Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc. 4 Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground. 5 Take great care when cutting a tree that is under tension. A tree that is under tension may spring back to its normal position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury. 6 Keep a good balance and a firm foothold. Do not overreach. Keep proper footing and balance at all times. 7 Always hold the machine with both hands. Hold the machine on the right side of your body. Keep all parts of your body away from the hot surfaces. Keep all parts of your body away from the rotating cutting attachment. 8 Keep the cutting attachment below waist level. 9 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance. 10 Never put the machine down with the engine running unless you have it in clear sight. The ABC of clearing • Always use the correct equipment. • Make sure the equipment is well adjusted. • Follow the safety precautions. • Organise your work carefully. • Always use full throttle when starting to cut with the blade. • Always use sharp blades. • Avoid stones. • Control the felling direction (take advantage of the wind). 22 – English WORKING TECHNIQUES ! WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating, as this can result in serious injury. Stop the engine and cutting equipment before you remove material that has wound around the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards.You could get burnt if you touch it. ! WARNING! Watch out for thrown objects. Always wear approved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. Stop the machine immediately if anyone approaches. Never swing the machine around without first checking behind you to make sure no-one is within the safety zone. ! WARNING! Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning. Working methods WARNING! Machines fitted with saw ! blades or grass blades can be thrown violently to the side when the blade comes into contact with a fixed object. This is called blade thrust. A blade thrust can be violent enough to cause the machine and/ or operator to be propelled in any direction, and possibly lose control of the machine. Blade thrust can occur without warning if the machine snags, stalls or binds. Blade thrust is more likely to occur in areas where it is difficult to see the material being cut. Avoid cutting with the area of the blade between the 12 o’clock and 3 o’clock positions. Because of the speed of rotation of the blade, blade thrust can occur if you attempt to cut thick stems with this area of the blade. • Start at whichever end of the area is easiest, and clear an open space from which to work. • Work systematically to and fro across the area, clearing a width of around 4-5 m on each pass. This exploits the full reach of the machine in both directions and gives the operator a convenient and varied working area to work in. • Clear a strip around 75 m long. Move your fuel can as work progresses. • On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it. • You should plan the strip so that you avoid going over ditches or other obstacles on the ground. You should also orient the strip to take advantage of wind conditions, so that cleared stems fall in the cleared area of the stand. • Before you start clearing, check the clearing area, the type of terrain, the slope of the ground, whether there are stones, hollows etc. English – 23 WORKING TECHNIQUES Forestry clearing using a saw blade • The risk of blade thrust increases with increasing stem size.You should therefore avoid cutting with the area of the blade between 12 o’clock and 3 o’clock. • To fell to the left, the bottom of the tree should be pushed to the right. Tilt the blade and bring it diagonally down to the right, exerting firm pressure. At the same time push the stem using the blade guard. Cut with the area of the blade between 3 o’clock and 5 o’clock. Apply full throttle before advancing the blade. •To fell to the right, the bottom of the tree should...
