operating or servicing the lift. All labels are provided in
accordance with ANSI Z535.4.
DANGER !
Do not work under the lift without a Maintenance Device! To avoid personal
injury, NEVER go under the lift platform until the load is removed and the
scissors mechanism is securely blocked in the open position. See "Lift
Blocking Instructions" section.
DANGER !
Do not install the lift in a pit unless it has a bevel toe guard or other approved
toe protection. A shear point can exist which can cause severe injury to the
foot.
DANGER !
HIGH VOLTAGE!! Disconnect and/or lock out the electrical supply to the
power unit prior to any maintenance being performed.
DANGER !
Scissors lifts are designed individually for a specific load and application. To
avoid personal injury, do not change the load or application from the original
design.
DANGER !
Failure to relieve lift system pressure could result in the sudden and
unexpected release of pressure during maintenance and/or repair of the lift
and result in severe injury to the personnel and/or damage to the lift.
6
SAFETY PRACTICES
WARNING !
Do not make modifications to the lift such as extending the platform length
or width, this could cause the platform to tip. Do not add unauthorized or
unspecified components to the lift. Modifications to the lift can result in unsafe
operating conditions which could lead to serious injury or death.
WARNING !
If the lift is equipped with handrails, do not operate this equipment without handrails
and snap chains in place.
WARNING !
Under no circumstances should the down flow control valve be removed, from
the Contractor Power Unit or the Deltatrol on the Vertical Power Unit, to obtain
faster lowering speed. A loaded lift can reach dangerous and destructive
speed.
WARNING !
Do not attempt to remove the velocity fuse until the maintenance block
securely supports the lift and all hydraulic pressure has been removed from
the lifting cylinders and hydraulic hoses. Failure to do so could results in
personal injury or death.
WARNING !
To avoid personal injury, stand clear of scissors leg mechanism while lift is
in motion.
7
SAFETY PRACTICES
WARNING !
All warning and information decals should be in place as outlined in the “Label
Identification” section. If decals are missing or damaged, they should be
replaced with new ones. Contact Autoquip for replacements.
WARNING !
Lift platforms traveling below floor levels my create openings, and the shape
of the load and how the load is arranged on the lift may create a toe hazard as
the load passes the top edge of the pit. Both situations may require guarding
in accordance with Federal Regulations. Any such guarding must be installed
prior to operating the lift
WARNING !
The hydraulic velocity fuse (HVF) must be properly installed! The HVF is
attached to the elbow fitting in the trust angle port (casing end) of the cylinder.
Do not use a swivel fitting between the HVF and cylinder. If the HVF is
installed improperly, it will not lock up in the event of a catastrophic hydraulic
line break.
WARNING !
Use properly rated hoses only! Never use fittings or hoses that are not
properly rated for the intended use. Contact Autoquip for replacements.
WARNING !
Never exceed the rated capacity of the lift! Overloading, or uneven
loading, could result in load instability and cause serious personal injury.
8
SAFETY PRACTICES
WARNING !
Any lift which has a hinged throw-over bridge damaged to the point of hanging
more than 30 degrees below horizontal is in violation of the safety standards
set forth in ANSI MH29.1 and MUST be taken out of service until the bridge is
repaired or replaced. Failure to do so could result in severe personal injury.
WARNING !
Lifts should not be overloaded beyond the established capacity as damage
and/or personal injury may result.
WARNING !
Only trained and qualified personnel should operate this equipment.
WARNING !
Whenever raising or lowering the lift, personnel should maintain a safe
operating distance of at least 36” to avoid personal injury.
WARNING !
Any time the velocity fuses (HVF) have been tripped, the owner must
investigate the cause of the trip and ensure any necessary corrective actions
been taken, prior to resumption of normal lift operation. Failure to do so could
result in personal injury.
CAUTION !
Spilled oil is very slippery, and may also present a fire hazard. Clean up all
spilled oil to prevent personal injury or equipment damage.
9
SAFETY PRACTICES
NOTICE!
