CLEANING AND STORAGE
CLEANING
1. Loosen the saw chain if the chain tension was adjusted during
operation. The saw chain will contract as the unit cools, which
could damage the unit if the chain is too tight.
2. Clean the unit with a damp cloth. Do not douse the unit with
water. Do not use strong detergents. Household cleaners that
contain aromatic oils such as pine and lemon, and solvents such
as kerosene, can damage plastic.
NOTE: When preparing the unit for long-term storage (30 days or
more), remove the guide bar and saw chain. Carefully clean the
guide bar cover, guide bar mounting surface and sprocket. Use
a firm non-wire brush to clean the guide bar groove.
Reassemble the unit.
3. Wipe off any moisture with a soft cloth.
4. Use compressed air, up to 40 PSI, to blow debris from the
cylinder fins (Fig. 47). The cylinder fins must be cleaned on a
regular basis to reduce the risk of personal injury or damage to
the unit as a result of fire. Always use safety goggles/glasses
when using compressed air. Do not use water or other liquids to
clean the cylinder fins. Use a small wire brush to remove
stubborn debris. If a significant amount of debris remains, have
the unit cleaned by an authorized service dealer.
5. Lightly coat the guide bar and saw chain with a corrosion-
inhibiting oil.
STORAGE
• Loosen the saw chain if the chain tension was adjusted during
operation. The saw chain will contract as the unit cools, which
could damage the unit if the chain is too tight.
• Allow the engine to cool before storing.
• Thoroughly clean the unit and inspect it for any loose or
damaged parts. Repair or replace damaged parts and tighten
loose screws, nuts or bolts.
• Cover the guide bar and saw chain with the scabbard.
• Never store a fueled unit where fumes may reach an open flame
or spark.
• Lock up the unit to prevent unauthorized use or damage.
• Store the unit in a dry, well-ventilated area.
• Store the unit out of the reach of children.
NOTE: It is normal for bar and chain oil to seep from the unit when
not in use. Please take this into consideration when storing the
unit.
Long-term Storage (30 days or more)
1. Remove the fuel cap, tip the unit and drain the fuel into an
approved container. Reinstall the fuel cap.
2. Start the engine and allow it to run until it stalls. This ensures
that all fuel has been drained from the carburetor.
3. Allow the engine to cool. Remove the spark plug and put 5 drops
of any high quality motor oil or 2-cycle oil into the cylinder. Pull the
starter rope slowly to distribute the oil. Reinstall the spark plug.
Preparing the Unit for Use after Long-term Storage
1. Remove the spark plug and drain all of the oil from the cylinder.
NOTE: Do not use fuel that has been stored for more than 30 days.
Dispose of old fuel according to federal, state and local regulations.
WARNING:
To avoid serious personal injury, always stop
the engine and allow it to cool before cleaning or maintaining
the unit.
