brake. If a kickback occur when you use the product, hold tight around the handles and do not let go. Chain catcher The chain catcher catches the saw chain if it breaks or comes loose. If you have the correct chain tension, the risk decreases. You also decrease the risk if you do the correct maintenance on the guide bar and saw chain. See Assembly on page 12 and Maintenance on page 23 for instructions.
• • • • • • Do not let battery acid touch your skin. Battery acid causes injuries to the skin, corrosion and burns. If you get battery acid in your eyes, do not rub but flush with water for minimum 15 minutes. If battery acid has touched your skin, you must clean the skin with a large quantity of water and soap. Get medical aid. Use the battery in temperatures between -10 °C (14 °F) and 40 °C (104 °F). Do not clean the battery or the battery charger with water. See Maintenance on page 23.
• Keep the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback. • Make sure that the saw chain has the correct tension! If the saw chain is not tight against the guide bar, the risk for it to come loose increases. This leads to increased wear on the guide bar, saw chain and drive sprocket. • Do maintenance on the cutting equipment regularly and keep it correctly lubricated.

We recommend you to do this each time before you use the product. Second, the kickback must be intense to engage the chain brake.
• To cut on the push stroke is when you cut with the top of the guide bar. The saw chain pushes the product in the direction of the operator. WARNING: Be careful when you cut on the push stroke. If the saw chain gets trapped in the trunk, the product can be pushed at you. You must prevent this force or there is a risk that the kickback zone of the guide bar touches the tree. This will lead to a kickback.
2. Cut limbs one by one. 3. Cut branches that are in tension from the bottom up. 1 3 2 1. Cut on the push stroke approximately 1/3 through the trunk. 2. Cut through the trunk on the pull stroke until the two kerfs touch. 4 4. Cut branches piece by piece if necessary. 2 1 3 To cut a trunk with support on two ends WARNING: Follow the steps below to prevent the saw chain from getting trapped in the trunk. 1. Cut on the pull stroke approximately 1/3 through the trunk. 2.
To use the tree felling technique WARNING: You must have much experience to fell a tree. Operators without experience must not fell trees. 6. Do not let the tree fall onto a different tree. It is dangerous to remove a trapped tree and there is a high accident risk. See To free a trapped tree on page 22. To keep a safe distance 1. Make sure that persons around you keep a safe distance at a minimum of 2 1/2 tree lengths. 2. Make sure that no person is in the risk zone before or during felling.
2. Make sure that the directional cut line is perfectly horizontal and at right angles (90°) to the felling direction. The directional cut line goes through the point where the two directional cuts touch. 1 3 2 1 1 2 To fell a tree You use three cuts to fell a tree. These are the directional cuts, which include the top cut and the bottom cut, and the felling cut. If you make these cuts correctly, you can control the felling direction very accurately.
5. Complete the felling cut parallel with the directional cut line. Make sure that the distance between them is at a minimum of 1/10 of the trunk diameter. The section of the trunk that is not cut is the felling hinge. The felling hinge controls the felling direction. To free a trapped tree WARNING: It is very dangerous to remove a trapped tree and there is a high accident risk. Keep out of the risk zone and do not try to fell a trapped tree.
risk that the tree moves quickly before or after you cut it. Serious injury can occur if you are in an incorrect position or if you cut incorrectly. 4.
