WORKING TECHNIQUES Securing the work position for two-handed use To allow the operator to hold the saw with both hands, they should as general rule, aim for secure work position where they are operating the saw at: • hip level when cutting horizontal sections. • solar plexus level when cutting vertical sections. Where the operator is working close into vertical stems with a low lateral forces on their work position, then a good footing may be all that is needed to maintain a secure work position. However as operators move away from the stem, they will need to take steps to remove or counteract the increasing lateral forces by, for example, a re-direct of the main line via a supplementary anchor point or using an adjustable strop direct from the harness to a supplementary anchor point. The chain brake should always be engaged before lowering a running saw onto its strop. Operators should always check the saw has sufficient fuel before undertaking critical cuts. One-hand use of the chainsaw Operators should not use tree service chainsaws onehanded in place of unstable work positioning or in preferance to a handsaw when cutting small diameter wood at the branch tips. Tree service chainsaws should only be used one-handed where: • the operator cannot gain a work position enabling two- handed use; and • they need to support their working position with one hand; and • the saw is being used at full stretch, at right angles to and out of line with the operator's body. Gaining a good footing at the working position can be assisted by use of a temporary foot stirrup created from an endless sling. Starting the saw in the tree When starting the saw in the tree, the operator should: a) apply the chain brake before starting. b) hold saw on either the left or right of the body when starting: 1 on the left side hold the saw with the left hand on the front handle and thrust the saw away from the body while holding the pull starter cord in the other hand. 2 on the right side, hold the saw with the right hand on either handle and thrust the saw away from the body while holding the pull starter cord in the left hand. Operators should never: • cut with the kickback zone at the tip of the chainsaw guide bar. • 'hold and cut' sections. • attempt to catch falling sections. • Cut in the tree when he/she is only secured with one rope, always use 2 secured lines. Freeing a trapped saw If the saw should become trapped during cutting, operators should: • switch off the saw and attach it securely to the tree inboard (i.e. towards the truck side) of the cut or to a separate tool line. • pull the saw from the kerf whilst lifting the branch as necessary. • if necessary, use a handsaw or second chainsaw to release the trapped saw by cutting a minimum of 30 cm away from the trapped saw. Whether a handsaw or a chainsaw is used to free a stuck saw, the release cuts should always be outboard (toward the tips of the branch), in order to prevent the saw being taken with the section and further complicating the situation.

Securing the work position for two-handed use
To allow the operator to hold the saw with both hands,
they should as general rule, aim for secure work position
where they are operating the saw at:
•
hip level when cutting horizontal sections.
•
solar plexus level when cutting vertical sections.
Where the operator is working close into vertical stems
with a low lateral forces on their work position, then a
good footing may be all that is needed to maintain a
secure work position. However as operators move away
from the stem, they will need to take steps to remove or
counteract the increasing lateral forces by, for example, a
re-direct of the main line via a supplementary anchor
point or using an adjustable strop direct from the harness
to a supplementary anchor point.
Gaining a good footing at the working position can be
assisted by use of a temporary foot stirrup created from
an endless sling.
Starting the saw in the tree
When starting the saw in the tree, the operator should:
a) apply the chain brake before starting.
b) hold saw on either the left or right of the body when
starting:
1
on the left side hold the saw with the left hand on the
front handle and thrust the saw away from the body
while holding the pull starter cord in the other hand.
2
on the right side, hold the saw with the right hand on
either handle and thrust the saw away from the body
while holding the pull starter cord in the left hand.
The chain brake should always be engaged before
lowering a running saw onto its strop. Operators should
always check the saw has sufficient fuel before
undertaking critical cuts.
One-hand use of the chainsaw
Operators should not use tree service chainsaws one-
handed in place of unstable work positioning or in
preferance to a handsaw when cutting small diameter
wood at the branch tips.
Tree service chainsaws should only be used one-handed
where:
•
the operator cannot gain a work position enabling two-
handed use; and
•
they need to support their working position with one
hand; and
•
the saw is being used at full stretch, at right angles to
and out of line with the operator’s body.
Operators should never:
•
cut with the kickback zone at the tip of the chainsaw
guide bar.
•
‘hold and cut’ sections.
•
attempt to catch falling sections.
•
Cut in the tree when he/she is only secured with one
rope, always use 2 secured lines.
Freeing a trapped saw
If the saw should become trapped during cutting,
operators should:
•
switch off the saw and attach it securely to the tree
inboard (i.e. towards the truck side) of the cut or to a
separate tool line.
•
pull the saw from the kerf whilst lifting the branch as
necessary.
•
if necessary, use a handsaw or second chainsaw to
release the trapped saw by cutting a minimum of 30
cm away from the trapped saw.
Whether a handsaw or a chainsaw is used to free a stuck
saw, the release cuts should always be outboard (toward
the tips of the branch), in order to prevent the saw being
taken with the section and further complicating the
situation.
