Blade Drop Speed Adjustment
1. Lower the blade to the ground before making
any adjustment.
2. Remove the hydraulic unit cover according to
the instructions for your blade:

For hydraulic
fl
uid type and
fi
lling instructions, see
"Annual Fluid Change" under "Hydraulic System"
in the Maintenance section of this manual.
Relief Valves
The FloStat
®
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
fl
uid 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.
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.
