FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting depth of cut (Fig. 1)
To adjust the shoe, turn the thumb screw to loosen. Slide
the shoe to the desired position and tighten the thumb
screw securely. Check for the proper clearance beneath
the workpiece before cutting so that the bit will not strike
a hard surface such as the floor, workbench, etc.
Switch action (Fig. 2)
CAUTION:
• Before plugging in the tool, always check to see that
the switch lever actuates properly and returns to the
"OFF" position.
To start the tool, move the switch lever to the "ON" posi-
tion.
To stop the tool, move the switch lever to the "OFF" posi-
tion.
This can be done in the forward area of the switch lever
or by bumping off the rear area of the switch lever.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing bit (Fig. 3)
CAUTION:
• Do not tighten the collet nut without inserting a bit, or
the collet cone will break.
• When using the bit with 6.35 mm shank diameter, first
remove the adapter from the collet cone, then install
the bit.
To install the bit, insert the bit all the way into the collet
cone.
Press the shaft lock to keep the shaft stationary and use
the wrench to tighten the collet nut securely.
To remove the bit, follow the installation procedure in
reverse.
Changing the collet cone (Fig. 4)
CAUTION:
• Use the correct size collet cone and adapter for the bit
which you intended to use.
• Do not tighten the collet nut without inserting a bit, or
the collet cone will break.
To change the collet cone, loosen the collet nut and
remove. Remove installed collet cone and adapter and
replace with desired collet cone and adapter. Reinstall
collet nut.

OPERATION

CAUTION:
• Avoid forcing the bit to bend or twist. It may snap.
• Before turning the tool on, make sure the bit and collet
nut are securely tightened.
Hold the tool secure with the bit pointing in a safe direc-
tion not contacting any surface and slide the switch to the
"ON" position. Wait until the tool attains full speed.
When starting the multipurpose bit into the material, hold
the tool at approximately a 45 degree angle with the edge
of the shoe base contacting the material. (Fig. 5)
Carefully bring the tool to a straight position so the shoe
base is in full contact with the material. (Fig. 6)
When inserting the drywall guide bit into the drywall,
carefully insert the bit straight until the shoe base is in full
contact with the material. (Fig. 7)
Move the tool slowly with a constant pressure in a clock-
wise direction to make the cut.
When cutting straight line, clamp a straight board firmly
to the material and use it as a guide. Move the tool in the
direction of the arrow with the shoe base flush with the
side of the guide board. (Fig. 8)
When the cut is complete, turn the tool off and wait for
the bit to stop rotating and then carefully remove it from
the material.
NOTE:
1. When using this tool, the rotating action causes the
tool to pull. The less pressure applied to the tool
causes less pull and provides a more accurate cut.
Excessive pressure or fast cutting can cause the bit
to dull or break premature.
2. When cutting drywall around outlet boxes, cut in a
counterclockwise direction for ease of cut.
3. The standard bit included with this tool is for cutting
drywall only. When cutting materials other than dry-
wall, do not use the standard drywall guide bit.
Circular guide
Circular cutting diameters: 10 cm – 34 cm
Installing circular guide
Release the thumb screw which serves to secure the
shoe. (Fig. 9)
Align the projections in the circular guide with the
grooves in the shoe, and secure the shoe and circular
guide using the thumb screw. (Fig. 10)
To adjust the cutting depth, proceed first by loosening the
thumb screw and then by sliding the shoe and circular
guide together. After completion of the adjustment,
tighten the thumb screw securely. (Fig. 11)
Operation
Loosen the knob, and adjust its position in accordance
with the size of the circle to be cut. (The hole dimensions
to be cut are indicated on the side of the circular guide as
a general guideline.) After completion of the adjustment,
tighten the knob securely. (Fig. 12)
Insert the end of the knob into the centre of the circle to
be cut, and proceed to cut in a clockwise direction.

Vacuum cover
Cleaner operations can be performed by connecting the
cutout tool to Makita vacuum cleaner or dust collector.
