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 but-

ton 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 mea-

surement displayed is automati-

cally 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 direc-

tion indicated by the arrow on

the extension.

– 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 an-

gle” 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 work-

piece 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 com-

pound 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 suc-

cessful 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 shut-

off 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 re-

stored after new batteries are in-

stalled. – 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 but-

ton 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 us-

ing tools that have 90° as the set-

ting for perpendicular cuts (such

as many table saw miter gauges),

the MTR angle needs to be sub-

tracted from 90° to calculate the

setting needed on such saws:

90° – MTR = correct miter set-

ting for saws with 90° perpen-

dicularity setting.

– Always observe all of your saw’s

instructions, including those for

positioning and clamping the

w or kp iec e. I n s o me ca ses , it may

not be possible to set the re-

quired angles on a particular

saw or type of saw, and an alter-

native means of performing the

cut will need to be used. For ex-

tremely 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°).*

– Set this value as the spring angle

by pressing the COMPOUND

MTR button. – The entry is confirmed by the

appearance of “SPR” in the dis-

play. 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.

4) Set the Miter and Bevel Angles

on the Saw, taking care to prop-

erly orient the workpiece ac-

cording the saw’s instruction

manual.

5) Return to the Normal Measur-

ing Mode

– Press the ON/CLEAR/OFF but-

ton (for less than 1 second) to

exit the Compound MTR mode

and return to the normal mea-

suring 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 struc-

ture 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 mold-

ing. 3 Subtract displayed angle mea-

surement from 180° to deter-

mine 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°.

Troubleshooting

Issue Remedy

Noise is coming from area between the tool’s legs

MTR value doesn’t correspond to the miter scale on a particular saw.

It is not clear as to how to position the workpiece on the saw.

Battery symbol is flashing

“– – – –” appears in display

No action typically required. The sound is from the motor is used to measure the angle between the legs.

The Miterfinder provides miter angle values for saws with miter scales that have 0° as the setting for a perpendicular cut.

When making miter cuts on tools that have 90° as the perpendicular cut setting, the MTR angle provide by the Miterfinder needs to be subtracted from 90°.

Follow the saw’s instructions regarding the positioning and clamping of the workpiece.

Replace batteries

The tool is not designed to perform the desired operation
