INSTRUCTIONS

MODELS

IMPORTANT: Do not start this engine before
reading Section 1 and Section 2 of this manual.

CAUTION

PROVIDE EFFICIENT VENTILATION. Exhaust gases contain carbon monoxide, an odorless and deadly poison. Do not operate engine in an enclosed area.

KEEP ENGINE CLEAN. This engine is air-cooled. If cooling system becomes clogged, serious damage may result. Therefore, keep the blower screen, fins on flywheel, cylinder head and block free from grass or dirt.

SECTION 1
BEFORE STARTING

“OIL-FOAM”®AIR CLEANER

“Oil-Foam” air cleaners are oiled at the factory and do not require initial service.

FILL FUEL TANK

Use clean, fresh “regular” grade gasoline. Fill tank completely.

DO NOT FILL GASOLINE TANK WHILE ENGINE IS RUNNING. Avoid spilling gasoline on a hot engine — this may cause an explosion and serious injury.
