• Gasoline is extremely flammable and is explosive under certain condition. KEEP OUT
OF
REACH
OF
CHILDREN.
• If the engine must
be
running
to
do some work, make sure the area is well-ventilated. Never run the engine in an
enclosed area. The exhaust contains poisonous carbon monoxide gas that may cause loss
of
the consciousness and
may lead
to
death. Run the engine in an open area or with an exhaust evacuation system in an enclosed area.
• Bending or twisting the control cables will impair smooth operation and could cause the cable
to
stick or bind, resulting
in loss of vehicle control.
• Work in a well ventilated area. Smoking or allowing flames or sparks in the work area or where gasoline is stored can
cause a fire or explosion.
CAUTION:
Be sure to remove the diaphragms before cleaning air and fuel passages with compressed air. The diaphragms might be
damaged.
• For fuel tank removal and installation, refer to Section 2.
• Before disassembling the carburetor, place an approved gasoline container under the carburetor drain tube, loosen the
carburetor drain screw and drain the carburetor.
• When disassembling the fuel system parts, note: the locations of the a-rings. Replace them with new ones on reassembly.
• After removing the carburetor, wrap the intake ports of the engine with a shop towel or cover them with a piece of tape
to prevent any foreign material from dropping into the engine. Be sure to remove the cover when reinstalling the
carburetor.
NOTE:
If the vehicle is to be stored for more than one month, drain the float bowls. Fuel left in the float bowls may cause clogged
lets resulting in hard starting or poor driveability.
