Tree cutting techniques and methods

1. Make sure that both hands hold the chain saw. Grab the rear handle with your right hand. Even if you are used to the left hand, you should grasp the handle with your thumb. You must stand firm when working.

2. Use the lower saw to fully open the throttle and hold the clamp before starting the saw.

3. Do not work when the engine is started, otherwise the throttle cannot be adjusted.

4. Within the working and damping range of the saw chain, no body parts shall be used.

5. When the chain rotates, the saw should be removed from the wood.

6. Clips must be used during work. The chainsaw will drive this person forward. Always pay attention to the surroundings, calm down and work clearly. Work only in areas with high light and visibility to avoid harming others.

7. Even if the chain saw is equipped with a catalytic exhaust muffler, do not work in a closed or poorly ventilated room to avoid poisoning.

8. Try to use a shorter guide. The chain, guide and sprocket must match the chain saw.

9. When working on slopes, the operator must stand on the top or side of the log. Pay attention to the rolling of trees to avoid the risk of being hit by stumps, branches and ditches. Do not stand on the trunk to mow the grass or cut the hanging branches from below. When cutting broken trees, please be aware that cracked wood chips may be dangerous.

10. When a rebound occurs, the chainsaw will suddenly lose control and rebound from the operator. If the chain at the end of the guide bar suddenly hits wood or hard objects, the chain will get stuck in the groove for a short time, causing a clip saw. Please note that when you leave a branch, you may accidentally encounter another branch.

11. When using the chainsaw, please hold and stabilize with both hands. The large throttle can be used to reduce the rebound of the chainsaw. Always observe the end of the guide, do not use the saw at the end of the guide. Please note that the chain may get stuck when cutting down solid trees and small trees.

12. Pay attention to the position of the torso and pay attention to the force that causes the gap to tighten. You can pinch the chain.

13. Only use sharp saw chains in accordance with the regulations and cut under the appropriate feed pressure. Pay attention to the sound of the motor, the sound of the chainsaw and the operating state must be consistent, and the sound of the motor can only be slightly reduced in the cutting groove. If the engine speed is too slow or the chain stops, you must immediately reduce the air supply pressure; otherwise the chainsaw will be damaged due to overheating of the engine.

14. If the saw is cut with the lower end of the guide plate (ie the right-hand saw), when the chain is caught or hit by other hard objects, the chain saw will be pushed into the luggage and must be fixed with clips. If you cut the saw with the upper end of its guide plate facing down, ie the saw is upside down, the chain will catch or hit other hard objects, the chain saw will rebound in the direction of the operator.

15. Before logging in, please note that only registry operators can remain in the registration area. There must be an inclined and unobstructed escape route. The working position around the suitcase is accessible. All operators must maintain a stable position.

16, especially the natural inclination of the trees, the branches are particularly dense, pay attention to the wind direction and the wind direction, the wind is too large to log in. The working position should be kept within a distance of 2.5 times the length of the felled trees, so as not to cut down will not endanger the safety of others, because the noise of the chainsaw can not hear the scream.

17. When cutting wood, remove branches and limbs from the logs and work area, remove the roots with an axe, and remove sand, stones, and other foreign objects that may cause saw chain wear. Determine the cutting direction and ensure that everyone's escape route is about 45 degrees behind the inclined direction. Clean the escape route and remove obstacles. The tools and tools are placed outside the safe distance, but not in the escape route. When logging in, people should stand next to the felled trees, run away from the side when in danger, and be careful of fallen branches when driving to the escape route.

18. When cutting large-diameter trees, a directional groove should be cut on the opposite side of the sawing surface. The saw groove is about one-fifth the diameter of the trunk, and the opening of the directional groove should not be greater than the depth. When cutting long trees with fibers, you should also see crack-proof grooves. The anti-crack groove can prevent the trunk from cracking when standing upside down.

19. When felling fallen branches or fallen trees, the operator must be extra careful because of the pressure caused by the trees intersecting. When working on the nozzle or near roads, railways and power lines, special attention should be paid to environmental conditions, and relevant departments should be notified in advance if necessary.

20. Try not to use the saw at the end of the guide plate, or cut multiple branches at the same time.

21. Pay attention to the tension of the branches, standing upright or level with the tension tree, always saw the pressure side, unload the saw groove, and then saw the groove on the tension side otherwise, the chain will be caught or rebound. If there is no other possibility, the blade slot will be separated from bottom to top, the blade slot will be reversed, the flat logs and the blade slot will not touch the ground or damage the saw chain. Saw thin wood, use a sturdy tripod, don't step on the wood with your feet, and don't let others pinch or help.
