Turn the tool on without the blade making any contact

and wait until the blade attains full speed. Then rest the

base flat on the workpiece and gently move the tool

forward along the previously marked cutting line.

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.
