MAINTENANCE AND STORAGE
Lubricating
All moving parts on jack should be lubricated every month with a general purpose grease to maintain
efficient operation. Apply grease to joints on lift arm hinges, push rods; handle base, rear caster
wheels, front roller, etc. Lifting arm pivot point #37 needs to be well lubricated or jack may make
creaking sounds under heavy loads.
Maintaining Oil Level
Important Note:
When adding or replacing oil, always use SAE 10 Hydraulic Jack Oil. Avoid mixing types of oil. DO NOT use
Brake Fluid, Alcohol, Glycerin, Detergent, Motor Oil or Dirty Oil, Improper fluid can cause serious internal
damage to Jack.
Adding Oil:
With head cap fully lowered & jack on level ground, remove Air Vent Valve. Oil level should be visible at the
air vent valve hole approx 12 mm below valve hole, do not overfill. If low, add oil as needed then close air vent
valve.
Replacing Oil:
For better performance & longevity, replace oil supply once a year. To drain oil, open Air Vent Valve and
loosen the release Valve by turning handle counter clockwise. BE VERY CAREFUL not to permit dirt or
foreign matter to get into the system. Invert jack over suitable container and allow oil to drain. Close
release valve by turning handle clockwise, fill with SAE 10 Hydraulic Jack Oil close Air Vent Valve wipe away
any spilt fluid. Test jack before lifting a load.
Hydraulic Trouble Shooting
Guide to purging air from the hydraulic system of a trolley jack. During shipping
or handling or if stored other than level air may become trapped in the hydraulic
system of a jack. If jack does not provide a full stroke or ram feels spongy, it will
be necessary to purge air out of the hydraulic system. To do this please follow
there instructions. Open the release valve fully from its closed position, 2 full turn
only. Pump the jack handle 20 full strokes with the valve open, this will purge air.
Repeat as necessary.
Cleaning
Jack should be wiped clean with soft cloth only. Do not use gasoline, kerosene, or other such solvents or any
abrasive cleanser as cleaning agents and solvents will cause deterioration of the hydraulic seals.
