Headlamps, adjusting

The headlight adjustment is of great importance in
order to avoid dazzling on-coming traffic. The
headlights are of the asymmetrical type, which means
that one has to take extra care when adjusting.
Place the machine, which must not be loaded, on
level ground at right angles to a wall or similar.
Adjust the upper boundary (H) of the low beams at a
distance of (L) from the
distance (Y) between the centres of the high beams.
The distance should be the same as between the
headlamps on the machine.

Setting measurements L90E

L= 5000 mm (16 ft 4.8 in)
H = 0.85 multiplied by (1350 mm (4 ft 6.9 in) +R)
Y= 1930 mm (6 ft 4.0 in)
X= 1350 mm (4 ft 5.1 in)
R = The distance from the floor / the ground to the
centre of the front wheel hub
