forces on their working position, good support may be
sufficient to maintain a safe working position. However, as
operators move away from the trunk, they will need to take
steps to suppress or neutralize increasing lateral forces, for
example by redirecting the main rope through an additional
anchor point or using an adjustable strap directly from the
harness Has an additional anchor point.
The obtaining of a good support to the working position can
be favored by the use of a foot stirrup created by an endless
sling.
c. Starting the saw in the tree
When starting the saw in the shaft, the operator should:
- Apply the chain brake before starting, and
- Hold the saw on the left side, either on the right side before
starting:
∫
On the left side, hold the saw with your left hand on the
front handle while holding the saw away from the body while
pulling the starter rope with your right hand, or
∫
On the right side, hold the saw with your right hand on one
of the two handles while holding the saw away from the body
while pulling the starter rope with your left hand.
- The chain brake should always be engaged before lowering
a running saw to its stroke.
- Operators should always check that the saw has sufficient
fuel before undertaking critical cuts.
d. Using the chain saw with one hand
Operators should not use chain saws to prune single-handed
trees when they are in an unstable working position and
prefer hand saws when cutting wood of small diameter at the
ends of the branches.
Only chainsaws should be used for tree pruning with one
hand when:
- Operators cannot maintain a working position allowing them
to use both hands
- They need to maintain their working position, allowing them
to use both hands
- The saw is used in full extension, perpendicular to the body
of the operator and separated from it.
