Operating Instructions
WARNING
Do not operate your power tool using the
starting throttle position, as you do not
have control of the engine speed.
In the event of an emergency, switch off
the engine immediately – move the slide
control / stop switch to 0 or STOP.
WARNING
Always stop the engine before putting a
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 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 chain. From time to
time, the catcher may be damaged or
12
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.
WARNING
Your 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 chainsaw,
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
chain specially authorized by STIHL for
this purpose. Generally, the specially
designed and hardened cutters of such
a 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 chain strikes a solid metal or other
very hard object in the material being cut
(such as a nail), the carbide tips or other
chain parts may break off and be
propelled at a high velocity away from
the 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 chain
may result in higher vibration levels.
Consequently, a STIHL MS 461
Magnum Rescue Saw equipped with
rescue 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,
natural disasters, etc., replace the
carbide-tipped rescue chain with a
normal woodcutting chain such as
36 RMC 3 / 36 RSC 3, as listed in this
MS 461 R
