SECURITY GUARD System Enabled Controls Have
Numbers 1 Through 4 on the Faceplate.
CONTROL OVERVIEW
The SECURITY GUARD feature was developed as an
electrical anti-theft system for snowplows. The system
provides a deterrent from theft and/or non-permitted
use by allowing you to electronically lock the
snowplow's hydraulic functions.
To use this function, you must complete the
"Activation" process.
Each control is equipped with an ON/OFF switch and
an indicator light to show when the control is powered
ON or OFF. The controls are powered by the vehicle's
battery, so your vehicle ignition (key) switch must be
ON to use the controls.
Before Activating the SECURITY GUARD
System:
Install the control as stated in the Joystick Control Kit
Installation Instructions, and check all plow functions
as described below.
OPERATING INSTRUCTIONS
1. Turn the vehicle ignition switch to the ON or the
ACCESSORY position.
2. Move the slide switch on the side of the control to
the "ON" position. The control indicator light glows
red, indicating the control is ON. The indicator light
glows red whenever the control and the vehicle
ignition switch are both ON and the electrical
connections to the plow are completed.
The ON/OFF switch operates as an emergency stop if
required.
WARNING
To prevent accidental movement of the
blade, always turn the ON/OFF switch to OFF
whenever the snowplow is not in use. The
control indicator light will turn off.
