SETUP OPERATING MAINTENANCE INSTRUCTIONS
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.
IMPORTANT: READ THESE INSTRUCTIONS BEFORE OPERATING
BEFORE USING THIS WHEEL DOLLY, READ THIS MANUAL
COMPLETELY AND THOROUGHLY, UNDERSTAND THEIR
OPERATING PROCEDURES, SAFETY WARNINGS AND
MAINTENANCE REQUIREMENTS. FAILURE TO DO SO COULD
CAUSE ACCIDENTS RESULTING IN SERIOUS OR FATAL
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
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 qualied 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.
WARNING
Inspect the wheel dolly before each use. Do not use the wheel •
dolly if it is damaged, altered, modied, 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.
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
of the device owner to keep these manuals intact and in a convenient
location for all to see and read. If the manuals are lost or not
legible, contact Norco Industries, Inc. for free replacements. If the
operator is not uent in English, the product and safety instructions
shall be read to and discussed with the operator in the operator’s
native language by the purchaser/owner or his designee, making
sure that the operator comprehends its contents.
WARRANTY
This product is covered by a Limited Lifetime Warranty. For details
see the back cover of Norco’s product catalog.
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 modications shall be made to this product.•
Insert the large diameter end of the jack handle into the pump 1.
handle receiver and secure the handle to the receiver with the
washer and bolt provided.
Sometimes air gets trapped in the hydraulic bottle jacks 2.
causing the jack ram to extend in sporadic increments instead of
one smooth extension.
SETUP
PURGING AIR FROM THE MANUAL PUMP SYSTEM
Open the release valve by turning the release valve knob in a.
a counterclockwise direction two full turns.
Pump the handle ten full strokes.b.
Close the release valve by turning the release valve knob in c.
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.
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.
To raise the arms a small distance it is necessary to use incremental
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.
PREVENTATIVE MAINTENANCE
Always store the wheel dolly in a well protected area where 1.
it will not be exposed to inclement weather, corrosive vapors,
abrasive dust, or any other harmful elements. The wheel dolly
must be cleaned of water, snow, sand, or grit before using.
Lubricate moving parts once a month with a general purpose 2.
grease.
It should not be necessary to rell or top off the reservoir with 3.
hydraulic uid unless there is an external leak. An external leak
requires immediate repair which must be performed in a dirt-
free environment by qualied hydraulic repair personnel who are
familiar with this equipment. Norco Authorized Service Centers are
recommended. IMPORTANT: In order to prevent seal damage
and hydraulic failure, never use alcohol, hydraulic brake uid,
or transmission oil in the hydraulic system.
After the vehicle is raised and correctly blocked, push the 3.
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 safety 4.
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 weight 5.
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.
Every wheel dolly owner is responsible for keeping the dolly 4.
label clean and readable. Use a mild soap solution to wash external
surfaces of the dolly but not any moving hydraulic components.
Contact Norco Industries for a replacement label if your dolly label
is unreadable.
Inspect the wheel dolly before each use. Do not use the dolly if 5.
any component is cracked, broken, bent, shows signs of damage,
or leaks hydraulic uid. Do not use the dolly if it has loose or
missing hardware or components, or is modied in any way. Take
corrective action before using the dolly again.
Do not attempt to make any hydraulic repairs unless you 6.
are a qualied hydraulic repair person that is familiar with this
equipment.
