6.8.3 Clean the cooling fins and the cooling air intake openings
WARNING!
Danger of injury!
Always wear protective clothes (goggles, gloves) when
working with compressed air.
NOTICE!
Dirty operating conditions, particularly lubrication oil
and fuel deposits on the cooling fins of the engine and
the cooling air intake opening have an adverse effect
on the cooling of the engine.
You should therefore immediately seal any oil or fuel
leaks near fuel tank, cylinder or cooling air intake.
Loosen dried on dirt with a suitable brush
cooling fins and cooling air intake openings and blow it off
with compressed air .
WARNING!
Fire hazard!
Do not use any inflammable solvents.
NOTICE!
Do not guide the water jet directly into the cooling air
openings of the recoil starter, into the air filter and on
electrical equipment.
On a oil contaminated engine use a cold cleansing agent for
cleaning.
After a sufficient soaking time clean off with a water or steam
jet and blow out with compressed air.
Run the engine warm for a while to avoid corrosion.
NOTICE!
Look for the cause of oily contamination and have any
leaks sealed by our customer service.
