8. Cleaning
It is possible that particles deposit inside the power
tool during operation. This impairs the cooling of the
power tool. Conductive build-up can impair the
protective insulation of the power tool and cause
electrical hazards.
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner. Prior to this operation,
separate the power tool from the power source and
wear protective glasses and dust mask.

9. Troubleshooting

The electronic signal display lights up
and the load speed decreases (not

machine! Run the machine in idling until the
electronics signal indicator switches off.
Machines with VTC, TC and VC electronics:
