Cleaning
Cleaning the Machine
Regular cleaning and washing will increase the life span of
the machine. Clean the machine after each use, before the
dirt hardens.
Ensure that the fuel tank cap and oil cap/dipstick are secure
to avoid getting water in the tank.
Use care when using a high-pressure sprayer because it can
damage warning decals, instruction signs, and the engine.
Important: Lubricate the trunnions after cleaning; refer
to Lubricating the Bearings and Seals (page 26).
Storage
Storing the Machine
For storage over 30 days, prepare the machine as follows:
1. Remove dirt and grime from the external parts of the
entire machine, especially the engine. Clean dirt and
debris from the outside of the engine cylinder-head
fins and blower housing.
Important: You can wash the machine with mild
detergent and water.
2. Condition the fuel system as follows:
A. Add a petroleum-based stabilizer/conditioner to
fuel in the tank. Follow the mixing instructions
from the stabilizer manufacturer. Do not use an
alcohol-based stabilizer (ethanol or methanol).
Important: Do not store
stabilizer/conditioned fuel over 90 days.
Note: Fuel stabilizer/conditioner is most
effective when mixed with fresh fuel and used at
all times.
B. Run the engine for 5 minutes to distribute the
conditioned fuel through the fuel system.
C. Stop the engine, allow it to cool, and drain the
fuel tank using a pump-type siphon. Dispose of
fuel properly; recycle it according to local codes.
D. Start the engine and run it until it stops.
E. Choke the engine.
F. Start and run the engine until it will not start again.
3. Clean the sediment cup; refer to Cleaning the Sediment
Cup (page 32).
4. Service the air cleaner; refer to Servicing the Air
Cleaner (page 27).
5. Change the engine crankcase oil; refer to Changing the
Engine Oil (page 28).
6. Remove the spark plug and check the condition; refer
to Servicing the Spark Plug (page 29).
7. Condition the engine as follows:
A. Remove the spark plug and pour 2 tablespoons
of engine oil into the spark-plug hole; refer to
Servicing the Spark Plug (page 29).
B. Pull the recoil-start handle slowly to crank the
engine and distribute the oil inside the cylinder.
C. Install the spark plug; refer to Servicing the Spark
Plug (page 29).
Note: Do not install the wire on the spark plug.
8. Grease the machine; refer to Lubricating the Bearings
and Seals (page 26).
9. Check and tighten all bolts, nuts, and screws. Repair or
replace any part that is damaged.
