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.

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.

1. With saddle fully lowered and pump piston fully

depressed, adjust wheel dolly to level position.

Removeoil fillerplug.

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
