Stihl MS 192 T Instruction Manual page 11

When working with a lifeline there is a
risk of cutting through the rope – to
reduce the risk of fall injuries , always
use double lifelines.
Take special care when cutting through
a limb. Hold the machine firmly to control
and counteract the feed force. Note
when reaching the end of a cut that the
saw is no longer supported in the kerf.
You have to take the full weight of the
saw since it might otherwise go out of
control – increased risk of accidents.
Make sure your saw does not touch any
foreign materials: Stones, nails, etc. may
be flung off and damage the saw chain.
The saw may kick back unexpectedly –
risk of accidents.
Warning! To avoid risk of
electrocution, take extra
precautions when cutting
near power lines. Have
the power switched off
before starting cutting
work in the immediate
vicinity of power lines.
Do not underbuck freely hanging limbs
because the chain may get pinched and
cause kickback and loss of control.
To reduce the risk of injury, take special
care when cutting shattered wood
because of the risk of injury from slivers
being caught and thrown in your
direction.
After finishing a cut, activate the chain
brake to lock the chain or shut off the
engine before moving the saw to
another position in the tree.

Cutting techniques:
Begin cutting with the saw at full throttle
and (if possible) engage the spiked
bumper firmly in the wood, and then
continue cutting.
Always work with the spiked bumper so
that you have better control of the saw. If
you work without the spiked bumper the
saw may pull you forwards suddenly.
Always pull the saw out of the cut with
the chain running.
Cut straight through thin limbs
–
In case of thick limbs, first perform
–
relieving cut from below (approx. 1/5
of diameter), then buck from above
Support and secure heavy
–
branches with ropes.
If the saw gets pinched in the cut:
Shut off the engine and secure the
–
saw to the tree – in direction of
trunk.
Carefully free the saw from the cut,
–
using another saw if necessary.
Limbs under tension:
Always start relieving cut 1) at the
N
compression side (A).
Make relieving cut (1) and then
N
perform bucking cut (2) at the
tension side (B) – the saw will
otherwise pinch or kick back.
If not otherwise possible, make the
bucking cut from the bottom upwards
(underbuck) – be wary of pushback.
Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands (whitefinger
disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
Hand protection (wearing warm
–
gloves)
Work breaks
–
