Hi-Force JSS Jacks are despatched from the factory pre-filled with oil, and are ready for use.

They are only recommended for use in the vertical, upright position.

There is a Safety by pass valve to prevent over extension.

Using the Operating Lever Assembly turn Release Valve Screw clockwise to close.

Put Operating Lever into Handle Socket and operate pump. The piston will rise and lift load.

When the piston reaches full stroke the safety bypass valve will automatically prevent the piston

from rising further.

Using Operating Lever turn Release Valve Screw anti-clockwise to open. Opening Release

Valve SLOWLY will control rate of lowering. Do NOT overload Jack during lowering. Note:

piston will not retract under its own weight; a small load is required to return it.

Wipe piston clean before lowering. When Jack is not in use store upright with the piston

retracted in a clean environment.

ALWAYS

raise the piston to the load.

DO NOT

drop load onto the Jack.

ALWAYS

support the base of the Jack when in use.

NEVER

go under load when only the Jack supports it.

DO NOT

attempt to lift a load greater than the capacity of the Jack.

Before using any hydraulic equipment, read the operating instructions carefully and check that

they are fully understood.

Provide solid and flat foundations.

Make sure that there is sufficient spare lifting capacity and stroke when selecting Jacks.

Check Jack load ratings before use.
