5.2. HBS Column Brake

The HBS is fitted with a rotating column, which aids correct alignment. To release or apply the column brake put pressure on foot pedal (fig. 4).

6.1. Start engine, so that battery is not drained.

6.2. Align the HBS with the centre of the headlamp to be tested, as in Section 5.

6.3. With an assistant sitting in the driving seat, switch on the headlamp to the beam, dip or main, which is to be checked.

Note: When checking headlamp aim on vehicles with hydropneumatic suspension systems, it is necessary to have the engine idling.

6.4. Determine the appropriate dip beam image and the aim (see figs. 6 & 7). Headlamps of older vehicles (approx. pre 1950) may have

beam images which do not conform. In such cases check:

a) DIP BEAM headlamps are aimed so they do not dazzle, ie the brightest part of the beam image is aimed at least 0.5% below the

horizontal, or, for headlamps which cannot be checked on dip beam, check:

b) MAIN BEAM headlamps are aimed so that the beam image centre is on or slightly below the horizontal (fig. 8).

6.5. Graduated Screen

5.1. Positioning

Locate the HBS approximately 200 to 500mm from the vehicle headlamp.

5.1.1. Standing behind the HBS, use the visor to align with a horizontal, or two symmetrical points on the vehicle i.e. the bonnet lip or the

bottom of the windscreen.

5.1.2. Ensure the visor line is parallel with the horizontal, or symmetrical selection, by rotating the column, to ensure that the HBS is square with

the front of the vehicle.

5.1.3. Measure the height of the centre of the headlamp from the floor - say 650mm as an example.

5.1.4. Squeeze the locking lever (fig. 3. C) on the vertical sliding system and move the system up or down the column until the top edge of the

slider (fig. 3.D) aligns with 65cm (650mm) on the column scale. Release locking lever. Centre of lens will now be at the same height

(650mm) as the centre of the headlamp.

5.1.5. Use the sighting line on the top of the optical system housing to horizontally align the HBS with the centre of the headlamp.

IMPORTANT

The HBS system uses a fixed graduated

screen in accordance with the requirements

of the MOT regulations.

6.6. Dipped Beam

6.6.1. Prepare the HBS and the car as previously instructed, then turn on the dipped beam.

6.6.2. Check that the headlamp beam tolerances are in accordance with the MOT inspection manual and are within the operating tolerances

specified by the manufacturer.

6.6.3. Adjust the headlight(s) until you obtain the required result.

6.6.4. When testing the more commonly used asymmetrical headlight (see fig. 6), remember that the projection will light up a section on

the LEFT hand side of the plate at an angle of about 150above the horizontal plane. Just under the centre, on the left, a small zone will

appear brighter than the rest of the projection.

HBS97A & HBS971A - 2 - 281003

When testing symmetrical dipped beams

the projection on the plate should be a

horizontal line.

Correct projection on panel.

SYMMETRICAL DIPPED BEAM

It is necessary to obtain a strong bright zone at the

centre of the plate, where the black spot is located.

ASYMMETRICAL DIPPED BEAM

In addition to the numerically calibrated scales the luxmeter has a colour coded scale for main beam intensity which should be read as follows:

Main Beam

1. Indicator at RED/GREEN (BAD/GOOD) limit: Acceptable for vehicles travelling under 30mph (48km/h) and motorcycles.

2. Indicator at the centre of GREEN (GOOD): Acceptable for vehicles travelling over 30mph (48km/h).

3. Indicator on BLUE (HALOGEN): Acceptable for vehicles with halogen headlights.

7. THE LUXMETER

HBS97A & HBS971A - 2 - 281003

We suggest that the unit has periodic calibration checks in situ. If the unit is covered by a service agreement with the MOT package installer,

they will carry this out on your behalf. You may however, wish to calibrate the unit yourself.

8. CALIBRATION

The headlamp beam setter can be recalibrated using a laser alignment calibration unit. We recommend the Sealey AK9999 (available from

your authorised Sealey dealer).

We recommend that the laser calibration device be set up and levelled first of all, the beam setter can then be manouvered easily on its stand

with reference to the position of the laser. The laser can be placed on any surface such as a car bonnet, box, table etc of suitable height.

8.1 Using the calibrated spirit level within the laser alignment calibration device, ensure that the unit is flat and level.

8.2 Switch the laser on. Manouver the beam setter in order to centre the laser beam in the beam setter lens. This must be done by eye.

There is a ±20mm tolerance on centralisation of the beam through the lens. The beam setter should be approximately 2m from the

laser.

8.3 The dot projected onto the aiming screen should bisect the 0º line, at the far left, centre and far right of the screen. It is necessary at

this point to rotate the column through the vertical axis, to track the beam from one side of the aiming screen to the other. Take care to

ensure that the laser remains level throughout.

Alignment OK

Adjust screen

8.4 To adjust the aiming screen, use the two holding screws.

8.4.1 Loosen the screws and reposition the screen, so that the projected laser dot correctly bisects the 0º line.

8.4.2 Retighten the screws, taking care not to move the screen back out of position.

Aiming screen

Holding screws

The Headlamp Beam Setter is equipped with a spirit level located on the base of the optical box, which is visible through the transparent panel.

To level the box, loosen screws (fig.3.A & B) located on the side of the box and adjust the box until the spirit level registers horizontal. Re-tighten

the screws. The box level must be checked every time it is used on a different working surface.

10.1. The paint work is detergent resistant. Clean with a damp cloth, removing any stains. A small amount of alcohol may be applied to

stubborn areas of grime.

10.2. DO NOT leave the machine in areas where corrosive vapour is present, i.e. from battery charging or paint spraying etc.

10.3. DO NOT oil the column.

10.4. An optical box dust cover is available upon request.
