How to replace the motor brushes
After approximately 50 hours of work time with the rotary tool, the 2 brushes in
the motor will wear out. Since the brushes are carbon blocks that conduct
electricity from the mains power into the motor and are therefore essential for the
motor to work, worn-out brushes will cause the rotary tool to stop working. But no
worries - it's an easy fix, and we've included 2 spares in the kit.

Open the motor brush housing caps on the sides of the rotary tool with the
included screwdriver. You can see the location of the motor brush housing caps
on page 12, while a picture of the screwdriver/wrench can be found on page 23.
Take the old motor brushes out, and place the new ones in with the carbon
block going in first. Be careful to not damage the spring!
Put the motor brush housing caps back on with the circular end of the spring
against the cap, and tighten with the screwdriver.
CLEANING AND MAINTENANCE
Cleaning
Before starting to clean your precious rotary tool, always disconnect it from the
mains power plug first. The cleaning itself is a pretty simple affair - wipe the
equipment with a clean cloth or blow it with compressed air at low pressure. For
more stubborn stains, use a lightly damp cloth with some soft soap, but make sure
that no water can seep inside your rotary tool (that includes not using wet
attachments & accessories).
NB!
Do not use cleaning agents or solvents, as they may damage the plastic parts.
In between cleanings, try to keep all safety devices, air vents and the motor
housing as far away from dirt and dust as possible.
