Troubleshooting  

 

Check list 

6.1.1

 

The Pentpak or HF-motor doesn’t start or the feed doesn’t work 

1.

 

Check the LED’s on the Pentpak. See LED type warning lights on the power pack.  

2.

 

Check that the fuse is ok.  

3.

 

Check that the incoming voltage is not too high or low. See 4.8 Preparing the power pack.  

4.

 

Check that cables and connectors are not damaged- 

5.

 

Reset the power pack. Disconnect the power supply and wait 1 minute, re-connect power supply. Then press 

the green start button to start the power pack again. 
  

6.1.2

 

The green start button on the Pentpak is ON, no indications on the LED warning lights but the machine 

doesn’t respond to any command from the remote control.  
This is one of the few cases which cannot be indicated on the LED warning lights. If possible, try another 

remote control. The remote control needs to be checked by the authorized Pentruder service workshop. 

 

6.1.3

 

The saw stopped working 

a.

 

Please refer to the Troubleshooting Table in the Appendix for Wireless Remote Control: Hetronic User’s 

Manual.  

b.  

Check if the battery is completely run down.  

d.  

If you have a CRC cable remote control available, try using the saw with the CRC remote.  

e.  

If you have the accessory cable for the WRC wireless remote control, check if the saw works when used with 

the accessory cable.
