Replacing the Dust Protection Cap
Damaged
dust protection caps should be replaced as possible since dust that enters the tool holder can
cause malfunctions.
Pull back and hold the locking sleeve pull off the dust cap with a suitable tool.
With the locking sleeve pulled back, pull on the new dust cap until it sits firmly over the tool holder and the
locking sleeve can again be slid forward.
If the machine should happen to fail despite the care taken in manufacture and testing, repair should be
carried out by an authorised customer services agent for Maxpro power tools.
