CAUTION

Disconnect electric and/or hydraulic power

causing unit to not work properly.

Empty and clean after each use.

FUSES

The electrical system may contain several

automotive-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 re. Fuse

Be careful when using gasoline. Do not use gasoline

to clean parts. Store only in approved containers away

from sources of heat or ame.

CELL PHONES

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 road. Wait until it is safe to operate

mobile communication equipment such as cell phones,

text messaging devices, pagers, or two-way radios.

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.

Breathing these fumes, even in low

concentrations, can cause death. Never

operate a vehicle in an enclosed area without

venting exhaust to the outside.
