Maintenance interval:
After each use
Clean the machine thoroughly each time it
has been used. Care of the machine will
protect it against damage and extend its
service life.
Never spray water onto
motor or engine components,
seals, bearing points or
electrical parts such as
switches. This would result in
expensive repairs.
If you are unable to remove
the dirt and accumulated
deposits with a brush, a damp
cloth or a stick, VIKING
recommends the use of a
special cleaner (e.g. STIHL special
cleaner).
Do not use aggressive cleaning agents.
Clean the blade discs regularly.
Remove dirt from the cooling ribs, fan
wheel, area around the air filter, exhaust,
etc. to ensure that the engine is
adequately cooled.
