DO NOT stand between the Plow and
the vehicle when it is being angled.
FAILURE TO HEED CAN RESULT IN
SERIOUS PERSONAL INJURY.
NOTE:
There are four possible failures that could
cause the angling solenoids not to operate. They
are: joystick or associated wiring, solenoid coil,
plunger or spool valve.
Hold the metal end of a screwdriver about 1/8”
from the coil nut on the solenoid coil being test-
ed.
Actuate the angle switch. The metal end of the
screwdriver should be pulled to the coil nut when
the switch is actuated.
If not, use a voltmeter to test for battery voltage
at the coil terminal when the switch is actuated.
See page 23.
If battery voltage is present, replace the coil.
If no voltage is indicated, check wiring, joystick
and grounds, repair or replace as necessary.
