ENGLISH
• Before cutting a workpiece to size
make trial cuts on pieces of scrap.
• Always place a workpiece on the
saw table in such way that it cannot
tilt or rock (e.g. always place a
curved board on the table with the
convex side up).
• When working long stock use suita-
ble supports, such as roller support
or table extension (optional acces-
sories).
• Keep surfaces of saw table and
extension tables clean – in particu-
lar, remove resin residue with a suit-
able cleaning and maintenance
spray (optional accessory).
A
Danger!
Unplug before servicing.
− 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 genuine
replacement parts. Parts not tested
and approved by the equipment
manufacturer can cause unforeseen
damage.
− Check that all safety devices are
operational again after each service.
10.1 Saw blade change
A
Danger!
Directly after cutting the saw
blade can be very hot – buring haz-
ard! Let a hot saw blade cool down.
Do not clean the saw blade with com-
bustible liquids. Risk of injury, even
with the blade at standstill. Wear
gloves when changing blades.
When fitting a saw blade, observe the
direction of rotation!
1. Raise saw blade fully.
2. Remove blade guard (103).
3. Remove fixing screws of the table
insert extrusion (104) and remove it.
4. Loosen arbor bolt (105) with span-
ner (L.H. thread!). Hold outer blade
collar (106) with open jaw wrench to
counter.
5. Remove outer blade collar (106)
and saw blade from the saw spindle.
6. Clean clamping surfaces of saw
spindle and saw blade.
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.
7. Put on a fresh saw blade (observe
direction of rotation!).
A
Danger!
Use only suitable saw blades
(see "Available accessories") – when
using unsuitable or damaged blades
parts could be explosive-like hurled
from it by centrifugal force.
Do not use:
− saw blades made of high speed
steel (HSS or HS);
− saw blades with visible damage;
− 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 on outer blade collar (106) (the
inner blad collar's (107) lug must
engage in the groove of the outer
blade collar).
9. Turn arbor bolt (105) into saw spin-
dle (left-handed thread!) and tighten.
Hold outer blade collar (106) with
ring spanner to counter.
A
Danger!
− Do not extend arbor bolt tighten-
ing wrench.
− Do not tighten arbor bolt by hit-
ting the wrench.
− After the arbor bolt has been
tightened, remove all tools used
during saw blade installation!
10. Put table insert extrusion (104) in
flush with the saw table and secure
with fixing screws.
10.2 Cleaning the saw blade's
height adjustment mech-
anism
1. Raise saw blade fully and dismount
it (see "Saw blade change").
Now the spindle of the height adjust-
ment is accessible from the top.
2. Clean spindle with brush, vacuum,
or compressed air.
3. Apply a light coat of Care and Main-
tenance Spray.
4. Install saw blade and tighten arbor
bolt.
5. Install the table insert.
10.3 Saw storage
A
Danger!
Store saw so that
− it cannot be started by unauthor-
ized persons, and
− nobody can get injured.
A
Caution!
Do not store saw unprotected
outdoors or in damp environment.
10.4 Maintenance
Before switching ON
Visual check if distance saw blade – riv-
ing knife is 3...8 mm.
Visual check of power cable and power
cable plug for damage; if necessary
have damaged parts replaced by a qual-
ified electrician.
After switching OFF
Check to see if the saw blade post-runs
for more than 10 seconds; if so, have the
electronic motorbrake replaced by a
qualified electrician.
Monthly (if used daily)
Remove saw dust and chips with vac-
uum or brush; apply light coat of oil to
guide elements:
− threaded rod of height adjustment;
− swivel segments.
Every 300 hours of operation
Check all screwed joints, retighten if
necessary.
