OIL AND FUEL INFORMATION

OIL AND FUEL MIXING INSTRUCTIONS

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.

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

+

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

MIXING RATIO - 40:1

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.

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.

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

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.

FUELING THE UNIT

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.

1.Remove the fuel cap.

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

2.Place the gas container’s spout into the fill hole on the fuel

tank (Fig. 16) and fill the tank. NOTE: Do not overfill the tank.

3.Wipe up any fuel that may have spilled.

4.Reinstall the fuel cap.

5.Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.

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

6.While squeezing the throttle lock-out and throttle control, pull the starter rope in a controlled and steady motion until the engine starts.

7.Keep the throttle lock-out and throttle control squeezed and allow the engine to warm up for 15 to 30 seconds.

NOTE: Engine may take longer to warm up and reach maximum operating speed at colder temperatures.

NOTE: Unit is properly warmed up when engine accelerates without hesitation.

8.Once the engine is warmed up, place the blue choke lever in Position 3 (Fig. 18). The unit is ready for use.

IF... the engine hesitates, return the blue choke lever to Position 2 (Fig. 18) and continue warm-up.

IF... the engine does not start, go back to step 2.

IF... the engine fails to start after a few attempts, place the blue choke lever in Position 3 and squeeze the throttle control. Pull the starter rope 3 to 8 times in a controlled and steady motion. The engine should start. If not, repeat.

IF WARM... If the engine is already warm, make sure the On/Off Stop control is in the ON position and start the unit with the blue choke lever in Position 2. After the unit starts, move the blue choke lever to Position 3.

OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

WARNING: Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit.

Before operating the unit, stand in the operating position (Fig. 20). Check for the following:

• The operator is wearing eye protection and proper clothing

• With a slightly-bent right arm, the operator’s hand is holding the shaft grip

• The operator’s left arm is straight, the left hand holding the D- handle

• The unit is at waist level

• The cutting attachment is parallel to the ground and easily contacts the grass without the need to bend over

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 21) while operating the trimmer at high speed.

NOTE: Always keep the trimming line fully extended. Line release

	becomes more difficult when the cutting line gets shorter.
	Each time the head is bumped, about 1 inch (25.4 mm) of trimming
	line releases. A blade in the cutting attachment shield will cut the
	line to the proper length if any excess line is released.	Fig. 20
	For best results, tap the bump knob on bare ground or hard soil. If
	you attempt a line release in tall grass, the engine may stall.
	Always keep the trimming line fully extended. Line release
	becomes more difficult when the cutting line gets shorter.
	NOTE: Do not rest the Bump Head™ on the ground while the unit
	is running.
	Some line breakage will occur from:
	• Entanglement with foreign matter
	• Normal line fatigue
	• Attempting to cut thick, stalky weeds
	• Forcing the line into objects such as walls or fence posts

TIPS FOR BEST TRIMMING RESULTS		Fig. 21

CAUTION: Do not remove or alter the line cutting blade assembly. Excessive line length will make the clutch overheat. This may lead to serious personal injury or damage to the unit.

•Keep the cutting attachment parallel to the ground.

•Do not force the cutting attachment. Allow the tip of the line to do the cutting, especially along walls. Cutting with more than the tip will reduce cutting efficiency and may overload the engine.

•Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.

•Cut from right to left whenever possible. Cutting to the left improves the unit's cutting efficiency. Clippings are thrown away from the operator.

•Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward-backward or side-to-side motion. Cutting shorter lengths produces the best results.

• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
• Following the trimming techniques
• What vegetation is being cut
• Where vegetation is cut
For example, the line will wear faster when trimming against a
foundation wall as opposed to trimming around a tree.
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all vegetation
around trees, posts, fences and more.
Rotate the whole unit so that the cutting attachment is at a 30°	Fig. 22
angle to the ground (Fig. 22).

USING THE CUTTING BLADE

WARNING: Always wear eye, hearing, foot, body protection and the shoulder strap to reduce the risk of injury when operating this unit.

WARNING: Do not use the cutting blade for edging or as an edger. Severe personal injury to yourself or others can result.

Before operating the unit with the cutting blade, stand in the operating position (Fig. 23). Refer to Holding the Trimmer.

Cutting Blade Operating Tips

To establish a rhythmic cutting procedure:

•Plant feet firmly, comfortably apart.

• Bring the engine to full throttle before entering the material to be cut. At full throttle the blade has maximum cutting power and is less likely to bind, stall or cause blade thrust (which can result in serious personal injury to the operator or others).

	WARNING: Blade thrust may occur when the	Fig. 23
	spinning blade contacts an object that it does
	not immediately cut. Blade thrust can be violent
	enough to cause the unit and/or operator to be
	propelled in any direction, and possibly lose
	control of the unit. Blade thrust can occur
	without warning if the blade snags, stalls or
	binds. This is more likely to occur in areas where
	it is difficult to see the material being cut.
	• Cut while swinging the upper part of your body from left to right	Fig. 24
	(Fig. 24).

•Always release the throttle trigger and allow the engine to return to idle speed when not cutting.

•When you are finished, always unsnap the unit from the harness before taking off the harness.

WARNING: The blade continues to spin after the engine is turned off. The coasting blade can seriously cut you if accidentally touched.

•Swing the unit in the opposite direction as the blade spins, which increases the cutting action.

•After the return swing, move forward to the next area to be cut plant your feet again.

•The cutting blade is designed with a second cutting edge. You can use it by removing the blade, turning it upside down, and reinstalling it.

