While inserting the saw blade, pay attention that

the back of the saw blade is positioned in the

groove of the guide roller 14.

Note: If the grooves of the saw blade holder are

not in the position shown in the figure or when

the Precision-Control guide cheeks 13 are

closed, then the saw blade 15 cannot be insert-

ed into the stroke rod 17. Briefly press the SDS

clamping lever 19 toward the side and release it

again.

f Check the tight seating of the saw blade. A

loose saw blade can fall out and lead to in-

juries.

Ejecting the Saw Blade (see figure B)

f When ejecting the saw blade, hold the ma-

chine in such a manner that no persons or

animals can be injured by the ejected saw

blade.

Press the SDS clamping lever 19 sideward to

the stop. The Precision-Control guide cheeks 13

are released and the saw blade 15 is ejected.

Dust/Chip Extraction

f Dusts from materials such as lead-containing

coatings, some wood types, minerals and

metal can be harmful to one’s health. Touch-

ing or breathing-in the dusts can cause aller-

gic reactions and/or lead to respiratory infec-

tions of the user or bystanders.

Certain dusts, such as oak or beech dust, are

considered as carcinogenic, especially in

connection with wood-treatment additives

(chromate, wood preservative). Materials

containing asbestos may only be worked by

specialists.

– Use dust extraction whenever possible.

– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your

country for the materials to be worked.

Dust Cover

Mount the dust cover 18 before connecting the

machine to the dust extraction.

Mount the dust cover 18 onto the machine in such

a manner that the holders in the centre of the

dust cover engage on the contact protector 16.

For work without dust extraction, the dust cover

18 can be removed. To remove the dust cover

18, grasp it by the side and pull it off toward the

front.

Connecting the Dust Extraction

(see figures C–E)

Mount the vacuum connection 7 into the open-

ing of the base plate 9. Make sure that the plas-

tic tip of the vacuum connection engages into

the corresponding opening on the housing as

shown in the figure.

Depending on the machine model, place a vacu-

um hose 20 (accessory) either directly onto the

vacuum connection 7 or cut off the old hose

end, screw the extraction adapter 6 (accessory)

onto the hose end and insert it directly into the

vacuum connection 7. Connect the vacuum hose

20 with a vacuum cleaner (accessory). An over-

view for the connection of various vacuum

cleaners can be found at the end of these in-

structions.

Switch the saw dust blower off when a dust ex-

traction system is connected (see “Sawdust

Blower Device”).

To enable optimum dust extraction, use the

splinter guard 21 if possible.

The vacuum cleaner must be suitable for the ma-

terial being worked.

When vacuuming dry dust that is especially det-

rimental to health or carcinogenic, use a special

vacuum cleaner.
