fresh, clean, unleaded automotive gasoline. Capaci­
ty is one gallon. Replace fuel cap.
A
WARNING: DO NOT FILL CLOSER THAN
V2 INCH OF TOP OF FUEL TANK TO
PREVENT SPILLS AND TO ALLOW FOR
FUEL EXPANSION. IF GASOLINE IS
ACCIDENTLY SPILLED, MOVE CHIPPER-
SHREDDER AWAY FROM AREA OF
SPILL. AVOID CREATING ANY SOURCE
OF IGNITION UNTIL GASOLINE VAPORS
HAVE DISAPPEARED.
Caution: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and forma­
tion of acids during storage. Acidic gas can damage
the fuel system of an engine while in storage. To avoid
engine problems, the fuel system should be empty
before storage for 30 days or longer. Refer to “Storage”
section of this manual for details. Use fresh fuel each
season.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may result.
NOTE: USE CLEAN OIL AND FUEL. STORE IN AP­
PROVED, CLEAN, COVERED CONTAINERS. USE
CLEAN FILL FUNNELS.
