Instructions for putting into operation
Before the headlight aiming device is put into initial operation the alignment mirror and the handle on EFLE 50, 51, 60 and 61 must be turned to the working position.
Operations required to do this
Release the locking screw (1) on the equipment support column using a 4mm hexagon-socket screw key.
- Swing the arm holding the alignment mirror 180^ upward (2).
Tighten the locking screw again.

Operations required to do this
Release the locking screw (1) on the equipment support column using a 5mm hexagon-socket screw key.
- Swing the handle 90^ outwards.
- Insert the locking screw in the hole and tighten.

1. General
Headlamps on motor vehicles must not blind the drivers of vehicles coming from the opposite direction. The inclination and the aiming of the headlamp light beam to the side must therefore be adjusted according to legal specifications.
In order to make these legally specified adjustments of motor-vehicle headlamps, Bosch supplies the following aiming devices:
1.1 Mobile headlight aiming devices EFLE 50,EFLE 51,EFLE 60 and 61
The surface on which the headlight aiming device is set up must be even but it does not have to be horizontal. In order to achieve the specified measurement accuracy, surface irregularities within the area where the aiming device is used must be less than 1.2mm

1.2 Headlight aiming device on floor rails EFLE 52 and EFLE 62
The standing surface for the vehicle and the guide rails of the apparatus must be horizontal and parallel to one aonther. In order to achieve the prescribed measuring exactness, the horizontal deviation of the guide rails must not be more than 1.3mm out of line with respect to one another.

2. Prerequisites for aiming the headlamps
2.1 Operating site
The operating site must meet the conditions specified in Sections 1.1 and 1.2 above.
2.2 Tire-inflation pressure
All tires must be inflated to the pressure specified for the particular vehicle.
2.3 Headlamps
Deflective lenses and reflectors, as well as blackened bulbs must be replaced before the aiming adjustment.
With headlamps that are fitted with an adjusting device, observe the following:
In order to aim headlamps on vehicles fitted with a device for infinitely variable adjustment of the headlamps by hand, the adjusting device must be in the specified detent position.
When the headlamps are fitted with an adjusting device that can be set to only 2 detent positions, proceed as follows:
- With vehicles in which the headlamp beams are directed upward as the load increases (loading space at the black), the headlamps should be aimed with the adjusting device in the "high" lightbeam detent position.
- With vehicles in which the headlamp beams are directed downward as the load increases (loading space at the front), the headlamps should be aimed with the adjusting device in the "low" light-beam detent position.
2.4 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 3cm 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).
Fig. 5
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.
Fig. 6
2.6 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 10m
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.
3. Aiming regulations
Please observe the aiming regulations valid in your country.
4. Measuring images
The measuring images can also be observed from the rear of the aiming device by means of the deflection mirror (Fig. 10, No. 3).
Before every measurement the prerequisites given in Section 2 above must be complied with.
4.1 Headlamps with asymmetrical lower beam
With headlamps used for an asymmetrical lower beam, the lower beam cut-off line must coincide with the boundary line to the left of the center point. The point of intersection between the left-hand part of the lower beam cut-off line (as horizontal as possible) and the right-hand rising part of this line must be located on the vertical line that passes through the center mark. In order to determine this point of intersection more easily, the left-hand half of the handlamp can be alternately masked and unmasked serveral times.
After the lower beam cut-off line has been set according to specifications, the center of the high beam with headlamps on which the lower beam and upper beam can be aimed together must lie within the limit corners inscribed around the center mark.
With high-beam headlamps fitted with their own adjustment mechanisms, the center of the light beam must be positioned on the center mark.
4.2 Headlamps with symmetrical lower beam, and fog lamps
With headlamps used for a symmetrical lower beam and with fog lamps, the highest part of the lower beam cut-off line must touch the boundary line, must be as horizontal as possible across the width of the test surface.
To the side, these headlamps must be aimed so that the distribution of the light is as symmetrical as possible with respect to the vertical line that passes through the center mark.
After the lower beam cut-off line has been set according to specifications, the center of the high beam with headlamps on which the lower beam and upper beam can be aimed together must lie within the limit corners inscribed around the center mark (see Fig. 8).
With high-beam headlamps fitted with their own adjustment mechanisms, the center of the light beam must be positioned on the center mark (see Fig. 8).
Example: Boundary line for the lower eam cut-off with an asymmetrical lower beam.

Example: Center mark and boundary corners for the center of the higt beam.

4.3 Headlamps with inclination data
In the case of single-axle towing vehicles or machines with headlamps permanently set to the lower beam and on which the inclination of the light beam center is given, the center of the beam must lie on the boundary line and on the vertical line that passes through the center mark.
5. Luxmeter
Using the luxmeter, the illumination from the headlamps can be tested (measured) after they have been aimed.
During these tests the rotary knob for the setting must always be set to the position 10cm / 10m
Lower beam: The illumination must be below the permissible glare value. Press the pushbutton on the luxmeter. The pointer must remain within the green range on the scale marked "A".
High beam: The illumination must reach the minimum permissible value. The pointer must come up to the green range on the德拉 marked "F".

6. Maintenance and care
The headlight aiming device is a high-precision optical measuring instrument. In order to preserve its measurement accuracy, shocks and rough handling must be avoided.
At regular intervals its accuracy is to be checked.
This is especially important for workshops which carry out their work according to legal regulations.
For this purpose we recommend that a maintenance contract be concluded with the responsible Bosch Customer Service. This will ensure that the aiming device will be checked and tested by trained personnel using the right test equipment and according to plant specifications.
For maintenance purposes the wheels should be lubricated occasionally with a few drops of oil.
The support column must be kept dry and free of grease and oil!
Wipe the lens and the reflector with a soft cloth to keep them clean.