Do not continue to depress the “UP” button on the controller if the lift is not
raising or if the lift has reached the fully raised position. To do so may result
in permanent damage to the motor or pump.
NOTICE!
Never run the pump for more than a couple of seconds without pumping oil.
This applies to low oil conditions, improper motor rotation, running the pump
against the relief pressure after the lift is fully raised against the physical
stops, running overloaded beyond capacity, or running at reduced speed
because of pinched or obstructed hydraulic lines.
NOTICE!
Do not operate the power unit on relief for more than a few seconds. When
on relief, the valve will make a squealing sound.
NOTICE!
Precautions should be taken to prevent the introduction of contaminates such
as dirt or other foreign material into the system through open fittings, pipes or
disassembled components. Contamination will ruin the hydraulic system.
NOTICE!
Use only approved oils in the lift. See “Specifications” section.

LOAD CAPACITY
The load capacity rating is stamped on a metal nameplate that is attached to one side of
the lift Leg assembly. This load capacity rating is a net rating for a lift furnished with the
standard minimum platform. Each platform size listed above in Lift Specifications is the
Standard (Minimum) platform size for each model lift. The relief valve on the power unit
has been set to raise the lift capacity, plus a small amount for overload. When gravity roller
conveyors, fixtures, or special tops, etc, are installed on the lift platform,
after leaving the plant, deduct the weight of these components from the load rating to
obtain the net lifting capacity.
15
SPECIFICATIONS
CAUTION!
Lifts should not be overloaded beyond the established capacity as
damage and/or personal injury may result and will void its
warranty.
DANGER!
Do not make modifications to the lift without authorization
from the manufacturer. Autoquip cannot foresee and is
not responsible for injury or damage which results from
the unauthorized modifications or misuse of the lift.
UNBALANCED LOADING
The stabilization provided is basically for balanced loads. If special attachments extend
beyond the length and/or width dimensions of the platform, the end and/or side load
capacity must be reduced (contact an Autoquip Sales representative).
LIFT DUTY
Autoquip standard lift designs as described in the specifications typically include
intermittent duty motors and are designed to “cycle” (one complete “up” and one complete
“down” lift operation) no more frequently than every two minutes – or approximately 60,000
times (cycles) per year. This is considered “normal” duty.
It is the responsibility of the user to notify Autoquip whenever a specific application is likely
to demand “above normal” duty from the lift - in excess of 60,000 cycles per year. Above
normal duty typically requires supplemental design features to enhance the serviceable life
of the lift & to avoid loss of warranty.
PUMP PRESSURE
This lift incorporates a positive displacement pump machined to a high degree of accuracy
and specially adapted to requirements of higher-pressure ranges over that of a standard
pump. Therefore, standard factory models of the same manufacture cannot replace it.
The pump can operate efficiently at intermittent pressures up to 3200 PSI and continuous
duty to 2500 PSI. The safety relief valve in the pump assembly or Deltatrol Valve is
factory-set to stay within the parameters of the pump and lift requirements.

LIFT BLOCKING INSTRUCTIONS
WARNING !
Only authorized personnel should perform inspection or
maintenance and service procedures. Unauthorized personnel
attempting these procedures do so at the risk of personal injury or
death.
DANGER !
Failure to properly adhere to lift blocking procedures is to risk the
sudden and uncontrolled descent of the lift during maintenance or
inspection. A falling lift can cause severe injury or death.
LIFT BLOCKING PROCEDURE
This procedure describes the only factory-approved method of working under a lift. Follow
these instructions EVERY time you plan to reach or crawl beneath the lift to
perform service or maintenance – no matter how momentary that might be.
If the factory-provided maintenance device is damaged or missing, stop immediately and
consult the factory for assistance. The manufacturer is not liable for your failure to use the
approved maintenance devices and procedures that have been provided.
1. All loads must be removed from the lift prior to engaging the maintenance device.
The maintenance device is designed to support an unloaded lift only. Failure to
remove the load from the lift prior to blocking could cause the failure of the
maintenance device and allow the lift to fall unexpectedly. This can result in
personal injury or death, or permanent damage to the maintenance device and/or
the lift.
