5.9 Safety warnings for abrasive cutting-off
operations
en
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.

6 Before use

6.1 Fuel
NOTE
The two-stroke motor runs on a mixture of gasoline and
oil. The quality of the fuel mixture decisively influences
the running and life expectancy of the motor.
CAUTION
Avoid direct skin contact with gasoline.
8
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").
n) Remove the cutting disc from the machine af-
ter use. The cutting disc may suffer damage if the
machine is transported with the disc fitted.
o) Abrasive cutting discs for gasoline-powered cut-
off saws which are used for wet cutting must be
used up the same day as long periods of exposure
to moisture have a negative effect on the strength
of the disc.
p) Observe the expiry date for resin-bonded cutting
discs and don't use the discs after this date.
q) Resharpen polished diamond segments (no dia-
monds project from the segment matrix) by cut-
ting with the disc in a very abrasive material such
as sandstone.
r) Don't use damaged diamond cutting discs (cracks
in the steel disc, broken or polished segments,
damaged arbor hole, bent or distorted steel disc,
heavy discoloration due to overheating, steel disc
worn away beneath the segments, diamond seg-
ments with no lateral overhang, etc.)

5.10 Personal protective equipment

The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec-
tion, protective gloves and safety footwear while the
machine is in use.
CAUTION
Ensure that the workplace is well ventilated in order
to avoid breathing in gasoline fumes.
CAUTION
Use a fuel container that complies with the applicable
regulations.
CAUTION
Alkylate gasoline does not have the same density (specific
weight) as conventional gasoline. To avoid damage when
alkylate gasoline is used, the machine must be readjusted
