 Danger of accidents! Switch off the engine before installing or
removing the fan grille.

This can be tipped back together with the fan for easier cleaning
of the radiator fins.
1. Unscrew the four screws (1) and remove the radiator guard.
2. Unscrew both screws (2) to flip out the fan grille (approx. 45°)
and clean the radiator fins.
3. Reinstall the fan grille after cleaning.

4. Install the radiator guard.
V-belt – check condition
Check the v-belt of the alternator and the air conditioner (optional)
for cracks.
 If a vertical crack (2) is apparent which intersects with a hori-
zontal crack (1).
 If a part of the belt is broken (3).
There is no need for a renewal if only a horizontal crack (4) is
detected.
