DISPOSE OF FLUIDS PROPERLY
1. Observe relevant environmental protection regula-
tions when disposing of oil, fuel, coolant, electro-
lyte and other harmful waste. Never pour fluids into
the ground, down a drain, or into a stream, pond, or
lake.
C45W008A
VENTILATE WORK AREA
1. Exhaust contains poisonous carbon monoxide, so
you should never run the engine in a closed area. If
the engine must be running while performing
maintenance, make sure the area is well ventilated.
PREVENT ACID BURNS
1. Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill elec-
trolyte on yourself, flush with water, and get medi-
cal attention immediately.

To ensure safety and prevent damage to the machine
and surrounding equipment, heed the following pre-
cautions in handling electrical parts and wiring.
4. HANDLING PRECAUTIONS FOR ELECTRICAL PARTS AND WIRING
C45W111A
• Check electrical wiring for damage and loosened
connection every year. To this end, educate the
customer to do his or her own check. At the same
time recommend that the dealer performs a peri-
odic check during regular maintenance.
• Do not attempt to modify or remodel any electri-
cal parts and/ or wiring.
• When removing the battery cables, disconnect the
negative cable first. When installing the battery
cables, connect the positive cable first.

To avoid personal injury:
• Do not smoke while refueling.
• Be sure to stop the engine before refueling.
CAUTION
• Do not permit dirt or trash to get into the fuel
system.
• Be careful not to let the fuel tank become empty,
otherwise air will enter the fuel system, requiring
the fuel system to be bled before next engine start.
• Be careful not to spill during refueling. If a spill
should occur, wipe it off at once. Fuel on the trac-
tor may cause a fire.
• To prevent condensation( water) accumulation in
the fuel tank, fill the tank before parking the trac-
tor overnight.
