CARBURETOR
The carburetor of your generator is pre-set at the fac-
tory. The carburetor should not be tampered with. If your
generator is used at an altitude in excess of 4000 feet
performance may be affected. If so consult with your
nearest Craftsman Service Center regarding high altitude
set changes.
GOVERNOR
Your engine governor maintains the constant operating
speed of your generator. DO NOT tamper with the en-
gine governor which is factory set for proper engine
speed.
Low engine speeds impose a
heavy load on the engine and
when sufficient power is not available the engine
life could be shortened.
SERVICE ADJUSTMENTS
Over-speeding your engine above factory high speed set-
ting can be dangerous and could possibly cause per-
sonal injury or property damage. If you believe the en-
gine is running too fast or slow, take your generator to a
Authorized Craftsman Service Center for repair and ad-
justment.
Clean Cooling System
Debris may clog engine's air cooling system, espe-
cially after prolonged operation. Internal cooling fins
and surfaces may require cleaning to prevent over-
heating and engine damage. Remove blower housing
and clean.
