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.

0.020 in.

(0.5 mm)

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.
