Tips and tricks

Before making a cut: make a trial
•
cut on appropriate waste pieces.
Always lay the workpiece on the
•
saw table such that it cannot tip
over or wobble (e.g. place a curved
board with the convex side up).
• For long workpieces: use suitable
workpiece supports, for example
roller support or extension table
(see 'Available Accessories').
Keep surfaces of the table top and
•
table extension clean – in particular,
remove resin residue with a suitable
cleaning and maintenance spray
(optional accessory).

Care and maintenance

A
Danger!
Unplug before servicing.
– Repair and maintenance work oth-
er than described in this section
should only be carried out by quali-
fied specialists.
– Damaged parts, particularly safety
devices, must only be replaced with
genuine parts. Parts which have not
been tested and released by the
manufacturer can lead to unfore-
seen damage.
– Check that all safety devices are
operational again after each ser-
vice.

Changing the saw blade

A
Danger!
Directly after cutting the saw blade
can be very hot – burn hazard! Let a
hot saw blade cool down.
Do not clean the saw blade with
combustible liquids.
Risk of injury, even with the blade at
standstill. Wear gloves when chang-
ing blades.
When fitting a saw blade, observe
the direction of rotation!

3. Carefully take the outer blade collar
(74) off the saw spindle. Hold the
saw blade while doing so.
4. Remove the saw blade from the
saw spindle.
5. Clean the saw blade, inner blade
collar (73) and outer blade collar
(74).
A
Danger!
Do not use any cleaning agents (e.g.
to remove resin residue) which
could attack the light metal compo-
nents; otherwise the strength of the
part could be lowered.
6. Put on a fresh saw blade (observe
direction of rotation!).
A
Danger!
Use only saw blades meeting the re-
quirements of EN 847-1 (see "Tech-
nical Specifications") – if unsuitable
or damaged saw blades parts are
used, parts can be ejected due to
centrifugal force in an explosive-
type manner.
Do not use:
– saw blades with maximum speed
ratings lower than the saw spin-
dle speed (see 'Technical Data');
– saw blades made of high-
strength steel (HSS or HS);
– saw blades with visible damage
or deformations;
– cut-off wheel blades.
A
Danger!
– Only install saw blade with genu-
ine parts.
– Do not use any reduction rings;
otherwise the saw blade could
loosen.
