b) Avoid inhaling gasoline vapors and exhaust
fumes.
c) Hot exhaust gases containing sparks or sparks gen-
erated by the cutting operation may cause fire or
explosion. Take care to ensure that the sparks
generated do not ignite flammable (gasoline, dry
grass, etc.) or explosive (gas, etc.) substances.

5.7 Dusts
a) Large quantities of dust hazardous to the health are
generated when cutting (especially when dry cutting).
The operator and bystanders must wear suitable
dust masks while the machine is in use.
b) Dust or vapors containing chemical substances may
be generated when working on unknown materi-
als. These substances could cause serious damage
to the health. Obtain information about hazards
presented by the materials from the client or the
authorities responsible. The operator of the ma-
chine and any bystanders must wear respiratory
protection that is approved for use in conjunction
with the applicable substance.
c) To reduce the amount of dust generated when
cutting mineral materials and asphalt, we recom-
mend use of the wet cutting technique.
d) Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory diseases
to the operator or bystanders. Material containing
asbestos must only be treated by specialists. To re-
duce the amount of dust produced when cutting,
we recommend use of the wet cutting method.
Ensure that the workplace is well ventilated. The
use of a dust mask of filter class P2 is recommen-
ded. Follow national requirements for the materi-
als you want to work with.
5.8 Requirements to be met by users
a) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
b) Stay alert, watch what you are doing and use com-
mon sense when operating the machine. Don't
use the machine when you are tired or under the
influence of drugs, alcohol or medication. A mo-
ment of inattention while operating machines may
result in serious personal injury.

5.9 Safety warnings for abrasive cutting-off
operations
a) Check that the cutting disc is fitted in accordance
with the manufacturer's instructions.
b) Cutting discs must be stored and handled care-
fully in accordance with the manufacturer's in-
structions.
c) Use only cutting discs with a rated maximum
permissible speed which is at least as high as the
machine's highest running speed.
d) Cutting discs which are damaged or out of round
(causing vibration) must not be used.
e) The outside diameter and the thickness of the
cutting disc must be within the capacity rating of
the machine. Incorrectly sized accessories cannot
be adequately guarded or controlled.
f) Don't use toothed cutting discs (saw blades or
similar). Blades or discs of this kind frequently cause
kickback or loss of control of the machine.
g) Guide the machine evenly and do not apply lateral
pressure to the cutting disc. Always bring the
machine into contact with the workpiece at right
angles. Don't attempt to alter the line of cut by
applying lateral pressure or by bending the cutting
disc while cutting is in progress. This presents a
risk of damaging or breaking the cutting disc.
h) Don't attempt to brake the cutting disc with the
hand.
i) The cutting disc and flange or any other accessory
must fit the arbor of the machine exactly. Cutting
discs or accessories with arbor holes that do not
match the mounting hardware of the machine will run
out of balance, vibrate excessively and may cause
loss of control.
j) Always use undamaged disc mounting flanges of
the correct diameter for the cutting discs used.
Correctly sized flanges support the cutting disc and
thus reduce the possibility of disc breakage.
k) When fitting the cutting disc, always take care
to ensure that the disc's specified direction of
rotation corresponds to the direction of rotation
of the machine.
l) Store the cutting disc in accordance with the man-
ufacturer's recommendations. Incorrect or care-
less storage may damage the cutting disc.
m) Don't use cutting discs with a thickness greater
than 5.5 mm (0.22").
