FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on
the tool.
Adjusting the depth of cut
6 cutting depths can be preset according to the size of
biscuit to be used or if trimming the wall or ceiling panels
as explained later. Rotate the stopper until the pointer
points to the appropriate size marked on the stopper.
Refer to the table below for the correspondence between
the sizes marked on the stopper and the biscuit size.
Fine adjustments to the cutting depth can be made by
turning the adjusting screw after loosening the hex nut.
This may become necessary after the blade has been
resharpened a few times.

To adjust the angle guide height, loosen the lock lever
down and rotate the knob until the pointer points to the
desired scale graduation marked on the angle guide.
Then tighten the lock lever up to secure the angle guide.
The scale on the angle guide indicates the distance from
the top of the workpiece to the center of the blade thick-
ness.
Fence
The angle of the fence can be adjusted between 0° and
90° (positive stops at 0°, 45° and 90°). To adjust the
angle, loosen the lock lever and tilt the fence until the
pointer points to the desired graduation on the angle
scale. Then tighten the lock lever to secure the fence.
