if recently
poured. Make sure the floor is defect-free, dry, and level.
⚠WARNING Do not install your Autostacker on a surface with 3° or more of slope. A 3° degree

anchoring requirements specified by any other agencies or codes, such as the
Uniform Building Code or International Building Code.

Autostacker™ Parking Lift 14 P/N 5900248 — Rev. B — May 2021
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.

Autostacker™ Parking Lift 15 P/N 5900248 — Rev. B — May 2021
Create Chalk Lines Guides
Using Chalk Line Guides makes it easy to position the Autostacker components for installation.
Note: The front of the Autostacker is the end
opposite the Drive-Up Ramp. The Tire Trough is at
the front of the Autostacker and the Drive-Up Ramp is at the back.
To add Chalk Line Guides:
1. Create an Alignment Chalk Line where you want the front of the Autostacker.
Make the Alignment Chalk Line
longer than the Total Width setting for the Autostacker.
2. Create two perpendicular Chalk Lines at 90° angles to the Alignment Chalk Line.
Make the distance between the Left and Right Chalk Line the distance of the
Total Width
setting
for the Autostacker, found in Specifications.
For a Multi-Lift setup, see Multi-Autostacker on Page 49 modified specifications. If you plan
to position the Control Stand at the
Rear of the Lift, use the Total Width (A); do not use the A1
figure.

Autostacker™ Parking Lift 16 P/N 5900248 — Rev. B — May 2021
Position the Autostacker Components
When the Lift components are delivered to the site, try to have them placed near where you will be
installing the unit.
⚠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.
To move the Leg Assemblies into position:
1. Use a Forklift or Shop Crane to move the Leg Assembles into position based on the Chalk Lines.
The Leg Assemblies go on the
inside of the Chalk Lines.
⚠CAUTION Some of the Autostacker components are heavy and can damage materials like tile,
sandstone, and brick if not handled correctly. Move the Leg Assemblies with care
so that you do not cause damage to the surface.
2. Double check to make sure the Leg Assemblies are correctly positioned with the Door-Sentry
car-door protectors on the inside; the Leg Assemblies are
not interchangeable.
Attach the Bottom and Top Connector Tubes
The Bottom Connector Tube holds the bottom of the Autostacker structure together. It is hollow,
allowing the Hydraulic Hoses and the Return Line to be routed through it.
The Top Connector Tube holds the top of the Autostacker structure together. Each end of the Top
Connector Tube connects to the corresponding end of a Platform Arm.
If you have a
Multi-Autostacker setup and plan to position the Control Stand at the Rear of the
Lift, see Multi-Autostacker for modified instructions.
To attach the Bottom and Top Connector Tubes:
1. Move the Bottom Connector Tube into position: on the ground at the front of the Lift.
Important: The Bottom Connector Tube must be oriented so that the smaller gap must be at the
top and the larger gap must be at the bottom.
If you cannot push the Bolts
through the Bottom Connector Tube and into the holes on the base of
the Leg Assembly, it is probably because you have the Bottom
Connector Tube oriented wrong.

Autostacker™ Parking Lift 17 P/N 5900248 — Rev. B — May 2021
Not all components shown. View is front of Autostacker facing towards Rear.
2. Attach one end of the Bottom Connector Tube to a Leg Base using four Bolts from the Parts Box.
3. Use a Forklift or Shop Crane to lift the two Leg Assemblies onto the lowest Safety Lock (which is
roughly 52 inches from the ground).
4. Take three Bolts from the Parts Box, then use them to connect one end of the Top Connector
Tube to the corresponding end of a Platform arm.
Tip The Top Connector Tube is heavy; you need at least two people to connect it (one
person to hold the tube in place, one to connect the tube using the Bolts) or use a
Forklift or Shop Crane to hold it in place while you connect it.
5. Take three more Bolts and use them to connect the other end of the Top Connector Tube to the
corresponding end of a Platform Arm.
Drawing shows how to connect the Top and Bottom Connector Tubes to the Platform Arms. Not
all components shown, some components exaggerated for clarity.

Autostacker™ Parking Lift 18 P/N 5900248 — Rev. B — May 2021
Anchor Bases to the Ground
Each Base has three holes in them for anchoring to the ground, with two holes placed in the front of
each Leg Assembly and one located in the back.
Before you anchor your Autostacker, make sure the Leg Assemblies are correctly aligned. Measure to
verify that the Left and Right Chalk Lines are parallel, then measure diagonally to make sure the two
diagonal measurements are the same; this ensures your layout is correct.
⚠CAUTION Poor alignment can affect how your Autostacker raises and lowers. Re-aligning the
Leg Assemblies
after you anchor them into place is difficult. It is well worth your
time to align your Autostacker correctly before you anchor it into place.
⚠WARNING You must wear OSHA-approved (publication 3151) personal protective equipment
at all times when installing, using, maintaining, or repairing the Autostacker: leather
gloves, steel-toed work boots, eye protection, back belts, and hearing protection
are
mandatory .
Concrete specifications are:
•Depth: 4.25 inches
•PSI: 3,000 psi, minimum
•Cured: 28 days, minimum
Anchor Bolt specifications are:
•Length: 4.75 inches
•Diameter: .75 inch
•Anchor Torque: 85 – 95 pound feet (do not
torque more than 105 or less than 80)
The following drawing shows the locations of the Anchor Bolt holes in the Bases.
To anchor your Autostacker to the ground:
1. Verify the Bases are where you want them; once Anchor Bolts are torqued into position, they are
not easily removed.
2. Using the holes in the Autostacker Bases as guides, drill the holes 4 inches / 101 mm deep.
⚠CAUTION Do not drill all the way through the Concrete; if you punch completely through the
slab, you could compromise the holding strength of the Anchor Bolt.
When drilling, go in straight; do not let the drill wobble.
Use a carbide bit (conforming to the current ANSI B212.15).
The diameter of the drill bit
must be the same as the
diameter of the Anchor Bolt. So if you are using a ¾ inch
diameter Anchor Bolt, for example, use a ¾ inch diameter drill
bit.

3. Use a wire brush or Vacuum to thoroughly clean each hole.
You can also use a hand pump or compressed air. Make sure
to thoroughly clean the holes.
Do
not ream the hole. Do not make the hole any wider than
the drill bit made it.
4. Make sure the Washer and Nut are in place, then insert the Anchor Bolt into the hole.
5. Hammer or mallet the Wedge Anchor the rest of the way down into the hole.
Stop hammering when the Washer is snug against the Base.
Use a hammer or mallet to get the Expansion Sleeve through
the Base and down into the hole.
Even using a hammer or mallet, the Anchor Bolt should only
go into the hole part of the way; this is normal. If the Anchor
Bolt goes all the way in with little or no resistance, the hole is
too wide.
Once past the hole in the Base, the Anchor Bolt eventually
stops going down into the hole as the Expansion Sleeve
contacts the sides of the hole; this is normal.
6. Wrench each Nut
clockwise to the recommended installation torque, 85 – 95 pound feet, using a
Torque Wrench.
Wrenching the Nut forces the wedge up, pushing out the
Expansion Sleeve and pressing it tightly against the Concrete.
Important: Do
not use an impact wrench to torque the
Anchor Bolts.

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; these will be
attached later when you are ready to attach to the Top of the Console.
