• Carefully plan your operation in advance. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path.

• All stick edger service, other than the operations shown in the present manual, have to be performed by competent personnel.

• The stick edger must only be used for trimming grass vertically, i.e. for edging grass surfaces. It is unadvisable to cut other types of material or to grass in a horizontal plane or for cutting hedges.

• It is unadvisable to hitch tools or applications to the P.t.o. that are not specified by the manufacturer.

Fuel Handling

WARNING: Gasoline is an extremely flammable fuel. Use extreme caution when handling gasoline or fuel mix. Do not smoke or bring any fire or flame near the fuel or the stick edger (Fig. 7).

WARNING: Fuel and fuel fumes can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

WARNING: Beware of carbon monoxide poisoning.

• To reduce the risk of fire and burn injury, handle fuel with care. It is highly flammable.

• Mix, store and transport fuel in a container approved for gasoline (Fig. 8).

• Mix fuel outdoors where there are no sparks or flames.

• Select bare ground, stop engine, and allow to cool before refuelling.

• Loosen fuel cap slowly to release pressure and to keep fuel from escaping around the cap.

• Tighten fuel cap securely after refuelling. Unit vibration can cause an improperly tightened fuel cap to loosen or come off and spill quantities of fuel.

• Wipe spilled fuel from the unit and allow remaining fuel to evaporate. Move 10 feet (3 m) away from refuelling site before starting engine (Fig. 9).

• Never attempt to burn off spilled fuel under any circumstances.

• Do not smoke while handling fuel or while operating the stick edger.

• Store fuel in a cool, dry, well ventilated place.

Fueling (Do Not Smoke!) (Fig. 22)

This product is powered by a 2-cycle engine and requires pre-mixing gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-cycle engine oil in a clean container approved for gasoline

(Fig. 20). RECOMMENDED

FUEL: THIS ENGINE IS CERTIFIED TO

OPERATE ON UNLEADED GASOLINE INTENDED FOR AUTOMOTIVE USE WITH AN OCTANE RATING OF 89 ([R + M] / 2) OR HIGHER (Fig. 21). Mix 2-Cycle Engine Oil with gasoline according to the instructions on the package. We strongly recommend the use of 2% (1:50) Efco Two Cycle Engine Oil, which is specifically formulated for all Efco air-cooled two-stroke engines. The correct oil / fuel proportions shown in the table below are suitable when using the Efco Two Cycle Engine Oil or an equivalent high-quality engine oil (JASO specification FD or ISO specifi- cation L-EGD). When oil specifications are NOT equivalent or unknown use 4%

(1:25) oil / fuel mixing ratio.

CAUTION: DO NOT USE AUTOMOTIVE OIL OR 2-CYCLE OUTBOARD OIL.

CAUTION: Never use a fuel with an alcohol percentage higher than 10%. Gasohol with up to 10% alcohol or E10 fuel are acceptable.

When using an oxygenated gasoline a good practice of fuel management is necessary. Gasoline oxygenated with alcohol readily takes up water when it is present; the water may be condensed out of humid air or be a contaminant in the fuel system, including tank.

CAUTION:

- Match your fuel purchases to your consumption; don’t buy more than you will use in one or two months;

- Store gasoline in a tightly-closed container in a cool, dry place.

The use of oxygenated gasoline may cause the occurrence of vapor-lock easier.

NOTE: 2-Cycle Engine Oil contains a fuel stabilizer and will stay fresh up to 30 days. DO NOT mix quantities larger than usable in a 30 day period. A 2-cycle oil containing a fuel stabilizer is recommended.

WARNING: Avoid cutting close to fences, sides of buildings, tree trunks, stones or other such objects that could cause the stick edger to kick back or could cause damage to the blade. In addition, be alert to an increased possibility of ricochets in such situations.

WARNING: The stick edger is normally to be used at ground level with the cutting attachment perpendicular to the ground. Use of a stick edger above ground level or with the cutting attachment parallel to the ground may increase the risk of injury, since the cutting attachment is more fully exposed and the stick edger may be more difficult to control. Never use your stick edger as a hedge trimmer.

WARNING: If the blade loosens after being properly tightened, stop work immediately. The retaining nut may be worn or damaged and should be replaced. Never use unauthorized parts to secure the blade. If the blade continues to loosen, see your dealer. Never use a stick edger with a loose blade.

