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 parallel with the longitudinal axis of symmetry of the tractor.
Adjusting the front grill headlights
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

The adjustment is performed simultaneously with all the
screws for the vertical and horizontal direction of the
beam. In the adjusted condition all the springs of non-
adjusting screws must be pre-tensioned. Each headlight is
adjusted separately. The lamps are replaced by removing
from the rear side of the reflector.
