HYDRAULIC SAFETY
• Always inspect hydraulic components and hoses
before using. Replace any damaged or worn parts
immediately.
• If you suspect a hose leak, DO NOT use your
hand to locate it. Use a piece of cardboard or
wood.
FUSES
The SnowEx®electrical and hydraulic systems contain
several blade-style automotive 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 re. 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-tting 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 re extinguisher rated BC handy,
for ammable liquids and electrical res.
WARNING
