CLEANING
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
solvents such as kerosene, can damage plastic housing
or handle. Wipe off any moisture with a soft cloth.
STORAGE
• Never store a fueled unit 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 you plan on storing the unit for an extended time, use
the following storage procedure:
1. Drain all petrol from the petrol tank into a container
with the same 2-cycle petrol mixture. Do not use
petrol that has been stored for more than 60 days.
Dispose of the old petrol/oil mix in accordance to
Federal, State and Local regulations.
2. Start the engine and allow it to run until it stalls. This
ensures that all petrol has been drained from the
carburetor.
3. Allow the engine to cool. Remove the spark plug and
put 1 oz. (30 ml) 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.
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 it 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.
• Drain petrol from unit.
• Tighten petrol cap before transporting.
• Secure the unit while transporting.
WARNING: To avoid serious personal injury,
always turn your trimmer off and allow it to
cool before you clean or service it.
2. Release the throttle trigger and let the engine idle. If the
engine stops, insert a small phillips or flat blade
screwdriver into the hole in the air filter/muffler cover (Fig.
28). Turn the idle speed screw in, clockwise, 1/8 of a
turn at a time (as needed) until the engine idles smoothly.
3. If the engine appears to be idling too fast, turn the
idle speed screw counterclockwise 1/8 of a turn at
a time (as needed), to reduce idle speed.
Checking the petrol mixture, cleaning the air filter, and
adjusting the idle speed should solve most engine
problems. If not and all of the following are true:
• the engine will not idle
• the engine hesitates or stalls on acceleration
• there is a loss of engine power
Have the carburetor adjusted by an authorized service dealer.
REPLACING THE SPARK PLUG
Use a Champion RDJ7Y spark plug, or equivalent. The
correct air gap is 0.020 inch (0.5 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 it from the spark plug.
2. Clean around the spark plug. Remove the spark plug
from the cylinder head by turning a 5/8-inch socket
counterclockwise.
3. Replace a cracked, fouled or dirty spark plug. Set the air
gap at 0.020 in. (0.5 mm) using a feeler gauge (Fig. 29).
4. Install a correctly-gapped 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.

CAUTION: Do not sand blast, scrape or
clean electrodes. Grit in the engine could
damage the cylinder.
WARNING: To prevent serious personal
injury, make sure the cutting attachment
has stopped rotating when it is turned off
and you set it down.
