If you do not understand the safety rules, do not attempt to fuel your unit. Contact an authorized service dealer. STARTING A COLD ENGINE (or a warm engine after running out of fuel) Starting position FUELING ENGINE WARNING: Remove fuel cap slowly when refueling. This engine is certified to operate on unleaded petrol. Before operation, petrol must be mixed with a good quality 2-cycle air-cooled engine oil. We recommend McCulloch brand oil mixed at a ratio of 40:1 (2.5%). A 40:1 ratio is obtained by mixing 5 liters of unleaded petrol with 0,125 liter of oil. DO NOT USE automotive oil or boat oil. These oils will cause engine damage. When mixing fuel, follow instructions printed on oil container. Once oil is added to petrol, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit. IMPORTANT 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. To avoid engine problems, empty the fuel system before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. HOW TO STOP YOUR UNIT S To stop the engine, move the ON/STOP (I/0) switch to the STOP (0) position. ON/STOP (I/0) switch Throttle lock--out HOW TO START YOUR UNIT WARNING: Avoid any contact with the muffler. A hot muffler can cause serious burns. Primer Bulb Starter Handle Start Lever Muffler NOTE: The throttle lock--out is designed to prevent unintentional use of the throttle trigger. The lock--out must be pressed with the palm of your hand as you grip the throttle handle before the trigger can be used. DO NOT squeeze the throttle trigger until the engine has started and runs. 1. Set unit on a flat surface. 2. Move ON/STOP (I/0) switch to the ON (I) position. 3. Slowly press the primer bulb 6 times. 4. Move the start lever to the START position. 5. Pull starter rope handle sharply until engine starts and runs. 6. Allow unit to run for 10--15 seconds, then fully squeeze the throttle trigger to disengage the starting system. STARTING A WARM ENGINE 1. Move ON/STOP (I/0) switch to the ON (I) position. 2. Pull starter rope sharply until engine starts and runs. NOTE: Normally, the warm starting procedure can be used within 5 -- 10 minutes after the unit is turned off. If the unit sits for more than 10 minutes without being run, it will be necessary to start the unit by following the steps under STARTING A COLD ENGINE or following the starting instruction steps shown on the unit. STARTING A FLOODED ENGINE Move the start lever to the RUN position and fully squeeze throttle trigger. Pull the starter handle repeatedly while squeezing throttle trigger until engine starts and runs. This could require pulling the starter handle many times, depending on how badly the unit is flooded.If the unit still doesn’t start, refer to TROUBLESHOOTING TABLE. 9 OPERATING POSITION ALWAYS WEAR: Hearing protection Safety helmet Eye protection Heavy, long pants Boots Cut from your left to your right. When operating unit, clip shoulder harness onto clamp, stand as shown and check for the following: S Wear eye protection and heavy clothing. S Extend your left arm and hold handlebar grip with your left hand. S Hold throttle grip with your right hand with finger on throttle trigger. S Keep unit below waist level. S Maintain full weight of tool on both shoulders. S Without bending over, keep the blade or trimmer head near and parallel to the ground and not crowded into material being cut. OPERATING INSTRUCTIONS FOR USE WITH TRIMMER HEAD WARNING: Always wear eye protection. Never lean over the trimmer head. Rocks or debris can ricochet or be thrown into eyes and face and cause blindness or other serious injury. Before trimming, bring engine to a speed sufficient to cut material to be trimmed. Do not run the engine at a higher speed than necessary. The cutting line will cut efficiently when the engine is run at less than full throttle. At lower speeds, there is less engine noise and vibration. The cutting line will last longer and will be less likely to “weld” onto the spool. Always release the throttle trigger and allow the engine to return to idle speed when not cutting. To stop engine: S Release the throttle trigger. S Move ON/STOP (I/0) switch to the STOP (0) position. TRIMMER LINE ADVANCE Advance line by tapping the bottom of the cutting head lightly on the ground while engine is running at full speed. The metal line limiter blade attached to the guard will cut the line to the proper length. WARNING: Use only 2,4 mm diameter line. Other sizes of line will not advance properly and can cause serious injury. Do not use other materials such as wire, string, rope, etc. Wire can break off during cutting and become a dangerous missile that can cause serious injury. CUTTING METHODS WARNING: Use minimum speed and do not crowd the line when cutting around hard objects (rock, gravel, fence posts, etc.), which can damage the trimmer head, become entangled in the line, or be thrown causing a serious hazard. S The tip of the line does the cutting. You will achieve the best performance and minimum line wear by not crowding the line into the cutting area. The right and wrong ways are shown below. Tip of line does the cutting. Right Line crowded into work