OPERATION
Raising the Ram Plunger
1. Assemble handle, ensure that spring clips align with slots.
2. Place vehicle in the 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 rm 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.
Do not use an extender on the air hose or the operating handle.
Lowering
Make certain that all personnel are clear of the load before lowering. Control the rate of descent of the
load at all times. The more you open the release valve, the faster the load descends.
1. Raise load high enough to clear the jack stands, then carefully remove jack stands (always used in pairs).
2. Slowly turn the handle counter-clockwise, but no more than 1 turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the affected jack and then the stands.
c. Lower the load by turning the release valve counter-clockwise, but no more than 1 turn.
3. After removing jack from under the load, push ram and handle sleeve down to reduce exposure to rust and
contamination.

MAINTENANCE
Important: Use only good grade hydraulic jack oil. Avoid mixing different types of uid and NEVER use brake uid,
turbine oil, transmission 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.
Adding oil
1. With ram plunger fully lowered and pump piston fully depressed, set jack in its upright, level position. Remove oil
ller plug/screw.
2. Fill with oil until just below the rim of the oil ller screw hole. Reinstall the oil ller plug/screw.
Changing oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With ram plunger fully lowered and pump piston fully depressed, remove the oil ller plug/screw.
2. Lay the jack on its side and drain the uid into a suitable container.
Note: Dispose of hydraulic oil in accordance with local regulations.
3. Fill with oil until just below the rim of the oil ller hole. Reinstall the oil ller plug/screw.
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 inline 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.
Note: Never use sandpaper or abrasive material on these surfaces!
Storage
When not in use, store the jack with pump piston and ram plunger fully retracted and air supply disconnected.
