MAINTNANCE
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 the internal components. The following steps are
designed to keep the jack maintained and operational.
–
Lubricate the ram, linkages, saddle and pump mechanism with light oil.
–
Visually inspect for cracked welds, bent, loose, missing parts or hydraulic oil leaks.
–
The product shall be inspected immediately if it is believed to have been subjected to
abnormal load or shock.
–
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 authorised service
representative.
–
Clean all surface and maintain all labels and warnings.
–
Check and maintain the ram oil level.
–
If necessary top up with good quality hydraulic jack oil. Do not use brake or
transmission fluids or regular motor oil as they can damage the seals.
–
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 store your jack in the fully lowered position. This will help protect critical
areas from corrosion.
6.1.
Check Oil Level
–
Turn release valve counter clockwise to allow ram to fully retract. It may be
necessary to apply force to the saddle for lowering.
–
Remove the inspection plate.
–
With the jack in the level position, remove the oil fill plug. Stand jack in vertical
position with handle socket down. The oil should be level with the bottom of the fill
hole. If not, top up. Do not overfill. Always fill with good quality hydraulic jack oil –
IS068 or Penrite.
–
Replace fill plug and inspection plate.
–
Check jack operation.
–
Purge air from system as required.
6.2.
System Air Purge
–
Turn release valve counter clockwise one full turn to open.
–
Pump handle eight full strokes.
–
Turn release valve clockwise to close valve.
–
Pump handle until the ram reaches maximum height and continue to pump several
times to remove trapped air in the ram.
–
Carefully and slowly pinch oil fill plug to release trapped air.
–
Turn release valve counter clockwise one full turn and lower ram to the lowest
position. Use reasonable force if necessary.
–
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.
