TO THE MODEL AND SERIAL NUMBER. This information is on a nameplate attached
to the leg assembly. Replacement parts are available from a local Autoquip distributor.
INSPECTION
Immediately upon receipt of the lift, a visual inspection should be made to determine
that it has not been damaged in transit. Any damage found must be noted on the
delivery receipt. In addition to this preliminary inspection, the lift should be carefully
inspected for concealed damage. Any concealed damage found that was not noted on
the delivery receipt should be reported in writing to the delivering carrier within 48 hours.
The following is a checklist that will aid you in the inspection of this lift:
1. Examine entire unit for any signs of mishandling. Pay special attention to the power
unit and pushbuttons.
2. Thoroughly examine all connections, making sure they have not vibrated loose
during transit, and inspect wiring for any signs of damage.
3. After installation, raise the lift and inspect the base frame, platform, scissors
assembly, and cylinder plumbing connections.

DANGERS, WARNINGS & CAUTIONS
Read and understand this manual and all labels prior to operating or
servicing the lift. All labels are provided in accordance with ANSI
Z535.4.
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. See "Lift
Blocking Instructions" section.
DANGER!
To avoid personal injury, stand clear of scissors leg mechanism while lift is
in motion.
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.

DANGERS, WARNINGS & CAUTIONS
DANGER!
Extending the platform length or width beyond the factory limit could cause
the unit to tip, which could result in personal injury or death.
DANGER!
Do not attempt to remove the velocity fuse until the maintenance locks
securely support the lift and all hydraulic pressure has been removed from
the lifting cylinders and hydraulic hoses. Failure to do so could result in
personal injury or death!
WARNING!
Do not operate this equipment without handrails and snap chains in place.
WARNING!
Under no circumstances should the speed control orifice be removed from
the Deltatrol to obtain faster lowering speed. A loaded lift can reach
dangerous and destructive speed!!
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 an Autoquip representative for
replacements.

DANGERS, WARNINGS & CAUTIONS
CAUTION!
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.
CAUTION!
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.
CAUTION!
Do not operate the power unit on relief for more than a few seconds. When
on relief, the valve will make a squealing sound.
CAUTION!
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.
CAUTION!
Use only approved oils in the lift. See “Specifications” section.

NOTE: All PDQ Models have a standard 5 HP motor (230/60/3) with a nominal standard
speed of 15 fpm, and have two rams.
All PDQ Scissors Lifts have a rollover capacity equal to twice the lifting capacity when in
the fully lowered position.
The PDQ can handle pallets, carats, electric walkie and hand trucks. Although the PDQ
is designed to unload freight, it can also be used for loading. Using a PDQ, one person
can load or unload a full trailer safely in 25 to 30 minutes, using a pallet jack.
LOAD CAPACITY
The load capacity rating is stamped on a metal plate attached to the lift. This figure is a
net capacity rating for a lift furnished with the standard platform. The relief valve of the
pumping unit has been set to raise the weight, plus a small amount for overload. Where
gravity roll-sections, special tops, etc, are installed on the lift after leaving the plant,
deduct the weight of these from the load rating to obtain the net capacity. Lifts should
not be overloaded beyond the established capacity as damage and/or personal
injury may result.
