OIL AND FUEL MIXING INSTRUCTIONS

Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

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 make fuel and oil separate. It forms acids when stored. When using alcohol-blended fuel, use fresh fuel (less than 60 days old).

Using Blended Fuels If you choose to use a blended fuel, or its use is

unavoidable, follow recommended precautions: , Always use the fresh fuel mix explained in your

operator's manual

, Always agitate the fuel mix before fueling the unit , Drain the tank and run the engine dry before storing

the unit

Using Fuel Additives The bottle of 2-cycle oil that came with your unit

contains a fuel additive which will help inhibit corrosion and minimize the formation of gum deposits. It is recommended that you use our 2-cycle oil with this unit.

If unavailable, use a good 2-cycle oil designed for air-cooled engines along with a fuel additive, such as STA-BIL Gas Stabilizer or an equivalent. 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 fuel tank.

CAUTION" Forproperengine

maximum reliability, pay strict attention to

the oil and fuel mixing instructions on the

2-cycle oil container. Using improperly mixed

fuel can severely damage the engine.

[] operation and

Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See the table below for specific gas and oil mixing

ratios.

NOTE: One gallon (3.8 liters) of unleaded gasoline mixed

with one 3.2 oz. (95 ml.) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio.

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable through the air filter/muffler cover (Fig. 29).

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 improper unit performance. 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 screw. Refer to

Air Filter Maintenance.

Adjust Idle Speed Screw

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.

Idle Speed Screw

WARNING: Thisunitwillneed

to be running during

idle speed adjustment. Wear protective clothing and observe all safety instructions

to prevent serious personal injury. Also, DO NOT set unit on any surface

except a clean, hard area while starting or performing any adjustments. Debris such

as gravel, sand, dust, grass, etc. could be picked up by the air intake and thrown out

by the discharge opening, damaging unit, property, or causing serious injury to

bystanders or operator.

If after checking the fuel mixture and cleaning the air filter the engine still will not idle, adjust the idle speed adjuster as follows.

1. Start the engine and let it run at the fast position for a minute to warm up.

2. Set the blower/vacuum mode change-over lever to the up position (Blower Mode). Refer to Operating as

a Blower.

NOTE: Setting the lever to the blower mode prevents the

vacuum bag from filling up while starting or running the unit.

3. Move the throttle control and let the engine idle. If the engine stops, insert a small phillips screwdriver into the hole in the air filter/muffler cover (Fig. 29). Turn the idle speed adjuster in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly.

4. If the unit appears to be idling too fast, turn the idle speed adjuster counterclockwise 1/8 of a turn at a

time (as needed), to reduce idle speed.

Fig. 29

REPLACING THE SPARK PLUG

Use a Champion RDJ7Y spark plug, or equivalent. The

correct air gap is 0.020 inch (0.5 ram). 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 ram) using a feeler gauge

(Fig. 30).

WARNING: Do not sand blast,

electrodes.Gritinthe engine could damage the cylinder.

4. Install a correctly-gapped spark plug in the cylinder

head. Tighten by turning the 5/8-inch socket

clockwise until snug.
