Maintenance
This section describes how to maintain your Jack.
To maintain your Jack:
•
Storing. Store your Jack in the fully lowered position; this protects the Jack from corrosion.
•
Daily. Keep the Jack clean. Dirt, rust, and so on can cause slow movement or rapid jerks, both of
which damage internal components. Make sure all labels are in place and visible.
•
Weekly. Inspect the Jack for cracked welds, hydraulic fluid leaks, missing or damaged parts.
•
Monthly. Lubricate the Jack with light oil.
•
Monthly. Check the hydraulic fluid level. Fill as necessary.
•
Every three months. Fully clean and lubricate the Jack.
To purge air from the hydraulic system:
1. Turn the Handle Grip counterclockwise; lower the Lifting Arm to the ground.
2. Pump the Handle eight full strokes.
3. Turn the Handle Grip clockwise.
4. Pump the Handle until the Lifting Arm reaches maximum height; pump several times more to
remove any trapped air.
5. Carefully pinch the fluid fill plug to release trapped air.
6. Turn the Handle Grip counterclockwise; lower the Lifting Arm to the ground. Use force if needed.
7. Turn the Handle Grip clockwise; check for proper pump action.
It may be necessary to perform this procedure more than once to purge all of the air.
To check hydraulic fluid levels:
1. Turn the Handle Grip counterclockwise to fully lower the Jack. You may need to push it down.
2. Remove the fluid fill plug.
3. Stand Jack in vertical position with Handle down.
The hydraulic fluid should be level with the bottom of fill hole. If not, top it off . Do not overfill. Only
add new, clean hydraulic fluid.
4. Replace the fluid fill plug.
