16 – English English – 17 7 Take great care when you cut with the top edge of the bar, i.e. when cutting from the underside of the object. This is known as cutting on the push stroke. The chain tries to push the saw back towards the user. Unless the user resists this pushing force there is a risk that the saw will move so far backwards that only the kickback zone of the bar is in contact with the tree. This will cause kickback. Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting on the pull stroke. In this case the saw pulls itself towards the tree and the front edge of the saw provides a natural rest when cutting. Cutting on the pull stroke gives you better control over the saw and the position of the kickback zone. 8 Follow the instructions on sharpening and maintaining your bar and chain. When you replace the bar and chain use only combinations that are recommended by us. See the sections on ”Cutting equipment” and ”Technical data”. The risk of kickback is increased if you use the wrong cutting equipment or a chain that is not sharpened correctly. The wrong combination of bar and chain can increase the risk of kickback! General rules 1 If you understand what kickback is and how it happens then you can reduce or eliminate the element of surprise. By being prepared you reduce the risk. Kickback is usually quite mild, but it can sometimes be very sudden and violent. 2 Always hold the saw firmly with your right hand on the rear handle and your left hand on the front handle. Wrap your fingers and thumb around the handles. You should use this grip whether you are right-handed or lefthanded. This grip minimises the effect of kickback and lets you keep the saw under control. Do not let go of the handles! 3 Most kickback accidents happen during limbing. Make sure you are standing firmly and that there is nothing in the way that might make you trip or lose your balance. Lack of concentration can lead to kickback if the kickback zone of the bar accidentally touches a branch, nearby tree or some other object. 4 Never use the saw above shoulder height and try not to cut with the tip of the bar. Never use the saw onehanded! 5 In order to keep control of your saw, always maintain a firm foothold. Never work on a ladder, in a tree or any other insecure support. 6 Always use a fast cutting speed, i.e. full throttle. SAFETY INSTRUCTIONS SAFETY INSTRUCTIONS GENERAL SAFETY PRECAUTIONS Chain saws are designed solely for cutting wood. The only cutting equipment that can be used with this chain saw are the combinations of bars and chains recommended in the ”Technical data” section. Never use a chain saw if you are tired, if you have drunk alcohol, or if you are taking medication that affects your vision, your judgement or your coordination. 3 Always wear suitable protective clothing. See the section on ”Personal protective equipment”. 4 Never use a chain saw that has been modified in any way from its original specification. Never use a chain saw that is faulty. Carry out the regular checks, maintenance and service routines described in this manual. Some maintenance and service measures must be carried out by trained specialists. See the section on ”Maintenance”. STARTING • Never start a chain saw unless the bar, chain and all covers are fitted correctly. (See the section on ”Assembly”). • Never start a chain saw indoors. Exhaust fumes can be dangerous. • Before starting the saw make sure there are no people or animals nearby who might be put at risk. • The chain brake should be activated when starting (see instructions under the heading Start and stop). Do not drop start. This method is very dangerous because you may lose control of the saw (see instructions under the heading Start and stop). • Place the saw on the ground and hold the rear handle down with your right foot. Grasp the front handle firmly using your left hand. Make sure the chain saw is steady and the chain is not touching the ground. Then grasp the starter handle with your right hand and pull the starter cord. Never wrap the starter cord around your hand. 7 FUEL SAFETY (Refuelling, fuel mixture, storage.) Fuel and fuel vapour are highly inflammable. Take care when handling fuel and chain oil. Keep away from naked flames and do not breathe in fuel vapour. • Never try to refuel the saw while it is running. • Make sure there is plenty of ventilation when refuelling or mixing fuel (2-stroke mixture). • Move the saw at least 3 m from the refuelling point before starting it. • Never start the chainsaw: a) If you have spilt fuel or chain oil on the saw. Wipe off the spill and allow remaining fuel to evaporate. b) If you spill fuel or chain oil on yourself or your clothes. Change your clothes. c) If there is a fuel leak. Check regularly for leaks from the FUEL CAP and FUEL LINES. Min. 3 m (10 ft) • Always store the chain saw and fuel away from any sources of sparks or naked flames, e.g. machines, electric motors, relay...
