Dust/Chip Extraction
Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment addi-
tives (chromate, wood preservative). Materials containing as-
bestos 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 D)
– Mount the dust bag 53 onto the chip ejector 27.
During sawing, the dust bag must never come into contact
with the movable machine parts.
Always empty the dust bag in good time.
External Dust Extraction
For dust extraction, a vacuum hose (size Ø 35 mm) can also
be connected to the chip ejector 27.
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 E1–E4)
 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.
– Turn the hex socket screw 54 with the hex key 49 provided
and at the same time press the spindle lock 32 until it en-
gages.
– Hold the spindle lock 32 pressed and unscrew the hex
socket screw 54 in clockwise direction (left-hand thread!).
– Remove the clamping flange 55.
1 609 92A 27V | (8.3.16)
– Swing the retracting blade guard 8 backward and remove
the saw blade 56.
– Slowly guide the retracting blade guard downward again.
Mounting the Saw Blade
If required, clean all parts to be mounted prior to assembly.
– Swing the retracting blade guard 8 backward.
– Place the new saw blade onto the interior clamping flange
57.
 When mounting the saw blade, pay attention that the
cutting direction of the teeth (arrow direction on the
saw blade) corresponds with the direction of the arrow
on the blade guard!
– Slowly guide the retracting blade guard downward again.
– Place on the clamping flange 55 and the screw 54.
Press the spindle lock 32 until it engages and tighten the
screw turning in anticlockwise direction.
 When attaching the clamping flange, ensure that the
wide side faces the saw blade (see figure E2). The saw
blade cannot be tightened if it is installed the other way
round.
Operation
 Before any work on the machine itself, pull the mains
plug.
Transport Safety (see figure F)
The transport safety-lock 28 enables easier handling of the
machine when transporting to various working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 6 down a little in order to
relieve the transport safety-lock 28.
– Pull the transport safety-lock 28 completely outward.
– Guide the tool arm slowly upward.
Securing the Machine (Transport Position)
– Loosen the locking screw 25 if it is locking the slide device
1. Pull the tool arm fully forward and tighten the locking
screw again to lock the slide device.
– Screw adjusting screw 33 completely upward.
– To lock the saw table 21, tighten the locking knob 13.
– Swing the tool arm downward by the handle 6 until you can
press the transport safety-lock 28 completely inward.
The tool arm is now securely locked for transport.
Clamping the Workpiece (see figures G1–G3)
To ensure optimum working safety, the workpiece must al-
ways be firmly clamped.
Do not saw workpieces that are too small to clamp.
Vertical Clamping
– Insert the quick-action clamp 22 provided into one of the
holes 31 intended for this purpose.
– Press the workpiece firmly against the fences 9 and 11.
– Press the quick-release button 58 and adapt the quick-ac-
tion clamp to the workpiece.
– Afterwards, turn the locking knob 59 in clockwise direc-
tion to clamp the workpiece.
