English? 3 INTRODUCTION Dear Customer, Thank you for choosing a McCulloch product. You are thereby part of a story that started long ago, when the McCulloch Corporation started its manufacturing of engines during World War II. In 1949, when McCulloch introduced its?rst light one-man chainsaw, woodworking would never be the same again. The line of innovative chainsaws would continue over the decades, and business was expanded,?rst by airplane and kart engines in the 1950s, then by mini chainsaws in the 1960s. Later, in the 1970s and 80s, trimmers and blower vacs were added to the range. Today, as a part of the Husqvarna group, McCulloch continues the tradition of powerful engines, technical innovations, and strong designs that have been our hallmarks for more than half a century. Lowering fuel consumption, emissions and noise levels are of top priority to us, as is improving safety and userfriendliness. We certainly hope that you will be satis?ed with your McCulloch product, as it is designed to be your companion for a long time. By following this operators manual?s advice on usage, service, and maintenance, its lifespan can be extended. If you should need professional help with repair or service, please use the Service Locator at McCulloch has a policy of continuous product development and therefore reserves the right to modify the design and appearance of products without prior notice.

Release the throttle trigger and check that the blades stop and remain stationary. If the blades move when the throttle trigger is in the idle position then the carburettor idle setting must be adjusted. See instructions under the heading Maintenance. English? 7 GENERAL SAFETY PRECAUTIONS Stop switch Use the stop switch to switch off the engine. Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached.! Start the engine and make sure the engine stops when you move the stop switch to the stop setting. The stop switch automatically returns to the start position. In order to prevent uge or fumes coming into contact with sparks or naked?ames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers. When storing and transporting fuel always use approved containers intended for this purpose. When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to?nd out where to dispose of excess fuel. Ensure the machine is cleaned and that a complete service is carried out before long-term storage. The transport guard must always be?tted to the cutting attachment when the machine is being transported or in storage. Secure the machine during transport.??? The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 socalled knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage. When working at continuous high revs a higher octane rating is recommended.? Two-stroke oil? For best results and performance use Universal, Universal powered by McCULLOCH two-stroke engine oil, which is specially formulated for our aircooled two-stroke engines. Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). Never use oil intended for four-stroke engines. A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters. Mixing ratio 1:50 (2%) with Universal, Universal powered by McCULLOCH two-stroke oil. 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines. Petrol, litre Two-stroke oil, litre 2% (1:50) 0,10 0,20 0,30 0,40 3% (1:33) 0,15 0,30 0,45 0,60????! Fuel WARNING! Take care when handling fuel. Bear in mind the risk of?re, explosion and inhaling fumes.??? CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.! WARNING! Fuel and fuel fumes are highly in?ammable and 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. 10? English FUEL HANDLING Mixing?? Always mix the petrol and oil in a clean container intended for fuel. Always start by?lling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol. Mix (shake) the fuel mixture thoroughly before?lling the machine?s fuel tank. Fueling! WARNING! Taking the following precautions, will lessen the risk of?re: Do not smoke or place hot objects near fuel. Always shut off the engine before refuelling. Refuel in a well ventilated area. Never fuel the machine indoors. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. Tighten the fuel cap carefully after refuelling. Always move the machine away from the refuelling area and source before starting.??? Do not mix more than one month?s supply of fuel at a time. If the machine is not used for some time the fuel tank should be emptied and cleaned.! WARNING! The catalytic converter muf?er gets very hot during and after use. This also applies during idling. Be aware of the?re hazard, especially when working near?ammable substances and/ or vapours.??? Always use a fuel container with an anti-spill valve. Clean the area around the fuel cap. Contamination in the tank can cause operating problems. Ensure that the fuel is well mixed by shaking the container before?lling the tank. MC CULLOCH SUPERLITE 4528

Never allow children to use the machine. Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment. Ensure that no-one comes closer than 15 m while you are working. Never allow anyone else to use the machine without?rst ensuring that they have understood the contents of the operator?s manual. Never work from a ladder, stool or any other raised position that is not fully secured.? Make sure that your hands and feet do not come near the cutting attachment when the engine is running.???? When the engine is switched off, keep your hands and feet away from the cutting attachment until it has stopped completely. Watch out for stumps of branches that can be thrown out during cutting. Do not cut too close to the ground. Stones and other objects can be thrown out. Check the working area for foreign objects such as electricity cables, insects and animals, etc, or other objects that could damage the cutting attachment, such as metal items. If any foreign object is hit or if vibrations occur stop the machine immediately. Disconnect the HT lead from the spark plug. Check that the machine is not damaged. Repair any damage.????? Keep in mind that the operator is responsible for accidents or hazards occuring to other people or their property. 14? English WORKING TECHNIQUES? If anything jams in the blades while you are working, switch off the engine and wait until it has stopped completely before cleaning the blades. Disconnect the HT lead from the spark plug. If the blades get stuck, they can be loosened by sticking the combination spanner into the gear housing. Remove the lubricant plug and stick the combination spanner into the gearing and turn it back and forth.? Hold the machine as close to your body as possible to get the best balance. Safety instructions after completing work?? Make sure that the tip does not touch the ground. Do not rush the work, but work steadily until all the branches have been cut back cleanly. ERGOLITE 6028?? The transport guard should always be?tted to the cutting attachment when the machine is not in use. Make sure the cutting attachment has stopped before cleaning, carrying out repairs or an inspection. Disconnect the HT lead from the spark plug. Always wear heavy-duty gloves when repairing the cutting attachment. This is extremely sharp and can easily cause cuts. The hedge trimmer?s rear handle can be set in?ve positions by pulling out the catch. See?gure. When the handle is adjusted, the hedge trimmer must be idling or not running.??? Store the machine out of reach of children. Use only original spare parts for repairs.? While working the handle should always be facing upwards irrespective of how the hedge trimmer is directed. Basic working techniques??? Work with a swinging action from the bottom upwards when trimming sides. Adjust the throttle setting to suit the load. When trimming a hedge the engine should always face away from the hedge. English? 15 MAINTENANCE Carburettor Adjustment of the idle speed Before any adjustments are made, make sure that the air?lter is clean and the air?lter cover is?tted. MC CULLOCH SUPERLITE 4528

