Operation - Scheppach HM254SPX Original Bedienungsanleitung

• Loosen the lock nut (27a) and adjust the screw (27)
until the angle between the saw blade (6) and the
rotary table (14) is precisely 45°.
• Tighten the lock nut (27a) again.
• Subsequently check the position of the angle indi-
cator. If necessary, loosen the pointer (19) using a
Phillips screwdriver, set to position 45° on the angle
scale (18) and re-tighten the retaining screw.

Operation

9.1 Using the laser (fig. 18)
• To switch on: Press the ON/OFF switch laser (33)
1x. A laser line is projected onto the material you
wish to process, providing an exact guide for the cut.
• To switch off: Press again the ON/OFF switch laser
(33).
9.2 Limiting the cutting depth (cutting grooves)
(fig. 3/13)
m WARNING
Risk of kickback! When cutting grooves, it is par-
ticularly important that no lateral pressure is ex-
erted on the saw blade. Otherwise, the saw head
might suddenly kick back! Use a clamping device
when cutting grooves. Avoid lateral pressure on
the saw head.
• The cutting depth can be infinitely adjusted using the
screw (24). To do this loosen the knurled nut (24a) on
the screw (24). Turn the screw (24) in or out to set the
required cutting depth. Then re-tighten the knurled
nut (24a) on the screw (24).
• Check the setting by completing a test cut.
9.3 Serial cutting
For repeated cuts of the same length, the length stop
(37) can be opened. You can use the length stop (37)
on the right and on the left.
• Fold up the length stop (37).
• Loosen the set screw for workpiece support (9).
• Pull out the workpiece support (8).
• Set the required dimension between saw blade and
length stop (37).
• Re-tighten the set screw for workpiece support (9).
• Perform cutting as described in sections 10.4 to
10.7.
9.4 Crosscut 90° and turntable 0° (fig. 1/2/7)
In the case of cutting widths up to approx. 100 mm it is
possible to fix the traction function of the saw with the
set screw (20) in the rear position. In this position the
machine can be operated in cross cutting mode.
If the cutting width is over 100 mm then it is necessary
to ensure that the set screw (20) is loose and the ma-
chine head (4) can move.
Attention!
For 90° crosscuts, the moveable stop rail (16a) must be
fixed in the inner position.
• Open the set screw (16b) for the moveable stop rail
(16a) and push the moveable stop rail (16a) inwards.
• The moveable stop rails (16a) must be locked so that
the distance between the stop rails (16a) and the
saw blade (6) is no more than 8 mm.
• Before making the cut, check that the stop rails (16a)
and the saw blade (6) cannot collide.
• Re-tighten the set screw (16b).
• Move the machine head (4) to its upper position.
• Use the handle (1) to push back the machine head
(4) and fix it in this position if required (dependent on
the cutting width).
• Place the piece of wood to be cut at the stop rail (16)
and on the turntable (14).
• Lock the material with the clamping devices (7) on
the fixed saw table (15) to prevent the material from
moving during the cutting operation.
• Release the lock switch (3) and press the ON/OFF
switch (2) to start the motor.
• With the drag guide (21) fixed in place (21):: use
the handle (1) to move the machine head (4) stead-
ily and with light pressure downwards until the saw
blade (6) has completely cut through the work piece.
• With the drag guide (21) not fixed in place (21):
pull the machine head (4) all the way to the front.
Lower the handle (1) to the very bottom by apply-
ing steady and light downward pressure. Now push
the machine head (4) slowly and steadily to the very
back until the saw blade (6) has completely cut
through the work piece.
• When the cutting operation is completed, move the
machine head back to its upper (home) position and
release the ON/OFF button (2).
Attention! The machine executes an upward stroke
automatically due to the return spring, i.e. do not re-
lease the handle (1) after completing the cut; instead
allow the machine head to move upwards slowly
whilst applying light counter pressure.
