SYMPTOM/DIAGNOSTIC

 RESULT

 FIX

PLOW WON'T ANGLE IN ONE DIRECTION

Check voltage at SC VALVE coil

If no voltage present, check cable and 
connections

Replace/repair cable or connections

Confirm ORANGE wire at SC VALVE

Check SC VALVE for contamination

Spool must move freely, and seat area must be 
clear of any debris

Remove SC VALVE and check free movement of 
spool, clean any chips/debris from valve

Replace SC VALVE

PLOW DRIFTS WHILE PLOWING SNOW

Air in Fluid

Bleed air from system

Slightly loosen fittings to angle cylinders and angle 
the plow.  Tighten fittings while fluid is escaping.  
Do this over an absorbent mat, or hold a rag over 
fitting to absorb excess fluid.

Check ANGLE LOCK valve for contamination

Poppet must move freely, and seat and piston area 
must be clear of any debris

Remove ANGLE LOCK valve and clean

Replace ANGLE LOCK valve

Check CROSS RELIEF valve for contamination

OIL IS LEAKING FROM CYLINDERS

Packing is loose

Tighten until leak stops

Rods are pitted

Polish rods with fine steel wool

OIL SPRAYS OUT OF VENT PORT IN POWER UNIT

Air in Fluid

Bleed air from system

Slightly loosen fittings to angle cylinders and angle 
the plow.  Tighten fittings while fluid is escaping.  
Do this over an absorbent mat, or hold a rag over 
fitting to absorb excess fluid.

Check fluid level

Fluid should be visible in elbow fitting at end of 
reservoir.

Remove fluid if necessary - in most cases the 
problem will subside as entrapped air dissipates.

PLOWING TIPS

• Know the area you are plowing. Be aware of all hidden obstacles (pipes, drains, berms, etc.)
• Plow with the storm, do not let snow accumulate
• Always lower the plow blade when parking to minimize the risk of the plow dropping and to reduce the load on 
the truck suspension.
• When transporting the plow – monitor coolant temperature. If the truck is running hot, adjust the plow position 
to allow additional airflow to the radiator.
• Plowing at high speeds increases the potential for damage to your plow AND your truck
