Prohibited Use - Oleo-Mac GST 250 Manuel D'utilisation Et D'entretien

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 preference 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 (Fig. 20).
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.
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 trunk 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 chain
saw 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.

PROHIBITED USE

WARNING - Always follow the safety
regulations. This chain saw is designed
and built for pruning and tending standing
trees or shrubs. It is forbidden to cut other
types of material. Vibrations and kickback
vary with different materials and the
requirements of the safety regulations would
not be respected. Do not use the chainsaw as
a lever for lifting, moving or splitting objects.
Do not lock it over fixed stands. It is forbidden
to hitch tools or applications to the P.t.o. that
are not specified by the manufacturer.
WARNING - Do not use the pruning chain
saw for felling or bucking trees.
OPERATING INSTRUCTIONS
LIMBING
a) Always start from the larger diameter and
move towards the tip to cut off limbs and any
secondary branches.
b) Always find the safest and most stable
position before accelerating the chainsaw. If
necessary, keep your balance by resting your
knee on the trunk itself.
c) Keep the chainsaw on the trunk so as not to
get too tired, turning it onto the left- or right-
hand side depending on the position of the
branch to cut (Fig. 22).
d) In the case of branches under tension, find a
safe position to protect yourself if they whip
back. Always start the cut from the opposite
side to the bend.
e) When lopping large diameter branches make
use of the bumper spike.
WARNING - Do not use the upper edge
of the tip of the guide bar to cross-cut;
otherwise you might risk a kickback.
