BLADE DROP SPEED ADJUSTMENT
The quill in the valve manifold adjusts the blade drop
speed.
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 hydraulic unit 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.

FINAL INSPECTION AND ADJUSTMENT
1.
Fully angle the blade in both directions in raised
and lowered positions. Adjust hose fittings, wraps,
and clamps so hoses do not contact vehicle
bumper, have no sharp bends, and are wrapped
at contact points with, and do not become pinched
between the headgear and T-frame.
2.
Apply grease to the two hitch pin grease fittings
and the stand actuator pin grease fitting.
WARNING
Keep 8' clear of the blade when it is being
