Frequently Asked Questions
Question: What kinds of vehicles can I lift on my GP-7 Series lift?
Answer: Cars, light trucks, and SUVs; up to 7,000 lbs (3,175 kg) each.
Q: How long will it take to raise or lower my vehicle?
A: About 45 seconds, depending on what locking position you use.
Q: Does the lift have to be anchored in place?
A: Yes. Two-post lift posts must be anchored. Your lift comes with high-quality, Automotive Lift
Institute-certified Anchor Bolts; use only the Anchor Bolts that came with your lift.
Q: How thick does my concrete have to be?
A: Concrete specifications are: 4.25 inches thick, 3,000 PSI, cured for a minimum of 28 days. Do not
install the lift on cracked or defective concrete. Do not install the lift on asphalt or any surface other
than concrete.
Q: Can I install my lift outside?
A: No. GP-7 Series lifts are approved for indoor installation and use only. Outdoor installation is
prohibited.
Q: Which end is the front of the lift?
A: To determine the front of your lift, drive a vehicle in straight and stop. The front of the vehicle is
where the front of the lift is.
Q: Does it matter if I drive my vehicles in front first or back them in?
A: No. Most people drive their vehicles in front first, which makes it easier to open the vehicle doors.
Other than that, you can drive your vehicles in whichever way you want; the lift works great either way.
Q: How long can I leave a vehicle up?
A: Basically as long as you want, as long as the lift is on a Safety Lock. The locking system is based
on gravity and smart engineering. Once a Safety Lock is engaged, gravity holds the lift in position, so a
loss of power has no effect; your vehicle is going to stay exactly where you left it. Always leave your lift
either on the ground or on a Safety Lock.
Q: How many Safety Lock positions does my lift have?
A: Eleven, spaced every 4 inches.

Components
GP-7 Series lift components include:
•Powerside Post: The Powerside Post holds the Power Unit, the Safety Lock Release Handle,
the Lowering Handle, and the Power Disconnect Switch. You can use either post as the Powerside
Post and the Powerside Post can be on either side of the lift.
•Offside Post: The other post. Identical to the Powerside Post, but when you select a Powerside
Post, the other post automatically becomes the Offside Post.
•Power Unit: Provides hydraulic power to the lift. Connects to a 220 VAC power source. Includes
the button that raises the lift and an Hydraulic Fluid reservoir that must be filled before use.
•Safety Locks: Hold the Lift Arms while they are raised. Multiple Safety Locks let you select the
best Lift Arm height for your needs. Safety Locks use gravity and intelligent engineering to hold the
Lift Arms up once they are on a Safety Lock; even if the lift loses power, the Lift Arms will stay right
where they are if they were left on a Safety Lock. Only leave your GP-7 Series lift on the
ground or on a Safety Lock.
•Safety Lock Release Handle: Releases the lift from its current Safety Lock. To lower a vehicle
from a raised position, hold down the Safety Lock Release Handle and then press down the
Lowering Handle.
•Lowering Handle: Lowers a vehicle from a raised position when used with the Safety Lock
Release Handle.
•Lift Pads: Rubber pads that contact the lifting points of the vehicles you lift. Also included with
your lift are three sets of extensions (short, medium, and tall) that can be used with the Lift Pads.
•Lift Arms: Extendable steel arms that attach to the Lift Heads. Lift Arms hold the Lift Pads; after a
vehicle is moved into place, the Lift Arms are moved so that the rubber pads contact the lifting
points on the vehicle. The Lift Arms are one of the components that actually holds a vehicle up.
•Lift Heads: Sometimes called carriages. Lift Heads move up and down in the posts. They
connect to the Lift Arms, so when the Lift Heads move up, the Lift Arms also move up, thus raising
the vehicle.
•Top Trough: The beam across the top of the lift; it supports the lift’s structure and holds the
Hydraulic Cylinder and the Lifting Cables.
•Trip Stop Tube: Located on the underside of the Top Trough, the Trip Stop Tube stops upward
movement of the lift. If you are raising a vehicle and it hits the Trip Stop Tube, the lift immediately
stops moving up.
•Power Disconnect Switch: Immediately interrupts main electrical power to the lift. Used for
electrical circuit faults, emergency situations, or when lift is undergoing service or maintenance.

