 Assemble the worktable properly before mounting the
power tool. Perfect assembly is important in order to pre-
vent the risk of collapsing.
– Mount the power tool in transport position on the saw
stand.

Dust/Chip Extraction

Dusts from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dusts can cause allergic
reactions and/or lead to respiratory infections 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 contain-
ing asbestos may only be worked by specialists.
– Always use dust extraction.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.
The dust/chip extraction can be blocked by dust, chips or
workpiece fragments.
– Switch the machine off and pull the mains plug from the
socket outlet.
– Wait until the saw blade has come to a complete stop.
– Determine the cause of the blockage and correct it.
Integrated Dust Extraction (see figure C)
– Mount extraction adapter 45 firmly onto chip ejector 46.
– Mount dust bag 1 firmly onto extraction adapter 45.
During sawing, the dust bag and the extraction adapter may
never come in contact with moving tool components.
Always empty the dust bag in good time.
External Dust Extraction
For dust extraction, you can also connect the extraction
adapter 45 to a vacuum hose (Ø 32 mm).
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Changing the Tool (see figures D1–D3)
 Before any work on the machine itself, pull the mains
plug.
 When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
Use only saw blades whose maximum permitted speed is
higher than the no-load speed of the power tool.
Use only saw blades that correspond with the characteristic
data given in these operation instructions and that are tested
and marked in accordance with EN 847-1.
Use only saw blades recommended by the tool manufacturer,
and suitable for sawing the materials to be cut. This prevents
overheating of the saw teeth during sawing.

Removing the Saw Blade
– Bring the power tool into the working position.
– Loosen the screws 49 and 50 with the provided cross-
head screwdriver 33.
Do not completely unscrew the screws.
– Push the locking lever 41 and swing the retracting blade
guard 8 to the rear to the stop.
– Turn hexagon bolt 49 with the supplied socket spanner 33
and at the same time press the spindle lock 40 until it en-
gages.

– Remove the saw blade 7.
Mounting the Saw Blade
If required, clean all parts to be mounted prior to assembly.
– Place the new saw blade onto the interior clamping flange
52.
 Take care during the mounting that the cutting direc-
tion of the teeth (direction of the arrow on the saw
blade) agrees with the direction of the arrow on the re-
tracting blade guard!
– Mount the clamping flange 51, the washer 50 and the hex-
agon bolt 49.
Press spindle lock 40 until it engages and tighten hexagon
bolt 49 with the supplied socket spanner 33 in anticlock-
wise direction with a tightening torque of approx.
15–23 Nm.
– Push the locking lever 41 and guide the retracting blade
guard 8 down again.
– Retighten the screws 49 and 50.
Operation
 Before any work on the machine itself, pull the mains
plug.
Transport Safety (see figure E)
The transport safety-lock 26 enables easier handling of the
machine when transporting to various working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 5 down a little in order to
relieve the transport safety-lock 26.
– Pull the transport safety-lock 26 all the way outward and
turn it by 90°. Allow the transport safety-lock to engage in
this position.
– Guide the tool arm slowly upward.
Securing the Machine (Transport Position)
– Loosen the locking screw 29 if tightened. Pull the tool arm
completely to the front and tighten the locking screw
again.
– Screw the depth stop 59 completely to the top. (see "Ad-
justing the Depth Stop", page 33).
– To lock the saw table 16, tighten the locking knob 12.
– Pull the transport safety-lock 26 all the way outward and
turn it by 90°. Allow the transport safety-lock to engage in
this position.
