SAFETY INSTRUCTIONS Adjusting the harness and clearing saw ! WARNING! When working with the clearing saw it should always be hooked in the harness. If this is not done, you cannot control the clearing saw safely and this can result in injury to yourself or someone else. Never use a harness with a defective quick release catch. Quick release On the front is an easily accessible, quick release catch. This is activated by pulling the outer part of the chest plate straight out.
SAFETY INSTRUCTIONS Clearing‘s ABC A. B. C. D. E. F. G. H. Always use the correct equipment. Always have well adjusted equipment. Follow the safety instructions. Organise the work well. Always use full throttle when applying the blade. Always use a sharp blade. Avoid stones. Guide the direction of fall (use the wind). ! WARNING! Avoid cutting in the cutting region between 12 and 3 o‘clock on the blade.
SAFETY INSTRUCTIONS • Large stems must be cut from two sides. Determine in which direction the stem should fall. First apply the saw to the felling side. Then cut from the other side to fell the stem. The feed pressure should be applied with regard to the size of the stem‘s hardness. Small stems require more pressure, while large stems require less pressure. • If the stems are tightly packed adapt the through-speed with this in mind.
SAFETY INSTRUCTIONS Grass trimming using the trimmer head • Hold the trimmer head just above the ground at an angle. It is the end of the cord that carries out the work. Let the cord work at its own pace. Do not press the cord into the area to be cut. • The cord can easily remove grass and weeds up against walls, fences, trees and borders, however, it can also damage sensitive bark on trees and bushes and damage fence posts.

FUEL HANDLING Fuel mixture Mixture NOTE! The machine is fitted with a two-stroke engine and must always be run on a mixture of petrol and two-stroke oil. It is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel. • Always mix gasoline and oil in a clean container intended for fuel.
START AND STOP Control before starting For reasons of safety follow these recommendations! • 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. • Check that the support flange is not cracked due to fatigue or due to being tightened too much.
MAINTENANCE Carburettor Basic setting Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After your unit has been run 8-10 tanks of fuel the engine has broken in.
