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 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. Anchor Bolts must be at least 6 inches from
cracks, expansion seams, or other inconsistencies in the Concrete. Do not install the Lift on
asphalt or any surface other than Concrete.
Q: Can I install my Lift outside?
A: No. GrandPrix 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: How long can I leave a Vehicle up?
A: Basically as long as you want, as long as the Lift is engaged on a Safety Lock. 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 where you left it. Always leave your Lift either fully lowered or engaged on a Safety
Lock.
Q: How many Safety Lock positions does my Lift have?
A: Eleven, spaced every 4 inches / 101.5 mm.
Q: Does the Lift have a Front and Rear?
A: Yes and no. Because you can drive onto a two-post Lift from either opening, there is technically
no Front and Rear. However, most garages have an Approach side and a Wall side, so in that
case, the Wall side is the Front and the Approach side is the Rear.
Q: How do I know where to put the Adapters when I want to raise a Vehicle?
A: The Vehicle needs to be balanced, so you must put the Adapters (sometimes called Pads) so that
they contact the manufacturer’s recommended Lifting Points.
If you do not know where the
manufacturer’s recommended Lifting Points are on a Vehicle, you must find out
before you raise it
. Your Lift came with books that will help: Vehicle Lifting Points for Frame
Engaging Lifts shows the Lifting Points for hundreds of Vehicles. Lifting It Right includes
information about how to raise Vehicles correctly.

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. The Powerside Post must go under the
Cylinder end of the Top Trough.
•Offside Post. The other Post. The Offside Post goes under the Cables end of the Top Trough.
•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 fully
lowered or engaged on a Safety Lock.
•Slack Safety Locks. The Lift has a backup set of safety locks called the Slack Safeties. During
normal operation, the Lifting Cables hold back the Slack Safeties so that they do not engage. If,
however, a Lifting Cable were to break (which rarely happens!), the Slack Safety for the Lifting
Cable that broke would kick in immediately.
•Safety Lock Release Handle. Releases the Lift from its current Safety Lock. Used as part of
the lowering process.
•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 raise. Also included
with your Lift are three sets of extensions (short, medium, 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 (and anything on them)
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.
•Thermal Disconnect Switch. Overload device that makes sure the equipment shuts down if
there is an overload or an overheated motor. The Lift’s motor has no thermal overload protection.

The installation process includes multiple steps. Perform them in the order listed.
Safety Rules
When installing the Lift, 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 crane, to raise 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, when needed. Stay clear of moving parts.
⚠WARNING You must wear appropriate protective equipment: leather gloves, non-skid steel-
toed work boots, eye protection, back belts, and hearing protection.
Plan Ahead for Electrical Work
You will need to have a licensed, certified Electrician available at some point during the installation. All
of the tasks listed below must be performed by an Electrician.
⚠DANGER All wiring must be performed by a licensed, certified Electrician. If someone who is
not a certified Electrician attempts these tasks, they could damage the Lift or be
electrocuted, resulting in serious injury or even death.
The Electrician needs to:
•Wire 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.
•Wire the Microswitch to the Power Unit. This is generally done at the same time as the
Electrician wires the power source to the Power Unit, as the Microswitch wiring goes between the
incoming power source and the Electrical Box on the Power Unit.
•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.
•Install a Thermal Disconnect Switch. A Thermal Disconnect Switch ensures that the
equipment shuts down in the event of an overload or an overheated motor. Refer to Install a
Thermal Disconnect Switch for more information.
The Electrician is responsible for providing:
•an appropriate power cable and plug for connecting to the power source
(wiring to connect the Microswitch to the Power Unit is included)
•a Power Disconnect Switch
•a Thermal Disconnect Switch
Additional information is supplied in the sections describing these tasks.

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. GrandPrix Lifts are approved for indoor installation and use only.
Outdoor installation is prohibited .
•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 GrandPrix 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. Anchor Bolts
must be at least 6 in from cracks, expansion seams, or other inconsistencies in the Concrete.
Make sure the concrete is at least 4.25 inches thick, 3,000 PSI, and cured for at least 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.

Clearances

GrandPrix Two-Post Lifts 15 P/N 5900209 — Rev. D3 — Feb. 2020
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 and in the drawing below.
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 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.
The following drawing shows how to orient the Powerside and the Offside Posts.
Not necessarily to scale. Not all components shown.

GrandPrix Two-Post Lifts 16 P/N 5900209 — Rev. D3 — Feb. 2020
To identify the Powerside Post and the Offside Post, look at the tops of the Lift Heads in each of the
Posts:
•Powerside Post. The Lift Head with widely spaced holes is the Powerside Post. The Powerside
Post must go under the Cylinder End of the Top Trough.
•Offside Post. The Lift Head with the narrowly spaced holes must be the Offside Post. The
Offside Post must go under the Cable End of the Top Trough.
Important: You
must orient the Powerside and Offside Posts this way. If they are set up wrong,
the Lift will not work correctly.
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.

GrandPrix Two-Post Lifts 17 P/N 5900209 — Rev. D3 — Feb. 2020
Checking the Safety Spring
Before standing up the Posts of the Lift, check to make sure the Safety Spring has not been knocked
out of place during transport.
The Safety Spring should be in position, as shown below.
Post removed for clarity. Not all components shown.
To determine whether or not the Safety Spring is in place, either slide the Lift Head up so that it comes
out of the Post enough so that you can see the Safety Spring and verify it is in place or take a flashlight
and shine it down through the Post to visually verify that the Safety Spring is in place.
If the Safety Spring has come loose during transport:
1. Slide the Lift Heads up until the Safety Spring is accessible.
2. Reconnect the Safety Spring in the location shown above.
3. Slide the Lift Heads back down.
Because the Lifting Cables are not in place, the Slack Safeties will engage when you move the Lift
Head back down (they are prevented from engaging during normal operation).
Manually hold the Slack Safeties so that they cannot engage as you lower the Lift Head.
Important: You
must disengage the Slack Safeties before proceeding with the installation.

GrandPrix Two-Post Lifts 18 P/N 5900209 — Rev. D3 — Feb. 2020
Installing the Post Straps
You may want to install the Post Straps on their 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: The Post Strap with the
welded plate goes on the Powerside Post. The Post Strap
without the welded plate goes on 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 Two-Post Lifts 19 P/N 5900209 — Rev. D3 — Feb. 2020
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.
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 Two-Post Lifts 20 P/N 5900209 — Rev. D3 — Feb. 2020
About Embedment
Anchor Bolts (also called Wedge Anchors) get their holding strength from how far down into the Hole
the Anchor Bolt is installed (called embedment) and how forcefully the Expansion Sleeve presses into
the Concrete (based on how much torque is applied).
To get enough embedment, you have to understand Effective Embedment, which means the location
in the Hole where the Expansion Sleeve presses into the Concrete. This is where the Anchor Bolts
create holding strength; the further down into the Hole, the greater the holding strength.
(The technical definition of Effective Embedment is the distance from the surface of the base material
to the deepest point at which the load is transferred to the base material; the “base material” in our
case being the Concrete into which the Anchor Bolts are being installed.)
Some people confuse Effective Embedment with Nominal Embedment, which is how far down into the
Hole the bottom of the Anchor Bolt is.
As shown below, the two are not the same. Nominal Embedment is
not where the load is transferred
to the base material, Effective Embedment is.
Not necessarily to scale.
The Anchor Bolts shipped with your product have letters stamped into their tops, showing their length.
For example:
•4.75 in / 120 mm Anchor Bolts are stamped with a G.
•6.3 in / 160 mm Anchor Bolts are stamped with a J.
