8 Troubleshooting

Thermal protection
The tools are equipped with 2-stage thermal
protection:
1. * A thermo switch switches off the heater in case
of excessive interference in the air outlet of the
blow-out opening (heat accumulation). However,
the blower continues running. When the blow-out
opening is free again, the heater cuts in again
automatically after a short while. The thermo
switch can also trip after the tool is switched off. In
this case, after the tool is switched on again it
takes longer than usual until the temperature at the
blow-out opening is reached.
* does not apply to HE 20-600, H 16-500
2. The thermal fuse switches the tool off
completely in the event of overloading.
Short-term voltage drops
Switching on the machine reduces the voltage
briefly. Unfavourable mains power conditions may
have a detrimental effect on other machines.
Network impedances less than 0.4 ohms should
not cause malfunctions.
