SAFETY RULES

THESE SAFETY RULES ARE FOR YOUR PROTECTION. READ THEM CAREFULLY.

IMPORTANT

Safety standardsrequire operator presence controls to minimize the risk of injury. Your Edger/ Trimmer is equipped with such controls. Do not attempt to defeat the function of the operator presence control under any circumstances.

Look for this symbol to point out important safety precautions. It means ATTENTION!!! BECOME ALERT!!! YOUR SAFETY IS INVOLVED.

BEFORE USE

• Read the owner’s manual carefully. Be thoroughly

familiar with the controls and the proper use of the Edger/Trimmer. Know how to stop the Edger/Trimmer and disengage the controls quickly.

• Do not operate the Edger/Trimmer without wearing

adequate outer garments. Wear footwear that will improve footing on slippery surfaces.

• Keep the area of operation clear of all persons,

particularly small children and pets.

• Thoroughly inspect the area where the Edger/Trim-

mer is to be used and remove all foreign objects.

FUEL SAFETY

• Handle fuel with care; it is highly flammable.

• Use an approved container.

• Check fuel supply before each use, allowing space

for expansion as the heat of the engine and/or sun can cause fuel to expand.

• Fill fuel tank outdoors with extreme care. Never fill

fuel tank indoors. Replace fuel tank cap securely and wipe up spilled fuel.

• Never remove the fuel tank cap or add fuel to a

running or hot engine.

• Never store fuel or Edger/Trimmer with fuel in the

tank inside a building where fumes may reach an open flame.

OPERATING SAFETY

• Never allow children or young teenagers to

operate the Edger/Trimmer. Keep them away while iti s operating. Never allow adults to operate the Edger/Trimmer without proper instruction.

• Always wear safety glasses or eye shields during

operation or while performing an adjustment or repair to protect your eyes from foreign objects that may be thrown from the Edger/Trimmer.

• Do not put hands or feet near or under rotating

parts.

• Exercise extreme caution when operating on or

crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic.

• Exercise caution to avoid slipping or falling.

• Never operate the Edger/Trimmer without proper

guards, plates, or other safety protective devices in place.

• Never operate the Edger/Trimmer at high transport

speeds on slippery surfaces. Look behind and use care when backing.

• Never allow bystanders near the Edger/Trimmer.

• Keep children and pets away while operating.

• Never operate the Edger/Trimmer without good

visibility or light.

• Do not run the engine indoors. The exhaust fumes

are dangerous (containing CARBON MONOXIDE, an ODORLESS and DEADLY GAS).

• Take all possible precautions when leaving the

Edger/Trimmer unattended. Stop the engine.

• Do not overload Edger/Trimmer capacity by at-

tempting to edge too deep at too fast a rate.

SAFE STORAGE

• Always refer to the Owner's Manual instructions for

important details if the Edger/Trimmer is to be stored for an extended period.

• Never store the Edger/Trimmer with fuel in the fuel

tank inside a building where ignition sources are present such as water and space heaters, clothes dryers, and the like. Allow the engine to cool before storing in any enclosure.

• Keep the Edger/Trimmer in safe working condition.

Check all fasteners at frequent intervals for proper tightness.

FUEL SAFETY

• After striking a foreign object, stop the engine

(motor). Remove the wire from the spark plug, and keep the wire away from the plug to prevent accidental starting. Thoroughly inspect the Edger/Trimmer for any damage, and repair the damage before restarting and operating the Edger/Trimmer.

• If the Edger/Trimmer should start to vibrate abnor-

mally, stop the engine (motor) and check immedi- ately for the cause. Vibration is generally a warning of trouble.

• Stop the engine (motor) whenever you leave the

operating position. Also, disconnect the spark plug wire before unclogging the blade and when making any repairs, adjustments, or inspections.

• When cleaning, repairing, or inspecting, shut-off

the engine (motor) and make certain all moving parts have stopped.

• Never attempt to make any adjustments while the

engine (motor) is running (except when specifically recommended by the manufacturer).

NOTE

warm engine after a short shutdown.

• To start engine, grasp the engine starter handle firmly with your right hand.

• Hold the handle firmly with your left hand.

