The blade should be angled forward a little. 2)Grass clearing The suspension hook should hang approximately 20 cm under the hip so that the blade is parallel to the ground. Correct balance 1)Forestry clearing Move the suspension eye forwards or backwards. If the blade is balanced a 1020 cm above the ground it is easier to avoid stones. 2)Grass and brush cutting. Let the blade balance at a comfortable clearing height, i.e. close to the ground. Basic clearing techniques • Always carry out clearing and trimming at full throttle. • Always drop to idling speed after each working operation. Longer periods running at full throttle without loading the engine (that is without resistance, which the engine feels from the cutting equipment when trimming) can lead to serious engine damage. Designations • Forestry clearing is a general term for cutting small trees where each stem is cut individually. A saw blade is used. • Brush cutting is a general term for clearing grass. Grass blades are used for this purpose. • Grass trimming is a general term for light clearing, e.g. around edges or around trees. A trimmer head or plastic blade is used. ! ! WARNING! Sometimes branches, grass or wood can get caught between the guard and cutting equipment. Always stop the engine when cleaning. English – 11 SAFETY INSTRUCTIONS Clearing‘s ABC A. Always use the correct equipment. B. Always have well adjusted equipment. C. Follow the safety instructions. D. Organise the work well. E. Always use full throttle when applying the blade. F. Always use a sharp blade. G. Avoid stones. H. Guide the direction of fall (use the wind). ! ! WARNING! Avoid cutting in the cutting region between 12 and 3 o‘clock on the blade. Kickback can occur due to the blade‘s rotation speed in this area of the blade when applied on thick stems. Working methods • Before you start clearing, check the clearing area, its condition, slopes, if there are stones, pits, etc. • Thereafter start at the end which is easiest, and make a good start to the clearing. • Work systematically to and from and across the area. Each stroke should encompass a working area of 4-5 metres. This then utilises the full working area of the machine in both directions and provides the operator with an easy and variable working area to work through. • The length of the pathway should be approx. 75 m. Move the fuelling station as work progresses. • On sloping ground the pathway should run parallel to the slope. It is far easier to work along a slope then up and down a slope. • The pathway should be planned so that you avoid going over ditches or other obstacles. Also adapt the pathway to the wind conditions so that the cleared stems fall on the part of the stand that has been cleared. Forestry clearing using a saw blade • When applying the blade to heavier stems the risk of kickback increases. You should therefore avoid applying the blade on the cutting area between 12 and 3 o‘clock. • To fell to the left, the lower section of the tree should carry to the right. Angle the blade and move it with a resolute movement diagonally down to the right. At the same time press against the stem using the blade guard. Apply the blade on the area between 3-5 o‘clock. Use full throttle when applying the blade. • To fell to the right, the lower section of the tree should carry to the left. Angle the blade and move it with a resolute movement diagonally up to the left. Apply the blade on the area between 3 and 5 o‘clock so that the blade‘s direction of rotation carries the lower section of the tree to the left. • To fell a tree forwards the lower section of the tree should be drawn backwards. Draw the blade backwards with a quick and resolute movement. 12 – English 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. • If the blade should jam in the stem, never jerk the machine free. If you do this the blade, angle gear, shaft or the handlebars can be damaged. Release the handlebars and grip the shaft with both hands and slowly pull the machine free. Brush cutting using the saw blade • Thin stems and brush are mown down. Work by swinging the machine sideways. • Try to cut several stems in one movement. • With groups of hardwood stems, first clear around the group. Cut high on the stems around the outside of the group to avoid jamming. Now cut the stumps to the required height. Now try to come in with the blade and cut from the centre of the group. If it is still difficult to gain access, cut long stumps and let the stems fall down. This will reduce the risk of jamming. Brush cutting using a grass blade • A blade is used for all types of h...
