Notes on cleaning:
Clean the machine thoroughly each time it
has been used. Care of the machine will
protect it against damage and extend its
service life.
Remove dirt from the cooling air guide
(inlet slots) between the motor cover and
the lower housing to ensure that the motor
is adequately cooled.
Clean the mowing blade.
Clean the underside of the mower with
water and a brush. Detach accumulated
cutting deposits in the housing and in the
ejection chute beforehand using a stick.
Never spray water on motor components,
seals, bearing points or electrical
components such as batteries or switches.
This would result in expensive repairs.
If you are unable to remove the dirt with
water using a brush or a cloth, VIKING
recommends the use of a special cleaner
(e.g. STIHL special cleaner).
