Cleaning And Maintance - MaxPro PROFESSIONAL MPRH900/26V Bedienungsanleitung

CLEANING AND MAINTANCE

Before any work on the machine itself, pull the mains plug.
For safe and proper working, always keep the machine and the ventilation slots clean.
Clean the tool mount daily.
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.
