Service Center

2.  Piston does 

not fully 

advance and/or 

movement is 

jerky.

Low hydraulic oil level.

Check oil level. Add oil if low.

Operator

Clean or replace max. pressure valve.

Service Center

Piston gasket worn.

Replace piston gasket.

Service Center

Pump malfunction.

Repair or replace pump.

Service Center

4.  Return stroke 

incomplete.

Dirt between piston rod and 

tool.

position, disconnect AC power and 

remove any built-up dirt.

Operator

Piston return spring broken.

Replace the piston return spring.

Service Center

5.  Piston does not 

automatically 

retract.

Piston has not reached full 

extension.

Fully extend piston and check if it 

reverses.

Operator

Debris is wedged under or 

beside piston.

Manually retract piston, following the 

procedure in Section 11.2, then clean 

piston area.

Operator
