 CAUTION

Batteries normally produce explosive gases, 

which can cause personal injury. Therefore, 

do not allow flames, 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.

 CAUTION

Read instructions before assembling. 

Fasteners should be finger tight until 

instructed to tighten according to torque 

chart. Use standard methods and practices 

when attaching snowplow, including proper 

personal protective safety equipment.

 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 flammable and gasoline 

vapor is explosive. Never smoke while 

working on vehicle. Keep all open flames 

away from gasoline tank and lines. Wipe up 

any spilled gasoline immediately.
