PROBLEM
CAUSE
SOLUTION
Reference
Low hydraulic fluid level.
Check and refill hydraulic system to
proper level.
Cold hydraulic fluid.
Allow hydraulic fluid to warm up to
operating temperature.
Engine R.P.M. too slow.
Increase engine R.P.M.
Hydraulic pump failing.
Refer to Power Unit’s manual for
service recommendations.
Hydraulic hose restriction.
Check for evidence of restriction /
damage in hydraulic hoses.
Hydraulic hose restriction.
Check for evidence of restriction /
damage in hydraulic hoses between
actuators and control valve.
Flow control / needle valve
setting out of adjustment
.
Turn flow control / needle valve
clockwise to slow and counter
clockwise to speed up.
Soft surface.
change to rubber cutting egde for soft
or decotative surfaces.
Blade tipped forward too far.
Tip blade back to ride on skid shoes.
Excessive down pressure on loader
hydraulics.
Limit use of “float” position if possible.
Decrease down pressure in manual
mode.
Blade tipped ahead too far.
Tip blade back to ride on skid shoes.
Cutting edge trips too easily.
Tension too loose on trip springs.
Increase tension on trip springs.
Thin film of oil/fluid on body of
actuator.
Normal occurrence.
No action required.
Green lubricating grease between
wing actuator body and endcaps.
Normal occurrence in first 10 hours
of use
(factory packing grease)
.
No action required.
Wings hitting front tires on power
unit.
Tire protector not set properly for
power unit width.
Set tire protector system to push wing
out more.
check fuses / power / harness to
diverter valve.
check electro magnetic coils.
Wing Hydraulics not working.
diverter valve not working.
Wing rotation speed too fast or too
slow.
Excessive wear on cutting edge.
Hydraulics react slowly.
Cutting edge digging into surface.
Angle cylinder too fast or too
slow
Power unit flow is adjusted slow
Increase flow from power unit
