7. Assembly
7.1 Setting up the saw unit (Fig. 1/2)
To adjust the turntable (8), loosen the locking
handle (10) by approx. 2 turns, which frees the
turntable (8).
Turn the turntable (8) and scale pointer (11) to
the desired angular setting on the dial (12) and
lock into place with the locking handle (10).
Lightly press the machine head (4) down while at
the same time pulling the retaining pin (16) out
from the motor mounting; this causes the saw to
move down to the lower working position.
Swing the machine head (4) up until the retaining
hook latches into place.
The clamping device (19) and the workpiece
support (20) can be fastened on both the right
and left sides of the base plate (9).
By loosening the tightening screw (13), the
machine head (4) can be angled to the left up to
45°.
7.2 Making 90° crosscuts with turntable at 0°
(Fig. 1/3)
For cutting widths up to 140 mm it is possible to fix
the saw's drag function with the knurled screw (14) in
rear position. If the cutting width exceeds 140 mm
you must ensure that the knurled screw (14) is
slackened and that the machine head (4) can be
moved.
Bring the machine head (4) to its upper position.
Push the machine head (4) back by its handle (2)
and affix in this position if necessary (depending
on the cutting width).
Place the piece of wood to be cut against the
stop rail (7) and on the turntable (8).
Secure the workpiece in position with the
clamping device (19) on the base plate (9) to
prevent the workpiece from moving during the
cutting process.
Turn the release lever (1) to the right to release
the machine head (4).
Press the locking button (26) with your thumb
and push the ON/OFF switch (3) to start the
motor. Using the handle (2), push downward all
the way through the work-piece with uniform and
light pressure.
After the cutting process is finished, bring the
machine head back to its upper (home) position
and release the ON/OFF button (3).
Caution! The resetting springs in the machine
automatically raise the machine head. Do not
simply let go of the handle (2) after cutting, but
allow the machine head to slowly lift up by
applying slight counterpressure.

7.3 Precision adjustment of the stop for crosscut
90° (Fig. 4/5)
Lower the machine head (4) and fasten in place
with the safety pin (16).
Slacken the tightening screw (13).
Place the angular stop (a) between the blade (5)
and the turntable (8).
Slacken the counternut and adjust the adjustment
screw (21) until the angle between the blade (5)
and the turntable (8) equals 90°.
Retighten the counternut to secure this setting.
Finally, check the position of the angle indicator.
If necessary, release the pointer with a crosstip
screwdriver, move to the 0° position of the angle
scale (15) and retighten the holding screw.
7.4 Making 90° crosscuts with turntable at 0° -
45° (Fig. 6)
With the BKG 1800 your can make right and left
angular cuts from 0° - 45° to the stop rail.
Use the handle (2) to set the turntable (8) to the
desired angle i.e. the scale pointer (11) on the
turntable must coincide with the desired angular
setting (12) on the stationary base plate (9).
Re-tighten the locking handle (10) to lock the
turntable (8) into place.
Cut as described under section 7.2.
7.5 Mitre cuts 0°-45° and rotary table 0° (Fig. 4/7)
The BKG 1800 can be used to make mitre cuts of 0°-
45° relative to the machine bed on the left side.
Lift the machine head (4) to its top position.
Fix the rotary table (8) in 0° position.
Undo the locking nut (13) and, holding the handle
(2), tilt the machine head (4) to the left until the
pointer (23) coincides with the required angle
dimension (15).
Re-tighten the locking nut (13) and make the cut
as described in Section 7.2.
7.6 Precision adjustment of the stop for 45° mitre
cuts (Fig. 4/8)
Lower the machine head (4) and fix with the lock
pin (16).
Fix the rotary table (8) in 0° position.
Undo the locking nut (13) and, holding the handle
(2), tilt the machine head (4) to the left by 45°
Place the 45° stop angle (b) between the saw
blade (5) and the rotary table (8).
Slacken the counter nut and adjust the setting
screw (22) until the angle between the saw (5)
