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.
Adding oil
1 .
With saddle fully lowered and jack
in its upright, level position, remove oil filler
plug. It may be necessary to remove cover
plate on same models.
2.
Fill until oil is level with the filler plug
hole, reinstall oil filler plug and cover plate.
Changing
oil
For best performance and longest life,
replace the complete fluid supply at least
once per year.
3.
With saddle fully lowered, remove
the oil filler plug. It may be necessary to
remove cover plate on some models.
1.
Lay the jack on its side and drain
the fluid into suitable container.
Note:
Dispose
of
hydraulic
fluid
in
accordance with local regulations.
2.Fill with good quality jack oil. We
recommend Mobile ~DTE 13 or equivalent.
Reinstall oil filler plug and cover plate.
Lubrication
1 .
A 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.
2.
Periodically check the pump piston
and ram for signs of rust or corrosion.
Clean as needed and wipe with an oily
cloth.
NEVER USE SANDPAPER OR ABRASIVE
MATERIAL ON THESE SURFACES!
