This jack is fitted additionally with a low pressure pump intended for faster movement of the
ram under no load. i.e. to close daylight. The low pressure quadrant is on the left hand side of
the jack and operates in the same manner as the high pressure pump.
Stroke Limit
The jack is fitted with an internal by -pass valve which prevents the ram stroke exceeding the
design limit. If the jack is operated in this condition, oil passes back to the reservoir. If operation
is continued, some oil may by -pass the ram scraper ring and appear on the top of the jack. Cease
operating the jack, wipe off surplus oil and check the oil lev el of the jack .
Operating Positions
The jack should only be used in the positions shown below:
Oil Level Check
Remove the dipstick (see Fig. 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 the level.
If oil needs to be added ensure that the surrounding area is clean. Use high quality hydraulic oil
such as Shell Tellus ISO 32 or equivalent.
