MAINTENANCE
Important:
Use only good grade hydraulic jack oil. Avoid
mixing di eren
and
NEVER
turbine oil, transmis
uid, motor oil or glycerin. Improper
uid can cause premature failure of the jack and the potential
for sudden and immediate loss of load. We recommend
Mobil DTE 13M or equivalent.
On air actuated model
, periodically check for leaks at
air connections. Replace connections as needed.
Adding oil:
1. With saddle fully lowered, set jack in its upright, level
position. Remove oil
screw.
2.
Changing oil:
For best performance and longest life, replace the complete
st once per year.
1. With saddle fully lowered, set jack in its upright, level
position. Remove the oil ller screw.
2. Lay the jack on its side and drain the uid into a suitable
container.
Note:
Dispose of hydraulic
in accordance with local
regulations.
3.
4. Reinstall the oil
screw.
Lubrication:
1. 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.
2. When used on a daily basis, air pump model should be
internally lubricated before each use. Use only good
quality air tool lubricant. If no inline oiler is used, pour a
teaspoon of air tool oil into the inlet of the air supply
inlet. Simply operate the jack using the air feature in
order to fully distribute the oil.
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 saddle in lowest
position and air supply disconnected.
REPLACEMENT PARTS:
Not all components of the jack are replacement items, but
are illustrated as a convenient reference of location and
position in the assembly sequence. When ordering parts,
give part number and the description on page 6 & 7. Call
your distributor for current pricing.
