Stihl TS 410 Instruction Manual page 9

Ensure proper ventilation when working
in trenches, hollows or other confined
locations – risk of serious or fatal
injury from breathing toxic fumes!
If you feel sick, if you have a headache,
vision problems (e.g., your field of vision
gets smaller), hearing problems,
dizziness or inability to concentrate, stop
work immediately. Such symptoms may
be caused by an excessively high
concentration of exhaust emissions –
risk of accident!
No smoking when working with or near
the machine - risk of fire!
If the machine is subjected to unusually
high loads for which it was not designed
(e.g., heavy impact or a fall), always
check that it is in good condition before
continuing work - refer also to the
section "Before starting". Check the fuel
system for leaks and make sure the
safety devices are working properly.
Never use the machine if it is not in good
condition. Consult a servicing dealer if in
doubt.
Do not work in the starting throttle
position, as the engine speed cannot be
controlled in this position.
Never touch a rotating cutting wheel with
your hand or any other part of the body.
Examine the workplace. Avoid all
danger due to damaged piping or
electrical wiring.
The machine must not be used near
inflammable substances or gases.
Never use the machine to cut inside
pipes, metal troughs or other containers
unless you are absolutely sure that they
do not contain any volatile or
inflammable substances.
TS 410, TS 420
Never leave the machine unattended
with the engine running. Switch off the
engine before leaving the machine
(e. g., for a break).
Before putting the cut-off machine down
on the ground:
– Switch off engine
– Wait until the cutting wheel has
come to a standstill or brake the
cutting wheel until it comes to a
standstill by carefully touching a
hard surface (e. g., concrete slab)
Inspect cutting wheel fre-
quently – replace
immediately if there is
evidence of cracking,
warping or other damage
(e. g., overheating) – risk
of accident due to
breakage!
In the event of changes in cutting
behavior (e. g., increased vibration,
reduced cutting performance), stop work
and eliminate the causes of the
changes.
Reactive forces
The most frequently occurring reactive
forces are kickback and pull-in.
Dangers of kickback
Kickback can result in fatal cuts.
Kickback occurs when the cut-off
machine is suddenly thrown up and back
in an uncontrolled arc towards the
operator.
Kickback occurs if, for example, the
cutting wheel
– becomes jammed – above all in the
upper quarter
– is severely braked through frictional
contact with a solid object
Reduce the risk of kickback
– Work cautiously and methodically
– Hold the cut-off machine firmly with
both hands and maintain a secure
grip
– Do not use the upper quarter of the
cutting wheel for cutting. The cutting
wheel must be introduced into the
cut with extreme care, without
twisting and without pushing
