CHECKING THE AIMER
Once the beam is aligned, place the aimer in front of one of the lights, as described in the
instructions, and check if the projection of the beam on the internal screen is the same.
Following tolerances are allowed:
TOLERANCES
The Standard SAE J600 allows a tolerance of ±0.3º (±1.6 in, or ±40mm) for the vertical
aim, and ±0.6º (±3.2 in, or ±80mm) for the horizontal.
The tolerance limits are shown in the figure below.
