LIGHTS ADJUSTMENT IN TRACTOR´S
GRILL
Adjustment is done simultaneously with
all screws for both vertical and horizontal
direction of a beam. In adjusted state all
the springs of unadjusted screws must
be preloaded! Each headlight is adjusted
separately. Bulb replacement is done by
removing it from the back side of reflec-
tor.
