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.

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 (61) on –

the two flanks must fit over the flats

of the saw spindle!

9. Screw on the arbor bolt (60) (left-

handed thread!) and tighten with the

Allen key fingertight.

To arrest the saw blade, use the

saw blade lock (59).

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.

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 (66):

Loosen the screw (67) and detach

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.

3. Replace the plastic cover (66) and

secure with the screw.

9.3 Kerf plate replacement

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!

1. Swing the hinged fence (68) down.

2. Take the fence (69) off.

3. Lever the table insert (70) up with a

screwdriver. Doing so will damage

the table insert; it can not be used

again.

4. Fit new table insert and let engage.

5. Reinstall the fence (69).

6. Swing the hinged fence up (70) and

secure it.

9.4 Adjustments

Fence adjustment

1. Swing the hinged fence down.

2. Loosen the fastening screws (71) of

the fence.

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

1. Adjust the indicator's (73) position

by means of the screw (72), until the

value indicated coincides with the

rotating table's positive stop.

Note:

The rotating table engages at

positive stops at the 0°, 15°, 22.5°, 30°,

45°, and 60° position.

Bevel tilt positive stop adjustment

1. Lock the track arm holder (74) in the

0° position.
