6. DUST EXTRACTION

There are two options provided for

collecting dust from your plate joiner as

described below.

A. Dust Adaptor (See Figure 10)

This attachment, 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.

B. Dust Bag (See Figure 11)

The dust bag provided fits snugly

over the dust adaptor described

above. To empty the bag, open the

zipper underneath and dump

dust out.

NOTE: When the bag becomes full, the

dust will back-up into the adaptor and the

exhaust port on the right rear of the tool.

To clean out, turn off and unplug the tool

and remove packed dust. The bag will

hold the dust generated from

approximately 70 to 100 #20 biscuit cuts

before filling up.

GENERALOPERATION

Plate joiners are primarily used for making

cabinetry and furniture, joining millwork or

other similar applications where a strong,

accurate joint is required in wood or

wood by-products. There are literally

hundreds of variations of joints that can

be made with your Plate Joiner. We will

limit our discussion to six basic joints (see

application section) that can be used to

build on and adapt to your own applications.

The following are some basic set-up steps

that will apply to all biscuit joints.

1. BISCUIT SIZE SELECTION

As mentioned earlier, the three biscuit

sizes are #0, #10 and #20. Itis a good

rule of thumb to use the largest biscuit

size that will physically fit in the

application. Unless you are joining narrow

face or picture frames or using 1/2" or

thinner stock, you will find the #20 biscuit

size to suit most applications. After

selecting the biscuit size, set the depth

adjustment knob to the corresponding size

(see Controls section). Also, be sure the

fine depth adjustment is correctly set by

first testing in a scrap piece. This is

extremely important as you do not want to

discover during glue-up that your biscuit

slots are not quite deep enough.

2. BISCUIT LOCATION AND LAYOUT

Generally, biscuits may be spaced and

located at your discretion. For edge joints,

a good rule of thumb is to space biscuits

every 6-10-inches on center. It is further

recommended that biscuits be placed so

that the centerline of the end biscuits is

2-3 inches from the end of the workpiece.

When joining face frames or picture

frames where the workpiece is narrow, you

may have to choose the smaller biscuit

sizes to keep from "breaking out" on the

end of the joint. Breaking out should be

avoided if possible, but if not you can

assemble the joint and trim off the

exposed biscuit tip after the glue sets (see

Figure 12). When working with material up

to 1" thick, we advise to use a single

biscuit located in the approximate center

of the material thickness. If thicker stock is

to be joined, you may choose to use 2

biscuits across the thickness for greater

strength (see Figure 13). Biscuit locations

should be marked by first positioning the

mating pieces exactly as they are to be

assembled. Next, make a mark at 90 ° to

the joint interface across both pieces at
