Storing Your Engine

Short-Term/Seasonal Storage
Clean Engine
If the engine has been running, allow it to cool for at least half an
hour before cleaning.
Before servicing the engine, remove the carburetor cover and/or
blower housing. Discard the dirt and debris from the following
areas:
• Cooling Fins
• Air Intake Screen or Recoil Starter/Flywheel
Guard Areas
• Spark Plug Connection
• Levers
• Linkage Area
• Guards
• Carburetor
• Head
Removing debris will insure adequate cooling, correct engine
speed and reduce the risk of fire.
NOTE: Do not spray engine with water to clean because water
could contaminate fuel. Using a garden hose or pressure washing
equipment can also force water into the air cleaner or muffler
opening. Water in the air cleaner will soak the paper element,
and water that passes through the element or muffler can enter
the cylinder, causing damage.
WARNING!
Accumulation of debris around muffler
could cause a fire. Inspect and clean before every
use.
