  • For Electric Chainsaws: Simply plug it in and switch it on.

7. Allow the chainsaw to warm up for a few minutes before beginning any cutting. This helps optimize performance.

How to Stop the Chainsaw?

  1. If the chainsaw is running, release the throttle trigger to idle.
  2. Engage the chain brake by pushing the front handguard forward. This immediately stops the chain rotation.
  3. Switch Off (for Gas Chainsaws): Turn off the engine by switching the ignition switch to the “off” position.
  4. Unplug (for Electric Chainsaws): For electric chainsaws, unplug the tool to disconnect the power source.
  5. Once the chainsaw is off, set it down carefully, ensuring the chain is not in contact with the ground.

Following these steps each time you start and stop your chainsaw promotes safety and prolongs the tool’s lifespan.

Basic Chainsaw Cutting Techniques

Mastering basic cutting techniques is essential for effectively using a chainsaw. Whether you’re felling trees or cutting firewood, understanding these techniques will ensure efficiency and safety:

  1. Limbing: Limbing involves removing branches from a fallen tree or a standing tree trunk. Start at the base of the tree and work your way up, cutting branches close to the trunk in sections.
  1. Bucking: Bucking is cutting a felled tree into manageable sections. Begin by cutting a notch, known as a kerf, on the underside of the log. Then, make a second cut from the top, meeting the notch to create a hinge. Finally, complete the cut from the opposite side.
  1. Cross-Cutting: Cross-cutting is cutting a log into shorter pieces. Place the log on a stable surface and cut perpendicular to its length. Use a sawhorse or other support to elevate the log if necessary.
  1. Trimming: Trimming involves cutting branches or limbs from a tree while standing. Position yourself safely, away from falling debris, and make controlled cuts to remove branches.
  1. Notching: Notching is crucial for the directional felling of trees. Make a horizontal cut, or notch, on the side of the tree facing your desired falling direction. Then, make a second cut, forming a wedge to guide the tree’s fall.
  1. Undercutting: Undercutting is the initial cut made at the base of a tree when felling it. Create a horizontal cut low on the trunk, aiming for one-third to half of the tree’s diameter. This undercut helps control the direction of the fall.
  1. Backcut: The backcut is made on the opposite side of the tree from the undercut. Begin the cut slightly above the level of the undercut, leaving a hinge that guides the tree’s fall.
  1. Proper Body Positioning: Maintain a stable stance with your feet shoulder-width apart while cutting. Keep a firm grip on the chainsaw with both hands and position your body to the side of the cutting path.

Practice these basic cutting techniques in a safe and controlled environment before tackling larger projects. Always prioritize safety by wearing appropriate protective gear and adhering to proper cutting procedures.
