MAINTENANCE AND REPAIR INSTRUCTIONS
AIR FILTER MAINTENANCE
WARNING:
To avoid serious personal injury, always turn the unit off and allow it to cool before
cleaning or servicing it.
Removing the Air Filter/Muffler Cover
1. Place the choke lever in Position 2.
NOTE: The choke lever must be in Position 2
(Fig. 12) to remove the air filter/ muffler
cover.
2. Remove the four (4) screws securing the air
filter/muffler cover (Fig. 12). Use a # T20 Torx
bit screwdriver.
3. Pull the cover from the engine. Do not force.
Cleaning the Air Filter
Clean and re-oil the air filter every 10 hours of
operation. It is an important item to maintain.
Failure to maintain your air filter properly can result
in poor performance or can cause permanent
damage to your engine.
1. Remove the air filter/muffler cover. Refer to the
Removing the Air filter/Muffler Cover
section.
2. Remove the air filter from inside the air
filter/muffler cover (Fig. 13).
3. Wash the filter in detergent and water (Fig. 14). Rinse the filter thoroughly.
Squeeze out excess water. Allow it to dry completely.
4. Apply enough SAE 30 oil to lightly coat the filter (Fig. 15).
5. Squeeze the filter to spread and remove extra oil (Fig. 16).
6. Replace the air filter inside the muffler cover (Fig. 13).
NOTE: Operating the unit without the air filter and cover assembly will VOID the
warranty.
Reinstalling the Air filter/Muffler Cover
1. Place the air filter/muffler cover over the back of the carburetor and muffler.
NOTE: The choke lever must be in Postion 2 (Fig. 12) to remove the air filter/ muffler cover.
2. Insert the four (4) screws into the holes in the air filter/ muffler cover (Fig. 12) and tighten. Use a # T20 Torx bit
screwdriver. Do not over tighten. Do not force.
SPARK ARRESTOR MAINTENANCE
1. Remove air filter/muffler cover. Refer to Removing the Air Filter/Muffler Cover.
2. Locate the muffler, but do not remove it. Find the screw on the bottom of the
muffler (Fig. 17). Remove the screw using either a torx #20 or flat blade
screwdriver.
3. Carefully pry up the left side spark arrestor hood. Two tabs act as hinges on the
right side of the hood. Flip open the spark arrestor hood like a door and then pull
its tabs out of the muffler slots.
4. Using a small flat blade screwdriver, carefully pry the spark arrestor screen out
from the inside of the spark arrestor hood.
5. Clean the spark arrestor screen with a wire brush. Replace it if it is damaged, or if you are unable to clean it
thoroughly.
6. Reinstall the spark arrestor screen snugly back into the spark arrestor hood.
7. Reinstall the two hood tabs into the two muffler slots and flip the spark arrestor hood closed.
8. Replace the screw you removed in Step 2 and tighten it securely.
9. Reinstall the air filter/muffler cover.
CARBURETOR ADJUSTMENTS
WARNING:
To avoid serious personal injury, always turn the unit off and allow it to cool before
cleaning or servicing it.
The engine's idle speed adjuster is adjustable through the air filter/muffler cover (Fig 18).
NOTE: Careless adjustments can seriously damage your unit. An authorized service dealer should make carburetor
adjustments.
Check Fuel Mixture
Old and/or improperly mixed fuel is usually the reason for the unit not running properly. Drain and refill the tank with
fresh, properly mixed fuel prior to making any adjustments. Refer to Oil and Fuel Information.
Clean Air Filter
The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict air flow and change the
air/fuel mixture. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before
adjusting the idle speed adjuster. Refer to Air Filter Maintenance.
Adjust Idle Speed Adjuster
WARNING:
The tines may spin during idle speed adjustments. Wear protective clothing and observe
all safety instructions to prevent serious personal injury.
If after checking the fuel mixture and cleaning the air filter the engine still will not idle, adjust the idle speed screw as
follows:
1. Start the engine and let it run for about 2-3 minutes at a high speed (full throttle)
to warm up. Refer to the Starting/Stopping Instructions.
NOTE: Ensure the tines are not in contact with the ground when adjusting the
idle.
2. Release the throttle control and let the engine idle. If the engine stops, insert a
small phillips screwdriver into the hole in the muffler cover (Fig. 18). Turn the idle
speed screw clockwise 1/8 of a turn at a time (as needed) until the engine idles
smoothly.
NOTE: The tines should not rotate during engine idle.
3. If the tines rotate when the engine idles, turn the idle speed screw counterclockwise 1/8 of a turn at a time
(as needed), to reduce idle speed.
Checking the fuel mixture, cleaning the air filter, and adjusting the idle speed screw should solve most engine
problems. If not and all 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 0.025 in. (0.635 mm). Remove the plug after
every 25 hours of operation to 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 in. socket counterclockwise.
WARNING: Do not sand blast, scrape or clean electrodes. Grit in the
engine could damage the cylinder.
NOTE: Replace a cracked, fouled or dirty spark plug.
3. Set the air gap at 0.025 in. (0.635 mm) using a feeler gauge (Fig. 19).
4. Install a correctly gapped spark plug in the cylinder head. Tighten by turning the
5/8 in. 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.
CLEANING THE UNIT
• Use a small brush to clean off the outside of the unit and to keep the air vents free of obstructions.
• Do not use strong detergents or petroleum based cleaners, like kerosene. Some household cleaners contain
aromatic oils such as pine and lemon that can damage the plastic housings or handles. 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 in a locked up area 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 to store the unit for an extended time:
1. Drain all fuel from the fuel 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 local regulations.
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 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 unit 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.
