MAINTENANCE
Operation
1. Verify the control lever is in the neutral position.
2. Connect shop air supply to the jack. Recommend air pressure is 0.7 to 1bar. Install an air fi lter/lubricator in the
shop air line, because water in the air line will damage the jack. Oiler sold in retail (ref SA 6206).
3. Move the control lever to the right to raise the saddle to the contact point. Move the control lever 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 the right fi nish 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 pushing the control lever to the DOWN
position.
Bleeding air
Air can accumulate within a hydraulic system during shipment or after prolonged use. This entrapped air causes
the jack to respond slowly or fell "spongy". To remove the air:
1. Move the control lever to the left, and hold it there for a few seconds.
2. Move the controle lever to the right to complete a load-free lifting cycle.
3. Move the control lever to the left to retract the jack pistons. The pistons should react in a smooth motion. If not,
repeat steps 1-3.
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. Regulary lubricate the moving parts in the wheels, arm, and handle using a hight quality grease.
4. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. cracked, damaged housing
d. scored, damaged piston rod
b. excessive wear, bending, other damage
e. loose hardware
c. leaking hydraulic fl uid
f. modifi ed equipment
5. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external
surfaces of the jack.
