OIL AND FUEL INFORMATION

RECOMMENDED OIL TYPE

Using the proper type and weight of oil in the crankcase is extremely important. Check the oil before each
use and change the oil regularly. Failure to use the correct oil,
or using dirty oil, can cause premature engine wear and
failure.
Use a high-quality SAE 30 weight oil of API (American
Petroleum Institute) service class SF, SG, SH.

ADDING OIL TO CRANKCASE: INITIAL USE
NOTE: This unit is shipped without oil. In order to avoid

damage to the unit, put oil in the crankcase before

you attempt to start the unit.
Your unit is supplied with one 2.03 fluid oz. (60 ml.) bottle of
SAE 30 SF, SG, SH oil (Fig. 7).
NOTE: Save the empty oil bottle. It can be used to measure

the correct amount during future oil changes. See

Changing the Oil.

1. Unscrew the top of the bottle of oil and remove the

paper seal covering the opening. Replace the top. Next,
cut the tip off the funnel spout (Fig. 7).

2. Tip unit so that the back of the engine is facing up in a

vertical position.

3. Remove the oil fill plug from the crankcase (Fig. 8).

4. Pour the entire bottle of oil into the oil fill hole (Fig. 9).
NOTE: Never add oil to the fuel or fuel tank.

5. Wipe up any oil that may have spilled and reinstall the oil

fill plug.
Check oil before each use and change as needed. Refer to
Checking the Oil Level.

RECOMMENDED FUEL TYPE

Old fuel is the primary reason for improper unit performance.
Be sure to use fresh, clean, unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid damage

to the unit, do not mix oil with gasoline.

Definition of Blended Fuels

Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1% water in the fuel can form acids when stored. Use
fresh fuel (less than 60 days old), when using alcohol-blended fuel.

Using Blended Fuels

If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:

• Always use fresh unleaded gasoline

• Use a gas stabilizer fuel additive

• Drain tank and run the engine dry before storing unit

Using Fuel Additives

The use of a gas stabilizer will inhibit corrosion and minimize the formation of gum deposits. Using a fuel
additive can keep fuel from forming harmful deposits in the carburetor for up to six (6) months. Add 0.8 oz.
(23 ml.) of fuel additive per gallon of fuel according to the instructions on the container. NEVER add fuel
additives directly to the unit's gas tank.

Other Tips

• Assure the unit is not directed at anybody or any loose debris before starting the unit.

• Verify that the unit is in good working condition. Make sure the tubes are in place and secure.

• Always hold the unit securely when operating. Keep a firm grip on the handle.

• To reduce the risk of hearing loss associated with sound level(s), hearing protection is required.

• Operate power equipment only at reasonable hours— not early in the morning or late at night when
people might be disturbed. Comply with times listed in local ordinances. Usual recommendations are
9:00 am to 5:00 pm, Monday through Saturday.

• To reduce noise levels, limit the number of pieces of equipment used at any one time.

• To reduce noise levels, operate power blowers at the lowest possible speed to do the job.

• Check your equipment before operation, especially the muffler, air intakes and air filters.

• Use rakes and brooms to loosen debris before blowing.

• In dusty conditions, slightly dampen surfaces or use a mister attachment when water is available.

• Conserve water by using power blowers instead of
hoses for many lawn and garden applications, including
areas such as screens, patios, grills, porches, and
gardens.

• Watch out for children, pets, open windows or freshly
washed cars, and blow debris safely away.

• Clean up after using blowers and other equipment.
Dispose of debris appropriately.

• Use the blower for trees, shrubs, flower beds and hard­to-clean areas. Also use the unit around buildings, walls,
overhangs, fences and screens, and for other normal
cleaning procedures.

• Hold the blower with the right hand. Do not stand on
the right side of the blower when operating the unit (Fig.

15). If you do, you will be blocking the air intake and
this will affect the unit’s performance. Instead, be sure
to stand on the left side of the unit to maximize the
unit’s efficiency (Fig. 15).

MAINTENANCE AND REPAIR INSTRUCTIONS

7. Reinstall the air filter
cover. Position the
hooks on the right
side of the air filter
cover into the slots
at the right side of
the back plate (Fig.

25).

8. Swing the cover to
the left until the tab
on the air filter cover
snaps into place in
the slot on the back
plate (Fig. 26).

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable. An idle adjustment screw
is between the air filter cover and the engine starter housing (Fig. 27).
NOTE: Careless adjustments can seriously damage your unit. An

authorized service dealer should make carburetor adjustments.

