Lit. No. 72451, Rev. 03 17 October 15, 2019
OPERATING YOUR SNOWPLOW
SECURITY GUARD™ SYSTEM
Activation & Establishing a 4‑Digit
Security Code
NOTE: Snowplow must be attached to vehicle,
and all electrical connections must be connected
prior to activating the security code function.
The SECURITY GUARD feature was developed as
an electrical anti-theft system. The system provides
a deterrent against theft and/or non-permitted use
by allowing you to electronically lock the snowplow's
hydraulic functions.
All multiplex snowplow controls come equipped with
the SECURITY GUARD system. To use this function,
you must complete the activation process.
1. Turn the vehicle ignition switch to the "ON" or
"ACCESSORY" position. (It is not necessary to
start the vehicle.)
2. Verify that the control power indicator is OFF. If
the power indicator light is red, the control is ON.
Move the ON/OFF switch to "OFF" or push the
ON/OFF button to turn the control OFF.
3. To activate the SECURITY GUARD mode, move
the control lever to the #1 position or press the #1
button four consecutive times, and then move the
lever to the #4 position or press the #4 button four
consecutive times (sequence: 1, 1, 1, 1, 4, 4, 4, 4).
The green FLOAT light will ash quickly and the
red power indicator light will turn ON, indicating
that the system is ready to accept your 4-digit
security code.
4. Enter your 4-digit security code by moving the
control lever to (or pressing the button for) any four
of the eight positions: UP, DOWN, LEFT, RIGHT,
1, 2, 3, or 4.
5. After you have entered your 4-digit security code,
the FLOAT light will stop ashing and the power
indicator light will turn OFF. This indicates that
your 4-digit security code is entered and stored in
the SECURITY GUARD system.
NOTE: If the control is turned ON prior to
completing the programming procedure, your
4‑digit security code will be cancelled.
Once a 4-digit security code is established, the
SECURITY GUARD system will recognize any control
that has been programmed with the same 4-digit
security code. If a control not programmed with the
correct 4-digit code is connected to the system, the
established security code will have to be entered
manually before the snowplow can be activated (see
the Manual Unlock Procedure below).
Manual Unlock Procedure
If the SECURITY GUARD system is activated and you
are using a control with a dierent 4-digit code than
the established security code, you will be required
to manually enter the 4-digit security code before
operating a locked snowplow.
1. Turn the vehicle ignition to the "ON" or
"ACCESSORY" position.
2. Move the ON/OFF switch to the "ON" position
or push the ON/OFF button to switch the control
ON. The power indicator light will ash rapidly,
indicating that the snowplow is locked.
3. Enter the 4-digit security code.
4. After the correct security code is entered, the
power indicator light will change from ashing
rapidly to a solid light to indicate that the snowplow
has been successfully unlocked.
NOTE: If the plow/vehicle electrical connection
is lost or disconnected, the SECURITY GUARD
system will reset, requiring any control that is not
programmed with the established 4‑digit security
code to manually re‑enter the security code to
activate the snowplow.