WARNING: Do not sharpen the cutting blade. Sharpening the blade can cause the blade tip to break off while in use. This can result in severe personal injury to yourself or others. Replace the blade.

To reduce the chance of material wrapping around the blade, follow these steps:

•Cut at full throttle

•Swing the unit into material to be cut from your left to your right (Fig. 24)

•Avoid the material just cut as you make the return swing

WARNING: Do not clear away any cut material with the engine running or blade turning. To avoid serious personal injury, turn off the engine. Allow the blade to stop before removing materials wrapped around the blade shaft.

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable through the air filter/muffler cover (Fig. 40). 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

WARNING: The cutting attachment 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 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 screwdriver into the hole in the air filter/muffler cover (Fig. 40). Turn the idle speed screw in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly.

NOTE: The cutting attachment should not rotate when the engine idles.

3.If the cutting attachment rotates 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 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.

WARNING: To prevent serious personal injury, make sure the cutting attachment has stopped rotating before you turn it off and set it down.

REPLACING THE SPARK PLUG

WARNING: Do not sand blast, scrape or clean electrodes. Grit in the engine could damage the cylinder.

Use a Champion RDJ7Y spark plug (or equivalent). The correct air gap is 0.025 inch (0.635 mm). 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 in. socket counterclockwise.

3.Replace a cracked, fouled or dirty spark plug. Set the air gap at 0.025 in. (0.635 mm) using a feeler gauge (Fig. 41).

4.Install a correctly-gapped spark plug in the cylinder head. Tighten by turning the 5/8-inch 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

0.025 in.

(0.635 mm)

Fig. 41

WARNING: To avoid serious personal injury, always turn your unit off and allow it to cool before you clean or service it.

Use a small brush to clean off 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 housing or handle. Wipe off any moisture with a soft cloth.

STORAGE

•Never store the unit with fuel in the tank where fumes may reach an open flame or spark.

•Allow the engine to cool before storing.

•Store the unit locked up 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 the unit will be stored for an extended time, use the following storage procedure:

1.Drain all fuel from the fuel tank into a container with the same 2-cycle fuel mixture. Do not use fuel that has been stored for more than 60 days. Dispose of the old fuel/oil mix in accordance to Federal, State and 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 any high quality motor oil or 2-cycle 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 trimmer after storage.

4.Thoroughly clean the unit and inspect it for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.

•As the small off-road Lawn & Garden engine owner, you are responsible for performance of the required maintenance listed in your owner’s manual. MTD recommends that you retain all receipts covering maintenance on your Lawn & Garden Engine but MTD cannot deny warranty solely for the lack of receipts.

•As the small off-road Lawn & Garden engine owner, you should however be aware that the MTD may deny you warranty coverage if your fuel tank has failed due to abuse, neglect, or improper maintenance or unapproved modifications.

•You are responsible for presenting your Lawn & Garden fuel tank to MTD distribution center or service center as soon as the problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have a question regarding your warranty coverage, you should contact MTD at 1-800-949-4483.

Defects Warranty Requirements

(a)The warranty period begins on the date the engine or equipment is delivered to an ultimate purchaser.

(b)General Evaporative Emissions Warranty Coverage. The fuel tank must be warranted to the ultimate purchaser and any subsequent owner that the evaporative emission control system when installed was:

(1)Designed, built, and equipped so as to conform with all applicable regulations; and

(2)Free from defects in materials and workmanship that causes the failure of a warranted part for a period of two years.

(c)The warranty on evaporative emissions-related parts will be interpreted as follows:

(1)Any warranted part that is not scheduled for replacement as required maintenance in the written instructions must be warranted for the warranty period defined in subsection (b)(2). If any such part fails during the period of warranty coverage, it must be repaired or replaced by MTD. Any such part repaired or replaced under the warranty must be warranted for a time not less than the remaining warranty period.

(2)Any warranted part that is scheduled only for regular inspection in the written instructions must be warranted for the warranty period defined in subsection (b)(2). A statement in such written instructions to the effect of “repair or replace as necessary” will not reduce the period of warranty coverage. Any such part repaired or replaced under warranty must be warranted for a time not less than the remaining warranty period.

(3)Any warranted part that is scheduled for replacement as required maintenance in the written instructions must be warranted for the period of time prior to the first scheduled replacement point for that part. If the part fails prior to the first scheduled replacement, the part must be repaired or replaced by the MTD. Any such part repaired or replaced under warranty must be warranted for a time not less than the remainder of the period prior to the first scheduled replacement point for the part.

(4)Repair or replacement of any warranted part under the warranty provisions of this article must be performed at no charge to the owner at a warranty station.

(5)Not withstanding the provisions of subsection (4) above, warranty services or repairs must be provided at distribution centers that are franchised to service the subject engines or equipment.

(6)The owner must not be charged for diagnostic labor that leads to the determination that a warranted part is in fact defective, provided that such diagnostic work is performed at a warranty station.

(7)Throughout the evaporative emission control system’s warranty period set out in subsection (b)(2), MTD must maintain a supply of warranted parts sufficient to meet the expected demand for such parts.

(8)Manufacturer approved replacement parts must be used in the performance of any warranty maintenance or repairs and must be provided without charge to the owner. Such use will not reduce the warranty obligations of the manufacturer issuing the warranty.

(9)The use of any add-on or modified parts will be grounds for disallowing a warranty claim made in accordance with this article. The manufacturer issuing the warranty will not be liable under this Article to warrant failures of warranted parts caused by the use of an add-on or modified part.

(10)MTD shall provide any documents that describe the warranty procedures or policies within five working days of request by the Air Resources Board.
