2. Adjust the amount of oil.

3. Replace the pump.

Nothing works

1. Emergency stop is activ-

ated

2. Fuse/relay blown

and restart.

2. Replace the fuse/relay

Noise from cylinders

Jerky hydraulic move-

5. Service or replace the

pump.

6. Replace the filter.

Poor lifting capacity

1. Insufficient amount of oil

to the pump

2. Oil pressure too low.

3. Leaking cylinder gas-

kets.

1. Check the oil level.

2. Contact JOAB.

3. Replace the cylinder gas-
