2. Press the saw blade release lever to the side as far as
it will go. The saw blade is then released and ejected.
6.4 Dust removal using a dust removal system
-NOTE-
Use of a dust removal system reduces exposure to dust,
increases safety at the workplace by ensuring better vis-
ibility of the cutting line and helps to keep the workplace
tidy by greatly reducing the amount of dust and wood
chips in the working area.
Connect the dust removal system before working with
the tool for long periods when cutting wood or other
materials that may cause considerable dust.
The dust removal hood must be fitted when the tool is
being used with a dust removal system.
6.4.1 Connecting the system
1. Unplug the supply cord from the electric socket.
2. Fit the dust removal adaptor into the opening on the
tool.
3. Push the dust removal adaptor toward the tool from
below until it engages.
4. Connect the vacuum cleaner hose to the dust removal
adaptor.
6.4.2 Disconnecting the system
1. Unplug the supply cord from the electric socket.
2. Disconnect the vacuum cleaner hose from the dust
removal adaptor.
3. Push the dust removal adaptor downwards and pull
it out of the tool.
6.4.3 Procedure if the extraction adapter is blocked
1. Disconnect the supply cord plug from the power out-
let.
2. Clean out the extraction adapter.
3. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may
affect the power tool's operation.

6.5.2 Removing the dust removal hood
1. Unplug the supply cord from the electric socket.
2. Tilt the dust removal hood slightly and pull it away
from the tool toward the front.
6.6 Sawdust blower
The blower keeps the cutting line free of dust and chips
by directing a jet of air toward the saw blade.
6.7 Adjusting the orbital action
The four orbital action settings permit cutting perfor-
mance and quality of cut to be adjusted to suit the mate-
rial being cut.
Orbital action adjustment lever is used to set the tool to
one of the four orbital action settings.
Please observe the following recommendations:
The lower the orbital action setting, the finer and clean-
er the cut.
The optimum setting can be determined by making test
cuts.
Setting 0: No orbital action
Setting I: Low orbital action
Setting II: Medium orbital action
Setting III: High orbital action
Please refer to the information provided with the saw
blade for details of correct settings.
6.8 Adjusting the stroke rate
1. Set the stroke rate adjustment thumbwheel to a posi-
tion between 1 (slow) and 6 (fast).
Please refer to the information provided with the saw
blade for details of correct settings.

2. Remove the dust removal system adaptor.
3. Release the screw.
4. Pull the baseplate slightly toward the front of the tool.
5. Set the baseplate to the desired angle according to the
scale on the tool.
6. Tighten the screw.
6.9.2 Resetting the cutting angle
1. Unplug the supply cord from the electric socket.
2. Release the screw.
3. Return the baseplate to the 0° position.
4. Push the baseplate back to its original position (toward
the rear of the tool).
5. Tighten the screw.
6.10 Offsetting the baseplate
To facilitate sawing close to edges, the baseplate can be
