Preparation

Insert the batteries before putting
into operation for the first time.
Slide the battery compartment
cover 4 in the direction of the rect­angle point and open. While insert­ing the batteries, make sure that
they are properly oriented
(see Figure B).

The tool automatically switches on
after the insertion of the batteries.
All display segments appear for
about 5 seconds while the unit per­forms a self check and calibration.
Once it is completed, the tool dis­plays the “current angle”; that is,
the present angle between the legs.

When the battery indicator
stays on, it indicates that the bat­teries are running low and that
measurements can be made only
for about another 1–2 hours. If the
battery indicator starts to blink,
power is so low that measurements
are no longer possible, and the bat­teries must be replaced.

Switching On and Off

– ON: Press button 11. All seg-

ments of the angle display ap­pear briefly.

– OFF: When the tool is in the nor-

mal measuring mode, press but­ton 11 for less than 1 second.

After 3 minutes without button
actuation or angle change, the tool
switches off automatically to maxi­mize battery life.

Exiting Special Modes

A press of 11 ON/CLEAR/OFF for
less than 1 second while the tool is
in the SIMPLE MTR or COMPOUND
MTR modes (or when HOLD [mem­ory] is flashing) returns the tool to
the normal measuring mode.

Operation

Normal Measuring Mode –
Measuring the Angle of
Structure or Workpiece
(See Figure D–F)

1 Place both legs flat on the sur-

faces adjacent to the angle.

2 The “tool-interior angle” w (the

angle between the main leg 6 and
the adjustable leg 2) is measured.

3 The angle measurement in

degrees is shown in the display.

Notes:

– Contact surfaces and contact

edges must be clean. A dirty
surface will cause erroneous
measurements.

– For increased ability to see the

measurement, there are displays
on both the front and back sides
of the tool.

– When the angle between the

legs is changed, the angle mea­surement displayed is automati­cally updated.

Using the Leg Extension
(Optional Attachment)

The leg extension makes it possible
to measure convex angles when
one of the contact surface areas is
too short to accommodate the
length of the legs.

– Slide the leg extension 14 onto

the adjustable leg 2 in the direc­tion indicated by the arrow on
the extension.

Bosch Power Tools 2 609 140 572 | (8.9.08)

– The leg extension can be extend-

ed out up to 6-3/4" or 170 mm
(see Figure A).

– When the extension is used in

this way, the “tool-interior an­gle” w is displayed though it is

the “tool-exterior angle” v that
is needed (see Figure G). To

determine the “tool-exterior
angle”, subtract displayed angle
measurement from 180°
(v = 180°–w).

Examples of Leg Extension Usage

– Figure G illustrates the measure-

ment of a stairway step’s angle.

– Figure H illustrates the measure-

ment of the angle of the top of a
ventilation shaft that is to be
covered.

– Figure I illustrates the measure-

ment of a sloped window’s angle.

Transferring of Angles
(See Figure D)

The Miterfinder™ can also be used
to copy existing angles from one lo­cation to another:
1 Measure the angle to be copied

and keep the tool opened to that
angle.

2 Place the contact edges of the

tool onto the structure or work­piece and use the tool as a
straight edge to mark both legs
of the intended angle location.

Protractor

The Miterfinder™ can also be used
to position a workpiece or intended
cut line at exactly the desired angle
1 Open the tool to the desired

angle.

2 Please the tool into the intended

position of the work.

3 Use the tool as a straight edge to

mark both legs of the intended
angle location.

HOLD (Memory)

The hold memory is a single-value
memory that is useful for several
purposes:
– For storing a specific angle value

will be used repeatedly in com­pound cut calculations, such as
the common 38° crown molding
spring angle.

– For storing an angle measured in

a confined situation …
y when the display cannot be

seen when the measurement
is taken and

y when it is necessary to fold

the leg to move the tool so
that the display can be seen.
(For example, when measur­ing the angle of eaves from an
attic.)

Procedure

To store an angle in the HOLD
memory,
– Press the RECALL/HOLD button

5 for more than 1 second.

– The display and HOLD indicator g

blink twice of to confirm the suc­cessful storage of the angle.

To recall the stored angle, simply
press the RECALL/HOLD button 5
for less than 1 second. The recalled
angle then flashes in the display.

Notes:

– The tool maintains the stored

angle even after the tool is shut­off manually or automatically.

– However, if the battery power is

exhausted or when the batteries
are removed, the stored angle
will be lost and need to be re­stored after new batteries are in­stalled.

– If the HOLD button is pressed

for more than 1 second when

0.0° is the displayed angle, any
stored angle is deleted.

