Supporting the Jack
Before use always ensure the jack is fully supported on a
fl
at,
fi
rm 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 e
ff
ort is necessary to move the
operating lever.
Do not continue pumping after this has been reached.
Lowering
Place the operati ng lever in the operating socket and ensure that the end of the lever is engaged
in the release valve. Carefully turn anti -clockwise. If the jack is under load, turn only a small
amount, (approx. 5°); in the
fi
rst instance which will allow the speed of des cent to be controlled
by the further extent of the valve opening.
Maintenance
In the normal course of service, no routine maintenance should be required, but attention to the
following will assist in obtaining satisfactory service.
The oil level should be periodically checked; the reservoir should not be ove
rfi
lled. Always use
clean oil of the type speci
fi
ed.
Always wipe the claw/ram extension clean before retracting. Lightly grease the claw tenons
occasionally.
Inspect and clean ram and jack after ev ery use, if subjected to abnormal or shock loading
inspect for damage immediately.
Refer to authorised service centre for testing and service.
