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 qualied personnel.
Labels and Operator's Manuals are available from manufacturer.
PRODUCT DESCRIPTION
Hydraulic Service Jack is designed to lift, but not support, one end of a vehicle. Immediately after lifting, loads must
be supported by a pair of appropriately rated jack stands.
NEVER use hydraulic jack as stand-alone device. After lifting, immediately support the lifted vehicle with
!
a pair of appropriately rated jack stands.
PREPARATION
Assembly
1. Assemble the 2-piece handle with provided bolt.
2. Insert handle into the handle fork. Tighten the bolt on handle fork to prevent accidental removal of handle while
in use.
Before Use
1.
Verify that the product and application are compatible,
9050.
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, 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 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, remove the oil ller plug. 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 plug.
5. 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 ATD Tools
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
plug. Pump 6 to 8 full strokes. This will help release any pressurized air which may be trapped within the reservoir.
Reinstall the oil ller plug.

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.
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 pump handle to contact lift point. To lift, pump handle until load reaches desired height.
5. Transfer the load immediately to appropriately rated jack stands.
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
you turn the 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!
NEVER use hydraulic jack as a stand alone

2.
Remove jack stands carefully (always used in pairs).
3. Slowly turn the 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.

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 saddle fully lowered set jack in its upright, level position. Remove oil ller plug.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall the oil ller plug.
Changing oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With saddle fully lowered, remove the oil ller plug.
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 oil ller plug.
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
When not in use, store the jack with saddle fully lowered.