area. Wrong S The line will easily remove grass and weeds from around walls, fences, trees and flower beds, but it also can cut the tender bark of trees or shrubs and scar fences. S For trimming or scalping, use less than full throttle to increase line life and decrease head wear, especially: S During light duty cutting. S Near objects around which the line can wrap such as small posts, trees or fence wire. S For mowing or sweeping, use full throttle for a good clean job. TRIMMING -- Hold the bottom of the trimmer head about 8 cm above the ground and at an angle. Allow only the tip of the line to make contact. Do not force trimmer line into work area. Trimming 8 cm above ground SCALPING -- The scalping technique removes unwanted vegetation down to the ground. Hold the bottom of the trimmer head about 8 cm above the ground and at an angle. Allow the tip of the line to strike the ground around trees, posts, monuments, etc. This technique increases line wear. 10 Scalping MOWING -- Your trimmer is ideal for mowing in places conventional lawn mowers cannot reach. In the mowing position, keep the line parallel to the ground. Avoid pressing the head into the ground as this can scalp the ground and damage the tool. Mowing SWEEPING -- The fanning action of the rotating line can be used to blow away loose debris from an area. Keep the line parallel to and above the area surface and swing the tool from side to side. Sweeping OPERATING INSTRUCTIONS FOR USE WITH WEED BLADE S Blade Thrust is a reaction that only occurs when using a bladed unit. This reaction can cause serious injury such as amputation. Carefully study this section. It is important that you understand what causes blade thrust, how you can reduce the chance of its occurring, and how you can remain in control of unit if blade thrust occurs. S WHAT CAUSES BLADE THRUST -- Blade Thrust can occur when the spinning blade contacts an object that it does not cut. This contact causes the blade to stop for an instant and then suddenly move or “thrust” away from the object that was hit. The “thrusting” reaction can be violent enough to cause the operator to be propelled in any direction and lose control of the unit. The uncontrolled unit can cause serious injury if the blade contacts the operator or others. S WHEN BLADE THRUST OCCURS -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. By using the unit properly, the occurrence of blade thrust will be reduced and the operator will be less likely to lose control. S Cut only grass, weeds, and woody brush up to 1 cm in diameter with the weed blade. Do not let the blade contact material it cannot cut such as stumps, rocks, fences, metal, etc., or clusters of hard, woody brush having a diameter greater than 1 cm. S Keep the blade sharp. A dull blade is more likely to snag and thrust. S Cut only at full throttle. The blade will have maximum cutting power and is less likely to bind or stall. S “Feed” the blade deliberately and not too rapidly. The blade can thrust away if it is fed too rapidly. S Cut only from your left to your right. Cutting on right side of the shield will throw debris away from the operator. S Use the shoulder harness and keep a firm grip on the unit with both hands. A properly adjusted shoulder harness will support the weight of the unit, freeing your arms and hands to control and guide the cutting motion. S Keep feet comfortably spread apart and braced for a possible sudden, rapid thrust of unit. Do not overreach. Keep firm footing and balance. S Keep blade below waist level; it will be easier to maintain control of unit. S Do not raise the engine above your waist as the blade can come dangerously close to your body. S Do not swing unit with such force that you are in danger of losing your balance. Bring the engine to cutting speed before entering the material to be cut. If the blade does not turn when you squeeze the throttle trigger, make sure shaft is fully inserted into the engine. Always release the throttle trigger and allow engine to return to idle speed when not cutting. The blade should not turn while the engine is running at idle. If the blade turns at idle, do not use your unit. Refer to the CARBURETOR ADJUSTMENT section or contact your authorized service dealer. S Maintain good firm footing while using the unit. Do this by planting feet firmly in a comfortable apart position. S Cut while swinging the upper part of your body from left to right. 11 S As you move forward to the next area to cut, be sure to maintain your balance and footing. RECOMMENDED CUTTING POSITION 2 o’clock Cut using the 2 o’clock to 4 o’clock position of the blade WARNING: The operator or others must not try to clear away cut material with the engine running or the blade turning to avoid serious injury. Stop engine and blade before removing materials wrapped around blade or shaft. 4 o’clock MAINTENANCE The life span of the machine can be reduced and the risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information, please contact your nearest authorised service dealer. WARNING: Disconnect the spark plug before performing maintenance except for carburetor adjustments.
