LOWERING THE LOAD
WARNING! Before lowering the load, ensure that there are no obstructions underneath and that all
people are standing clear.
1. When the work is done, raise the load enough to carefully remove the jack stands.
2. Slowly and carefully lower the load by inserting the slotted end of the narrow handle into the
release valve and turning anticlockwise in extremely small increments. Release all pressure in
the jack.
3. Lower the extension screw by turning it clockwise as needed to remove the bottle jack.
WARNING! Dynamic shock loads are created by quick opening and closing of the release valve when
the lowering the load. The resulting overload may cause the hydraulic system to failure, which could
result in severe personal injury and/or property damage.
MAINTENANCE
1. Maintain the bottle jack with care. A bottle jack in good condition is efficient, easier to control
and will have fewer problems.
2. Inspect the bottle jack components periodically. Have a qualified technician repair or replace
damaged or worn components.
3. Check the ram every three months for any sign of rust or corrosion. Clean as needed and wipe
with an oil cloth.
4. An annual inspection of the bottle jack by a qualified technician is recommended.
5. Maintain the bottle jack’s labels and name plate. These carry important information. If
unreadable or missing, contact Princess Auto Ltd. for replacements.
CAUTION! Only qualified service personnel should repair the bottle jack.
PURGE THE HYDRAULIC SYSTEM
Purge the hydraulic system to eliminate any air in the system if the jack efficiency drops or jack
doesn’t work.
1. If the jack performs poorly during manual operation, use the slotted end of the narrow handle
to turn the release valve 1-1/2 turns anticlockwise. Remove the oil filler plug (#16) by gently
pulling. Insert the large handle into the handle bracket and pump it 10 to 15 times, then replace
the filler plug.
2. If the jack performs poorly when used with a compressor, connect the
