Haynes says:

"To make a temporary adjustment, position the vehicle on level ground about
3 meters (10ft) in front of a vertical wall or a piece of board secured
vertically. The wall or board should be square to the center-line of the
vehicle and the vehicle should be normally laden. Check that the tire
pressures are correct.
Draw a vertical line on the board or card in line with the vehicle
centerline.
Bounce the vehicle on its suspension several times to ensure correct
leveling and then accurately measure the height between the ground and the
center of the headlamps.
Draw a horizontal line across the wall board at the same height as the
headlamp centers and on this line mark a cross on either side of the center
line at the same distance apart as the headlamp centers.
Now locate the adjusters. On models with square headlamps there are four
adjuster per side (see illustration....if you think I'm going to try that,
well...........)
Switch the headlamps on to full beam and using the adjusters, adjust each
headlamp to align the beam to shine just below the corresponding cross on
the wall or board.
Bounce the vehicle on its suspension again to check that the beams return to
the correct position. At the same time check the operation of the dipswitch
to confirm that the beams dip correctly. Switch off the headlamps on
completion."
