Engine
WARNING
• Operate the saw in well-ventilated
areas. Concentrated engine exhaust
can cause loss of consciousness
and/or death.
• DO NOT touch the engine/muffler assembly
with the engine running, and always let the
parts cool down prior to touching them.
• DO NOT use any starter substances
or starter fluids when starting the
engine using a glow plug (e.g.,
starter fluid sprayed into the air
filter). These materials are extremely
flammable and explosive, and can melt parts
or possibly explode when used to help start the
engine.
