Safety Safety definitions Safety instructions for operation Warnings, cautions and notes are used to point out specially important parts of the manual. WARNING: Used if there is a risk of injury or death for the operator or bystanders if the instructions in the manual are not obeyed. CAUTION: Used if there is a risk of damage to the product, other materials or the adjacent area if the instructions in the manual are not obeyed. Note: Used to give more information that is necessary in a given situation.
ladder, in a tree or where you do not have a firm ground to stand on. • • • Lack of concentration can lead to kickback if the kickback zone of the bar accidentally touches a branch, nearby tree or some other object. • • • • • • Never use the product by holding it with one hand. This product is not safely controlled with one hand. Always hold the product with both hands. The right hand should be on the rear handle, and the left hand on the front handle.
Chain brake and front hand guard Your product has a chain brake that stops the saw chain if you get a kickback. The chain brake decreases the risk of accidents, but only you can prevent them. The chain brake engages (A) manually by your left hand or automatically by the inertia release mechanism. Push the front hand guard (B) forward to engage the chain brake manually. B • • • • • • • • • • Most chainsaw accidents occur when the saw chain touches the operator.
applied maintenance on the saw chain and guide bar, decrease the risk of accidents. Right hand guard WARNING: Do not operate a product without a muffler or with a defective muffler. A defective muffler can increase the noise level and the risk of fire. Keep fire extinguishing tools near. Do not use a product without, or with a broken, spark arrestor mesh if you must have a spark arrestor mesh in your area. The muffler keeps the noise levels to a minimum and points the exhaust fumes away from the operator.
• Always move the product at least 3 m (10 ft) away from the refuelling area and fuel source before starting. • • • Keep the correct depth gauge setting. Obey the instructions and use the recommended depth gauge setting. Too large depth gauge setting 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 saw chain can derail.
Assembly Introduction WARNING: Read and understand the safety chapter before you assemble the product. To assemble the guide bar and saw chain (455 Rancher, 460 Rancher) 1.

5. Pull the starter rope handle quickly and with force. To stop the product 1. Push the start/stop switch down to stop the engine. Pull stroke and push stroke CAUTION: Do not pull the starter rope to full extension and do not let go of the starter rope handle. This can cause damage to the product. You can cut through wood with the product in 2 different positions. • To cut on the pull stroke is when you cut with the bottom of the guide bar. The saw chain pulls through the tree when you cut.
2. Cut approximately ⅔ through the trunk and then stop. Turn the trunk and cut from the opposite side. 1. To use the cutting technique WARNING: Use full throttle when you cut and decrease to idle speed after each cut. 2. To cut a trunk that has support on one end WARNING: Make sure that the trunk does not break during cutting. Obey the instructions below. CAUTION: Engine damage can occur if the engine runs for too long at full throttle without load. 1. Put the trunk on a saw horse or runners. 1.
2. Cut through the remaining part of the trunk on the push stroke to complete the cut. b) Select the applicable cutting technique for the tension in the branch. 1. 2. WARNING: Stop the engine if the saw chain gets caught in the trunk. Use a lever to open up the kerf and remove the product. Do not try to pull the product out by hand. This can result in injury when the product suddenly breaks free. To use the limbing technique Note: For thick branches, use the cutting technique.
a) Select the applicable cutting technique for the tension in the branch. 2. Make sure that no person is in the risk zone before or during felling. To calculate the felling direction WARNING: If you are not sure about how to cut the branch, speak to a professional chainsaw operator before you continue. Refer to To cut trees and branches that are in tension on page 20 for instructions on how to cut branches that are in tension.
complete. It is important that you hear sounds and warning signals. The felling hinge To clear the trunk and prepare your path of retreat The most important procedure during tree felling is to make the correct felling hinge. With a correct felling hinge, you control the felling direction and make sure that the felling procedure is safe. Cut off all branches from your shoulder height and down. The thickness of the felling hinge must be equal and a minimum of 10% of the tree diameter. 1.
To use the safe corner method The felling cut must be made slightly above the directional cut. WARNING: Be careful when you cut with the guide bar tip. Start to cut with the lower section of the guide bar tip as you make a bore cut into the trunk. b) Cut on the pull stroke through the remaining trunk. c) Cut straight into the trunk from the other side of the tree to complete the felling hinge. d) Cut on the push stroke, until ⅓ of the trunk is left, to complete the safe corner. 3.
5. Make one or more cuts of sufficient depth necessary to decrease the tension. Cut at or near the point of maximum tension. Make the tree or branch break at the point of maximum tension. The safest procedure is to use one of the following winches: • Tractor-mounted WARNING: Do not cut straight through a tree or branch that is in tension. WARNING: Be very careful when you cut a tree that is in tension. There is a risk that the tree moves quickly before or after you cut it.
1. If the temperature is 0˚C/32˚F or colder, carefully remove the plug in the cylinder cover. 2. If the temperature is -5˚C/23˚F or colder, assemble the winter cover on the starter housing.
