BASIC FUNCTIONS OF THIS UNIT

The 50-EXBC is designed as a blade cover and dust collection hood only. It is intended for use on 10”
(model 50-EXBC10) or 12-14” (model 50-EXBC14) tables saws, along with your existing guard, splitter or other anti­kickback device. If needed, the rear lens may be removed or slit to accommodate other safety devices.

The unit is designed to connect to any 4” dust collection system to
remove saw dust at the source directly above the blade. The
boom mount must be connected to the end of your table saw
extension table and allows the blade cover to swing out of the
way or to be completely removed as needed, in a matter of sec­onds, for blade changes and/or special cutting applications.

For ideal installation without modification a minimum distance
from the end of your extension table to the blade of 39 3/4” is
required. The telescopic inner boom can be extended to accom­modate a distance from the end of the extension table to the
blade of 67”. (Fig.1) To securely attach to the end of an extension
table, a minimum 3” apron on the end of the extension table is
required. (See Inset)

Min Distance: 39 3/4”
Max Distance: 67”

MOUNT THE HOOD ASSEMBLY TO THE INNER BOOM

1. Slide the hood assembly over the end of the inner
boom , leaving approximately 1” of the inner boom pro­truding past the mount. (Fig. 2)

2. Insert a 1/4” x 1 1/4” button head bolt through the two
holes in the band clamp section of the mount on the under­side. Thread on a 1/4” lock nut and tighten. ( Fig. 3)

INSTALL THE DUST HOSE

1. Install the dust collection hose between the hood and the
inner boom using the two supplied hose clamps , as shown
in Figure 4.

DIAGONAL BRACE ASSEMBLY

1. Spin a 1/4” hex nut onto each eyebolt. (Fig. 5)

2. Pass the eye bolts through the holes in the bent ends of the
diagonal braces and secure the eye bolts to the diagonal
braces using a lock washer and another nut. Leave approxi­mately 3/4” of the eye bolts protruding past the second nut.
(Fig. 6)

3. Fasten the brace mount angle brackets to the eyebolts using
a 1/4” x 3/4” flat head bolt, lock washer and hex nut. (See
Figure 7 for order of assembly)

Note:

Make sure the two assemblies are mirror image to each

other, (Fig. 8) and set the brace assemblies aside for now.

BOOM-MOUNT ASSEMBLY

mount channel . (Fig. 9)

2. Use the two supplied lock knobs to secure the extension
leg in the upper leg at the desired height. (Fig. 10)

BOOM-MOUNT CHANNEL INSTALLATION

1. Set the boom mount channel against the edge of your extension table, lining up the mounting pin on the
boom mount with the center of the blade . (Fig. 11)

Note: Because the slots in the boom mount channel are elongated - allowing for fine tuning later, perfect
alignment is not critical at this stage.

2. With a pencil, mark the hole placement in the table apron at the center of each mounting slot in the boom
mount channel. (Fig. 12)

Note: If your current extension table includes corner support legs, the legs may need to be removed if they
interfere with the hole placement for the boom mount channel.

Using less than 4 slots (2 at each end) is not recommended and can lead to system failure and seri­ous personal injury.

Fig.11

TOP VIEW

3. Set the boom mount channel aside and drill through-holes in the extension table apron. (Fig. 13)

4. Secure the boom mount channel to the extension table using the supplied mounting hardware in the order
shown. (Fig. 14)

Note: The supplied mounting hardware will accomodate a typical installation with a table apron of up to
3/4” thick. For thicker aprons, longer bolts (not supplied) may be required.

1. Place the boom/hood assembly on the pivot pins located on the boom mount channel (Fig. 18) and swing the
arm over the table.

2. Secure the locking pin to hold the boom in position. (Fig.19).

3. Loosen the boom clamp knob and extend the boom to position the hood assembly over the blade.
(Fig. 20)

4. Lower the hood assembly into the down position over the blade (Fig. 21) and as needed, adjust the boom
mount channel position to roughly center the hood assembly over the blade.

5. Tighten the mounting bolts and secure the boom mount channel in position on the extension table. (Fig.22)

6. If you notice any sag or if the extension table is not level with the main table, adjust the height of the support
leg (Fig. 23, ) to support the added weight of the boom/hood assembly.

7. The diagonal braces can be tightened or loosened to allow the boom assembly to be levelled as needed by
adjusting the nuts on the eye bolt. (Fig. 23)

ADJUSTMENTS

1. The resistance or balance of the swing arm assembly can be

adjusted with the spring knob located on the rear of the swing
arm assembly. (Fig. 24)

2. The hood may be locked in any position by tightening the

hood lock handle located on the right side of the hood.
(Fig. 25)

Note: It is recommended the hood be locked in the upper posi­tion when removing or swinging the boom and hood assembly
from the saw.

3. The length of the telescoping boom may be adjusted by loos-

ening the boom clamp knob and sliding the inner boom
in or out as required. (Fig. 26)

Note: Do not over-tighten the clamp knob. It takes little pres­sure to clamp the boom securely.

Fig. 24

Fig. 25

Fig. 26

4. The bottom lock knob located on the boom mount channel
may need to be adjusted. Loosen the lock nut on the
threaded lock pin and turn the handle in the desired direction
to tighten or loosen the lock. (Fig. 27)

Note: The pin needs to swing just past center to lock properly.

5. To remove the boom assembly from the saw, release the lock
pin (Fig. 28), swing the boom assembly back and lift it off the
pivot pins. (Fig. 29)

CONNECTING TO A DUST COLLECTOR

11

Fig. 31

BEFORE STARTING THE TABLE SAW, CONNECT TO A DUST COLLECTION SYSTEM.

ALWAYS TURN ON THE DUST COLLECTOR BEFORE STARTING THE TABLE SAW AND ALWAYS STOP THE TABLE
SAW BEFORE TURNING OFF THE DUST COLLECTOR.

• Connect a 4” dust hose (not included) from your dust col­lector to the bottom of the boom assembly. (Fig. 31)

• Check that all connections are sealed tightly to minimize
airborne dust.

• If you do not already own a dust collection system consider
contacting your GENERAL® INTERNATIONAL distributor for
information on our complete line of dust collection systems
or visit our Web Site at: www.general.ca

Fig. 27

PARALLEL BOOM ADJUSTMENT

1. Adjust the hex head stop bolt in or out as needed to align
the boom parallel to the front and back edges of the saw.
(FIG. 30)

2. With the boom alignment set, tighten down on the nut to
secure the bolt in place.
