Replacing The Bar And Chain - Ryobi RCS5133C Traduction Des Instructions Originales

WARNING
Never climb into a tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any position which may
cause you to lose your balance or control of the saw.
■ When pruning trees it is important not to make the
flush cut next to the main limb or trunk until you have
cut off the limb further out to reduce the weight. This
prevents stripping the bark from the main member.
1. Underbuck the branch 1/3 through for your first cut (A).
2. Overbuck the branch to drop it (B).
3. Finish by cutting smoothly and neatly against the main
member (C) so the bark will grow back to seal the
wound.
WARNING
If the limbs to be pruned are above chest height, hire a
professional to perform the pruning.
CUTTING SPRING POLES
See figure 37.
A spring pole (A) is any log, branch, rooted stump, or
sapling which is bent under tension by other wood so that
it springs back if the wood holding it is cut or removed.
On a fallen tree, a rooted stump has a high potential of
springing back to the upright position during the bucking
cut to separate the log from the stump. Watch out for
spring-poles; they are dangerous.
WARNING
Spring poles are dangerous and could strike the
operator causing the operator to lose control of the
chainsaw. This could result in severe or fatal injury to
the operator.
