HOW TO USE
1. Set emergency brake, chock tires of diagonally
opposedwheel(s)inbothdirectionsAND take every
precaution necessary to ensure set up is stable and
preventinadvertentvehiclemovement.
2. When tire & wheel assembly are ready to remove,
position wheel dolly to accept tire & wheel assembly
and secure load with restraint.
3. Use jack handle to turn release valve clockwise until
tight.DONOTOVERTIGHTEN.Insertjackhandleinto
handle sleeve of hydraulic unit and pump until lifting
armsreach desired height.
Note: Do not use wheel dolly to free a seized up wheel
assembly. For typical practice of taking out a seized
up wheel assembly, a long metal bar can be used to
pry the wheel assembly from the stuck wheel axle. If in
doubt,always follow vehicle’s manufacturer manual on
how to remove tire & wheel assembly.
4. Use load leveler to adjust the angle.
5.Carefullymoveloadedwheel dolly away from hub.

MAINTENANCE
Important: Use only a good grade hydraulic jack oil.
Avoidmixing different types of fluidand NEVER use
brake fluid, turbine oil, transmission fluid, motor oil or
glycerin.Improper fluid can cause prematurefailureof
the jack and the potential for sudden and immediate
loss of load. We recommend Mobil DTE 13M or
equivalent.

depressed, adjust wheel dolly to level position.

2. Fill until oil is level with the filler plug hole, reinstall oil
fillerplug.
Changing oil
Forbest performance, replace the fluid at least once per
year.
1. With saddle fully lowered and pump piston fully
depressed,removejack from leveler assembly,then
removethe oil filler plug.
2. Lay the jack on its side and drain the fluid into a
suitablecontainer.
