SAFETY INSTRUCTIONS Personal protective equipment IMPORTANT! You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment. ! WARNING! Listen out for warning signals or shouts when you are wearing hearing protection. Always remove your hearing protection as soon as the engine stops.
SAFETY INSTRUCTIONS Cutting attachment guard Quick release This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment. There is an easily accessible, quick release fitted at the front as a safety precaution in case the engine catches fire, or in any other situation that requires you to free yourself from the machine and harness.
SAFETY INSTRUCTIONS ! WARNING! Bear in mind that: Engine exhaust fumes contain carbon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated. Checking, maintaining and servicing the machine′s safety equipment IMPORTANT! All servicing and repair work on the machine requires special training. This is especially true of the machine′s safety equipment.
SAFETY INSTRUCTIONS • See instructions under the heading Start. Start the machine and apply full throttle. Release the throttle and check that the cutting attachment stops and remains at a standstill. If the cutting attachment rotates with the throttle in the idle position then the carburettor idle setting must be checked. See instructions under the heading Maintenance. • Check that the vibration damping element is undamaged and securely attached.
SAFETY INSTRUCTIONS 2 3 Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended file gauge. An incorrectly sharpened or damaged blade increases the risk of accidents. • Tighten the nut using the socket spanner. 35-50 Nm (3.55 kpm). CAUTION! The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.
SAFETY INSTRUCTIONS • • Make sure that the blade is well supported when you file it. Use a 5.5 mm round file with a file holder. The filing angle is 15°. File alternate teeth to the right and those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a flat file, in exceptional cases. If so, this should be done before filing with a round file. The top edges must be filed down by the same amount for all the teeth.
SAFETY INSTRUCTIONS General safety precautions • IMPORTANT! The machine is only designed for trimming grass, grass clearing and/or forestry clearing. Place the machine on the ground, ensure the cutting attachment is clear of twigs and stones. Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot). Then grip the starter handle with your right hand and pull the starter cord.
SAFETY INSTRUCTIONS • The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage. ! WARNING! Take care when handling fuel. Bear in mind the risk of fire, explosion and inhaling fumes. General working instructions IMPORTANT! This section describes the basic safety precautions for working with clearing saws and trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert.
SAFETY INSTRUCTIONS Correct balance ! Let the cutting attachment rest lightly on the ground. If you use a saw blade it should balance about 10 cm above the ground to prevent contact with stones and the like. Adjust the position of the support hook to balance the clearing saw correctly. WARNING! Avoid cutting with the area of the blade between the 12 o’clock and 3 o’clock positions.
SAFETY INSTRUCTIONS Grass clearing using a grass blade ! • Grass blades and grass cutters must not be used on woody stems. • A grass blade is used for all types of tall or coarse grass. • The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-to-right is the return stroke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting. WARNING! Watch out for thrown objects.
SAFETY INSTRUCTIONS Cutting • The trimmer is ideal for cutting grass that is difficult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool. • Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.

Fit the adapter (I) and bracket (J) with the two screws (K) as shown. Fit the blade guard (A) to the adapter using the 4 screws (L) as shown. CAUTION! Use the recommended blade guard. See the Technical data section. Hook the blade guard/combination guard (A) onto the fitting on the shaft and secure with the bolt.
ASSEMBLY arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut. Fitting a trimmer guard and Superauto II 1" trimmer head • Fit the bottom half of the trimmer head (K) to the cover (I) by pressing them together, with the cut-outs on the bottom half aligned with the catches on the cover. • To dismantle, follow the instructions in the reverse order.
ASSEMBLY Adjusting the harness and clearing saw ! WARNING! When using a clearing saw it must always be hooked securely to the harness. Otherwise you will be unable to control the clearing saw safely and this can result in injury to yourself or others. Never use a harness with a defective quick release. Correct balance Let the cutting attachment rest lightly on the ground. If you use a saw blade it should balance about 10 cm above the ground to prevent contact with stones and the like.
FUEL HANDLING Fuel When the oil level is low, top up using engine oil to the edge of the oil refill hole. CAUTION! The machine is equipped with a four-stroke engine. Make sure that there is always sufficient oil in the oil tank. ! WARNING! Always ensure there is adequate ventilation when handling fuel. The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours.
STARTING AND STOPPING Check before starting • Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found.
STARTING AND STOPPING Warm engine Starting Ignition: Set the stop switch to the start position. Choke: Put the choke in working position. ! Primer bulb: Press the primer bulb repeatedly until fuel begins to fill the bulb. The bulb need not be completely filled. O I L 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.
MAINTENANCE Carburettor ! 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. The muffler on your machine is equipped with a spark arrestor mesh, this should be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage. Function CAUTION! Never use a machine with a defective muffler. • • The carburettor governs the engine’s speed via the throttle control.
MAINTENANCE If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0,6-0,7 mm. The spark plug should be replaced after about a month in operation or earlier if necessary. 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 fitted with a suppressor.
MAINTENANCE • See the cutting attachment packaging for correct sharpening instructions. • Sharpen blades and cutters using a single-cut flat file. • Sharpen all edges equally to maintain the balance of the blade. ! • Adjust the blade setting. This should be 1 mm. WARNING! Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the specified type.
MAINTENANCE Maintenance schedule Monthly maintenance Below you will find some general maintenance instructions. • Clean the fuel tank. • Clean the outside of the carburettor and the space around it. • Check fuel hose for cracks or other damage. Change if necessary. • Change the fuel filter in fuel tank. • Check electrical wires and connections. • Replace the spark plug. Check that the spark plug is fitted with a suppressor. • Change the air filter.
