necessary place suitable material between
the load point and jack ram to avoid
damaging the structure to be lifted.
Use the jack by operating the lever in a
steady controlled movement at a
maximum of 30 strokes per minute.
Remove the operating lever when not in
use.
The ram should only be extended
hydraulically; it should never be pulled out
by hand or used to carry the jack.
SAFETY.
READ THIS MANUAL BEFORE OPERATING THE JACK.
FAILURE TO OBSERVE THE FOLLOWING WARNINGS
COULD RESULT IN SERIOUS BODILY INJURY.
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.
Do not attempt to exceed the rated load
on the head or toe of the jack.
The maximum working load and the travel
of the hydraulic jack is marked on the
equipment,
In operation, never drop loads onto the
jack. Always raise the head/toe to the
load.
Always ensure the full base area of the jack
is supported when in use.
Always ensure that loads are applied
centrally to the ram, or to the full extent of
the claw.
DO NOT allow any persons to work under
the load, when it is only supported by
hydraulic jacks.
Always clean the ram and retract it after
use.
Always remove the jack operating handle
when not in use.
Do not use if there is evidence of oil
leakage.
Never extend the ram by any means other
than pumping the jack.
Inspect and clean the jack after every use,
but if subjected to abnormal or shock
loading inspect for damage immediately.
CHECKING THE OIL LEVEL.
The jacks are normally supplied filled and ready for
use. However before using the jack for the first time,
the oil level should be checked. The oil used should
be a high quality hydraulic oil of HVI ISO46 viscosity,
e.g. Hi-force HFO32.
Remove the dipstick (See figure 1) and check the
oil level. The maximum level is marked on the

dipstick. The level should be within 5mm of this
mark. The dipstick should be screwed fully into
position to determine this level.
OPERATION OF JACK. See Figure 1.
Note: The permissible working load and stroke
of the Jack are marked on the side.
The JAH series Jacks (1) have an in-built hydraulic
pump which is worked by means of an operating
lever (2), under the control of the operator. The
piston (3) is raised on each downwards stroke of the
lever. For lifting, the lever is placed fully into the
operating quadrant (4). Three positions are
provided to enable the user to choose the best
ergonomic position. For lowering, the piston the
lever is removed from the quadrant and placed
into the release screw (5). Turning this anticlockwise
will allow the piston to descend. The amount this is
rotated will control the speed of decent. Only open
a very small amount (approx. 5°) at first. Rotate
clockwise, hand tight after use, to ready the jack for
the next operation.
JACKS WITH LOCKING COLLARS (TYPE SR)
All models can be supplied with threaded
pistons and locking collars to mechanically support
the load without relying on the hydraulic circuit.
When the load is at the required position, rotate the
locking collar clockwise until it rest hand-tight on
the top of the jack body.
To undo – operate the jack so that the hydraulic
circuit just takes the load of the locking collar.
Rotate the collar anticlockwise until it reaches the
top of the piston.
