Bevel cutting
005931
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before tilting the base.
With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right).
Loosen the bolt on the back of the base with the hex
wrench and slide the base backwards.
Tilt the base until the desired bevel angle is obtained.
The edge of the motor housing indicates the bevel angle
by graduations. Then check the contact between the
back edge of the blade and the roller. Now tighten the
bolt to secure the base.

Cutouts
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole
005934
For internal cutouts without a lead-in cut from an
edge, pre-drill a starting hole 12 mm or more in
diameter. Insert the blade into this hole to start your
cut.
B) Plunge cutting
005935
You need not bore a starting hole or make a lead-in
cut if you carefully do as follows.
(1)
Tilt the tool up on the front edge of the base
with the blade point positioned just above the
workpiece surface.
(2)
Apply pressure to the tool so that the front
edge of the base will not move when you
switch on the tool and gently lower the back
end of the tool slowly.
(3)
As the blade pierces the workpiece, slowly
lower the base of the tool down onto the
workpiece surface.
(4)
Complete the cut in the normal manner.
Finishing edges
005936
To trim edges or make dimensional adjustments, run the
blade lightly along the cut edges.
