Western DEFENDER - Hydraulic Unit; System Capacity; Cab Controls

Lit. No. 72451, Rev. 03 12 October 15, 2019
HYDRAULIC UNIT
The hydraulic system gives you full control of the
snowplow from the driver's seat. Two single-acting
hydraulic rams hold the blade at the desired angle.
The hydraulic unit's manifold has built-in blade scrape
lock circuitry. This feature resists the tendency of a
snowplow to "oat up" when large amounts of snow
build up in front of the blade while plowing deep snow
or stacking snow into piles.
The scrape lock feature is factory set. See your sales
outlet for adjustment.

GETTING TO KNOW YOUR SNOWPLOW
CAB CONTROLS
The controls are electrically powered through the
ignition (key) switch of your vehicle and are protected
by a replaceable in-line fuse. The ON/OFF switch
allows you to turn OFF the control and prevent blade
movement even when the ignition is ON.
The ON/OFF switch serves as an emergency stop
when required.
