Before use always ensure the jack is fully supported on a flat, firm surface with due regard to
the load to be lifted.
Position the jack so that the load bears centrally on the top of the ram or on the full extent of the
claw, ensuring that the load cannot touch any static part o f the jack during lifting.
Lifting
The release valve (2) is located inside the operating socket (3) and can be opened or closed by
engaging the end of the operating lever. Turning clockwise closes the valve; excessive force is
unnecessary and could lead to damage. With the release valve closed and the operating lever in
the socket, reciprocate the lever to operate the jack.
The ram will extend on each downward stroke of the lever. When the full extension has been
achieved a positive stop is engaged; fur ther pumping will only circulate oil within the jack. This
circulation will be apparent to the operator because increased effort is necessary to move the
operating lever.
Do not continue pumping after this has been reached.
Lowering