Look around or otherwise check for the presence and locations of other people working so as to maintain a distance between each person sufficient to ensure safety.

Basic Cutting Procedure

1. Wear non-slip gloves for maximum grip and protection.

WARNING: Hold the stick edger firmly with both hands (Fig. 25). Always keep your body to the left of tube. Never use a cross-handed grip. Left-handers should follow these instructions too. Keep a proper cutting stance (Fig. 26).

2. Maintain a proper grip (Fig. 25) on the stick edger whenever the

engine is running. The fingers should encircle the handlebar and the thumb is wrapped under the handlebar.

Work Area Precautions

WARNING: Cut only grass or weed. Do not cut metal, plastics, masonry, or non-wood building materials. Do not cut wood.

• Never allow children to operate your stick edger. Only allow others to use this stick edger who have read this Operator's Manual or received adequate instructions for the safe and proper use of this stick edger.

• Keep everyone - helpers, bystanders, children, and animals at a safe distance from the cutting area (Fig. 27). During operations, keep a minimum distance of 50 feet (15 m) between workers.

• Always cut with both feet on solid ground to prevent being pulled off balance.

• Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly.

• Do not cut above chest height, as a stick edger held higher is difficult to control against kickback forces.

• Do not work near electrical wires. Leave this operation for professionals.

• Cut only when visibility and light are adequate for you to see clearly.

• Do not cut from a ladder, this is extremely dangerous.

• Stop the stick edger if the blade strikes a foreign object. Inspect the stick edger and repair parts as necessary.

• Even a small amount of dirt will quickly dull a blade and increase the possibility of kickback.

• Stop the engine before setting the stick edger down.

• Be particularly cautious and alert while wearing hearing protection because such equipment may restrict your ability to hear sounds indicating danger (calls, signals, warnings, etc).

• Be extremely cautious when working on slopes or uneven ground.

WARNING: Never use rigid blades when cutting in stony areas.Thrown objects or damaged blades may result in serious or fatal injury to the operator or bystanders. Watch out for thrown objects. Always wear approved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 50 ft (15 m). Stop the machine immediately if anyone approaches. Never swing the machine around without first checking behind you to make sure no-one is within the safety zone.

WARNING: Never cut when visibility is poor or in very high or low temperatures or in freezing weather.

Starting The Engine

WARNING:When the engine is started with the choke in either the choke or start throttle positions the cutting attachment will start to rotate immediately.

• Place the stick edger on level ground and ensure that no objects or obstructions are in immediate vicinity which could come in contact with the cutting attachment. Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot!), see Fig. 28.

• Slowly push the purge bulb 6 to 8 times (A, Fig. 29).

• Move the on/off switch (B, Fig. 30) to the start position “I”.

• Pull the choke lever (D, Fig. 31-32) in the CLOSE position. The half-throttle is automatically set when choke lever is set at CLOSE.

OPERATION

• Pull the starter rope (Fig. 28) until the first firing of the engine is heard (no more than five (5) pulls). A new unit may require additional pulls.

• Never wrap the starter cord around your hand.

• When the engine starts, wait for about 5-10 seconds and then pull the throttle lever (C, Fig. 30), the choke lever (D, Fig. 31-33) will return automatically to the original “OPEN” position.

• When pulling the starter rope, do not use the full extent of the rope as this can cause the rope to break. Do not let starter rope snap back. Hold the handle and let the rope rewind slowly.

WARNING: Do not cut material with the choke/fast idle lever at the CLOSE position. Do not operate your stick edger with the starting throttle lock engaged. Cutting with the starting throttle lock engaged does not permit the operator proper control of the stick edger.

NOTE - STARTING WARM ENGINE: Follow above starting instructions, but do not use the CLOSE position for start up again.

WARNING: Weather conditions and altitude may affect carburetion. Do not allow bystanders close to the stick edger while adjusting the carburetor.

Keep the engine at full throttle the entire time you are cutting.

NOTE: It is normal for smoke to be emitted from a new engine during and after first use.

Breaking-in the Engine

The engine reaches the maximum power after 5-8 hours of activity. During this period of breaking-in do not make the machine function idly at full throttle, to avoid excessive functioning stress.

CAUTION! – During the breaking-in period do not vary the carburetion to obtain a presumed power increment; the engine can be damaged.

