PREPARATION (REFER TO FIGURES 3 & 4)
Before Use
1. Verify that the product and application are compatible, if in doubt call
2. Before use, read the operator's manual completely and familiarize yourself thoroughly with the product, its components
and recognize the potential hazards associated with its use.
3. To familiarize yourself with the basic operation of these jacks, locate and turn the release valve knob:
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 1/2 full turn from the closed position. This is the 'OPEN' release valve position
used to lower the load. The more you turn the release valve knob Counter-clockwise, the faster the load descends.
4. With saddle fully lowered, locate and remove cover plate, then remove air vent screw. Pump the operating handle
through 6 to 8 full strokes. Check the oil level. Ensure the oil level is within ~3/16" from the inner cylinder as viewed
from the air vent screw hole.
5. Reinstall the air vent screw.
6. Check to ensure that the jack rolls freely. Raise and lower the unloaded saddle throughout the lift range before
putting into service to ensure the pump and release valve operate smoothly.
7. Replace worn or damaged parts and assemblies with Hein-Werner Replacement Parts only. Lubricate as instructed
in Maintenance Section.
