• Never use counter weight as a lift point• Position Jack perpendicular to the forklift .• Never lift from either end.

Lift only on those area of a forklift asrecommended by the forklift manufacturer.

OPERATIONLifting1. Place vehicle in park, with emergency brake on and wheels securely chocked to prevent inadvertent vehicle move-

ment.2. Locate and close release valve by turning release valve knob clockwise, firmly. Center jack saddle under lift point.3. Verify lift point, then use handle pump to contact lift point. To lift, pump handle until load reaches desired height.4. Transfer the load immediately to appropriately rated jack stands.

Lowering1. Raise load high enough to clear the jack stands, then carefully remove jack stands (always used in pairs).2. Slowly turn the release valve knob counterclockwise, but no more than 1/2 turn. If the load fails to lower:

a. Use another jack to raise the vehicle high enough to reinstall jack stands.b. Remove the malfunction jack and then the stands.c. Using the other jack, lower the load by turning the operating handle counterclockwise, but no more than 1/2

turn.

MAINTENANCEImportant: Use only a good grade hydraulic jack oil. Avoid mixing different types of fluid and Never use brake fluid,turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause failure of the jack and the potential forsudden and immediate loss of load. We recommend Hein-Werner HW93291 hydraulic oil or equivalent.

Adding oil1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug.2. Ensure the oil level is just below the oil filler plug hole. Reinstall the oil filler plug.

Changing oilFor best performance and longest life, replace the complete fluid supply at least once per year.1. With saddle fully lowered, remove the oil filler plug.2. Lay the jack on its side and drain the fluid into a suitable container.Note: Dispose of hydraulic fluid in accordance with local regulations.3. Ensure the oil level is just below the oil filler plug hole. Reinstall the oil filler plug.
