A
Danger!
For grooving the blade guard
must be removed. By doing so the
saw blade is accessible from the top!
Reinstall the blade guard as soon as
you have finished grooving!
1. Remove the blade guard.
2. Set riving knife to the lowest position
(see "Installation and Transport").
3. Set cutting height (= groove depth).
To measure the cutting height put a
steel rule against the saw blade.
4. If necessary install the rip fence with
the lock screw pointing towards you,
the operator.
5. Set the rip fence to the distance the
groove is to have from the work
piece's edge. Check to see that the
rip fence is parallel with the blade.
6. Start saw.
A
Risk of kickback!
During the groove cutting
operation it is especially important no
lateral pressure is applied to the saw
blade. Otherwise the work piece may
be kicked up abruptly!
7. Push work piece in a steady motion
towards the rear and cut the groove
in a single pass.
8. Turn machine OFF and reinstall the
blade guard if no further cutting will
be done immediately afterwards.
A
Danger!
Prior to all servicing:
1. turn the machine OFF,
2. unplug,
3. wait until the machine has come
to a complete stop.
−
Repair and maintenance work other
than described in this section should
only be carried out by qualified spe-
cialists.
−
Replace defective parts, especially
of safety devices, only with OEM
replacement parts. Parts not tested
and approved by the manufacturer
can cause unforeseen damage.
−
Check that all safety devices are
operational again after each service.
9.1 Saw Blade Change
A
Danger!
•
Right after cutting the saw blade
may be very hot – burning haz-
ard! Let a hot saw blade cool
down. Do not clean a hot saw
blade with any combustible liq-
uids.
•
Risk of injury, even with the saw
blade at standstill. When loosen-
ing and tightening the arbor bolt,
the retractable blade guard must
encompass the saw blade. Wear
gloves when changing blades.
1. Lower sawhead and lock for trans-
port.
2. Set the track arm holder to 0° (verti-
cal) and tighten the bevel tilt lock
screw.
3. Loosen the nut holding the blade
guard and take the blade guard off.
4. Loosen the depth of cut lock screws,
raise upper saw table fully and take
it off.
5. Swing sawhead up.
6. To keep the saw blade from turning,
pull the saw blade lock
(53) forward.
At the same time slowly turn the saw
blade by hand, until the saw blade
lock engages.
7. Loosen the arbor bolt (54) on the
saw spindle (left-handed thread!).
8. Remove arbor bolt (54) and outer
blade flange (55) from the saw spin-
dle.
9. Take saw blade (56) off the saw
spindle and lift it up to remove from
the machine.
10. Remove the inner blade flange (57)
from the saw spindle.
11. Clean clamping surfaces of:
−
saw spindle,
−
inner blade flange,
−
saw blade,
−
outer blade flange,
−
arbor bolt.
A
Danger!
Do not use any cleaning
agents (e.g. to remove resin residue)
which would tend to corrode the light
metal components of the machine;
the stability of the saw could be com-
promised.
12. Put the inner blade flange (57) on
the saw spindle.
A
Danger!
Fit the inner blade flange cor-
rectly! Otherwise the saw might jam,
or the saw blade might work itself
loose! The inner blade flange is in the
correct position when the chamfered
collar (58) points to the right and the
spring ring groove points to the left.
13. Mount the new saw blade (56) – and
pay attention to the direction (the
arrow on the saw blade must point
in the same direction as the arrow
on the blade guard)!
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 the saw blade using only
OEM parts.
−
Do not use loose-fitting reduction
rings; the saw blade could work
itself loose.
−
Saw blades have to be mounted
in such way that they do not wob-
ble, run out of balance and can
not work themselve loose during
operation.