2. Raise the lift to its fully raised position. If you do not, the maintenance device may
not be able to be placed properly in its designed blocking position.
3. Locate and engage all maintenance devices.
a. Flip-over maintenance locks are permanently welded on the side the base
frame on the roller end of the lift base frame. Both locks must be flipped over
and resting inside the base frame and thus blocking the path of the base
rollers. (See Figure 9A).
– (Reference Figures: 2A & 2B)
17
LIFT BLOCKING INSTRUCTIONS
LIFT BLOCKING PROCEDURE– (Reference Figures: 9A & 9B)
b. Maintenance leg is connected to the base frame by a chain. Remove the
maintenance leg from its storage location. Place one end of the maintenance
leg in the leg socket located in the base frame on the Clevis End, (See Figure
9B). Lower the lift platform until it comes down and makes contact with the
maintenance leg. The maintenance leg should be centered in the platform
maintenance leg socket, located underneath the platform on the Clevis End.
Re-check to ensure that the maintenance leg device is inside the platform
maintenance socket and in contact with the platform deck surface. If the
maintenance leg is not fully engaged the lift could fall unexpectedly, resulting
in permanent damage to the devices or the lift.
DANGER !
Do not work under lift, without Maintenance Device! To avoid
personal injury, NEVER go under the lift platform until the load is
removed and the scissors mechanism is securely blocked in the
open position and the appropriate OSHA lock-out/tag-out
procedure is followed. See "Lift Blocking Instructions" section.
DANGER !
If for any reason you are unable to lower the lift completely onto
the maintenance device(s), stop immediately and consult the
factory. Failure to properly use the factory approved maintenance
device(s) could result in severe injury or death.
4. Once the maintenance device(s) is properly and securely engaged continue to
press the down button for an additional 5-10 seconds to relieve all pressure in the
system (it could take longer in a pneumatic system).
WARNING !
Failure to relieve the system operating pressure could result in the
sudden and unexpected release of high-pressure fluids (or air)
during maintenance and/or repair of the lift and result in severe
injury or death.

5. Follow OSHA electrical lock-out/tag-out procedures. Disconnect and tag all
electrical and/or other power sources to prevent an unplanned or unexpected
actuation of the lift.
6. Once inspection or work is complete reverse steps 1-5 above, raise the lift off the
maintenance device and place the maintenance device back into the designated
storage position.
21
INSTALLATION INSTRUCTIONS
WARNING!
Before installing the lift, read & follow the recommended safety practices
in the Safety Practices section. Failure to follow these safety practices
could result in death or serious injury
FLOOR INSTALLATION
1. Make sure the installation area is clean before starting. Check the mounting
surface of the floor with a level or straight edge. If the floor is not level, add
shims or grout under the lift base frame along the entire perimeter of the base to
achieve a level and flat base installation. A level base will ensure proper wheel
tracking and smooth lift operation.
2. If the permanent electrical work is not complete, some means of temporary lines
with an on-off device for the power supply should be set up for testing purposes.
3. Place the lift in the installation area and level the base frame per note #1.
NOTICE !
When moving the lift, do not attempt to pick it up by the
platform, the platform is hinged and could be damaged. Pick up
the lift from under the base frame ONLY using a strap sling.
4. Make temporary electrical connections and permanent hydraulic connections.
Raise the lift approximately one foot using the “UP” button. Then lower the lift
back to fully collapse, holding the “DOWN” button for approximately 60 seconds.
Repeat this process five to seven times to bleed any air out of the hydraulic
system.
DANGER !
HIGH VOLTAGE!! – Disconnect and/or lock out the electrical supply
to the power unit per OSHA regulations prior to any installation or
maintenance being performed.
5. Raise the lift to the top of its travel and make positioning adjustments. Check for
the proper height. If needed, shim to the desired height. DO NOT “spot” shim.
Shim the full length of the base frame. This will prevent the frame from sagging
under an exceptionally heavy load.
