OPERATION
Raising the Ram Plunger
1. Assemble handle, ensure that spring clips align
with slots.
2. Place vehicle in park, with emergency brake on
and wheel securely chocked to prevent inadvertent
vehicle movement.
3. Locate and close release valve by turning handle
clockwise until firm resistance is felt to further
thread engagement.
4. Verify lift point, center jack saddle under lift point.
5. Squeeze the lift control valve or insert handle into
handle sleeve and pump to contact lift point. To lift,
continue pumping until load reaches desired height.
DO NOT OPERATE BY AIR AND BY HAND PUMPING
AT THE SAME TIME.
6.
Immediately
transfer the lifted load to a pair of
appropriately rated jack stands.
NOTICE:
Use the provided Pump Handle. The handle
furnished with this jack will safely engage the release
valve and operate the Handle Sleeve. If handle is worn,
operates abnormally, or will not positively engage the
release valve, STOP, discontinue use of the jack until
a factory replacement handle can be acquired.
NOTICE:
Do not use extensions on air hose or
operating handle.
Lowering
WARNING:
Clear all tools and personnel before
lowering load. Open release valve slowly. The further
handle is turned counter-clockwise, the faster the load
will descend. Maintain control of the load at all times.
1. Raise load high enough to clear the jack stands, then
remove jack stands.
2. Slowly turn the handle counter-clockwise, but no more
than 1/2 turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough
to reinstall jack stands.
b. Raise load high enough to clear the jack stands,
remove the affected jack and then the stands.
c. Lower the load.
3. After removing jack from under the load, push ram
and handle sleeve down to reduce exposure to rust
and contamination.
MAINTENANCE
NOTICE:
Use only good quality 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 is recommended.
Adding oil
1. With ram plunger fully lowered and pump piston
fully depressed, set jack in its upright, level position.
Remove oil filler screw.
2.
Fill with oil until just below the rim of the oil filler plug
hole. Reinstall the oil filler screw.
Changing oil
For best performance and longest life, replace the
complete fluid supply at least once per year.
1. With ram plunger fully lowered and pump piston fully
depressed, remove the oil filler screw.
2. Lay the jack on its side and drain the fluid into a
suitable container.
NOTICE:
Dispose of hydraulic oil in accordance with
local environmental regulations.
3.
Fill with oil until just below the rim of the oil filler hole.
Reinstall the oil filler screw.
4. Perform
Bleeding/Venting Trapped Air
procedure,
pg. 2.
Lubrication
1. A periodic coating of light lubricating oil to pivot
points will help to prevent rust and assure that pump
assemblies move freely.
2. Air pump should be internally lubricated before each
use. Use good quality air tool lubricant. If no in-line
oiler is used, pour a teaspoon of air tool oil into the air
control valve inlet. Operate the jack with air pressure
to fully distribute the oil inside the air motor.
Cleaning
Periodically check the pump piston and ram for signs of
rust/corrosion. Clean as needed and wipe with oily cloth.
NOTICE:
Do not use sandpaper or abrasive material
on ram and pump piston surfaces.
Storage
When not in use, store the jack with pump piston and
ram plunger fully retracted and air supply disconnected.
