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

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 CHECK VALVES for contamination
Poppet must move freely, and seat and piston area
must be clear of any debris
Remove CHECK valves and clean
Replace CHECK valve
Check RELIEF valves for contamination
Poppet must move freely, and seat must be clear of
any debris
Remove RELIEF valves and clean
Replace RELIEF valves
