16. Release the pressure on the cut-off
machine as you reach the end of the
cut. Too much pressure may cause
the operator to lose control of the
cut-off machine when the abrasive
wheel completes the cut. The
abrasive wheel may contact the
operator or strike some foreign
object and shatter.
17. Use extreme caution when
reentering a cut and do not twist the
wheel in the cut, turn it at an angle
or jam it into the cut as this may
result in a binding or pinching of the
wheel.
Gyroscopic Forces
Be alert for gyroscopic forces that are
caused by the rapid spinning of the cut-
off wheel. These forces result in
opposition to directional change, e.g.,
when the operator attempts to move the
machine in a sideways direction, and
can result in loss of control.
Maintenance, Repair and Storage of the
Cut-Off Machine
Never operate a cut-off machine that is
damaged, improperly adjusted or not
completely or properly assembled.
Follow the maintenance and repair
instructions in the appropriate sections
of this instruction manual.
WARNING
STIHL recommends the use of only
STIHL replacement parts for
maintenance and repair. Use of parts
manufactured by others may be
extremely dangerous and could result in
serious or fatal injury.
WARNING
Always shut off the machine and make
sure that the wheel is stopped before
doing any maintenance or repair work or
cleaning the cut-off machine. When the
machine is shut off, the wheel continues
to rotate for a few seconds. Do not
attempt any maintenance or repair work
not described in this manual as
appropriate for users. STIHL
recommends that you have all other
work performed at your authorized
STIHL servicing dealer.
Clean off dust and other cutting debris
after finishing work. Check and, if
necessary, tighten all nuts, bolts and
screws after each use.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage the machine or its
components.
WARNING
Never test the ignition system with the
spark plug boot removed from the 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
or property damage, use only spark
plugs authorized by STIHL. Always
press the spark plug boot snugly onto
the spark plug terminal of the proper
size. A loose connection between the
spark plug terminal and the ignition wire
connector in the boot may create arcing
that could ignite combustible fumes and
cause a fire. Keep the spark plug clean,
and make sure the 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 cut-off machine 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. Your muffler is equipped with a
spark-arresting screen to reduce the risk
of fire. Never operate your cut-off
machine if the screen is missing or
damaged.
WARNING
Operation of this equipment may create
sparks that can start fires around dry
vegetation. A spark arrester is required.
The operator should contact local fire
agencies for laws or regulations relating
to fire prevention requirements.
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.
The owner/operator of this product is
responsible for properly maintaining the
spark arrester. Other states or
governmental entities/agencies, such as
the U.S. Forest Service, may have
similar or additional requirements.
