SAFETY DEFINITIONS

NOTE: Indicates a situation or action that can lead
to damage to your snowplow and vehicle or other
property. Other useful information can also be
described.

BEFORE YOU BEGIN

• Park the vehicle on a level surface, place shift

lever in PARK or NEUTRAL and set parking brake.

 WARNING

Indicates a potentially hazardous situation,
that if not avoided, could result in death or
serious personal injury.

 CAUTION

Indicates a potentially hazardous situation
that, if not avoided, may result in minor or
moderate injury. It may also be used to alert
against unsafe practices.

SAFETY

 WARNING

Lower blade when vehicle is parked. Temperature
changes could change hydraulic pressure,
causing the blade to drop unexpectedly or
damaging hydraulic components. Failure to do
this can result in serious personal injury.

 WARNING

The tester shall keep bystanders clear of the
blade during this test. Do not stand between the
vehicle and the blade or within 8 feet of a
moving blade. A moving or falling blade could
cause personal injury.

 CAUTION

Before starting any on-truck test, the snowplow
must be properly attached to the vehicle.

FUSES

The snowplow electrical and hydraulic systems
contain several automotive blade-style fuses. If a
problem should occur and fuse replacement is
necessary, the replacement fuse must be of the same
type and amperage rating as the original. Installing a
fuse with a higher rating can damage the system and
could start a fire. Fuse Replacement, including fuse
ratings and locations, is located in the Maintenance
Section of the Owner's Manual.

PERSONAL SAFETY

• Remove ignition key and put the vehicle in park or

in gear to prevent others from starting the vehicle
during installation or service.

• Wear only snug-fitting clothing while working on

your vehicle or snowplow.

• Do not wear jewelry or a necktie, and secure long

hair.

• Wear safety goggles to protect your eyes from

battery acid, gasoline, dirt and dust.

• Avoid touching hot surfaces such as the engine,

radiator, hoses and exhaust pipes.

• Always have a fire extinguisher rated BC handy,

for flammable liquids and electrical fires.
