PRODUCT DESCRIPTION
Hein-Werner Hydraulic Service Jacks are designed to lift, not support, rated capacity loads consisting of one end of a
vehicle. Immediately after lifting, the load must be supported by a pair of appropriately rated jack stands.
Never use hydraulic jack as a stand alone device. After lifting, immediately
support the lifted load with a pair of appropriately rated jack stands.

PREPARATION (REFER TO FIGURE 1)
Before Use
1. Verify that the product and application are compatible, if in doubt call Hein-Werner technical service.
2. Before use, read the operator's manual completely and familiarize yourself thoroughly with the product, its components
and recognize the potential hazards associated with its use.
3. Insert handle to handle fork. Tighten the bolt on handle fork to prevent accidental removal of handle while in use.
4. To familiarize yourself with the basic operation of these jacks, locate and turn the release valve (handle):
a. Clockwise until rm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used to
raise the load.
b. Counter-clockwise, but no more than 1/2 full turn from the closed position. This is the ‘OPEN’ release valve
position used to lower the load.
5. With saddle fully lowered, locate and remove air vent screw. Pump the operating handle through 6 to 8 full strokes.
Check the oil level. Ensure the oil level is within ~3/16" from the inner cylinder as viewed from the air vent screw
hole.
6. Reinstall the air vent screw.
7. Check to ensure that the jack rolls freely. Raise and lower the unloaded saddle throughout the lift range before
putting into service to ensure the pump and release valve operate smoothly.
8. Replace worn or damaged parts and assemblies with Hein-Werner Replacement Parts only. Lubricate as instructed
in Maintenance Section.

OPERATION
Lifting
Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on areas of the
 vehicleasspeciedbythevehiclemanufacturer.
1. Follow the vehicle manufacturer’s recommended guidelines for lifting. Engage the emergency brake and chock each
unlifted wheel in both directions to prevent inadvertent vehicle movement.
2. Locate and close the release valve by turning the handle clockwise until rm resistance is felt.
3. Refer to the vehicle manufacturer owner’s manual to locate approved lifting points on the vehicle. Center jack saddle
under lift point.
4. Verify lift point then use handle pump to contact lift point. To lift, pump handle until load reaches desired height.
5. Transfer the load immediately to appropriately rated jack stands.
NEVER use hydraulic jack as a stand alone device! ALWAYS transfer the lifted load IMMEDIATELY to a
pair of appropriately rated jack stands. Use one pair of jack stands per vehicle. Rated capacity is per pair
only! Do not exceed rated capacity.
Overloading may cause hydraulic system failure.
Lowering
Be sure all tools and personnel are clear before lowering load. Slowly open the release valve! The more
you turn the release valve (handle) counter-clockwise, the faster the load will come down. Maintain control
of the rate of speed at which the load lowers at all times!
1. Raise load high enough to clear the jack stands.
2. Remove jack stands, carefully. (always used in pairs).
3. Slowly turn the release valve (handle) counter-clockwise, but no more than 1/2 full turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the malfunctioning jack and then the jack stands.
c. Using the functioning jack, lower the load by turning the operating handle counter-clockwise, but no more than
1/2 full turn.
4. After removing jack from under the load, push saddle down to reduce ram exposure to rust and contamination.

TROUBLESHOOTING

MAINTENANCE
Important: Use only a 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 failure of the jack and the potential for
sudden and immediate loss of load. We recommend Hein-Werner hydraulic jack oil HW93291 or equivalent.
Adding oil
1. Lower saddle fully.
2. Set jack in its upright, level position.
3. Locate and remove air vent screw.
4. Fill with oil until ~3/16" above the inner cylinder as seen from the air vent screw hole.
5. Reinstall the air vent screw.
Changing oil
For best performance and longest life, completely replace hydraulic uid at least once a year.
1. Lower saddle fully.
2. Remove the air vent screw.
3. Lay the jack on its side and drain the uid into a suitable container.
Note: Dispose of hydraulic uid in accordance with local regulations.
4. Fill with oil until ~3/16" above the inner cylinder as seen from the air vent screw hole.
5. Reinstall the air vent screw.
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 pump piston and 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
Lower the saddle to its lowest position when not in use.
REPLACEMENT PARTS (refer to page 6 & 7)
