mounted and raised in the transport position. See
Aiming Headlamp Beams in the Maintenance
section for instructions.
• Aim the vehicle headlamps with the snowplow
removed from the vehicle.
BLADE DROP SPEED ADJUSTMENT
The quill in the front of the valve manifold adjusts the
blade drop speed.
NOTE: The blade will not drop when quill is fully
tightened (clockwise). Turn OFF the plow control,
turn the quill 1/8 turn outward (counterclockwise),
then proceed with blade drop speed adjustment.
1. Lower the blade to the ground before making
adjustment.
2. Turn the quill IN (clockwise) to decrease drop
speed. Turn the quill OUT (counterclockwise) to
increase drop speed.
3. Stand 8' clear of the blade drop zone when
checking adjustment.
WARNING
Keep 8' clear of the blade drop zone when it is
being raised, lowered or angled. Do not stand
between the vehicle and blade or directly in
front of blade. If the blade hits you or drops
on you, you could be seriously injured.
