CHECKING THE ADJUSTMENT OF THE FRONT GRILL HEADLIGHTS
During a check on a test wall the tractor must stand on a level surface and the tyres
must be inflated to the prescribed pressure. The basic vertical setting is 3.5% at the
shipping weight of the tractor. In the horizontal direction the light beams must be par-
allel with the longitudinal axis of symmetry of the tractor.
l
- distance of the test wall from the headlight (5 m)
h
- height of the headlight centre above the road surface
Δ
h - headlight inclination (-3.5 %) to the distance of the test wall = 17.5 cm
α - raising of the outline of an asymmetrical headlight (15%)
ADJUSTING THE FRONT GRILL
HEADLIGHTS
The adjustment is performed simultane-
ously with both the screws (1) for vertical
and horizontal direction of the beam -
horizontally ± 2°; vert1° to -6°.
Each headlight is adjusted separately.
The lamps are replaced by removing
from the rear side of the reflector. Due
to the confined space release and move
or completely remove the starting bat-
tery.
