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.
Do not dispose of electric tools, accessories and packaging together with household waste material
- in observance of European Directive 2002/96/EC on waste of electric and electronic equipment and its
implementation in accordance with national law, electric tools that have reached the end of their life
must be collected separately and returned to an environmentally compatible recycling facility
