4.2
Setting up
1. Move the beamsetter into
position in front of the
headlamp to be checked.
2. align the beamsetter box with
the middle of the headlamps.
It must not be more than 3
cm out of line horizontally or
vertically.
3. If the beamsetter has a
positioning aid, please turn
to Section 6.3. The distance
between the front edge of
the beamsetter box and the
headlamp should be between
30 and 70 cm (Fig. 3).).
Aligning the housing of the
beamsetter box to the vehicle
(using the broad-band sight)
•
Beamsetters with a wheeled
base must be aligned to each
headlamp separately.
•
Beamsetters on rails only
need to be aligned once for
each vehicle.
1. Loosen the column clamp..
2. Use the broad-band sight to align the beamsetter box in such a way that the sight line (slit) touches two points
lying at the same height and symmetrically to the vehicle’s longitudinal axis (Fig. 3).
3. Tighten the column clamp without altering the alignment.
4. When the clamping screw has been loosened, the broad-band sight can be moved to the left or the right in
order to make sighting easier.
Vertical adjustment of the broad-band sight.
1. The points aimed for on the vehicle must be clearly below the sighting height.
2. After loosening the hand-wheel (by turning it anti-clockwise) the sight holder on the column can be adjusted
for height. If alignment proves difficult, for instance with certain makes of trucks or buses with a deeply curved
front end, the centre line of the headlamps can be extrapolated to the floor by means of a plumb-line or similar
and then picked up from there with the sight (fig. 4).
