8.1 Cleaning
•
Keep all safety devices, air vents and the
motor housing free of dirt and dust as far as
possible. Wipe the equipment with a clean
cloth or blow it with compressed air at low
pressure.
•
We recommend that you clean the device
immediately each time you have finished
using it.
•
Clean the equipment regularly with a moist
cloth and some soft soap. Do not use
cleaning agents or solvents; these could at-
tack the plastic parts of the equipment. Ensu-
re that no water can seep into the device. The
ingress of water into an electric tool increases
