MAINTENANCE
Important:
Use only a good grade hydraulic jack oil. Avoid mixing different types of fluid and
Never
use brake fluid,
turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause failure of the jack and the potential for
sudden and immediate loss of load. We recommend Hein-Werner hydraulic jack oil HW93291 or equivalent.
Adding oil
1. Lower saddle fully.
2. Set jack in its upright, level position.
3. Locate and remove air vent screw.
4.
Fill with oil until ~3/16" above the inner cylinder as seen from the
air vent screw
hole.
5. Reinstall the
air vent screw
.
Changing oil
For best performance and longest life, completely replace hydraulic fluid at least once a year.
1. Lower saddle fully.
2. Remove the air vent screw.
3. Lay the jack on its side and drain the fluid into a suitable container.
Note:
Dispose of hydraulic fluid in accordance with local regulations.
4. Fill with oil until ~3/16" above the inner cylinder as seen from the
air vent screw
hole.
5. Reinstall the
air vent screw
.
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that wheels,
casters and pump assemblies move freely.
Cleaning
Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
Note:
Never use sandpaper or abrasive material on these surfaces!
Storage
Lower the saddle to its lowest position when not in use.
