cooler
Danger
!
Danger of injury!
Cleaning work should only be carried out with
the engine stopped and cooled down.
Caution
!
Take care to avoid deformation of the radiator
cooling fins.
i Note
Dirt on blower wings and oil cooler reduces the
cooling efficiency. Dampness caused by oil and
fuel on these surfaces support the accumulation of
dirt in these areas. You should therefore eliminate
any oil or fuel leaks in these areas immediately
and clean the cooling surfaces after.
