TROUBLESHOOTING
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 premature failure of the jack
and the potential for sudden and immediate loss of load.
We recommend Mobil DTE 13M or equivalent. Reinstall
oil filler plug/ screw.
Adding oil
1. With saddle fully lowered, set jack in its upright,
level position. Remove oil filler plug/ screw.
2. Fill until oil is level with the oil filler hole, reinstall oil
filler plug/ screw.
Changing oil
For best performance and longest life, replace the
complete fluid supply at least once a year.
1. With saddle fully lowered, set jack in its upright,
level position. Remove the oil filler plug/ screw.
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 upright position.
4. Fill with good quality jack oil.
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 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 pump piston and
saddle in lowest position.
