ENGLISH
A
Danger!
Use only saw blades conforming to
standards and which are designed for
the maximum speed (see "Technical
specifications") – when using unsuit-
able or damaged saw blades, parts
might be hurled away explosive-like
by the centrifugal force.
Do not use:
− saw blades made of high speed
steel (HSS);
− damaged saw blades;
− cut-off wheel blades.
A
Danger!
− Mount saw blade using only gen-
uine parts.
− Do not use loose-fitting reducing
rings; the saw blade could work
loose.
− Saw blades have to be mounted
in such way that they do not wob-
ble or run out of balance and can
not work loose during operation.
Put outer blade flange (61) on –
8.
the two flanks must fit over the flats
of the saw spindle!
Screw on the arbor bolt (60) (left-
9.
handed thread!) and tighten with the
Allen key fingertight.
To arrest the saw blade, use the
saw blade lock (59).
A
Danger!
− Do not extend arbor bolt tighten-
ing wrench.
− Do not tighten arbor bolt by hit-
ting the assembly wrench.
10. Check the function. To do so, lower
the sawhead:
− The retractable blade guard must
open without touching the saw
blade or any other parts.
− When returning the sawhead in
the starting position the retracta-
ble blade guard must automati-
cally encompass the saw blade.
− In the upper starting position of
the sawhead the safety lock must
lock the retractable blade guard
to prevent unintentional opening.
− Check the saw blade lock – the
saw blade must turn freely.

Drive belt tensioning

The drive belt, running on the right-hand
side of the sawhead behind a plastic
cover, needs to be re-tensioned if it can
be depressed more than 3 mm halfway
between the two pulleys.
To check, re-tension and change:
Remove the plastic cover (66):
1.
Loosen the screw (67) and detach
26
the engagement hook on the rear
side of the plastic cover.
2. Check belt tension by thumb pres-
sure.
If the drive belt needs to be re-ten-
sioned or replaced:
− Loosen the four motor screws by
approx. one turn.
− Re-tension or replace the drive
belt. To re-tension slide the motor
to the rear.
− Tighten motor fastening screws
crosswise.
Replace the plastic cover (66) and
3.
secure with the screw.

Kerf plate replacement

A
Danger!
If the table insert is damaged there is
a risk that small parts may become
stuck between table insert and the
saw blade, causing the saw blade to
jam. Replace damaged table inserts
immediately!
Swing the hinged fence (68) down.
1.
Take the fence (69) off.
2.
Lever the table insert (70) up with a
3.
screwdriver. Doing so will damage
the table insert; it can not be used
again.

4. Fit new table insert and let engage.
Reinstall the fence (69).
5.
66 Swing the hinged fence up (70) and
6.
secure it.

3. Using the two screws at the rear of
the fence (arrow) adjust the fence
position, until it is exactly 90° to the
saw blade with the rotating table
locked in the 0° position.
4. Tighten the fastening screws of the
fence.
5. Swing the hinged fence up and
secure it.
Mitre angle indicator adjustment
Adjust the indicator's (73) position
1.
by means of the screw (72), until the
value indicated coincides with the