Difficult Starting (or starting a flooded engine)

The engine may be flooded with too much fuel if it has not started after 10 pulls. Flooded engines can be cleared of excess fuel by following the warm engine starting procedure listed above. Ensure the ON/STOP switch is in the ON position. Starting could require pulling the starter rope handle many times depending on how badly the unit is flooded. If engine fails to start refer to the TROUBLESHOOTING TABLE (page 28).

Engine is Flooded

• Set the on/off switch to STOP.

• Engage a suitable tool in the spark plug boot (Fig. 34).

• Pry off the spark plug boot.

• Unscrew and dry off the spark plug.

• Open the throttle wide.

• Pull the starter rope several times to clear the combustion chamber.

• Refit the spark plug and connect the spark plug boot, press it down firmly – reassemble the other parts.

• Set the on/off switch to I, the starting position.

• Set the choke lever to OPEN position – even if engine is cold.

• Now start the engine.

Stopping The Engine

Release the throttle trigger (B, Fig. 35) and let the engine return to idle. To stop the engine, move the on/off switch (A) to the “STOP” position. Do not put the stick edger on the ground when the cutting attachment is still moving. In the event that the “STOP” position of the switch will not function, pull the choke lever in the CLOSE position (Fig. 33,page

19) to stop the engine.

Pre-operation checking

WARNING: THE CUTTING ATTACHMENT SHOULD NEVER TURN AT IDLE.Turn the idle speed screw “T” counter-clockwise to reduce the idle RPM, or contact a Servicing Dealer for adjustment and discontinue use until the repair is made. Serious personal injury may result from the cutting attachment turning at idle.

A damaged clutch may cause a cutting attachment to rotate at idle speed and increase the risk of personal injury from loss of control and from contact with the cutting tool.

Working Techniques

General working instructions

WARNING: If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop. Avoid all usage which you consider to be beyond your capability.

Basic safety rules

1. Look around you:

• To ensure that people, animals or other things cannot affect

your control of the machine.

• To ensure that people, animals, etc., do not come into contact

with the cutting attachment or loose objects that are thrown out by the cutting attachment.

WARNING: Do not use the machine unless you are able to call for help in the event of an accident.

OPERATION

2. Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, etc.

3. Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

4. Switch off the engine before moving to another area.

5. Never put the machine down with the engine running.

• Always use the correct equipment.

• Make sure the equipment is well adjusted.

• Follow the safety precautions.

• Organise your work carefully.

• Always use full throttle when starting to cut with the blade.

• Always use sharp blades.

• Avoid stones.

6. Stop working if someone approaches.

WARNING: Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating, as this can result in serious injury. Stop the engine and cutting equipment before you remove material that has wound around the blade shaft as otherwise there is a risk of injury.The bevel gear can get hot during use and may remain so for a while afterwards.You could get burnt if you touch it.

WARNING: Watch out for thrown objects. Always wear approved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 50 ft (15 m). Stop the machine immediately if anyone approaches. Never swing the machine around without first checking behind you to make sure no-one is within the safety zone.

WARNING: Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.

Check before starting

• Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. Discard a blade if cracks are found (Fig. 36).

• Check that the support flange is not cracked due to fatigue or due to being tightened too much. Discard the support flange if it is cracked (Fig. 37).

• Ensure the locking nut has not lost its captive force. The tightening torque of the locking screw should be 11-15 ftlb (15- 20 Nm) (Fig. 37).

• Check that the blade guard is not damaged or cracked.Replace the blade guard if it is cracked (Fig. 38).

WARNING: Never use the machine without a guard or with a defective guard.

WARNING:The complete clutch cover and shaft must be fitted before the machine is started, otherwise the clutch can come loose and cause personal injury. Ensure the cutting attachment cannot come into contact with any object. Make sure no unauthorised persons are in the working area, otherwise there is a risk of serious personal injury.The safety distance is 50 ft (15 metres).

Working methods (Fig. 39)

WARNING:

• Always wear eye protection such as safety goggles.

• Never lean over the rotating cutting head. Rocks or other debris could be thrown into eyes and face and cause serious personal injury.

• Keep the blade guard (A, Fig.40) and the mad guard (B) attached in place at all times when the unit is operated.

• Before starting a job, check the area and remove all obstacles and objects that could be thrown by the blade.

• Do not adjust the wheel height or try to remove anything entangled to the blade with the engine running.

