OPERATIONAL TESTS AND FINAL ADJUSTMENTS
FINAL INSPECTION AND ADJUSTMENT
WARNING
Keep 8' clear of the blade when it is being
raised, lowered or angled. Do not stand
between the vehicle and the blade or directly
in front of the blade. If the blade hits or drops
on you, you could be seriously injured.
1. Attach the snowplow to the vehicle mount. With
the snowplow lowered to the ground and on
level pavement, measure the dimension from the
ground to the center of the pivot bar cap screw.
This dimension must be 9-3/4"–11-1/4".
2. With the snowplow attached and on the ground,
place the stand arm in the lower position with
the lock pin engaged and with the stand shoe
fully retracted in the "UP" position. Measure
the distance from the ground to the bottom
of the stand shoe. This distance should be
1-3/8" to 2-1/8". The stand can be adjusted to
achieve this dimension by removing the roll pin
and selecting the proper hole in the stand stem.
When the stand height is correct, cut and remove
the spring tie.
3. Final lift chain link adjustment must be made after
the snowplow is assembled with the proper pivot
plate position. On a level surface with the blade
on the ground and the lift ram fully collapsed,

attach the chains to the lift arm hooks in the
tightest possible link. This adjustment will provide
for optimum transport height, blade float, and
stacking stop clearance. When the chain tension
is correct, the A-frame will not contact the lift
frame when the blade is fully raised.
4. Check that the trip springs are adjusted correctly
by confirming that the coils of the springs are
separated slightly.
Overtightening springs will not increase blade
trip force and can damage the springs.
5. Adjust the trip springs by loosening the bottom
nuts and then tightening the top nuts until the
coils of the springs begin to separate (a piece of
paper such as this instruction sheet should pass
between the second and third coils). Tighten the
bottom nut against the trip spring brackets to lock
in place.
6. Fully raise the blade and verify that it does not
block the headlamp beams. If the blade blocks the
headlamp beams, lower the blade to the ground,
collapse the lift ram and lengthen each chain by
one link. Repeat this process, lengthening the
chains by one link each time, until the blade does
not block the headlamp beams.
