14.2 Cleaning the machine

Avoid damage to the machine!
Never spray water (high-pressure
cleaner) onto engine components,
seals, electrical components
(battery, wiring harness, etc.) and
bearing points. This may result in
damage and expensive repairs.
Do not use aggressive cleaning
agents. These cleaners can
damage plastics and metals,
impairing the safe operation of your
STIHL machine. If you are unable
to remove the dirt with water using
a brush or a cloth, STIHL
recommends the use of a special
cleaner (e.g. STIHL special
