Safety Instructions for Use

Before working with the device

  • Before using our device, please read this manual carefully to familiarize yourself with it.
  • Do not work with a chainsaw if you are tired, sick, under stress, take medications that make you feel tired, AL-KOgol or drugs.
  • Chainsaw work should be performed in a well-ventilated work area. Do not turn on or use the device in enclosed spaces or buildings. Exhaust fumes contain hazardous carbon monoxide.
  • Do not use the chain saw in conditions of strong wind, bad weather, poor visibility, very high or very low temperatures.
  • Before each tree is AL-KO, check for dead branches that may fall during operation.
  • Use non-slip safety shoes, tight-fitting clothing, and safety glasses, hearing protection and a protective helmet. Put on
    anti-vibration gloves. It is believed that the causes of the so-called Raynaud’s disease, which affects the fingers, can be vibration and cold. Pallor and numbness
    fingers. Since the minimum burden at which the symptoms of this disease occur is unknown, precautions are strongly recommended. Try not to freeze, first of all keep your head, neck, feet, ankles, palms and wrists warm. Take breaks more often, do exercises with intensive use of hands to improve blood flow. Do not smoke. The saw chain must always be sharp. The saw, including the vibration protection system, should be carefully looked after. A dull chain increases the length of cut. When such a chain is pressed through a tree, the vibration load on the hands increases. Vibrations become even stronger with loose parts, damaged or worn dampers. Limit your work time. Even with all these precautions, it is impossible to exclude numbness of the fingers and the appearance of carpal tunnel syndrome. Therefore, with regular or constant use of the device, attention should be paid to the condition of the hands and fingers. If one of the symptoms described above is observed, immediately consult a doctor.
  • When handling fuel, care must be taken. Wipe up spilled fuel. Before starting the engine, carry the chain saw at least 3 m from the refueling point.
  • In places where mixing, transfusion, fuel storage or refueling is carried out, all potential sources of sparks and ignition should be eliminated. Not
    smoke when handling fuel and while using a chainsaw.
  • When starting the engine and while working with the saw, make sure that there are no strangers nearby. There should be no people or animals in the working area. When turned on and in
    During operation of the chainsaw, children, pets and all unauthorized persons must be at least 10 m away.
  • Start work only when the work area is free. Before work, make sure that you are in a stable position and the trunk does not fall on you after the cut. With the engine running, always hold the chainsaw firmly with both hands. Hold the chainsaw handles firmly with your fingers.
  • When the engine is running, be careful: do not allow the saw to touch parts of the body. Before starting the engine, make sure that the chain does not touch objects and
    people.
  • When carrying the chain saw, the engine must be turned off, the guide bar and chain must be pointing back, and the muffler should be at a distance from the body.
  • Before each use, check the components of the chain saw for wear, fastening strength and the need for replacement. If the chain saw is damaged, improperly configured, not fully assembled or not strong enough, it must not be used. Note that when the gas lever is released, the chain stops.
  • Except as noted in the user manual, only qualified personnel should perform maintenance on the chain saw (for example, using an inappropriate tool to disassemble the flywheel or hold the handwheel while disassembling the clutch can damage the flywheel structure, which could result in malfunction during operation )
  • Always turn off the engine before placing the chain saw.
  • When cutting small branches and shoots, be especially careful: small pieces can get stuck in the chain and be thrown towards the user.
  • Be careful when cutting a clamped or strained branch so that it does not hit you after releasing or relieving tension.
  • The handles must always be dry and clean, without traces of fuel or a combustible mixture.
  • Beware of recoil of the saw. Recoil. this is the upward movement of the guide bar that occurs when an object falls under the saw chain at the end of the guide bar. Kickback can cause a dangerous loss of control of the chain saw.
  • Before transporting the chain saw, be sure to put the protective cover on the guide bar. The device must be in
    A safe position where fuel leakage, device damage, and personal injury are excluded.
  • Precautions against kickback.

CAUTION!
Recoil is possible when the end of the guide bar hits an object or when the saw chain is clamped in the cut.

Contact of the end of the saw bar with any object can cause a lightning reaction: the guide bar is thrown up and towards the user. When the saw chain is clamped at the top of the guide bar, it is possible to quickly push the saw bar towards the user. Any of these reactions can result in loss of control of the saw and, as a result, serious injury.

  • Do not rely solely on the built-in saw guards. When using a chainsaw, certain measures should be taken to prevent accidents and injuries.

(1) If you know what leads to bestowal, you can weaken or eliminate the factor of surprise. Surprise is always fraught with danger of accident.
(2) With the engine running, confidently drive the saw with both hands: with your right hand on the rear handle, with your left. behind the front. Hold the handles firmly and confidently
with your fingers. Strong grip reduces the risk of kickback and allows you to confidently lead the saw. Do not loosen the grip.
(3) Make sure that there are no obstacles in the work area. Avoid contacting the end of the saw bar with a tree trunk, branches or other obstacles that may
meet while working with a saw.
(4) Saw at high speed.
(5) Do not perform work above shoulder height.
(6) Follow the sharpening and maintenance instructions of the chain saw manufacturer.
(7) Use only spare saw tires and chains specified by the manufacturer, or equivalent.
