MAINTENANCE
Monthly maintenance is recommended.
Lubrication is critical to jacks as they support
heavy loads. Any restriction due to dirt,
rust, etc. can cause either slow movement
or cause extremely rapid jerks, damaging te
internal components.
The following steps are designed to keep
the jack maintained and operational.
1. Lubricate te ram, linkages, saddle and
pump mechanism will light oil.
2. Visually inspect for cracked welds, bent,
loose, missing parts or hydraulic oil leaks.
3. The product
immediately if it is believed to have been
subjected to abnormal load or shock.
4. Any hydraulic jack found damaged in
any way, is found to be worn or operates
abnormally shall be removed from service
until repaired by an authorized customer
service representative.
5. Clean all surfaces and maintain all labels
and warnings.
6. Check and mantain the ram oil level
7. Check the ram every three months for any
sign of rust or corrosion. Clean as needed
and wipe with an oil cloth. When not in
use, always leave the saddle and ram all
the way down.
Always keep the jack on the way down.
This will help protect the most critical areas
of corrosion. Do not use brake fluid or
transmission or common motor oil as they
may damage the seals. Always buy and use
hydraulic oil labeled as jack.
CONTROL OIL LEVEL
1. Turn release
to allow ram to fully retract. it may be
necessary to apply force to the saddle for
lowering.
2. Remove the inspection plate.
3. With the jack in the level position,
remove the oil fill plug. Stand jack in
vertical position with hadle socket down.

shall be inspected
valve counterclockwise
of fill hole. If not, top off. Do not overfill.

oil.
4. Replace fill Plug and inspection plate.
5. Check jack operation.
6. Purge air from system as required.
System air purge:
1. Turn release valve counterclockwise one
full turn to open.
2. Pump handle eight full strokes.
3. Turn release valve clockwise to close
valve.
4. Pump Handle until the lift arm reaches
maximum heigh and continue to pump
several times to remove trapped air in the
ram.
5. Carefully and slowly pinch oil fill plug to
release trapped air.
6. Turn release valve counterclockwise one
full turn and lower lift arm to the lowest
position. Use force if necesary.
7. Turn release valve clockwise to closed
position and check for proper pump
action. it may be necessary to perform
the above more than once to assume air
is evacuated totally.
