OPERATION
(ref. Figures 1 and 2)
VEHICLE PREPARATION
1. Position vehicle on a hard, level surface, such as reinforced concrete, large enough to accommodate vehicle, jacks,
jack stands, and wheel dolly.
2. Set the vehicle emergency brake unless the rear drum, tire and wheel are all to be removed as an assembly.
3. Chock all unlifted tires in both directions and take every precaution necessary to ensure the set up is stable and will
prevent all inadvertent vehicle movement.
RAISING THE LIFTING ARMS
1. Locate and enagage the release valve using the provided handle assy, then turn handle clockwise until firm
resistance is felt to further thread engagement.
WARNING:
Follow the vehicle manufacturers recommended removal and installation procedures for tire, wheel,
hub, or axle assemblies as needed!
Do not
remove more than is recommended by the vehicle manufacturer.
2. After the tire, wheel assembly has been loosened from the hub or axle and is ready to be removed, position the
dolly under the assembly to be removed. Pump until load reaches desired height. Adjust lift arm tilt such that the tire
and wheel assembly will rest securely between the lift arms without falling.
LOADING THE WHEEL DOLLY
WARNING:
Never load this device with more than the weight of the wheel assembly to be removed. Ensure that
the vehicle is securely positioned and supported by a pair of appropriately rated jack stands.
WARNING:
Never use a wheel dolly as a wheel pulling device. Before transporting wheel assembly, ensure that
it is free from the hub or drum assembly and secured to the wheel dolly with the provided restraint
.
1. When the weight of the loosened tire and wheel assembly is supported by the wheel dolly, carefully roll the wheel
dolly away from the drum or axle.

PREPARATION
(cont.)
4. To familiarize yourself with basic operation, position hydraulic unit upright as shown in Fig. 2., locate and engage
release valve with slotted portion of provided handle, then turn release valve:
a.
Clockwise
until firm resistance is felt to further turning. This is the ‘
CLOSED
’ release valve position used to
raise
the load.
b.
Counter-clockwise
, but no more than 1 turn from the closed position. This is the ‘
OPEN
’ release valve position
used to
lower
the load.
5. With ram plunger fully lowered, locate and remove the oil filler plug. Insert the handle into the handle sleeve then
pump 6 to 8 full strokes. Check oil level. Proper level is oil even with the bottom of the oil filler plug hole. Adjust as
needed, reinstall the oil filler plug.
6. Place the hydraulic unit (Fig. 2) into the hydraulic unit holder located beneath the lifting frame. Position the unit
such that the saddle mates with the vertical tube under lifting frame.
7. Check to ensure the wheel dolly rolls freely and the hydraulic unit operates smoothly before putting into service.
Lubricate as instructed in Maintenance Section.
Bleeding/Venting Trapped Air in Hydraulic Unit
With the release valve in the OPEN position (4b above) and with saddle fully lowered, locate and remove the oil filler
plug. Insert the handle into the handle sleeve; then pump 6 to 8 full strokes. This will help release any pressurized air
which may be trapped within the reservoir. Reinstall the oil filler plug.
