2. Remove the arbor bolt (51) from the
saw spindle (left-handed thread!).
3. Unlock the retractable blade guard
and open it.
4. Remove the following parts from the
saw spindle:
−
arbor bolt (51) ,
−
outer blade flange (52) ,
−
saw blade (53) ,
−
inner blade flange (54) .
5. Clean clamping surfaces of:
−
saw spindle,
−
inner blade flange,
−
saw blade,
−
outer blade flange,
−
arbor bolt.
A
Danger!
Do not use cleaning agents
(e.g. to remove resin residue) that
could corrode the light metal compo-
nents of the saw; the stability of the
saw would be adversely affected.
6. Put the inner blade flange (54) on
the saw spindle.
A
Danger!
Fit the inner blade flange cor-
rectly! Otherwise the saw may be
blocked, or the saw blade could work
loose! The inner blade flange is in the
correct position when the chamfered
collar (56) shows to the right and the
spring ring groove (55) shows to the
left.
7. Mount the new saw blade (53) –
observe the rotational direction (the
arrows on both saw blade and blade
guard must point in the same direc-
tion)!
A
Danger!
Use only saw blades conform-
ing to standards and which are
designed for the maximum speed
(see "Technical specifications") –
when using unsuitable 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.
8. Put outer blade flange (52) on –
the two flanks must fit over the flats
of the saw spindle!
9. Screw on the arbor bolt (51) (left-
handed thread!) and tighten with the
Allen key
fingertight .
To arrest the saw blade, use the
saw blade lock
(50) .
A
Danger!
−
Do not extend arbor bolt tighten-
ing wrench.
−
Do not tighten arbor bolt by hit-
ting the assembly wrench.
10. Check 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.
9.2 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:
1. Remove the plastic cover (57) :
remove screw (58) and unhook the
plastic cover's snap-in hook at the
rear.
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.
3. Replace the plastic cover (57) and
secure with the screw.
9.3 Kerf plate replacement
A
Danger!
With a damaged table insert,
there is a risk of small parts getting
stuck between table insert and saw
blade, blocking the saw blade.
Replace damaged table inserts imme-
diately!
1. Swing the hinged fence (59) down.
2. Take the fence (60) off.
