TROUBLESHOOTING

Troubleshooting schedule

Following the trouble shooting guide will provide you with tips to facilitate the trouble shooting process. You can also 
perform simpler trouble shooting operations. The operator may only carry out the maintenance and service operations 
that are described in this Operator’s Manual. More extensive interventions must be carried out by an authorized service 
workshop.

Always start by checking any error messages on the remote control. Follow the instructions for the respective message 
in accordance with the error messages section.

!

WARNING! Most accidents involving machines occur during trouble shooting, service and 
maintenance as staff have to locate themselves within the machine’s risk area. Prevent accidents 
by being alert and by planning and preparing the work. You can also refer to 'Preparations for 
maintenance and service” in the 'Maintenance and service” section.

If service operations or trouble shooting does not require the machine to be switched on, the 
power cable must be removed and positioned so that it cannot be connected by mistake.

Problem

Cause

Possible action

The electric motor does not 
start.

Emergency stop/machine stop is 
pressed.

Check that the emergency stop or machine stop button 
are not pressed by turning them clockwise.

Too low mains voltage to the machine.

Check power supply and ensure correct voltage.

A fuse has blown.

Check that the mains voltage is compatible with the 
machine and that the correct fuses are used.

Check the power cable.

No radio communication between 
remote control and machine.

Green symbol in the display indicates contact. If the 
symbol is red, check that the battery for the remote 
control is charged and correctly inserted. Ensure that 
the correct remote control is being used. Check that 
the communication cable and aerial cable on the 
machine are properly secured. Test run the machine 
using cable control.

Fuses for the mains 
connection blow when 
starting.

The machine’s fuses have too low a 
rating.

Check that the mains voltage is compatible with the 
machine and that the correct fuses are used.

Electric motor blown.

Contact your service agent.

Defective power cable.

Change the power cable.

The hydraulic pump has cut out.

Contact your service agent.

The motor runs but the 
hydraulic functions have no 
power or do not work at all.

Too little hydraulic fluid in the tank. 
(Noise emanating from the pump.)

Stop the motor at once. Investigate and rectify any 
leaks there might be. Replenish hydraulic fluid.

Circulation valve open.

Check the diode on the valve cap at the bottom of 
valve block 1. If the circulation valve is open the diode 
does not light up. Check the cable to the control 
module.

Fault in the pump regulator.

Extend an unloaded cylinder to its end position and 
check the pump pressure in the display. If you get 
maximum pressure the pump regulator is OK.

Standby pressure set too low.

Activate the remote control without operating any 
functions and check the settings for stand-by pressure 
on the display. The pressure should be 20 

±

 1 bar.

Arm movements and tool 
function run slowly.

The potentiometer that controls 
mechanical movements/tools is 
screwed down.

Unscrew the knob(s).

Standby pressure set too low.

Activate the remote control without operating any 
functions and check the settings for stand-by pressure 
on the display. The pressure should be 20 

±

 1 bar.
