Section 9. Plow Light Beam Aiming Procedure
A.)
Vehicle must be on level surface 25 feet in front of matte-white screen, such as a garage door.
The screen should be perpendicular to both the ground and vehicle centerline.
B.)
Vehicle should be ballasted for snow plowing with a driver. Snowplow Blade should be in place
and in the raised position.
C.)
This list shows points listed by the Society of Automotive Engineers (SAE) pertinent to headlamp
aiming in specification #SAE J599.
1.)
Remove ice or mud from under fenders.
2.)
See that no tire is noticeably deflated.
3.)
Check Springs for sag or broken leaves.
4.)
Check functioning of any 'Level-Ride' control.
5.)
Check Plow Light Lens and aiming system for loose or broken parts.
6.)
Check Bulbs for burnouts and proper beam switching.
7.)
Stabilize suspension by rocking vehicle sideways.
D.)
Mark or tape the vertical centerline of the Plow Lights and the centerline of the vehicle on the screen.
Mark or tape the horizontal centerline (distance up from the floor) of the Plow Lights on the screen.
E.)
The correct visual aim for Type 2 Plow Lights (see number on face of sealed beam) is with the top
edge of the high intensity zone of the lower beam below the horizontal centerline and the left edge of
the high intensity zone on the vertical centerline (see diagram below).
