registration surface. A flat blade screwdriver can be used to

rotate the pins as shown in FigureK.

Bottom Registration Surface

For certain applications, you will want to use the bottom

surface of the biscuit joiner for alignment. When using the

bottom registration surface, the adjustable fence should be

set to 0° and the height setting is unimportant. This surface

is used primarily when making ‘T’ joints (see applications

section). The distance between the centerline of the blade

and the bottom registration surface is fixed at 3/8" (9.5mm)

which allows centering on 3/4" (19mm) thick stock. The

three grooves on the bottom registration surface indicate the

centerline (or the deepest point) of the biscuit cut and the

approximate width of a #20 biscuit so that you’ll know where

the edge of the blade is and can prevent breakthrough. To

avoid breaking through the workpiece, align the shoe so

that neither outside mark extends beyond the end of the

workpiece. If either side does, there is a good chance that the

blade will break through the end or your workpiece and ruin

yourwork.

Dust Extraction (Fig. L–N)

There are three options provided for collecting dust from

your biscuit joiner as describedbelow.



WARNING: Risk of dust inhalation.To reduce the risk of

personal injury, ALWAYS wear an approved dustmask.

Adjustable Direction Elbow Attachment (Fig.L)

The adjustable direction elbow attachement

16

inserts

into the dust exhaust port on the right side at the rear of

the base assembly and clicks into place. To remove, pull

out firmly. The directional elbow rotates easily to aim the

dust in the most convenient direction suitable for the

particularapplication.

Dust Adaptor (SeeFigure M1)

This straight attachment

15

, when inserted as described

above, allows the use of several common sizes of vacuum

hose to be attached for direct vacuum pick‑up of thedust.

AirLock Compatible Dust Adapter (Fig.M2)

A dust extraction port

5

is supplied with yourtool.

The dust extraction port allows you to connect the tool to an

external dust extractor, either using the AirLock™ system, or a

standard 35mm dust extractorfitment.



WARNING: ALWAYS use a vacuum extractor designed

in compliance with the applicable directives regarding

dust emission when sawing wood.Vacuum hoses of

most common vacuum cleaners will fit directly into the

dust extractionoutlet.

Your tool is compatible with the DEWALT AirLock™

connection system. The AirLock™ allows for a fast, secure

connection between the AirLock™ connector

19

and the

straight attachment

15

1. Remove thebattery.

2. Ensure the collar on the AirLock™ connector is in the

unlock position. (Refer to FigureM2.) Align notches

20

on collar and AirLock™ connector as shown for unlock

and lockpositions.

centerline of the blade (see Figure I). The adjustable

angle feature allows a full range of settings from 0° to

90as well as a reverse 45° bevel which allows outside

registration on miter joints. (See Applications section

under Miter Joints, Figure BB.)

b. The height adjustment is accomplished by first

loosening the lock knob

9

on the right side of the

fence and then rotating the knurled adjustment

knob

4

until the desired height is reached (see

FigureH).

c. The rack and pinion system of the fence automatically

aligns the fence parallel to the blade, with the lock

knob locking it in position. The vertical scale and

pointer located directly under the lock knob can

be used to assist in setting this height. The scale

readings indicate distance from the blade centerline

to the fence surface when the fence is set at 90°

(see FigureI). The fence angle can be set simply by

loosening the lock knob on the left side of the tool,

aligning the protractor scale with the pointer and

tightening the lockknob.

Plunge Depth Adjustment (Fig. E, J)

The depth of cut can be set to match the dimensions of the

particular size biscuit you will be using. The numbers on the

depth adjustment knob

8

(0,10, 20, M) coincide with the

three sizes of biscuits shown in Figure E. The letter M stands

for the maximum depth capacity of the tool which is 25/32"

(20mm). This depth is obtainable only with a new blade and

by backing out the fine adjustment screw (see nextsection).

NOTE: The M setting has been provided for future use and

will not be necessary for most biscuiting operations. To select

a depth, align the appropriate number with the red arrow

scribed in the tool’s gear box, as shown in Figure J. Rotate

the depth adjustment knob to the desired position and it will

“click” into place.

Fine Depth Adjustment (Fig. K)

You may encounter situations where you want to leave a

little looseness in your joint so that you can move it slightly

before the glue sets up. For these instances a fine depth

adjustment has been provided. To adjust, you must first raise

the adjustable fence

6

to its uppermost position. Then insert

the T20 Torx wrench provided into the opening. Turn the

depth adjustment screw

21

clockwise for less depth and

counterclockwise for increased depth. Each full turn causes

a change in depth of 0.04" (1mm). Always check the depth

adjustment by first making test cuts in scrapwood.

Anti-Slippage Pins (Fig. K)

Biscuit joiners tend to slide to the left with respect to

the workpiece when making a cut. This tendency is

increased with a dull blade or when plunging very rapidly.

Anti‑slippage pins

7

have been provided to reduce this

tendency and are located on the front registration surface

on either side of the blade opening slot. When making

some joints, you may wish to retract the anti‑slippage pins

so as not to scratch your workpiece in a visible area. For this

purpose, simply rotate the anti‑slippage pins approximately

1/6 of a turn and they will retract back behind the front
