OIL AND FUEL INFORMATION

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: For proper engine operation and 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.

NOTE: If your engine is damaged from insufficient lubrication, it voids the manufacturer's warranty. Straight gasoline in the unit also voids the warranty.

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.

MIXING RATIO - 40:1

+ UNLEADED GAS	2 CYCLE OIL
1 GALLON US (3.8 LITERS)	3.2 FL. OZ. (95 ml)
1 LITER	25 ml

WARNING: Gasoline is extremely flammable. Ignited Vapors may explode. Always stop the engine and allow it to cool before filling the fuel tank. Do not smoke while filling the tank. Keep sparks and open flames at a distance from the area.

WARNING: Remove fuel cap slowly to avoid injury from fuel spray. Never operate the unit without the fuel cap securely in place.

WARNING: Add fuel in a clean, well ventilated outdoor area. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for spilt fuel. Do not start the engine until fuel vapors dissipate.

NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations.

STARTING/STOPPING INSTRUCTIONS

STARTING A COLD ENGINE

WARNING: Operate this unit only in a well-ventilated outdoor area. Carbon monoxide exhaust fumes can be lethal in a confined area.

NOTE: To minimize the load on the engine during starting and warm-up, trim any excess trimming line. Leave about 5 inches (13 cm) of line from the cutting attachment (Fig. 5).

1. Mix gas with oil. Fill fuel tank with fuel/oil mixture. See Oil and Fuel Mixing Instructions.
2. Move the ignition switch to the Run position (Fig. 6).
3. Move choke lever to Position 1 (Fig. 7).
4. Prime the carburetor by fully pressing and releasing the primer bulb 10 times (Fig. 8).
5. Grip the handle firmly and press the safety trigger and press/squeeze the throttle trigger to the Full Throttle position (Fig. 6).
6. Pull the starter rope out a short way until you feel resistance (approximately 4'' ). Then continue with a smooth rapid pull (for a strong spark). Pull the rope briskly in this manner 4 times (Fig. 9).
7. Move the choke lever to Position 2.
8. With the throttle trigger still in the Full Throttle position, pull the starter rope 4 more times.
9. When the engine starts, leave the choke lever in Position 2 for about 10 seconds, so the unit can warm up.
10. Move the choke lever to Position 3. The trimmer is ready for use.

If engine fails to start, repeat everything from Step 2 on.

NOTE: Always pull the starter rope straight out. If you pull it at an angle, the rope will rub against the eyelet. This friction may cause the rope to fray a wear more quickly. Always hold the starter handle when the rope retracts. Never allow the rope to snap back from an extended position. This could damage the starter assembly or cause the rope to snag.

NOTE: Idling Information: in some cases due to operating conditions (extreme altitude, temperature, etc.), your unit may need a slight adjustment to its idle speed. If your unit does not idle after restarting two times, refer to Adjusting the Idle Speed.

STARTING A WARM ENGINE

1. Move the ignition switch to the Run position (Fig. 6).
2. Move choke lever to Position 1 (Fig. 7).
3. Grip the handle firmly and press/hold the safety trigger. Then press the throttle trigger to the Full Throttle position (Fig. 6).
4. Pull the starter rope briskly until the engine starts. Do NOT pull it more than 6 TIMES. Keep the throttle trigger at the Full Throttle position until the engine runs smoothly.

NOTE: If the engine doesn't start, place the choke in Position 3 and pull the starter rope 5 times. If the engine doesn't then start, the engine is probably flooded. Wait 5 minutes and then repeat the procedure with the choke in Position 3 and the throttle trigger in Full Throttle.

STOPPING ENGINE

To stop the unit, first release the throttle trigger. Let the engine return to idle. Move ignition switch to the "STOP STOP" position for stopping engine.

OPERATING INSTRUCTIONS

ADJUSTING TRIMMING LINE LENGTH

To release fresh line, run engine at full throttle and "bump" stringhead against lawn. Line will automatically release. The blade in debris shield will trim excess line (Fig. 10).

Fig. 10

WARNING: DO NOT use steel wire or plastic-coated steel wire of any kind with your stringhead. Serious operator injury can result.

CAUTION: Periodically remove wrapped weeds to prevent overheating the drive shaft. Weed wrap occurs when strands of weeds become entangled around the shaft beneath the debris shield (Fig. 11). This condition prevents the shaft from cooling properly. Remove weed wrap with a screwdriver or a similar device.

Fig. 11

TRIMMING PROCEDURES

NOTE: Even with care, trimming around foundations, brick or stone walls, curves, etc., will result in above normal string wear.

Trimming / Mowing

Swing trimmer with a sickle-like motion from side to side. Do not tilt the stringhead during the procedure. Test area to be trimmed for proper cutting height. Keep stringhead at same level for even depth of cut (Fig. 12).

Closer Trimming

Position trimmer straight ahead with a slight tilt so bottom of stringhead is above ground level and string contact occurs at proper cutting point. Always cut away from operator. Do not pull trimmer in toward operator.

Fence / Foundation Trimming

Approach trimming around chain link fences, picket fences, rock walls and foundations slowly to cut close without whipping string against the barrier. If the string comes in contact with rock, brick walls, or foundations, it will break or fray. If string snags fencing, it will snap off.

Trimming Around Trees

Trim around tree trunks with a slow approach so string does not contact bark. Walk around the tree trimming from left to right. Approach grass or weeds with the tip of the string and tilt stringhead slightly forward.

Fig. 12

Scalping

WARNING: Use extreme caution when scalping. Keep a distance of 100 feet (30 m) between operator, other people and animals during these operations.

Scalping refers to removal of all vegetation down to the ground. To do this, tilt the stringhead to about a 30 degree angle to the left. By adjusting the handle you will have better control during this operation. Do not attempt this procedure if there is any chance flying debris could injure operator, other people or cause damage to property.

WARNING: DO NOT sweep with trimmer. Sweeping refers to tilting stringhead to sweep away debris from walkways, etc. Your trimmer is a powerful tool and small stones or other such debris may be hurled 50 feet (15 m) or more, causing injury or damage to nearby property such as automobiles, homes and windows.

Fig. 13

MAINTENANCE AND REPAIR INSTRUCTIONS

WARNING: To prevent serious injury, never perform maintenance or repairs with unit running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure that the unit cannot start.

WARNING: Never use metal-reinforced line, wire, chain or rope. These can break off and become dangerous projectiles.
