OPERATING YOUR SNOWPLOW
6.
Retighten the breather/fill plug.
7. Reconnect the snowplow battery cable to the
vehicle battery cable.
8. Turn the vehicle ignition to the "ON" or
"ACCESSORY" position. Turn the control ON.
9. While pressing the RAISE button on the
snowplow control, note the hydraulic gauge
pressure reading as the blade is rising. (The
pressure can
only
be read
as the blade is
rising
. It may be necessary to perform this
process more than once to obtain an accurate
reading.) The recommended pressure is
350 psi.
CAUTION
Never operate the unit while adjusting the
scrape lock valve. Doing so will damage
the scrape lock valve O-rings.
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 amperage draw and will shorten the
life of the plow motor.
