Lubrication - SFA 41100C Manuel Des Consignes D'utilisation Et Des Pièces

MAINTENANCE
Important: Use only premium 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 premature failure of the jack and
the potential for sudden and immediate loss of load. Premium hydraulic jack oil or equivalent recommended.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil filler hole. Reinstall oil filler plug.
Changing oil
For best performance and longest life, replace the complete fluid supply at least once per year.
1. With saddle fully lowered, remove oil filler plug.
2. Lay the jack on its side and drain the fluid into a suitable container.
Note. Dispose of hydraulic fluid in accordance with local regulations.
3. Set jack in its level position.
oil filler plug.
4. Perform Bleeding/Venting Trapped Air procedure.

Lubrication

A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
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
When not in use, store the jack with saddle fully lowered.
