13. Press the throttle briefly as soon as the motor starts.
This disengages the half-throttle position and the
choke (if previously engaged), and the motor then
runs at idling speed when the throttle is released.
7.2 Cutting techniques
DANGER
Always hold the saw and the saw carriage securely
with both hands on the grips provided. Keep the grips
dry, clean and free from oil and grease.
DANGER
Check that no persons are present within the working
area and, in particular, in the area ahead of the saw
(in the cutting direction).
DANGER
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.
CAUTION
Secure the workpiece and the part to be cut off in
order to prevent uncontrolled movement.
NOTE
Always apply full throttle when cutting.
NOTE
Avoid making excessively deep cuts. Cutting through
thick workpieces should be accomplished, as far as
possible, by making a several cuts.
8 Care and maintenance
WARNING
Set the switch to "stop" before carrying out any main-
tenance or repairs and before cleaning the machine.
8.1 Maintenance
8.1.1 Each day before use
Check that the machine is complete and in faultless
condition. Have it repaired if necessary.
Check the machine for leakage. Have it repaired if ne-
cessary.
Check the machine for dirt and dust and clean it if
necessary.
Check that all operating controls function correctly. Have
them repaired if necessary.
7.2.1 Avoiding stalling 8
CAUTION
Avoid applying excessive pressure when cutting and
don't allow the cutting disc to stick and stall. Don't
attempt to cut to great depth immediately. Applica-
tion of excessive pressure increases the risk of cutting
disc distortion. Allowing the cutting disc to stick or stall
increases the probability of kickback or disc breakage.
CAUTION
Support slabs or large workpieces so that the kerf
remains open during the cutting operation.
7.2.2 Avoiding kickback 9
CAUTION
Always bring the machine into contact with the work-
piece from above. Allow the cutting disc to contact
the workpiece only at a point below its rotational axis.
CAUTION
Take special care when inserting the cutting disc in
an existing kerf.
7.3 Stopping the motor
WARNING
If the motor cannot be stopped by operating the on /
off switch, the motor must be stopped, if need be, by
pulling the choke lever.
WARNING
Do not lay the machine down until the cutting disc
has stopped rotating. The machine must always be
stored and transported in an upright position.
1. Release the throttle trigger.
2. Move the start / stop switch to the "stop" position.
Check that the cutting disc is in faultless condition. Re-
place it if necessary.
8.1.2 Every 6 months
Check the tightness of all screws and nuts accessible
from the outside.
Check that the fuel filter is clean (no dirt or deposits) and
replace it if necessary.
Retension the drive belt if it slips when the cutting disc is
under load.
8.1.3 When necessary
Check the tightness of all screws and nuts accessible
from the outside.
Replace the air filter if the machine doesn't start or motor
performance drops noticeably.
Check that the fuel filter is clean (no dirt or deposits) and
replace it if necessary.
