Safety Warning for rechargeable chain saws

1. Keep all parts of the body at arm’s length from the chainsaw while it is in operation. Before starting the chainsaw, make sure that the chain is not in contact with anything. Even a moment of distraction during chain saw operation may result in clothing or body being sucked into the chainsaw.

2. Be sure to hold the rear handle of the chainsaw with your right hand and the front handle with your left. Holding a chainsaw upside down increases the risk of personal injury, so do not hold the back handle with your left hand and the front handle with your right.

3. Because the chain may come into contact with hidden wires, only hold the insulated handle when operating the tool. When the chainsaw comes into contact with a live wire, the exposed metal part of the tool may also become live and cause an electric shock to the operator.

4. Wear safety glasses and ear protectors. It is recommended that you wear a protective device to protect your head, hands, legs and feet. Wearing protective clothing will reduce personal injury from flying debris or accidental contact with a chainsaw.

5. Do not operate a chainsaw in a tree. Operating a chainsaw in a tree can cause personal injury.

6. Be sure to stand firmly and to stand on a fixed, safe and level surface before operating the chainsaw. Slippery or unstable surfaces such as ladders can cause the body to lose its balance or the chainsaw to lose control.

7. When cutting a branch under tension, beware of a rebound. When the tension on the wood fibers is released, the elastic forces on the branches may strike the operator or the chain saw and cause it to lose control.

8. Be especially careful when cutting through shrubs and young trees. Slender materials may trap the chain and strike themselves or cause self-imbalance.

9. Close the chain saw and hold the front handle at arm’s length before carrying it.
   When transporting or storing chainsaws, always cover the guide plate. Proper operation of the chainsaw reduces the likelihood of accidental contact with the chain in motion.

10. Lubricate, tensify chains and replace accessories according to instructions. Improper tensioning or lubrication of chains may result in chain rupture or increase the likelihood of rebound.

11. Keep handles dry and clean, free of grease and grease. Greasy handles tend to slip and cause tools to slip out of control.

12. Used only for cutting wood. Do not use chain saws for purposes other than
    design. For example, do not use chain saws to cut plastic stone or non-wood building materials. Use them for operations other than design purposes can lead to dangerous situations.

13. Causes of tool bounces and precautions taken by operators:

    • Rebound may occur if the head of the guide plate touches an object or the wood grips and squeezes the chain during cutting.

    • Sometimes, the head of the guide plate touches an object, creating a sudden reaction force that bounces the guide plate and charges the operator.

    • Squeezing the chain along the top of the guide plate may push the guide plate back to the operator quickly.

    • Any of these counterforces can cause the chainsaw to go haywire and cause serious injury. Do not rely solely on safety equipment mounted on the chainsaw. As a chainsaw user, you should take a variety of measures to prevent accidental or personal injury during cutting.

    • Incorrect operation of the tool or incorrect operation steps or conditions will lead to a rebound, which can be avoided by following the following precautions:

    • With a firm grip, grip the chainsaw handle with both thumbs and the rest of your fingers, adjusting your body and arms to prevent rebound. The operator can control the recoil if the correct precautions are followed. Please be careful.

    • Do not extend the tool too far and do not cut above the shoulder. This helps prevent the guide head from touching the object and gives better control of the tool in unexpected situations.

    • Use only replacement guides and chains specified by the manufacturer Improper replacement guides and chains may cause chain breakage or rebound.

    • Maintain the chainsaw following the manufacturer’s polishing and maintenance instructions. Lowering the depth gauge will cause frequent bounces.
      Please keep this instruction manual.
      Warning: Do not be too familiar with the product (experience gained from repeated use) to not strictly follow the relevant product safety rules. Improper use or failure to follow the safety rules in the instructions can result in serious personal injury.

Apply slight pressure to the handle and continue to cut the saw, then pull the chainsaw back slightly and press the spines down slightly, and finally lift the handle to complete the cut.

Chain saw counter-thrust safety device

Chain brake
The chainsaw is equipped with a chain brake that stops both the motor and the chain when a kick occurs. During the backkick, the forward movement of the chain backkick brake handle causes the chain brake to work as the chain rotates backward. The inertial forces generated in the fast push back process also cause the chain brake to act.

Warning: Do not modify or attempt to disable chain brakes.Make sure the chain brake works properly before using the chainsaw. Chain back kick brake handle should be easy to move back and forth.
To test the operation of the chain brake, perform the following steps :

• Step 1: Place the chainsaw on a flat, exposed surface and ensure that no objects or obstacles are in contact with the guide plate and chain;
• Step 2: Release the chain brake by pulling the chain brake; Step 3: Start the chainsaw;
• Step 4: Push the chain kick brake handle toward the front of the saw. A properly operating hand brake will immediately stop the chain movement. If the chain brake does not work properly, do not use the chain saw until it has been repaired by a qualified maintenance technician.
  Warning: Make sure the chain brake works properly before each use.
  Warning: If the chain brake is blocked by wood chips, the function of the chain brake may degrade. Please keep the equipment clean at all times.
