BLADE DROP SPEED ADJUSTMENT
The quill in the valve manifold adjusts the blade
drop speed.
1. Lower the blade to the ground before making
the adjustment.
2. Remove the hydraulic unit cover.
WARNING
Keep 8' (2.4 m) 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.

HYDRAULIC SYSTEM
Hydraulic Fluid
For hydraulic fluid type and filling instructions, see
"Annual Fluid Change" under "Hydraulic System"
in the Maintenance section of this manual.
Relief Valves
The hydraulic unit's valve manifold includes relief
valves to prevent damage to the blade or vehicle if
an obstacle is hit at either end of the blade. When
force against the blade causes the pressure
in
an extended ram
to exceed set limits, the relief
valve opens allowing fluid to escape and the ram
retracts.
The valves are preset at the factory and do not
need any adjustments unless the valve manifold
is serviced.
