FIRE AND EXPLOSION

Be careful when using gasoline. Do not use gasoline 
to clean parts. Store only in approved containers away 
from sources of heat or 

fl

 ame.

A driver's

 rst responsibility is the safe operation of 

the vehicle. The most important thing you can do 
to prevent a crash is to avoid distractions and pay 
attention to the surroundings. Wait until it is safe to 
operate mobile communication equipment such as
cell phones, text messaging devices, pagers, or 
two-way radios.

VENTILATION

BATTERY SAFETY

NOISE

Airborne noise emission during use is below 95 dB(A) 
for the snowplow operator.

VIBRATION

Operating snowplow vibration does not exceed 2.5 m/s

2

 

to the hand-arm or 0.5 m/s

2

 to the whole body.

TORQUE CHART

SAFETY

 CAUTION

Batteries normally produce explosive gases 
which can cause personal injury. Therefore, 
do not allow 

fl

 ames, sparks, or lit tobacco 

to come near the battery. When charging or 
working near a battery, always cover your 
face and protect your eyes, and also provide 
ventilation.
•  Batteries contain sulfuric acid, which burns 

skin, eyes, and clothing.

•  Disconnect the battery before removing or 

replacing any electrical components.

 WARNING

Vehicle exhaust contains lethal fumes. 
Breathing these fumes, even in low 
concentrations, can cause death. Never 
operate a vehicle in an enclosed area without 
venting exhaust to the outside.

 WARNING

Gasoline is highly 

fl

 ammable and gasoline 

vapor is explosive. Never smoke while 
working on vehicle. Keep all open 

fl

 ames 

away from gasoline tank and lines. Wipe up 
any spilled gasoline immediately.

 CAUTION

Read instructions before assembling.
Fasteners should be 

fi

 nger tight until

instructed to tighten according to torque
chart. Use standard methods and practices
when attaching snowplow, including proper
personal protective safety equipment.
