Maintenance (continued)
CLEANING
To avoid serious personal injury, always turn your
trimmer off and allow it to cool before you clean
or do any maintenance on it.
Use a small brush to clean off the outside of the unit.
Do not use strong detergents. Household cleaners that
contain aromatic oils such as pine and lemon, and such
as kerosene, can damage plastic housing or handle.
Wipe off any moisture with a soft cloth.
STORAGE
• Never store the unit with gasoline in the tank where
fumes may reach an open flame or spark.
• Allow the engine to cool before storing.
• Store the unit locked up to prevent unauthorized use
or damage.
• Store the unit in a dry, well ventilated area.
• Store the unit out of the reach of children.
LONG TERM STORAGE
If the unit will be stored for an extended time,
1. Drain all fuel from the gas tank into a container. Do
not use fuel that has been stored for more than 60
days. Dispose of the old fuel in accordance to
Federal, State, and Local regulations.
2. Start the engine and allow it to run until it stalls.
This ensures that all gasoline has been drained from
the carburetor.
3. Allow the engine to cool. Remove the spark plug
and put 1 oz. (30 ml) of high quality motor oil into
the cylinder. Pull the starter rope slowly to distribute
the oil. Reinstall the spark plug.
NOTE: Remove the spark plug and drain all of the
oil from the cylinder before attempting to start the
trimmer after storage.
4. Thoroughly clean the unit and inspect for any loose
or damaged parts. Repair or replace damaged parts
and tighten loose screws, nuts or bolts. The unit is
ready for storage.
TRANSPORTING
• Allow the engine to cool before transporting.
• Secure the unit while transporting.
• Drain the gas tank before transporting.
• Tighten gas cap before transporting.

REPLACING THE SPARK PLUG
Use a Champion RCJ6Y spark plug (or equivalent). The
correct air gap is 0.025 inch (0.655 mm). Remove the
plug after every 25 hours of operation and check its
condition.
1. Stop the engine and allow it to cool. Grasp the plug
wire firmly and pull the cap from the spark plug.
2. Clean dirt from around the spark plug. Remove the
spark plug from the cylinder head by turning a 5/8
inch socket counterclockwise.
3. Replace cracked, fouled or dirty spark plug. Set the
air gap at 0.025 inch (0.655 mm) using a feeler
gauge (Fig. 6-16).
Do not sand blast, scrape, or clean electrodes.
Grit in the engine could damage the cylinder.
4. Install a correctly gaped spark plug in the cylinder
head. Tighten by turning the 5/8 inch socket
clockwise until snug.
If using a torque wrench torque to:
110-120 in.•lb. (12.3-13.5 N•m).
Do not over tighten.