• Before starting the engine, adjust the wheel height for desired cutting depth (Fig.41).

• Before starting a job, plan your direction of travel so that you can always hold the edger on you right side and can walk on a hard surface as much as possible.

• When starting to edge, maintain the engine speed at the level required to perform edging work, and slowly have the blade cut into the edge groove.

• Before edging, make sure the area is soft enough so the blade does not bog down.

• Do not move the edger into the work so fast that the engine or blade bogs down.

• Do not operate using starting throttle lock. It may cause unit uncontrolled, and clutch failure.

• Use care in directing discharge to avoid bystanders, vehicles, glass, and the like.

• When the blade guard is clogged or blade stuck, stop the engine and clean it.

MAINTENANCE

Carburetor Adjustment

Before adjusting the carburetor, clean the cover vents as shown Fig. 47, and air filter as shown Fig. 48, refer to Operation-Starting Unit and Maintenance-Air Filter Sections for details. Allow the engine to warm up prior to carburetor adjustment. This engine is designed and manufactured in order to comply with EPA (Environmental Protection Agency) Phase 1 regulations. The carburetor is factory set and should not require adjusting. The carburetor will permit only adjustment of the “T” screw (Fig. 49).

WARNING: Don’t modify the carburetor in any way in such case the engine will not run in compliance with emissions regulations.

Idle Speed Adjustment

• If the engine starts, runs, and accelerates but will not idle; turn

the idle speed screw “T” clockwise to increase idle speed (Fig.

49).

• If the cutting attachment turns at idle, turn the idle speed screw

“T” counter-clockwise to reduce the idle RPM and stop the cutting attachment movement. If the cutting attachment still moves at idle speed, contact a Servicing Dealer for adjustment and discontinue use until the repair is made.

Fuel Filter

Check the fuel filter (Fig. 50) periodically. Replace it if contaminated or damaged.

Air Filter

WARNING: Do not clean filter in gasoline or other flammable solvent to avoid creating a fire hazard or producing harmful evaporative emissions.

If a power drop is noticed, check the air filter. Open the air filter cover and check the air filter (C, Fig. 51) each day, change the filter if not clean or damaged. Reinstall the air filter into cover. Place the air filter cover onto the stick edger. Tighten the air filter cover screw securely. A used air filter can never be completely cleaned. It is advisable to replace your air filter with a new one after six month of operation. Make sure the cover and the support are clean before fitting the new filter.

CAUTION: Never run the engine without the air filter, serious damage could result. Make sure the air filter is correctly placed in the air filter cover before reassembly. Always replace damaged filters. Do not clean a filter with a brush.

Starter Unit

WARNING: The coil spring is under tension and could fly apart causing serious injuries. Never try to disassemble or modify it.

MAINTENANCE

Engine

Clean the cylinder fins with compressed air or a brush periodically (Fig. 52). Dangerous overheating of engine may occur due to impurities on the cylinder.

WARNING: Never run the machine without all the parts, including the starting housing, securely in place. Because parts can fracture and pose a danger of thrown objects, leave repairs to the flywheel and clutch to trained Servicing Dealers.

Spark Plug

This engine uses a Champion RCJ-6Y with .02” (0.5 mm) electrode gap (Fig. 53). Use an exact replacement and replace every six months or more frequently, if necessary.

WARNING: Never test the ignition system with ignition wire connector removed from spark plug or with unseated spark plug, since uncontained sparking may cause a fire. A loose connection between spark plug terminal and ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.

Use only resistor type spark plugs of the approved range. Factors such as:

- too much oil in fuel mix;

- dirty air filter;

- unfavourable running conditions, e.g. operating at part load; may result in rapid deterioration of the spark plug.

Muffler

WARNING: Do not operate your stick edger if the muffler is damaged, missing or modified. An improperly maintained muffler will increase the risk of fire and hearing loss.

Bevel Gear

The reduction gears are lubricated by multipurpose, molybdenum bisulphide grease in the bevel gear. At every 25 hours of use, supply the bevel gear with new grease (Fig.54). Remove the cutter holders (2)-(4) before installing new grease to arrange for old grease to exit (Fig.55).

CAUTION - When removing and installing the holder (4), use care not to allow any dirt and dust entering in to the gear case (Fig.55).

CAUTION: do not use a grease gun. The high pressure can damage the bearings and seals.

Use high quality molybdenum bisulphide grease.
