securely on the workpiece. (Note: auxiliary tools
may be needed depending on the contour of the
workpiece, e.g. curved contours).
• Never machine workpieces that are to small to
clamp properly.
• Make sure that the saw blade cannot pull the
workpiece backwards into the gap between the
saw blade and the stop ruler. Users are at par-
ticular risk when performing horizontal mitre
cuts.
• Reinforce very thin workpieces (24.2) by sawing
them together with an additional strip (24.2).
Very thin workpieces can wobble or break when
being cut.
Procedure
– Place the workpiece on the saw table and push
it against the stop ruler.
– Release the lever (17.1) for the workpiece
clamp.
– Turn the workpiece clamp until the holding rod
(17.2) is over the workpiece.
– Lower the holding clamp onto the workpiece.
– Close the clamping lever (17.1).
8.2 Speed control
You can regulate the rotational speed steplessly
between 1400 and 3400 rpm using the adjusting
wheel (2.2). This enables you to optimise the cut-
ting speed to suit the respective material.
Recommended position of the adjusting wheel
Wood
3 - 6
Plastic 3 - 5
Fibreboard materials 1 - 3
Aluminium and non-ferrous profi les 3 - 6
8.3 Cutting without guiding action
– Make the required adjustments to the ma-
chine.
– Secure the workpiece.
– Slide the saw unit backwards up to the fence
(towards the workpiece stop) and close the
rotary knob (1.5) for clamping the guide fi xture,
or secure the saw unit in the special cutting
position (KS 120 EB only).
– Switch on the machine.
– Hold the saw unit by the handle (1.1), guide
slowly downwards and cut through the work-
piece at an even rate of advance.
– Switch off the machine and wait until the saw
blade stops completely.
– Swivel the saw unit upwards again.
8.4 Cutting with guiding action
– Make the required adjustments to the ma-
chine.
– Secure the workpiece.
– Draw the saw unit forwards along the guide
rods.
– Switch on the machine.
– Hold the saw unit by the handle (1.1) and guide
slowly downwards.
– Push the saw unit backwards at an even rate of
advance and cut the workpiece.
– Switch off the machine.
– Wait until the saw blade stops completely and
then swivel the saw unit upwards.
8.5 Bevel (KS 120 EB only)
You can use the bevel to record any angle (e.g.
between two walls) and transfer the dissecting
angle to the circular cross-cut saw. Available as
accessories.
Interior angle
– Open the clamp (18.2).
– Place the bevel with the two legs (18.1) against
the interior sides of the corner.
– Close the clamp (18.2).
– Place the bevel with one leg on a stop ruler at-
tached to the circular cross-cut saw.
– To set the dissecting angle (horizontal mitre
angle), swivel the saw unit until the laser beam
is congruent with the line (19.1) on the bevel.
Exterior angle
– Open the clamp (18.3).
– Slide the aluminium profi le (18.4) on both legs
forwards.
– Place the bevel with the two legs (18.4) against
exterior sides of the corner.
– Close the clamp (18.3).
– Slide back the aluminium profi le on both legs.
– Place the bevel with one leg on a stop ruler at-
tached to the circular cross-cut saw.
– To set the dissecting angle (horizontal mitre
angle), swivel the saw unit until the laser beam
is congruent with the line (19.1) on the bevel.
9 Service and maintenance
Always pull the plug out of the socket
before performing any type of work on
the machine!
All maintenance and repair work which
requires the motor housing to be opened,
must only be carried out by an authorised
service workshop.
Damaged safety devices and parts should
be repaired or replaced by an authorised
service centre unless otherwise specifi ed
in the operating instructions.
