5.3 Operating Orientation
jack body. If full support of the base plug can be achieved, the JCS jack can be used in any orientation. The
jack must not be used with the base plug partially supported to prevent damage and/or injury.
The load bearing area is shown above, highlighted yellow.
5.4 Placing the Jack
Carefully determine the jacking/loading point of the item to be lifted/moved, taking the following into
consideration:
1. Make sure the jacking/loading point is strong enough to withstand the load that will be applied
to it, without damaging the object being lifted/moved. If necessary place suitable material
between the load point and the jack ram to avoid damaging the structure to be lifted/moved.
2. Ensure the chosen loading point will not cause the structure to topple or shift unexpectedly
when the piston is extended. If necessary put additional safety measures in place (eg.
Rigging, blocking) to limit any unexpected movement of the load.
Place the jack on a firm, level foundation capable of supporting the load to be lifted/moved, whilst
fully supporting the jack base plug (6). Where necessary, use an additional support base of suitable
material to support the jack and distribute the load evenly across its base.
DO NOT position the jack by using the operating lever in the release valve. If the jack is to be placed
some distance under the load, use the operating lever in the operating lever/quadrant socket to
position the jack.
ALWAYS ensure the jack's piston contacts the load to be lifted as squarely as possible.
JCS jacks are designed so that the base plug (6) protrudes the jack body (5). This
is to ensure that any load is borne by the steel base plate and not the aluminium
