English WARNING Never touch a saw chain with your hand or any part of your body when the engine is running, even when the chain is not rotating. In the event of an emergency, switch off the engine immediately - move the Master Control Lever to STOP, 0 or †. WARNING Always stop the engine before putting the chain saw down. WARNING The saw chain continues to move for a short period after the throttle trigger is released (flywheel effect). Accelerating the engine while the saw chain is blocked increases the load and will cause the clutch to slip continuously. This may occur if the throttle is depressed for more than a few seconds when the saw chain is pinched in the cut or the chain brake is engaged. It can result in overheating and damage to important components (e. g. clutch, polymer housing components) - which can then increase the risk of injury, e. g., from the saw chain moving while the engine is idling. WARNING Your chain saw is equipped with a chain catcher. It is designed to reduce the risk of personal injury in the event of a thrown or broken saw chain. From time to time, the catcher may be damaged or removed. To reduce the risk of personal injury, do not operate a chain saw with a damaged or missing chain catcher. WARNING Inspect antivibration elements periodically. Replace damaged, broken or excessively worn antivibration elements immediately, since they may result in loss of control of the saw. A "sponginess" in the feel of the saw, increased vibration or increased "bottoming" during normal operation may indicate damage, breakage or excessive wear. Antivibration elements should always be replaced in sets. If you have any questions as to whether the antivibration elements should be replaced, consult your STIHL servicing dealer. If this chain saw 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. Check in particular that the fuel system is tight (no leaks) and that the controls and safety devices are working properly. Do not continue operating this chain saw if it is damaged. In case of doubt, have it checked by your STIHL servicing dealer. Your chain saw is not designed for prying or shoveling away limbs, roots or other objects. Such use could damage the cutting attachment or AV system. Unlike a conventional chain saw, however, this Rescue Saw may also be used in an emergency situation to cut through materials other than pure wood - if it is equipped with the carbide-tipped saw chain specially authorized by STIHL for this purpose. Generally, the specially designed and hardened cutters of such a saw chain can penetrate most wooden doors (even if nails are encountered), thin metal sheets, glass (e.g., train windows), insulating materials, as well as frame, stucco and even some lightweight masonry walls. WARNING If the saw chain strikes a solid metal or other very hard object in the material being cut (such as a nail), the carbide tips or other saw chain parts may break off and be propelled at a high velocity away from the chain saw. Try to avoid striking such objects where possible, and always stand to the left of the plane of the cutting attachment. WARNING When making a forced entry through a wall, be aware of the possibility of encountering electrical wiring and pipes. Cutting into such objects will increase the risk of serious or fatal injury from electrocution, fire and/or explosion. To the extent possible, make sure no live electrical wires or pipes carrying flammable or toxic substances are in or on the other side of the wall you intend to cut. Follow all applicable rules and guidelines in this regard. The extraordinary cutting capabilities of the STIHL carbide-tipped rescue saw chain may result in higher vibration levels. Consequently, a STIHL Rescue Saw equipped with rescue saw chain should be limited to occasional use only, i.e. short emergency and rescue cutting operations (max. 2 tank fillings daily). If daylong use for woodcutting is anticipated, such as clearing windfalls, 14 MS 461 R

WARNING
Never touch a saw chain with your hand
or any part of your body when the engine
is running, even when the chain is not
rotating.
In the event of an emergency, switch off
the engine immediately – move the
Master Control Lever to
STOP
,
0
or
†
.
WARNING
Always stop the engine before putting
the chain saw down.
WARNING
The saw chain continues to move for a
short period after the throttle trigger is
released (flywheel effect).
Accelerating the engine while the saw
chain is blocked increases the load and
will cause the clutch to slip continuously.
This may occur if the throttle is
depressed for more than a few seconds
when the saw chain is pinched in the cut
or the chain brake is engaged. It can
result in overheating and damage to
important components (e. g. clutch,
polymer housing components) – which
can then increase the risk of injury, e. g.,
from the saw chain moving while the
engine is idling.
WARNING
Your chain saw is equipped with a chain
catcher. It is designed to reduce the risk
of personal injury in the event of a
thrown or broken saw chain. From time
to time, the catcher may be damaged or
removed. To reduce the risk of personal
injury, do not operate a chain saw with a
damaged or missing chain catcher.
WARNING
Inspect antivibration elements
periodically. Replace damaged, broken
or excessively worn antivibration
elements immediately, since they may
result in loss of control of the saw. A
"sponginess" in the feel of the saw,
increased vibration or increased
"bottoming" during normal operation
may indicate damage, breakage or
excessive wear. Antivibration elements
should always be replaced in sets. If you
have any questions as to whether the
antivibration elements should be
replaced, consult your STIHL servicing
dealer.
If this chain saw 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. Check in
particular that the fuel system is tight (no
leaks) and that the controls and safety
devices are working properly. Do not
continue operating this chain saw if it is
damaged. In case of doubt, have it
checked by your STIHL servicing dealer.
Your chain saw is not designed for
prying or shoveling away limbs, roots or
other objects. Such use could damage
the cutting attachment or AV system.
Unlike a conventional chain saw,
however, this Rescue Saw may also be
used in an emergency situation to cut
through materials other than pure wood
– if it is equipped with the carbide-tipped
saw chain specially authorized by STIHL
for this purpose. Generally, the specially
designed and hardened cutters of such
a saw chain can penetrate most wooden
doors (even if nails are encountered),
thin metal sheets, glass (e.g., train
windows), insulating materials, as well
as frame, stucco and even some
lightweight masonry walls.
WARNING
If the saw chain strikes a solid metal or
other very hard object in the material
being cut (such as a nail), the carbide
tips or other saw chain parts may break
off and be propelled at a high velocity
away from the chain saw. Try to avoid
striking such objects where possible,
and always stand to the left of the plane
of the cutting attachment.
WARNING
When making a forced entry through a
wall, be aware of the possibility of
encountering electrical wiring and pipes.
Cutting into such objects will increase
the risk of serious or fatal injury from
electrocution, fire and/or explosion. To
the extent possible, make sure no live
electrical wires or pipes carrying
flammable or toxic substances are in or
on the other side of the wall you intend
to cut. Follow all applicable rules and
guidelines in this regard.
The extraordinary cutting capabilities of
the STIHL carbide-tipped rescue saw
chain may result in higher vibration
levels. Consequently, a STIHL Rescue
Saw equipped with rescue saw chain
should be limited to occasional use only,
i.e. short emergency and rescue cutting
operations (max. 2 tank fillings daily). If
daylong use for woodcutting is
anticipated, such as clearing windfalls,
