10. Use your concrete cutter for cutting
only. It is not designed for prying or
shoveling away any objects.
11. Be especially alert for reactive
forces, when cutting with the front
and upper quadrant of the chain.
12. Be alert to shifting of the workpiece
or anything that could cause the cut
to close and pinch the chain,
especially in the upper quadrant.
Support the workpiece in such a
way that the cut remains open.
Never make a cut that results in a
binding of the chain.
13. Always use wet-cutting. In a pinch
situation the water can act as a
lubricant and reduce the energy of
reactive forces.
14. Release any pressure on the
concrete cutter as you reach the
end of the cut. Too much pressure
may cause the operator to lose
control of the concrete cutter when
the diamond abrasive chain
completes the cut. The chain may
contact the operator or strike some
foreign object and break.
15. Use extreme caution when
reentering a cut and do not turn the
chain at an angle or push the chain
into the cut as this may result in a
binding of the chain.
MAINTENANCE, REPAIR AND
STORAGE
Never operate a concrete cutter that is
damaged, improperly adjusted or not
completely or securely assembled.
Follow the maintenance and repair
instructions in the appropriate sections
of your instruction manual.
WARNING
Use only STIHL replacement parts for
maintenance and repair. Use of parts
manufactured by others may cause
serious or fatal injury.
WARNING
Always stop the engine and make sure
that the cutting tool is stopped before
doing any maintenance or repair work or
cleaning the power tool.
WARNING
Do not attempt any maintenance or
repair work not described in your
instruction manual. Have such work
performed only at your STIHL servicing
dealer.
Clean off grinding dust after finishing
work. Tighten all nuts, bolts and screws
except the carburetor adjustment
screws after each use.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage parts of the machine.
WARNING
Never test the ignition system with spark
plug boot removed from spark plug or
with an unseated spark plug, since
uncontained sparking may cause a fire.
WARNING
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot
snugly onto spark plug terminal of the
proper size. A loose connection between
spark plug terminal and ignition wire
connector in the boot may create arcing
that could ignite combustible fumes and
cause a fire. Keep spark plug clean, and
make sure ignition lead is in good
condition. Do not use a spark plug with a
detachable SAE adapter terminal.
Arcing may occur that could ignite
combustible fumes and cause a fire.
This can result in serious injuries or
damage to property.
WARNING
Do not operate your power tool if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Never touch a hot muffler or spill fuel or
other flammable liquid over it. Burn
injuries or fire will result. If your muffler
was equipped with a spark-arresting
screen to reduce the risk of fire (e. g. in
the USA, Canada and Australia), never
operate your power tool if the screen is
missing or damaged.
In California, it is a violation of § 4442 or
§ 4443 of the Public Resources Code to
use or operate gasoline-powered tools
on forest-covered, brush-covered or
grass-covered land unless the engine’s
exhaust system is equipped with a
complying spark arrester that is
maintained in effective working order.
