Horizontal & Vertical Adjustments

Horizontal Adjustment:

HORIZONTAL ADJUSTMENT
1. Set horizontal dial to zero.

2. Check to see that the split image target lines are visible in the viewing port. If necessary, rotate each aimer slightly to locate the target.

Vertical Adjustment:

VERTICAL ADJUSTMENT
1. The vertical dial should be set at zero. (For passenger vehicles an "0" setting is generally required. For special settings, consult local state laws.)

2. Turn vertical adjusting screw until the level bubble is centered between the lines.

3. Repeat the last two steps on the opposite headlight.

4. Re-check target alignment on both aimers and readjust horizontal aim if necessary.

5. Remove aimers by pressing "vacuum release" button located on piston handle.