Check Fuel

Old fuel is usually the reason for improper unit performance. Drain
and refill the tank with fresh 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. This is often mistaken for an out
of adjustment carburetor. Check the condition of the air filter before
adjusting the idle speed screw. Refer to Air Filter Maintenance.

Adjust Idle Speed Screw

If, after checking the fuel 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 at a high idle for a minute to
warm up. Refer to Starting/Stopping Instructions.

2. Release the throttle trigger and let the engine idle. If the engine
stops, insert a small phillips in between the Air Filter Cover and the
Engine Cover (Fig. 27). Turn the idle speed screw in, clockwise, 1/8
of a turn at a time (as needed) until the engine idles smoothly.

Checking the fuel, 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.

ROCKER ARM CLEARANCE

This requires disassembly of the engine. If you feel unsure or
unqualified to perform this, take the unit to a qualified service dealer.
NOTE: Inspect the valve to rocker arm clearance with a feeler

gauge after the first 10 hours of operation and every 40
hours of operation.

• The engine must be cold when checking or adjusting the rocker

arm clearance.

• This task should be performed inside, in a clean, dust free area.

1. Remove the 2 muffler cover screws with a flat blade or T-25
Torx head screwdriver (Fig. 28), then remove the cover.

2. Remove the 6 starter housing screws with flat blade or T-25
Torx head screwdriver (Fig. 28), then remove the housing.

NOTE: Make sure to store the screws so that they can be

reinstalled into their original holes.

3. Disconnect the spark plug wire.

4. Clean dirt from around the spark plug. Remove the spark plug from
the cylinder head by turning a 5/8 in. socket counterclockwise.

5. Clean dirt from around the rocker arm cover. Remove the
screw holding the rocker arm cover with a large flat blade
screwdriver or Torx T-25 bit (Fig. 29). Remove the rocker arm
cover and gasket.

6. Turn the flywheel slowly to bring the piston to the top of its
travel (known as top dead center). Check that:

• The piston is at the top of its travel while looking in the spark

plug hole (Fig. 29)

• Both rocker arms move freely, and both valves are closed.

If these statements are not true, repeat this step.

7. Slide the feeler gauge between the rocker arm and the valve return
spring. Measure the clearance between the valve stem and rocker
arm (Fig. 30 & 31). Measure both the intake and exhaust valves.

The recommended clearance for both intake and exhaust is .003 – .006 in. (.076 – 0.152 mm). Use a
standard automotive .005 in. (0.127 mm) feeler gauge. The feeler gauge should slide between the rocker
arm and valve stem with a slight amount of resistance, without binding. See Figures 30 and 31.

8. If the clearance is not within specification:

a. Turn the adjusting nut using a 5/16 inch (8 mm) wrench or nut

driver (Fig. 31).

• To increase clearance, turn the adjusting nut counterclockwise.

• To decrease clearance, turn the adjusting nut clockwise.

b. Recheck both clearances, and adjust as necessary.

9. Reinstall the rocker arm cover using a new gasket (Fig. 29).
Torque the screw to: 20–30 in•lb (2.2–3.4 N•m).

10. Check the spark plug and reinstall. See Replacing the Spark Plug.

11. Reinstall the spark plug wire.

12. Reinstall the engine cover. Check alignment of the cover before
tightening the screws. Tighten screws.

operation and check its condition.

1. Stop the engine and allow it to cool.

2. Remove the 2 plastic muffler cover screws with a flat blade or
T-25 Torx head screwdriver (Fig. 28), then remove the cover.

3. Remove the 2 plastic and 4 aluminum starter housing screws
with flat blade or T-25 Torx head screwdriver (Fig. 28), then
remove the housing.

NOTE: Make sure to store the screws so that they can be reinstalled into their original holes.

4. Grasp the plug wire firmly and pull the cap from the spark plug.

5. Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8
in. socket counterclockwise.

6. Replace cracked, fouled or dirty spark plug. Set the spark gap at 0.025 in. (0.635 mm.) using a feeler
gauge (Fig. 32).

7. Install a correctly-gapped spark plug in the cylinder head. Turn 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.
SPARK ARRESTOR MAINTENANCE

1. Remove the muffler cover. See Rocker Arm Clearance.

2. With a flat blade screwdriver or Torx T-20 bit and a T-25 bit,

remove the screws attaching the spark arrestor diverter to the
muffler (Fig. 33).
