MAINTENANCE
Important: Useonly agood gradehydraulic jackoil.Avoid mixingdifferent typesof fluidandNever usebrake fluid,turbine
oil, transmission fluid, motor oil or glycerin. Improper fluid can cause failure of the jack and the potential for sudden and
immediateloss of load.We recommendHein-Werner hydraulic jack oil HW93291.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Locate and unscrew air vent screw.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the air vent screw hole. Reinstall the air vent screw.
Changing oil
Forbest performance,replacethe hydraulic fluidcompletely annually.
1.With saddle fullylowered, unscrewthe air vent screw.
2. Lay the jack on its side and drain the fluid into a suitable container.
Note: Disposeof hydraulic fluidin accordancewith localregulations.
3. Fill with oil until ~3/16" above the inner cylinder as seen from the air vent screw hole. Reinstall the air vent screw.
Lubrication
Aperiodic coating oflight lubricatingoil to pivot points, axlesand hingeswill help to prevent rustand assure
thatwheels, castersand pumpassemblies movefreely.
Cleaning
Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
Note: Neverusesandpaperor abrasivematerialonthesesurfaces!
Storage
Lower the saddle to its lowest position when not in use.