9 Make sure the start throttle position is disengaged. Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the T screw clockwise until the cutting attachment starts to move. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine runs smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to move. Rec. idle speed: See the Technical data section. is incorrectly adjusted or that too much oil has been mixed with the petrol. On muf?ers?tted with a catalytic converter, the mesh must be checked, and if necessary cleaned, monthly. If the mesh is damaged it must be replaced. If the mesh is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the muf?er. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston. CAUTION! Never use a machine with a defective muf?er.! WARNING! Muf?ers?tted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of?re! Cooling system! Muf?er WARNING! If the idle speed cannot be adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired. To keep the working temperature as low as possible the machine is equipped with a cooling system. The cooling system consists of: CAUTION! Some muf?ers are?tted with a catalytic converter. See chapter on Technical data to see whether your machine is?tted with a catalytic converter. The muf?er is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause?re if directed against dry and combustible material Cooling?ns on the cylinder. Cylinder cover (directs cold air over the cylinder). Air intake through the crankcase (inside the tank). Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder. Spark plug The spark plug condition is in?uenced by:? Some muf?ers are equipped with a special spark arrestor mesh. If your machine has this type of muf?er, the mesh must be cleaned. This is best done with a wire brush. On muf?ers without a catalytic converter, the mesh should be cleaned or replaced if necessary once a week. If the mesh is damaged it must be replaced. If the mesh is frequently blocked, this can be a sign that the carburettor 16? English?? Incorrect carburettor adjustment. An incorrect fuel mixture (too much or incorrect type of oil). A dirty air?lter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting dif?culties. MAINTENANCE If the machine is low on power, dif?cult to start or runs poorly at idle speed: always check the spark plug?rst before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0,5 mm. The spark plug should be replaced after about a month in operation or earlier if necessary. Oiling the air?lter Always use?lter oil, art. no The?lter oil contains a solvent to make it spread evenly through the?lter. You should therefore avoid skin contact. Put the?lter in a plastic bag and pour the?lter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the?lter inside the plastic bag and pour off the excess before?tting the?lter to the machine. Never use common engine oil. This would drain through the?lter quite quickly and collect in the bottom. CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/ cylinder. Check that the spark plug is?tted with a suppressor. Air?lter Gear The air?lter must be regularly cleaned to remove dust and dirt in order to avoid:????? Carburettor malfunctions Starting problems Loss of engine power Unnecessary wear to engine parts. Excessive fuel consumption. There is a plug for?lling lubricant on the gear housing. Use the grease tube to?ll with grease and repeat every 25 hours. Use Husqvarna?s special grease. Clean the?lter every 25 hours, or more regularly if conditions are exceptionally dusty. Cleaning the air?lter Remove the air?lter cover and take out the?lter. Wash it clean in warm, soapy water. Allow the?lter to dry and then oil it in according to the instructions. An air?lter that has been in use for a long time cannot be cleaned completely. The?lter must therefore be replaced with a new one at regular intervals. A damaged air?lter must always be replaced. CAUTION! The gear housing must not be?lled completely with grease. The grease expands as the machine heats up during operation. If the gear housing was completely?lled with grease it could damage the seals and lead to leakage of grease. The grease in the bevel gear does not normally need to be changed except if repairs are carried out. Cutting unit Check that the cutting units' screws are?tted correctly. Tighten them with a tightening torque of 7-10 Nm. English? 17 MAINTENANCE Cleaning and lubrication Clean any resin and plant residue from the blades using cleaning agent (UL22) before and after using the machine. Check that the blade edges are not damaged or deformed. File away any burrs. Check that the blades move freely. Remove the lubrication plug in the gear housing and stick in the combination spanner and turn back and forth. Lubricate the blade bars with special grease, part no (UL 21) before long periods of storage. 18? English MAINTENANCE Maintenance schedule The following is a list of the maintenance that must be performed on the machine. Most of the items are described in the Maintenance section. The user must only carry out the maintenance and service work described in this Operator?s Manual. More extensive work must be carried out by an authorized service workshop. Maintenance Clean the outside of the machine. Make sure the throttle trigger lock and the throttle function correctly from a safety point of view. In order to reduce the risk of?re, dirt, leaves and surplus lubricant, etc must be cleaned from the muf?er, exhaust pipe and engine. Check that the stop switch works correctly. Check that the blades do not move when the engine is idling. Check that the blades are undamaged and show no signs of cracking or other damage. Replace the blades if necessary. Check that the blade guard is not damaged or distorted. Replace the blade if the blade guard is bent or damaged. Replace the cutting unit if it is bent or damaged. Check that the hand guard is not damaged. Replace the guard if damaged. Check that nuts and screws are tight. Check that there are no fuel leaks from the engine, tank or fuel lines.
