MAINTENANCE:
1. Both the maintenance and repair of the jack may only be performed
by qualified professionals.
2. Only original spare parts should be used.
3. When not in use, store the jack with saddle fully lowered.Keep the
jack in a clean, dry place and keep out of reach of children .
4. If the oil level needs to be checked or refilled, remove the filler plug
and drain contents into a container. Make sure that no dirt enters with
the new oil.
5. Too much oil will prevent saddle from lowering completely. Not
enough oil and saddle will not be able to rise to full height.
6. Do not 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 is recommended.