⚠WARNING You must wear appropriate protective equipment: leather gloves, steel-toed work
boots, eye protection, back belts, and hearing protection.
Electrical Work
You will need to have a licensed, certified electrician available at some point during the installation.
⚠DANGER All wiring must be performed by a licensed, certified electrician.
The electrician needs to:
•Connect the 220 VAC power source to the Power Unit. This is generally done near the
end of the installation process; do not connect the Power Unit at the same time as you install it.
•Install a Power Disconnect Switch. A Power Disconnect Switch ensures that the equipment
shuts down in the event of an electrical circuit fault or emergency situation. Refer to Install a
Power Disconnect Switch for more information.

•Tape measure, 25 feet or above
•Needle-nose pliers
•Heavy-duty rolling dolly
•Forklift or crane
•Two 12-foot ladders
•Two saw horses
Selecting a Location
When selecting the location for your GP-7 Series lift, consider:
•Architectural plans. Consult the architectural plans for your desired installation location. Make
sure there are no contradictions 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
above .
Refer to Specifications for exact measurements.
•Overhead obstructions. Check for overhead obstructions such as building supports, heaters,
lights, electrical lines, low ceilings, and so on.
•Power. You need a 220 VAC power source available for the lift’s Power Unit.
•Outdoor installations. GP-7 Series lifts are not designed to be installed outdoors. However,
they can be accommodated in certain regions
if optional moisture preventative devices are used.
Email [e-mail] for more information.
•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 GP-7 Series lifts on a level floor (defined as no
more than 3/8 of an inch difference over the installation area). If your floor is not
level, consider making the floor level or using a different location.
•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.
⚠CAUTION BendPak lifts are supplied with installation instructions and concrete anchors that
meet the criteria set by the American National Standard “Automotive Lifts – Safety
Requirements for Construction, Testing, and Validation”, ANSI/ALI ALCTV-2011.
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).
Check your floor for the possibility of it being a post tension slab. In this case, contact the building
architect before drilling. Using ground penetrating radar may help you find the tensioned steel.

GrandPrix (GP-7 Series) Two-Post Lifts 15 P/N 5900209 — August 2018 — Rev. C2
⚠WARNING Cutting through a tensioned cable can result in injury or death. Do not drill into a
post tension slab unless the building architect confirms you are not going to hit
tensioned steel or you have located it using ground penetrating radar. If colored
sheath comes up during drilling, stop drilling immediately.
Anchor Bolt specifications are:
•Length: 6.25 inches
•Diameter: ¾ inch
•Effective embedment depth: 3.25 inches, minimum
•Anchor torque: 110 – 150 foot pounds
⚠WARNING Use the ALI-certified Anchor Bolts that came with your GP-7 Series lift. If you use
components from a different source, you void your warranty and compromise the
safety of everyone who installs or uses the lift.
Clearances

GrandPrix (GP-7 Series) Two-Post Lifts 16 P/N 5900209 — August 2018 — Rev. C2
Unloading and Unpacking
Unload the lift components as close to the installation location as possible.
Once the components are unloaded, they are your responsibility to move around. The lift includes a
number of heavy pieces, so the closer you unload them to the installation location, the better off you
will be.
⚠WARNING Some lift components are very heavy; if handled incorrectly, they can damage
materials like tile, sandstone, and brick. Try to handle the lift components just twice:
once when delivered and once when moved into position. You must have a forklift
or crane to move some of the lift components into position. Use care when moving
them around.
Installation Orientation
To determine the front of your lift, drive a vehicle in straight (do not back it in) and stop. The front of the
lift is where the front of the vehicle is.
The approach is the direction you drive a vehicle onto the lift. Generally the approach is from the rear of
the lift towards the front of the lift.
The orientation of the procedures and drawings in this manual is looking at the lift from the rear,
towards the front, unless specified otherwise. This is the same orientation as shown in the image in the
Components section.
This means that:
•The Powerside Post (which holds the Lowering Handle and the Power Unit) is on the right, the
Offside Post is on the left.
•The
Hydraulic Cylinder end of the Top Trough is installed on the right, above the Power Unit.
•The two angled arms are at the ‘front’ of the lift.
•The two straight arms are at the ‘rear’ of the lift.
Tip You are not required to use this same orientation. Keep in mind, however, that if you
choose to put the Powerside Post on the left, for example, some of the instructions may
need to be reversed.
Putting in Chalk Line Guides
Based on the specifications for your lift, create Chalk Line Guides on the ground for the two posts prior
to moving them into position.
Use the Width Overall value in Specifications
for your lift model to determine where to place the
Chalk Line Guides. The Width Overall value is defined as the distance from the back of one base plate
to the back of the other base plate.

