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 qualified personnel.

PREPARATION
Before Use
1. Verify that the product and application are compatible, if in doubt call Atd Tools Technical Service (636) 327-
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, use the stamped end of the provided handle to engage and turn release valve:
a. Clockwise until firm 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 filler plug. Pump 6 to 8 full strokes. Check oil level. *Proper oil level will vary from just covering the ram cylinder to 3/16” above it as seen from the oil filler hole. Reinstall the oil filler plug.
*NOTICE: If the oil level is too low, the jack will not raise to its advertised maximum height. DO NOT overfill the reservoir. An overfilled reservoir can cause a wide variety of performance problems and create an oily mess on the shop floor! See the troubleshooting guide on page 4.
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 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 filler plug. Pump 6 to 8 full strokes. This will help release any pressurized air which may be trapped within the reservoir.
Reinstall the oil filler plug.

WARNING
X
To avoid crushing and related injuries:
• Never work on, under or around a load supported only by hydraulic jack.
• Always use 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 influence of drugs or alcohol.
OPERATION
Lifting
!
Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on area of the vehicle as specified 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. Close release valve by turning it with the stamped end of handle clockwise until firm 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.
!
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.
Lowering
!
Be sure all tools and personnel are clear before lowering load. Slowly open the release valve!
The more 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!
1. Raise load high enough to clear the jack stands.
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.
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.

MAInTenAnCe
Important: Use only good grade 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. We recommend Mobil DTE 13M or equivalent.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Remove oil filler plug.
2. *Proper oil level will vary from just covering the inner cylinder to ~3/16” above the inner cylinder as seen from the oil filler plug hole. Reinstall the oil filler plug.
*NOTICE: If the oil level is too low, the jack will not raise to its advertised maximum height. DO NOT overfill the reservoir. An overfilled reservoir can cause a wide variety of performance problems and create an oily mess on the shop floor! See the troubleshooting guide below.
Changing oil
For best performance and longest life, replace the complete fluid supply at least once per year.
1. With saddle fully lowered, remove the oil filler plug.
2. Lay the jack on its side and drain the fluid into a suitable container.
note. Dispose of hydraulic fluid in accordance with local regulations.
3. *Fill with oil until ~3/16" above the inner cylinder as seen from the oil filler hole. Reinstall oil filler 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.
TROUBLeSHOOTInG
