OPERATING YOUR SNOWPLOW
10. If the hydraulic pressure reading is less than
350 psi, increase the pressure by turning the
scrape lock valve stem clockwise 1/4 turn and
retest pressure.
NOTE: Adjustments should be made in
1/4-turn increments.
11. Repeat Steps 9 and 10 until the recommended
pressure (350 psi) is obtained.
NOTE: Adjusting the scrape lock pressure
in excess of the recommended pressure will
increase amp draw and will shorten the life of
the plow motor.

lower the blade completely and turn the
control OFF. Turn the vehicle ignition to the
"OFF" position.
