Maintenance work
8.2 Cleaning the protective hood
With time, material deposits will form on the inside of the protective
hood (particularly when wet cutting). Under certain circumstances,
these deposits can hinder the free rotation of the cutting blade.
Detach the cutting blade and thrust washer and remove the material
deposits on the inside with a wood strip or similar tool.
Wipe off the shaft and all disassembled parts with a clean cloth.
8.3 Cleaning/Changing the air cleaner
NOTICE:
Before cleaning the air cleaner, turn off the engine! Never clean the air
cleaner with compressed air! Do not clean the prefilter or the internal
filter with fuel!
The engine's service life depends on the condition and the regular
maintenance of the filter elements. Not regularly cleaning or maintain-
ing the engine leads to excessive wear!
Replace a damaged air cleaner immediately! Torn pieces of fabric and
large dirt particles can destroy the engine. If possible, do not work in
dusty conditions! The particulate matter generated when dry cutting
concrete and stone endangers the operator's health and shortens the
engine's service life. If possible, carry out cutting operations for con-
crete and stone with water to bind dust particles together.
