NOTE: BEFORE USING THIS JACK, PLEASE READ THIS MANUAL, UNDERSTAND ITS OPERATING PROCEDURES, SAFETY WARNINGS AND MAINTENANCE OF THIS JACK
Carefully inspect all components for shipping damage. If shipping damage is found, notify carrier at once. The carrier is responsible for any damage resulting from shipment.

SAFETY

To avoid personal injury or property damage, please follow all safety precautions. We cannot be responsible for injury or damage resulting from unsafe and incorrect products use or system operation, or lack of maintenance.
WARNING indicates a potential danger that requires correct action to avoid personal injury.
IMPORTANT indicates correct action to prevent damage or equipment failure.

WARNING

• The hydraulic equipment operator must be qualified and familiar with correct training and work experience of hydraulic equipment. Lack of Knowledge in any of these areas can lead to equipment damage or personal injury.
• Read, understand, and follow all instructions before operating this jack.
• Inspect the jack before each use. Do not use jack if damaged, altered, modified, leaking hydraulic fluid or with missing or loose components.
• To avoid personal injury, never modify or weld hydraulic equipment.
• Never lift more than the rated capacity of the jack, overloading causes equipment failure and possible personal injury.
• The jack is a load lifting device, not a load holding device. Once the load has been positioned, it must be supported mechanically. Never work under, or around a load solely supported by hydraulic means.
• Never put unbalanced or off-center loads on the jack saddle. Do not use saddle adapters or saddle extenders between the stock lifting saddle and the load. Incorrect loading can result in equipment failure.
• Do not move or dolly the vehicle while on the jack.
• Always wear safety glasses and/or other protective equipment that meet or exceed ANSI Z87.1 and OSHA standards.
• Use the jack ONLY on hard, level surfaces capable of sustaining the load.

IMPORTANT

• Keep the hydraulic jack clean at all times.
• When the hydraulic jack is not in use, release the valve and disconnect the air hose.
• Use hydraulic equipment in normal operating temperatures. Do not use equipment in temperatures of 65°C (150°F) or higher. Over- heating will soften seals and weaken hose material, resulting in oil leaking or other equipment failure.

INSPECTION

Prior to each use, visually inspect for leaking hydraulic oil, damaged, loose or missing parts. If jack is worn or damaged remove from service and contact your nearest service center for repair.

SETUP

1. Remove the jack and handle from the package.
2. Unscrew the wheels from the jack, and assemble the handle fork between the wheels and jack body with bolts and washers.
3. Connect the red air hose in the handle to the hose coupler with red hose end, and the blue one to the coupler with blue end.
4. Open the ball valve (Part #23) by turning the knob counter-clockwise.

OPERATION

1. Verify the control level is in the neutral position.

2. Install an air filter/lubricator in the shop air line, because water in the air line will damage the jack.
   Connect shop air supply to the jack. Recommended air pressure is 100-145 psi (7-10 bar).

3. Move the control lever to UP to raise the saddle to the contact point, then move the control level to neutral position.

4. Check the placement of the jack. The load must be centered on the jack saddle. Avoid jack wheel obstructions such as gravel, tools, or uneven expansion joints.

5. Move the control lever to UP to finish lifting the vehicle.

6. Immediately place approved support stands under the vehicle’s lifting points (recommended by the vehicle manufacturer). SLOWLY and CAREFULLY lower the vehicle onto the support stands by moving the control lever to the DOWN position.

BLEEDING AIR FROM THE JACK

Air can accumulate within a hydraulic system during shipment or after prolonged use. This entrapped air causes the jack to respond slowly or feel “spongy”. To remove the air:

1. Move the control lever to DOWN position, and hold it there for a few seconds.
2. Move the control lever to UP position to complete the load-free lifting cycle.
3. Move the control lever to DOWN position to retract the jack pistons. The pistons should react in a smooth motion. If not, repeat steps 1-3.

MAINTENANCE

IMPORTANT: The greatest single cause of failure in hydraulic units is dirt. Keep the service jack clean and well lubricated to prevent foreign matter from entering the system. If the jack has been exposed to rain, snow, sand, or grit, it must be cleaned before it is used.

1. Store the jack with pistons completely retracted, in a well-protected area where it will not be exposed to corrosive vapors, abrasive dust, or any other harmful elements.

2. Use only replacement parts that are approved by the manufacturer. Disconnect the air supply before performing any maintenance operation.

3. Regularly lubricate the moving parts in the wheels, arm, and handle using a high quality grease.

4. Inspect the jack before each use. Take corrective action if any of the following problems are found:
   a. Cracked, damaged housing
   b. Excessive wear, bending, other damage
   c. Leaking hydraulic fluid
   d. Scored, damaged piston rod
   e. Loose hardware
   f. Modified equipment

5. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external surfaces of the jack.
