CUTTING INSTRUCTIONS GENERAL [NOTE] Read the ECHO “CHAIN SAW SAFETY MANUAL” included with your chain saw for additional cutting and safety instructions. In all circumstances the operation of the chain saw is a one-man job. It is difficult at times to take care for your own safety, so don’t assume the responsibility for a helper as well. After you have learned the basic techniques of using the saw, your best aid will be your own good common sense...
A falling tree can seriously damage anything it may hit - a car, a house, a fence, a powerline, or another tree. There are ways to make a tree fall where you want it, so first decide where that is! FELLING A TREE DIRECTION OF FALL Before cutting, clear the area around the tree. You will need good footing while working and you should be able to work the saw without hitting any obstacles. Next, select a path of retreat.
Don’t cut with the saw overhead or the bar in a verticle position. If the saw should kick back you may no have good enough control to prevent possible injury. BUCKING Bucking is the sawing of a log or fallen tree into smaller pieces. There are a few basic rules which apply to all bucking operations. Uphill position Keep both hands on the handles at all times. Support logs if possible. When cutting on a slope or hillside, always stand uphill.
