blade juts out under the workpiece. See illustration
on page 3.
6.3 Slanting saw blade for diagonal cuts
Loosen the locking screws (1). Tilt the motor part
against the guide plate (15). Read the angle which
has been set from the scale (2). Tighten the locking
screws again.
6.4 Correcting the saw disc angle
If, at 0°, the saw blade is not at right angles to the
guide plate: use the adjustment screw (8) to correct
the saw blade angle.
6.5 Extractor connection piece
Sawdust extraction
To extract the sawdust, connect a suitable
extraction unit with suction hose to the extraction
adapter (3).
7. Use
7.1 The machine's multifunctional
monitoring system
If the machine switches off automatically, the
machine electronics have activated automatic
protection mode. A warning signal sounds
(continuous beeping). The beeping stops after a
maximum of 30 seconds or when the trigger switch
(5) is released.
In spite of this protective function, overloading
is still possible with certain applications and
can result in damage to the machine.
Causes and remedies:
1. Battery pack almost flat (the electronics
prevent the battery pack from discharging totally
and avoid irreparable damage).
If one LED (20) is flashing, the battery pack is
almost flat. If necessary, press the button (21)
and check the LEDs (20) to see the charge level.
If the battery pack is almost flat, it must be
recharged.
2. Long continuous overloading of the machine will
activate the temperature cut-out.
The machine continues to run with reduced
performance until the temperature is back to
normal.
In case of excessive overheating, the machine
will switch off completely.
Leave the machine or battery pack to cool.
Note: If the battery pack feels very warm, the
pack will cool more quickly in your "AIR
COOLED" charger.
Note: The machine will cool more quickly if you
operate it at idling speed.
3. If the current is too high (for example, if the
machine seizes continuously for long periods),
the machine switches off.
Switch off the machine at the trigger switch (5).
Then continue working as normal (in this case,
read in particular the safety instructions in
14
Chapter 4...Kickback... in addition to all other
safety instructions). Try to prevent the machine
from seizing.
7.2 Switching on and off
Switching on: Push the locking button (6) forwards
and hold, then actuate the trigger (5) .
Switching off: Release the trigger switch (5).
7.3 Working Directions
Do not switch the machine on or off while the
saw blade is touching the workpiece.
Let the saw blade reach its full speed before
making a cut.
When the hand-held circular saw is added, the
movable guard is swung backwards by the
workpiece.
When sawing, never remove the machine
from the material with the saw blade turning.
Allow the saw blade to come to a standstill.
If the saw blade blocks, turn the machine off
immediately.
Do not set the machine down until the saw
blade has come to a standstill.
Sawing along a straight line: the cutting indicator
is used here (11). The left notch (marked 0°)
indicates the direction of the cut if the saw blade is
held vertically. The right notch (marked 45°)
indicates the direction of the cut if the saw blade is
held at 45°.
Sawing along a rail secured on the workpiece:
In order to achieve an exact cutting edge, you can
attach a rail to the workpiece and then guide the
hand-held circular saw by means of the guide plate
along this rail.
Sawing with parallel guide:
For cuts parallel to a straight edge. The parallel
guide (12) can be inserted from either side into the
support provided for it. Tighten the locking screw
(10). It is best to calculate the exact cut width by
making a test cut.
Sawing with guide rail 6.31213:
For dead straight, tear-free cutting edges with
millimetre precision. The anti-slip coating keeps the
surface safe and protects the workpiece against
scratches. For guide rail 6.31213, see chapter on
Accessories.
Battery pack heat generation:
Under extremely hard application conditions (e.g.
sawing thick wooden planks), the heavy load can
cause the battery pack to heat (> 60 °C). To
conserve the battery pack, allow it to cool down
before continuing work.

8. Maintenance

Changing saw blades
The saw blade must be stationary.
Remove battery pack from machine.
