Replacing the carbon brushes
The hammer drill uses carbon brushes, which
wear down. Therefore check them regularly
and replace both of them when one or both
are worn down to the wear limit, which is 5
mm.
1. Disconnect the hammer drill from the
mains. Remove the black plastic section
(b). Take the hammer drill apart by
unscrewing the screws in all the screw
holes (a) and removing the top of the
casing (c).
2. Lift out the brush holders (d) and remove
the worn brushes (e). Insert a new brush
in the brush holders and connect the
cord with the copper plate (f ) to the
spring. Replace the brush holders.
3. Replace the casing and the plastic
section and check that the hammer drill
is correctly assembled before using it
again.
