Cutting instruction
1. Leave supporting limbs till last
2. Slide support logs under trunk
Limbing
Don't saw above chest height.
Limbing a fallen tree is much the same as bucking.
Never remove a limb from a tree while it is supporting your
weight.
Be careful of the tip touching other limbs.
Always use both hands.
Don't cut with the saw overhead or the bar in a vertical posi-
tion.
If the saw should kickback, you may not have good enough
control to prevent possible injury.
Know how limb is stressed
Bucking
Stay on the uphill side of logs.
Bucking is the sawing of a log or fallen tree into smaller pieces.
There are a few basic rules which apply to all bucking opera-
tions.
Keep both hands on the handles at all times.
Support logs if possible.
When cutting on a slope or hillside, always stand uphill.
No standing on log.
