BEFORE USE
(refer to Figures 1,2, and 3)
1. Verify that the product and the application are compatible, if in doubt call Hein-Werner Technical Service (816) 891-
6390.
2. Before using this product, read the owner's manual completely and familiarize yourself thoroughly with the product,
its components, and recognize the hazards associated with its use.
3. Assemble the handle for hydraulic unit.
4. To familiarize yourself with basic operation; position the hydraulic unit upright as shown in Fig. 2., assemble the handle,
locate and engage the release valve with the slotted portion of the provided handle, then turn the release valve:
a. Clockwise until firm resistance is felt to further turning of the handle. 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 oil level is level 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 tool tray. Position the unit such
that the saddle mates with the provided indentation. Adjustment of the saddle extension screw may be necessary.
7. Check to ensure the wheel dolly rolls freely and the hydraulic unit operates smoothly before putting into service.

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.
If necessary, use the hydraulic unit handle to engage the
Lift Arm Level Control lever to allow easier operation.
