Operation Before Using the Chain Saw Before using the chain saw, do the following: • Clean and check the chain components for excessive wear or damage and replace them as needed; refer to Servicing the Guide Bar, Chain, and Drive Sprocket (page 18) and Sharpening the Chain (page 20). • Check the oil level; refer to Checking the Oil Level and Adding Bar and Chain Oil (page 17). • Check the chain brake; refer to Checking the Chain Brake (page 17). g192108 Figure 7 Starting the Chain Saw 1.
Shutting Off the Chain Saw Note: Keeping your left arm straight with your elbow locked helps reduce kickback. To shut off the chain saw, release the trigger. Whenever you are not using the saw or are transporting the saw to or from the work area, move the chain brake to the STOP position (Figure 8). Cutting with the Chain Saw WARNING Operating a chain saw improperly can cause serious person injury or death.
Pruning a Tree WARNING Cutting higher limbs from a tree off the ground can put you in an unstable position that could be unsafe for you while handling a chain saw, resulting in possible serious injury or death to you or bystanders. When cutting limbs from a standing tree, use the following practices: • Do not climb on limbs or branches with a chain saw. • Do not overreach, and cut with both hands on the chain saw. • Ensure that all bystanders are away from the area where branches may fall. 1.
Limbing a Fallen Tree 1. Grip the chain saw as shown in Figure 11. 2. Cut off the smaller limbs from the tree that are not supporting its weight off the ground. g194824 Figure 16 g212420 Figure 15 1. First cut 2. Second cut 3. Back cut 5. Make a second cut to form a notch, starting the cut at least 5 cm (2 inches) above and away from the first cut (Figure 15). 6.

Bucking a Log • If you are cutting branches from a fallen tree or cutting a log into lengths, support the log off the ground (preferably on a sawbuck); refer to Figure 19. g194820 Figure 19 • If the log is supported on an end, cut from the top. If the chain saw binds in the cut, do not attempt to free it by running the motor. Shut off the saw, then use a wedge to pry open the cut and release the saw.