• Pull up sharply on the recoil starter handle. DO NOT allow the starter rope to snap back, let it rewind slowly while holding the starter handle. If engine fails to start after three pulls, push primer button two times and pull starter rope again.

• When the engine starts, push throttle

control lever up to increase speed; down to decrease speed. Run at full engine speed during normal use.

NOTE: The cutting blade speed is controlled by the engine speed. To reduce the cutting blade speed, push down on the throttle control lever. To increase the blade speed, push the throttle control lever up.

• To stop the engine, make sure the clutch

lever is all the way back or up and move the throttle control lever to the STOP position.

CAUTION: Never run the engine in-

doors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas. Keep hands, feet, hair and loose clothing away from any moving parts on the engine or edger/trimmer. Avoid the muffler and surrounding areas. Temperatures may exceed 150° F.

EDGING TIPS

• Edging is best performed when conditions are dry. If the soil is to wet, dirt becomes packed in and around the blade causing premature belt wear and decreased performance.

• If dirt does become packed around the blade, stop the engine, remove the spark plug wire, and remove the packed debris before continuing to edge. Always wear gloves when working on blade.

• If very deep edging is required, we recommend that a shallow cut be made first, then cuts at greater depth until the desired depth is obtained.

• Uniform edging can be performed when the blade guide rides on and against the surface which you are edging.

• Edging can be customized by varying the number of passes and by the distance your blade is from the surface you are edging.

The carburetor shown below has been pre-set at the factory and readjustment should not be necessary. If you think your carburetor needs

CAUTION: Never store your Edger/

Trimmer indoors or in an enclosed, poorly ventilated area. If gasoline remains in the tank fumes may reach an open flame, spark or pilot light from a furnace, water heater, clothes dryer, cigarette, etc. and ignite.

EDGER/TRIMMER

• Clean the Edger/Trimmer thoroughly;

remove all debris and wipe the unit dry.

• Inspect the Edger/Trimmer for worn or damaged parts and tighten all loose hardware.

• Oil all points described in the Lubrication paragraph in the Maintenance section of this manual.

• Store the Edge/Trimmer in a protected area and cover for additional protection.

IMPORTANT

: A yearly checkup or tune-

up by a Service Center is a good way of ensuring that your Edger/Trimmer will provide maximum performance for the next season.

ENGINE

IMPORTANT: It is important to prevent pre-

vent gum deposits from forming in essential fuel system parts such as the carburetor, fuel filter, fuel hose, or tank during storage. Also, experience indicates that alcohol-blended fuels called gasohol or using ethanol or methanol can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.

adjusting, see your nearest Authorized Service Center.

IMPORTANT

: Never tamper the engine

governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed setting can be dangerous. If you think the engine-governed high speed needs adjusting, contact your nearest Service Center which has the proper equipment and experience to make any necessary adjustments.

STORAGE

To prevent engine damage (if Edger/Trimmer is not used for more than 30 days)follow the

steps below.

• To remove gasoline, run the engine until the tank is empty and the engine stops.

• If you do not want to remove gasoline, a fuel stabilizer may be added to any gasoline left in the tank to minimize gum deposits and acids. If the tank is almost empty, mix stabilizer with fresh gasoline in a separate container and add some to the tank. Always follow instructions on stabilizer container. Then run engine at least 10 minutes after stabilizer is added to allow mixture to reach carburetor. Store Edger/Trimmer in a safe place. See IMPORTANT under STORAGE (ENGINE).

• Store the Edger/Trimmer in the wheelsdown, operating position. If the Edger/ Trimmer is stored in any other position, oil from the crankcase could enter the cylinder, causing a service problem.

• You can keep your engine in good oper-

ating condition during storage by:

• Changing oil.

• Lubricating the piston/cylinder area. This

can be done by first removing the spark plug and squirting clean engine oil into the spark plug hole. Then cover the spark plug hole with a rag to absorb oil spray. Next, rotate the engine by pulling the starter two or three times. Finally,reinstall spark plug and attach spark plug wire.

• Spray a light oil around the top of the tube

the quill rod extends through and work the oil in with the clutch lever. This will prevent the quill assembly from sticking to the tube next season.
