Setting up aiming device

The distance between the aiming device and the headlamp should
be just enough so that setting operations can also be carried out
on the headlamp from in front (about 30 cm).
The center of the lens on the aiming device should differ by less
than 3 cm from the headlamp center. The center of the lens is
identified by marks (see Fig. 2, No. 5).
In order to adjust the height of the aiming device, the hand roller ist
turned (1) and a brake is released. The brake automatically looks
in place again when the roller is released.

2.5 Aligning the aiming device with the longitudinal axis
of the vehicle
2.5.1 Vehicles with flat engine-compartment lid
By swinging the mirror arm (Fig. 1, Pos. 2) the alignment mirror
(Fig. 2, Pos. 1) is set above the head towards the operator so that
the front of the vehicle with two outer symmetrical reference
points (for example, the upper edge of the headlamps, joints in the
engine hood, etc.) are visible in it.
The aiming device is aligned on the longitudinal axis of the vehicle
so that the positioning line on the mirror touches these two outer
reference points equally (see Fig. 5).
With the mobile aiming devices (EFLE 50, 51, 60 and 61), this is
done by moving the aiming device using the wheeling handle.
The floor-rail aiming device (EFLE 52 and 62) is turned as required
with the rotary knob at the top of the support column (Fig. 3, No. 1).

2.5.2 Cab-over-engine vehicles
In vehicles with vertical front section the centres of the headlights
are marked with chalk on the floor using a plumb bob. The centres
can be connected with a rail. These markings are lined up in the
adjusting mirror.

Adjusting the aiming device

The setting used for aiming headlamps is the inclination value in cm
which the cut-off must have at a distance of 10 m.
This setting is given in Section 3.1, and is made before the test at
the rotary knob (Fig. 4, No. 2).
The vehicle should be loaded as specified.
