The use of wheel dollies is subject to certain hazards that cannot
be prevented by mechanical means, but only by the exercise of
intelligence, care, and common sense. It is therefore essential to
have owners and personnel involved in the use and operation of
equipment who are careful, competent, trained, and qualied in
the safe operation of the equipment and its proper use. Examples
of hazards are dropping, tipping, or slipping of loads caused
primarily by improperly securing loads, overloading, off-centered
loads, use on other than a hard level surface, and using equipment
for a purpose for which it was not designed.
It is the responsibility of the owner to make sure all personnel read
these manuals prior to using this device. It is also the responsibility

WARNING
Inspect the wheel dolly before each use. Do not use the wheel•
dolly if it is damaged, altered, modied, in poor condition,
leaking hydraulic uid, or has loose or missing hardware or
components. Take corrective action before using the wheel
dolly.
Do not exceed rated capacity. Use only on a hard level surface.•
Stay out from underneath a load that is being lifted or• suspended.
Apply load as close to the vertical portion of the lifting member• as possible.
Before moving the load, assure that the load is centered and• secured with the load restraint device provided.
Before moving, lower the load to the lowest possible point.•
No alterations or modications shall be made to this product.•
SETUP
Insert the large diameter end of the jack handle into the pump1.
handle receiver and secure the handle to the receiver with the
washer and bolt provided.
Sometimes air gets trapped in the hydraulic bottle jacks2.
causing the jack ram to extend in sporadic increments instead of
one smooth extension.
PURGING AIR FROM THE MANUAL PUMP SYSTEM
Open the release valve by turning the release valve knob ina. a counterclockwise direction two full turns.
Pump the handle ten full strokes.b. Close the release valve by turning the release valve knob inc. a clockwise direction until tight.
Pump the jack until the ram is extended to maximum height.d. If the condition remains, repeat steps “a” through “d” until air
is purged from the system.
Note: Revision letters (A, B, C, D etc.) after model numbers have been omitted as they do not affect the setup,
operating and maintenance instructions of a particular jack unless otherwise noted.

OPERATING INSTRUCTIONS
Hydraulic bottle jacks are used on every model wheel dolly.1.
Become familiar with the operation of the bottle jack. The jack’s
release valve knob must be turned in a clockwise direction until
tight before the jack can be pumped. Turning the release valve
knob very slowly in a counterclockwise direction lowers the load in
a safe controlled manner. There should never be a reason to turn
the release valve knob in a counterclockwise direction more than
two full turns. The bottle jack tilts the lift arms in order to match the
angle of the spindle.
IMPORTANT:2. Become familiar with the pedal operation of the
air/hydraulic foot pump before using the wheel dolly under load.
Depressing the foot pedal end marked “Pump” raises the lift arms.
Toraisethearmsasmalldistanceitisnecessarytouseincremental
taps of your foot on the foot pedal until the arms reach the desired
height. Lowering the arms is accomplished by depressing the foot
pedal end marked “Release”. The pump is equipped with a two
speed release mechanism. Gently depressing the foot pedal end
marked “Release” lowers the arms slower than if you depress the
pedal all the way down. If you want to lower the load slower than
the slow speed release, use gentle incremental taps of your foot
on the “Release” pedal.
After the vehicle is raised and correctly blocked, push the3.
wheel dolly in towards the tire/wheel combination to be lifted. The
wheel dolly lift arms should straddle the tire and the side wall of
the tire should be as close as possible to the vertical portion of the
lift member. Raise the lift arms to meet the tire/s and adjust the lift
arm angles so the arms are in full contact with tire/s. If the lift arms
are not exactly centered on the tire/wheel, rotating the side shift
knob clockwise will adjust the lift arms right and counterclockwise
will shift them left.
Secure the tire/wheel combination to the dolly with the safety4.
restraint chain provided. Wrap the chain around the tire and secure
the chain hook or chain loop to the dolly.
Continue to lift the tire/wheel combination until the entire weight5.
is supported by the dolly lift arms. Back the dolly away to remove
the tire/wheel combination.
Slowly lower the load to the ground or desired work height.6.
Never raise, lower or transport a load without the safety restraint
chain securing the load.
