IMPORTANT
Experience indicates that alcohol-blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads
to separation and formation 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 emptied before storage for 30
days or longer. Drain the gas tank, start the
engine and let it run unti_ the fuel lines and
carburetor are empty. Use fresh fuel next
season. See STORAGE section for addi-
tionat information.
A
WAR NIN G:
The chain must not
move
when the engine runs at idle speed. If the chain
moves at idle speed refer to CARBURETOR

contact with the muffler. A hot muffler can
cause serious bums.

switch to the STOP position.

back. Hold the handle and let the rope rewind
slowly. For cold weather starting, start the
unit at full choke; allow the engine to warm up
before squeezing the throttle trigger.
NOTE: Do not cut material with the choke/
fast idle lever at the FULL CHOKE position.
