INSTALLATION INSTRUCTIONS
BLADE DROP SPEED ADJUSTMENT
The quill in 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 any
adjustment.
2. Remove the hydraulic unit cover.
3. Turn the quill IN (clockwise) to decrease drop
speed. Turn the quill OUT (counterclockwise) to
increase drop speed.
4. Stand 8 feet clear of the blade when checking
adjustment.
5. Replace the cover.
WARNING
Keep 8' clear of the blade when it is being
raised, lowered, or angled. Do not stand
between vehicle and blade or directly in front
of the blade. If the blade hits or drops on you,
you could be seriously injured.
Use good quality
FINAL INSPECTION AND ADJUSTMENT
1. Fully angle the blade in both directions in raised
and lowered positions. Adjust hose ttings, wraps,
and clamps so that the hoses do not contact
the vehicle bumper, have no sharp bends, are
wrapped at contact points, and do not become
pinched between the headgear and A‑frame.
2. Add grease to the two hitch pins.
WARNING
Keep 8' clear of the blade when it is being
raised, lowered, or angled. Do not stand
between vehicle and blade or directly in front
of the blade. If the blade hits or drops on you,
you could be seriously injured.
