BEFORE USE
Before using this jack, ensure that the intended load contact
point is able to withstand the load applied by this jack.
1. 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.
2. To familiarize yourself with basic operation, use the operating
handle to engage and turn the release valve:
a. Clockwise until rm resistance is felt to further thread
engagement. This is the ‘CLOSED’ release valve
position used to pressurize the hydraulic uid and
raise the ram plunger.
b. Counter-clockwise, but no more than 1/2 turn from the
closed position. This is the ‘OPEN’ release valve
position
used to lower the ram plunger.
3. Check that the pump operates smoothly before putting into
service. Replace damaged or missing parts with factory
authorized replacement parts only. Repair of this product
may require special skills and knowledge and should only
be attempted by a factory authorized service center. Contact
the manufacturer or distributor of this product for a list of
factory authorized service centers. Lubricate as instructed
in Maintenance Section.
Bleeding/ Venting Trapped Air

saddle fully lowered, locate and remove the oil ller 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. Oil level should be even with the bottom of
the oil ller plug hole. Reinstall the oil ller plug.
