needed. To do this, briefly cut through
abrasive material, e. g., sandstone,
aerated concrete or asphalt.
WARNING
Do not use diamond abrasive chains for
rough grinding. Large bending stresses
occur during such work, which may
cause diamond abrasive chains to
shatter or break and result in serious or
fatal injury.
WARNING
To reduce the risk of injury from
shattered diamond abrasive chains:
1. Do not cut any material for which the
diamond abrasive chain is not
authorized.
2. Do not grind with the side of the
diamond abrasive chain.
3. Do not twist, thrust, knock or drop
the machine. This can cause
damage to the diamond abrasive
chain.
Do not use excessive force to push the
diamond abrasive chain into the work.
Do not cock, jam or wedge the diamond
abrasive chain in the cut.
WARNING
Inspect antivibration elements
periodically. Replace damaged, broken
or excessively worn antivibration
elements immediately, since they may
result in loss of control of the concrete
cutter. A "sponginess" in the feel of the
concrete cutter, increased vibration or
increased "bottoming out" during normal
operation may indicate damage,
GS 461
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 concrete cutter is not designed for
prying or shoveling objects. Such use
could damage the cutting attachment or
AV system.
WARNING
Never modify your muffler. Any
modification could cause an increase in
heat radiation, sparks or sound level,
thereby increasing the risk of fire, burn
injury or hearing loss. You may also
permanently damage the engine. Have
your muffler serviced and repaired by
your STIHL servicing dealer only.
WARNING
The muffler and other parts of the engine
(e.g. fins of the cylinder, spark plug)
become hot during operation and remain
hot for a while after stopping the engine.
To reduce risk of burns, do not touch the
muffler and other parts while they are
hot. Keep the area around the muffler
clean. Remove excess debris. Let the
machine cool down sitting on concrete,
metal, bare ground or solid wood away
from any combustible substances.
WARNING
An improperly mounted or damaged
cylinder housing or a
damaged/deformed muffler shell may
interfere with the cooling process of the
muffler. To reduce the risk of fire or burn
injury, do not continue work with a
damaged or improperly mounted
cylinder housing or a
damaged/deformed muffler shell.
Your muffler is furnished with a spark
arresting screen designed to reduce the
risk of fire from the emission of hot
particles. Never operate your unit with a
missing or damaged spark arresting
screen. If your gas/oil mix ratio is correct
(i.e., not too rich), this screen will
normally stay clean as a result of the
heat from the muffler and need no
service or maintenance. If you
experience loss of performance and you
suspect a clogged screen, have your
muffler maintained by a STIHL servicing
dealer. Some state or federal laws or
regulations may require a properly
maintained spark arrestor for certain
uses. See the "Maintenance, Repair and
Storing" section of these Safety
Precautions.
Reactive Forces
WARNING
Reactive forces may occur any time the
chain is rotating. Reactive forces can
cause serious personal injury. The
powerful force used to cut through a
workpiece can be reversed and work
against the operator. If the rotating chain
is suddenly stopped by contact with any
solid object or by a pinch or binding,
reactive forces can occur instantly and
may result in the operator losing control
of the concrete cutter, which, in turn,
may result in serious or fatal injury.
