PREPARATION (ref. Figures 3 & 4)
Before Use
1. Verify that the product and application are compatible, if in doubt contact Hein-Werner Technical Service.
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 rm 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 further the release valve knob is turned counter-clockwise, the faster the load will descend.
4. Reinstall the air vent screw.
5. Check that the jack rolls freely. Raise and lower the unloaded saddle throughout the lift range to ensure the pump
and release valve operate smoothly.
6. Replace worn or damaged parts and assemblies with Hein-Werner Replacement Parts only. Lubricate as instructed
in Maintenance Section.
Bleeding/Venting Trapped Air - With saddle fully lowered, remove cover plate then remove air vent
screw. Pump the operating handle through 6 to 8 full strokes. Ensure the oil level is within ~3/16" from the inner
cylinder as viewed from the air vent screw hole.
ASSEMBLY
Equipment required:
1. Needle nose locking pliers

with the holes on the side plates that the pivot pin
was removed from and tighten the 5/8"-18 bolts into
the pivot pin until secure.
