Limbing a felled tree
First check which way the limb is bent. Then make a
shallow cut into the compressed side to prevent the limb
from being torn. Cut through from the tensed side.
WARNING
Be alert to the spring back of a cut limb.
Pruning
Cut up from the bottom, finish down from the top.
WARNING
1. Do not use an unstable foothold or a stepladder.
2. Do not overreach.
3. Do not cut above shoulder height.
4. Always use both hands to grip the saw.
Working with tree service chain-saws from rope and
harness
General requirements
Operators of tree service chain-saws working at height
from a rope and harness should never work alone. A
ground worker trained in appropriate emergency pro-
cedures should assist them. Operators of tree service
chain-saws for this work should be trained in general
safe climbing and work positioning techniques and be
properly equipped with harnesses, ropes, strops, cara-
biners and other equipment for maintaining secure and

safe working positions for both themselves and the
saw.
Preparing to use the saw in the tree
The chain-saw should be checked, fuelled, started and
warmed up by the ground worker and then switched off
before it is sent up to the operator in the tree.
The chain-saw should be fitted with a suitable strop for
attachment to the operator's harness:
a) secure the strop around the attachment point on the
b) provide suitable carabiners to allow indirect (i.e. via
c) ensure the saw is securely attached when it is being
d) ensure the saw is secured to the harness before it is
The ability to directly attach the saw to the harness
reduces the risk of damage to equipment when moving
around the tree. Always switch the saw off when it is
directly attached to the harness.
The saw should only be attached to the recommended
attachment points on the harness. These may be at mid-
point (front or rear) or at the sides. Where possible, at-
tach the saw to the centre rear mid-point to keep it clear
of climbing lines and to support its weight centrally down
the operator's spine.
