JACKS WITH LIFTING CLAWS (TYPE C)
Claws are supplied as an accessory to
provide a low height lifting point. When fitted, lifting
must always and only be carried out on the toe of
the claw. See Figure 2.
The capacity of the claw is 40% of the capacity of
the jack to which it is fitted. Lifting claws must NOT
be fitted to threaded piston jacks. Lifting claws must
only be used with jacks having extended bases that
extend under the toe of the claw. They must ONLY
be used for vertical movements of loads.
The recess on the underside of the top of the claw
fits around the top of the piston. The heel of the
claw rests against the front face of the jack. Ensure
that the claw is seated properly before use and
that the toe is as far under the load as possible.
OPERATING POSITIONS
The Jack should be used in the two positions shown
below, See Figure 3.

STROKE LIMITER
PISTON STROKE LIMITING DEVICE:
For Operator safety, all JAH jacks are factory-fitted
with a fail-safe positive stop mechanism that
prevents the over-stroking of the piston under
loaded conditions beyond its maximum stated
travel length. If the jack is operated in the over-
stroke mode, oil is by-passed back to the reservoir
to prevent the piston travelling further than its
designed stroke distance.
If pumping of the jack with the operating lever is
continued with the piston in the over-stroke
operation mode, some oil may by-pass the stop
mechanism and appear at the top of the jack. If
this occurs, cease operating the jack and wipe off
any surplus oil.
PLEASE NOTE: That if the over-stroke
mechanism is operated and continuously pumped
with the piston under no load conditions, insufficient
pressure is achieved in the system to engage the
by-pass system of oil to the reservoir, and within a
short number of pumping actions, oil will appear at
the top of the jack.
OPERATING ENVIRONMENT
The jack is intended for use in industrial
environments, in or outdoors between temperatures
of -20 to +50°C. Outside these parameters, consult
Hi-Force Ltd, before use.
