SAFETY and GENERAL INFORMATION
Save these instructions. For your safety, read, understand, and follow the information provided with and on this jack
before using. The owner and operator of this equipment shall have an understanding of this jack and safe operating
procedures before attempting to use. The owner and operator shall be aware that use and repair of this product
may require special skills and knowledge. Instructions and safety information shall be conveyed in the operator's
native language before use of this jack is authorized. If any doubt exists as to the safe and proper use of this jack,
remove from service immediately.
Inspect before each use. Do not use if broken, bent, cracked or damaged parts are noted. Any jack that appears
damaged in any way, or operates abnormally shall be removed from service immediately. If the jack has been or
suspected to have been subjected to a shock load (a load dropped suddenly, unexpectedly upon it), immediately
discontinue use until jack has been checked by a factory authorized service center (contact distributor or manufacturer
for list of authorized service centers). It is recommended that an annual inspection be done by qualied personnel.
Labels and Operator's Manuals are available from manufacturer.
PRODUCT DESCRIPTION
Long Chassis Service Jack is designed to lift, but not support, one end of a vehicle. Immediately after lifting, loads
must be supported by a matched pair of appropriately rated jack stands. Air actuated unit requires at least 7.8 CFM
@ 110 - 175 PSI. A minimum of 150 PSI air pressure is required to raise rated capacity load.
NEVER use hydraulic jack as stand-alone device. After lifting, immediately support the lifted vehicle with
a matched pair of appropriately rated jack stands.

PREPARATION
Assembly
Always secure the handle into the handle sleeve by means of the bolt lock washer and nut provided. Tighten securely
to prevent accidental removal of handle while in use.
Before Use
1. Verify that the product and application are compatible.
2. Before using this product, read the operator's manual completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards associated with its use.
3. To familiarize yourself with basic operation, turn the release valve (handle knob):
a. Clockwise until rm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used to
raise the saddle.
b. Counter-clockwise, but no more than 1/2 turn from the closed position. This is the ‘OPEN’ release valve
position used to lower the saddle.
4. With saddle fully lowered, locate and remove cover plate, then remove the oil ller screw. Pump 6 to 8 full strokes.
This will help release any pressurized air which may be trapped within the reservoir. Check oil level. Proper oil
level will vary from just covering the ram cylinder to 3/16” above it as seen from the oil ller hole. Reinstall the oil
ller screw.
5. Pour a teaspoon of good quality, air tool lubricant into the air supply inlet of the lift control valve. Connect to air
supply and operate for 3 seconds to evenly distribute lubricant.
Note: This is equipped with the popular 1/4" NPT air coupler. When installing a different air coupler of your choice,
ensure that thread tape or compound is used when servicing connections. To ensure dependable, trouble free
operation an inline air dryer and oiler is recommended.
6. Ensure that jack rolls freely. Raise and lower the unloaded saddle throughout the lifting range before putting into
service to ensure the pump operates smoothly. Replace worn or damaged parts and assemblies with factory
authorized replacement parts only.
Bleeding / Venting Trapped Air
With the release valve in the OPEN position (3b.) and with saddle fully lowered, locate and remove the oil ller
screw. Pump 6 to 8 full strokes. This will help release any pressurized air which may be trapped within the reservoir.
Reinstall the oil ller screw.
• Study, understand, and follow all printed
materials provided with/on this product before use.
• Do not exceed rated capacity.
• Use only on hard, level surface capable of
supporting the load.
• This is a lifting device only!
• Immediately after lifting, support the load with
a matched pair of appropriately rated jack
stands.
• Lift only on areas of the vehicle as specied by
the vehicle manufacturer.
• Never wire, clamp or otherwise disable the lift
control valve to function by other than operator's
hand.
•
Do not move or dolly the vehicle while on the jack.
• No alterations shall be made to this product.
• Failure to heed these markings may result in
personal injury and/or property damage.
To avoid crushing and related injuries:
• Never work on, under or around a load supported
only by hydraulic jack.
• Always use a matched pair of adequately rated
jack stands.
• Chock each unlifted tire in both directions.
• Do not use this device to lift, level, lower, support nor
move a house, mobile home, travel trailer, camper or
any building structure.
• Be alert and sober when using this product. Do not
operate under the inuence of drugs or alcohol.

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 failure of the jack and the potential for
sudden and immediate loss of load.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil ller screw.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall the oil ller screw.
Changing oil
For best performance, replace the complete uid supply at least once per year.
1. With saddle fully lowered, remove the oil ller screw.
2. Lay the jack on its side and drain the uid into a suitable container.
Note: Dispose of hydraulic uid in accordance with local regulations.
3. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall the oil ller screw.
!
OPERATION
Lifting
Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on area of the
 vehicleasspeciedbythevehiclemanufacturer.
Note: The jack is equipped with handle position lock. To adjust the handle, release lock device by pulling the lever
up, then back until lever is locked into place.
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 release valve knob 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 pump handle or foot pedal to contact lift point. To lift, pump handle or squeeze lift control valve
until load reaches desired height. Never use foot pedal to raise load.
5. Transfer the load immediately to a matched pair of appropriately rated jack stands.
NEVER use hydraulic jack as a stand alone device! ALWAYS transfer the lifted load IMMEDIATELY to a
matched 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.
Lowering
Be sure all tools and personnel are clear before lowering load. Slowly open the release valve! The more
you turn the release valve knob 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 matched pairs).
3. Slowly turn the release valve knob 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. Use the functioning jack to lower the vehicle.
4. After removing jack from under the vehicle, fully lower the saddle to reduce ram exposure to rust and
contamination.

escape. Reinstall oil ller screw
Will not lift to full extension • Fluid level low • Ensure proper uid level
MAINTENANCE
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. To help ensure trouble free operation, an inline air dryer and
oiler is recommended.
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
When not in use, store the jack with saddle fully lowered.