GrandPrix (GP-7 Series) Two-Post Lifts 17 P/N 5900209 — August 2018 — Rev. C2
To add Chalk Line Guides:
1. Decide where you want to locate the lift.
2. Create an alignment chalk line at the desired location.
The alignment chalk line must be longer than the Width Overall setting for your lift model.
3. Create two perpendicular chalk lines at 90° angles to the alignment chalk lines.
The two perpendicular chalk lines must be xdistance from each other, where xis the Width
Overall setting for your lift model.
4. When you move the posts into position, put the corners of the base plates into the corners created
by the Chalk Line Guides.

GrandPrix (GP-7 Series) Two-Post Lifts 18 P/N 5900209 — August 2018 — Rev. C2
Installing the Post Straps
You may want to install the Post Straps on the posts prior to standing them up. It is not required, but if
you install them after standing up the posts, you will need a ladder to reach them.
Important: If you have not already decided which post will be your Powerside Post and which will
be your Offside Post, installing the Post Straps settles the matter: the Post Strap with
the welded plate is the Powerside Post. The other post is the Offside Post.
To install the Post Straps:
1. Bolt the Post Strap
with the welded plate to the Powerside Post.
2. Bolt the other Post Strap (no welded plate) to the Offside Post.

GrandPrix (GP-7 Series) Two-Post Lifts 19 P/N 5900209 — August 2018 — Rev. C2
Installing the Posts
We strongly recommend having multiple people working together to install the posts.
Concrete specifications are:
•Depth: 4.25 inches thick
•PSI: 3,000 PSI, minimum
•Cured: 28 days, minimum
Anchor Bolt specifications are:
•Length: 6.25 inches
•Diameter: ¾ inch
•Effective embedment: 3.25 inches, minimum
•Anchor torque: 110 – 150 foot pounds
⚠WARNING Your Concrete and Anchor Bolts must meet these specifications. Only install your
lift on a Concrete surface. If you install a lift on asphalt or any other surface, or your
Concrete or Anchor bolts do not meet these specifications, it could lead to product
damage, vehicle damage, personal injury, or even loss of life.
BendPak lifts are supplied with installation instructions and concrete fasteners meeting the criteria as
prescribed by the American National Standard “Automotive Lifts – Safety Requirements for
Construction, Testing, and Validation” ANSI/ALI ALCTV-2006.
⚠WARNING Use only the ALI-certified Anchor Bolts that came with your GP-7 Series lift. If you
use components from a different source, you void your warranty and compromise
the safety of everyone who installs or uses the lift.
Lift buyers are responsible for conforming to all regional, structural, and seismic anchoring
requirements specified by any other agencies and/or codes, such as the Uniform Building Code and/or
International Building Code.
Tip Consider
not torqueing the Anchor Bolts into position quite yet. Two reasons: installing
the Top Trough and doing final leveling may be easier if there is a little play in the posts.
To install the posts:
1. Using a forklift, crane, or heavy-duty rolling dolly, move the posts to the Chalk Line Guides you
created earlier.
2. Stand up each post, one at a time, and move the appropriate corners into the corners created by
the Chalk Line Guides.
3. Double check your measurements against the Specifications for your GP-7 Series lift model:
Distance from back of one base plate to back of other base plate: Width Overall value
Distance from inside of one post to inside of other post: Inside Posts value

GrandPrix (GP-7 Series) Two-Post Lifts 20 P/N 5900209 — August 2018 — Rev. C2
4. Using the Base Plates as guides, drill the holes for the Anchor Bolts.
Go in straight; do not let the drill wobble.
Use a carbide bit (conforming to ANSI B212.15-1994).
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.
5. Vacuum each hole clean.
BendPak recommends using a vacuum to get the hole very clean. You can also use a wire brush,
hand pump, or compressed air; just
make sure to thoroughly clean each hole .
Do
not ream the hole. Do not make the hole any wider than the drill bit made it.
Important: The holding strength of an Anchor Bolt is partially based on the how cleanly the
Expansion Sleeve presses against the Concrete. If the hole is dirty, the Expansion
Sleeve does not press as cleanly, which means less holding strength. If the hole is
too wide, the Expansion Sleeve does not press against the Concrete with as much
force, again resulting in less holding strength.
6. Make sure the Washer and Nut are in place, then insert the Anchor Bolt into the hole.
The Expansion Sleeve of the Anchor Bolt may prevent the Anchor Bolt from passing through the
hole in the Base Plate; this is normal. Use a hammer or mallet to get the Expansion Sleeve through
the Base Plate and into the hole.
Even using a hammer or mallet, the Anchor Bolt should only go into the hole part of the way; this is
normal. If the Anchor Bolt goes all the way in with little or no resistance, the hole is too wide.
