Engine failure due to improper air filter maintenance is not
covered by the product warranty.
Cleaning the Air Filter
1. Unscrew the cover rotary knob completely. Remove the
air filter cover from the air filter housing (Fig. 22).
2. Remove the air filter from the air filter housing.
3. Wash the air filter in detergent and water. Rinse the air
filter thoroughly and allow it to dry.
4. Reinstall the air filter in the air filter housing (Fig. 22).
NOTE:
Never forget to reintall the air filter. Operating the unit
without the air filter and air filter cover will VOID the
warranty.
5. Insert the tab on the air filter cover into the hole in the
air filter housing. Push the air filter cover back onto the
air filter housing. Insert the cover rotary knob into the air
filter cover. Tighten the cover rotary knob to secure the
air filter cover (Fig. 22). Do not overtighten as this may
strip the screw.
ADJUSTING THE IDLE SPEED
The cutting head will move when adjusting the idle speed.
Wear all protective clothing and keep all bystanders,
children, and pets at least 50 ft. away. Make adjustments
with the unit supported by hand so that the cutting head
does not contact the ground or any object.
Keep all parts of your body away from the cutting head and
muffler. Failure to follow these instructions could result in
serious personal injury.
If the engine will not idle properly:
1. Start the engine. Refer to "STARTING INSTRUCTIONS"
and "STOPPING INSTRUCTIONS".
2. Release the throttle control and let the engine idle.
•
If the engine stops, increase the idle speed. Use a
small Phillips screwdriver to turn the idle speed screw
clockwise, 1/8 of a turn at a time, until the engine idles
smoothly (Fig. 23).
•
If the cutting head spins when the engine idles,
reduce the idle speed. Turn the idle speed screw
counterclockwise, 1/8 of a turn at a time, until the cutting
head stops moving (Fig. 23).
WARNING:
The cutting attachment should never turn at idle.
Turn the idle speed screw counterclockwise
to reduce the idle RPM and stop the cutting
attachment, or contact customer support for
adjustment and discontinue use until the repair
is made. Serious personal injury could result
from the cutting attachment turning at idle.

MAINTAINING THE SPARK PLUG
1. Stop the engine and allow it to cool. Grasp the spark
plug boot firmly and pull it from the spark plug.
2. Clean around the spark plug. Remove the spark plug
from the cylinder head with a 5/8-inch socket, turning
counterclockwise.
WARNING:
Do not remove the spark plug when the engine
is hot. Never sand blast, scrape or clean spark
plug electrodes. Grit in the engine could damage
the cylinder.
3. Inspect the spark plug. If the spark plug is cracked,
fouled or dirty, replace it with replacement part #AM5C
or an equivalent spark plug.
4. Use a feeler gauge to set the air gap at 0.6 mm - 0.8
mm (0.025 in. - 0.031 in.) (Fig. 24).
5. Install the spark plug in the cylinder head. Tighten the
spark plug with a 5/8-inch socket spanner, turning it
clockwise until snug.
NOTE:
If using a torque wrench, torque to 18 N•m (159 in.•lb.). Do
not over tighten.
6. Reattach the spark plug boot.
CLEANING
To avoid serious personal injury, always stop the engine and
allow it to cool before cleaning or maintaining the unit.
Use a small brush to clean 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. 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.
• 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.
Short-term Storage (1-2 weeks)
Store the unit in a horizontal position. If not possible, store
the unit vertically with the engine at the top.
