Introduction
Whenever service is necessary, your local dealer knows
your plow best and is interested in your complete
satisfaction. Return your snowplow to your local dealer for
maintenance service or any other assistance you may
require. If you are unable to do so, this troubleshooting
guide should help you determine the problem. However,
before attempting the servicing of your plow, you should
possess good mechanical abilities and a total
understanding of the mechanism.
PLEASE: Before calling parts and service personnel be
certain that:
1. You have read this guide carefully and are certain
that all of the suggestions pertaining to your problem
have been attempted.
2. You have the following available:
A. Date snowplow was originally installed
B. Power Pack Serial Number
C. Controller Serial Number
D. Blade Serial Number
E. Pump Serial Number
This information should be recorded on page 2 of this
Owners Manual.
Troubleshooting Guide - Quick Reference
1. Before continuing through guide check connections
on all power and ground wires and make sure the control
is functioning properly.
2. After removing any valve from the valve block make
sure the port is free from all metal shavings before
reinstalling.
3. Any adjustments done to reliefs on the power unit
over factory pressure settings WILL VOID warranty.
4. A 9V battery can be used to check if the coils are
functioning properly. Place the two tabs on the coil onto
the positive and negative sides of the 9V battery. If the
coil is good this will magnetize the coil.
5. Functions are ground switched. Power should be
present at all coils when plow power is plugged in and the
control is turned on. To check a function you are looking
for a solid ground coming from the control receiver.
6. To check if a ground is present, use a test light
connecting the wire lead from the test light to the ground
wire in question on the plow. touch the test light to the
motor solenoids top post that the main battery harness is
connected to. If the test light has a ground path during
the plow operation it will light up. If it does not light up
there is no ground path.
