OPERATING POSITIONS
The Jack should be used in the two positions shown below, ONLY. See
Figure 3.
STROKE LIMITER
The Jack is factory fitted with an internal by-pass valve which prevents the
jack piston exceeding maximum stroke. If the jack is operated in this
condition, oil passes back to the reservoir. If operation is continued, some oil
may by-pass the jack stop ring and appear on the top of the jack. Cease
operating jack and wipe off surplus oil.
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.