Determining Angles for
Simple Miter Cuts

The SIMPLE MTR feature deter­mines miter angles for miter cuts
that are made with the blade verti­cally perpendicular to the work­piece; in other words, miter cuts for
which the bevel setting is set at 0°.
Such applications include mitering
baseboard and base shoe, chair
rail, picture rails, door frames, stair­case balusters, and picture frames.

Procedure
1 Measure the joint’s angle by

placing the legs flat against the
surfaces adjacent to the angle.

2 Determine the miter angle by

pressing the SIMPLE MTR but­ton for more than 1 second.

3 The necessary miter angle is

displayed and “MTR” appears in
the display.

4 Set the miter angle on the saw,

taking care to properly orient
the workpiece according the
saw’s instruction manual.

5 Return to the normal mea-

suring mode by pressing the
ON/CLEAR/OFF button for less
than 1 second.

Notes:

– To exit the SIMPLE MTR mode,

press ON/CLEAR/OFF for less
than 1 second.

– The DAF220 Miterfinder™ pro-

vides miter angle values for saws
with miter scales that have 0° as
the setting for a perpendicular
cut. When making miter cuts us­ing tools that have 90° as the set­ting for perpendicular cuts (such
as many table saw miter gauges),
the MTR angle needs to be sub­tracted from 90° to calculate the
setting needed on such saws:

90° – MTR = correct miter set­ting for saws with 90° perpen­dicularity setting.

– Always observe all of your saw’s

instructions, including those for
positioning and clamping the
work pie ce. In s ome ca ses, it may
not be possible to set the re­quired angles on a particular
saw or type of saw, and an alter­native means of performing the
cut will need to be used. For ex­tremely acute (sharp) angles, it
may be necessary to make the
cut using a taper jig with a table
saw or circular saw.

Determining Angles for
Compound Miter Cuts

The Miterfinder™ can be used to
easily determine the miter and
bevel angles needed to create pre­cision joints at compound angles.
This is particularly useful when cut­ting crown molding laid flat on a
compound miter saw.

Procedure

1) Set the Spring Angle

The spring angle is the angle be­tween the back of the crown mold­ing and the wall.

There are two ways to set the
spring angle:

A) Open The Tool to The Spring

Angle

– Open the legs to crown mold-

ing’s spring angle (typically 38°
or 45°).*

– The entry is confirmed by the

appearance of “SPR” in the dis­play.

OR

B) Recall A Spring Angle Stored

in “HOLD” (Recommended for
easy repeated use.)

See “HOLD (Memory)” section

– Press the RECALL/HOLD for less

than 1 second to recall the
stored angle.

– Set this value as the spring angle

by pressing the COMPOUND
MTR button.

– The entry is confirmed by the ap-

pearance of “SPR” in the display.

– The main display reverts to

showing the angle to which the
tool is opened.

2) Measure the Corner Angle

– Place the legs flat on the walls.

– Store the corner angle by again

pressing the COMPOUND MTR
button.

– The entry is confirmed by the ap-

pearance of “CNR” in the display.

3) Determine the Miter Angle &
Bevel Angles

– Press the COMPOUND MTR

button again to display the nec­essary miter angle

– “MTR” appears in the display.

4) Set the Miter and Bevel Angles
on the Saw, taking care to prop-

erly orient the workpiece ac­cording the saw’s instruction
manual.

5) Return to the Normal Measur­ing Mode

– Press the ON/CLEAR/OFF but-

ton (for less than 1 second) to
exit the Compound MTR mode
and return to the normal mea­suring mode.

– The current angle appears in the

main display.

Notes:

– When dealing with compound

angle situations other than the
cutting of crown molding laid
flat, one of the measured struc­ture or workpiece angles should
be treated as though it were a
spring angle (SPR) and the other
as the corner angle (CNR).

– If a measured angle is outside

the range of 0° to 180°, “– – – –”
appears in the display for about
2 seconds, then the tool reverts
to the normal measuring mode.

– To exit the COMPOUND MTR

mode, press ON/CLEAR/OFF for
less than 1 second.

How to Determine The Spring
Angle of A Crown Molding

1 Place the crown molding on the

Miterfinder™ as shown in Figure.
Note that the back of the crown
molding must be placed on the
top of the tool’s main leg 6 and
that the lower edge of the crown
molding must face the adjustable
leg 2.

2 Open the adjustable leg to the

angle that exactly matches the
lower edge of the crown mold­ing.

3 Subtract displayed angle mea-

surement from 180° to deter­mine the spring angle.

Notes:

– The lower edge is typically the

more-detailed edge of the crown
molding.

– The most common crown mold-

ing spring angles are 38° and 45°.
