Rules for Safe Operation

To help ensure safe operation, please take a moment to learn the machine’s applications and limitations, as well as potential hazards. General International disclaims any real or implied warranty and hold itself harmless for any injury that may result from the improper use of it’s equipment.

1. Be sure to read, understand and follow all warnings and safety guidelines supplied with your table saw and dust collector.
2. Do not use any machinery when tired, distracted, or under the effects of drugs, alcohol or any medication that impairs reflexes or alertness.
3. Keep safety guards in place and in working order.
4. Keep work area well lit, clean and free of debris.
5. Do not use tools in dangerous environments. Do not use power tools in damp or wet locations or expose them to rain.
6. Keep children and visitors at a safe distance when machinery is in operation. Do not permit them to operate any machinery.
7. Childproof and tamper proof your shop and all machinery with locks, master electrical switches and switch keys, to prevent unauthorized or unsupervised use.

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 anti-kickback 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 accom-modate 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)

MOUNT THE HOOD ASSEMBLY TO THE INNER BOOM

1. Slide the hood assembly a over the end of the inner boom b , 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 c through the two holes in the band clamp section of the mount on the under-side. Thread on a 1/4” lock nut d and tighten. ( Fig. 3)

INSTALL THE DUST HOSE

Install the dust collection hose a between the hood and the inner boom using the two supplied hose clamps b , 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 approxi-mately 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

1. Insert the extension leg a into the upper leg of the boom  mount channel b . (Fig. 9)
2. Use the two supplied lock knobs c 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 a on the  boom mount with the center of the blade b . (Fig. 11)
2. Note: Because the slots in the boom mount channel are elongated – allowing for fine tuning later, perfect alignment is not critical at this stage.
3. 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)
4. 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.
5. Note: For ideal installation, use bolts in all 6 mounting slots.
6. Using less than 4 slots (2 at each end) is not recommended and can lead to system failure and seri-ous personal injury.
7. Set the boom mount channel aside and drill through-holes in the extension table apron. (Fig. 13)
8. Secure the boom mount channel to the extension table using the supplied mounting hardware a in the order shown. (Fig. 14)
   Note: The supplied mounting hardware will accommodate a typical installation with a table apron of up to 3/4” thick. For thicker aprons, longer bolts (not supplied) may be required.

DIAGONAL BRACE INSTALLATION

1. Attach the straight end of the diagonal braces to the tabs at the lower end of the boom mount support leg using two 1/4” x 1/2” bolts, a, lock washers, b, and hex nuts c. (Fig. 15)
2. Swing the diagonal braces into position on the underside of the extension table. (Fig. 16)
3. Mark the hole placement and drill suitable holes to accomodate bolts or woodscrews. (Not included)
4. Fasten the braces to the underside of the table. ( Fig. 17)

FIT THE BOOM TO THE BOOM MOUNT CHANNEL

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 a 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, a ) 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 a located on the right side of the hood.(Fig. 25)
   Note: It is recommended the hood be locked in the upper posi-tion when removing or swinging the boom and hood assembly from the saw.

3. The length of the telescoping boom may be adjusted by loosening the boom clamp knob b and sliding the inner boom in or out as required. (Fig. 26)

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

5. The bottom lock knob located on the boom mount channel may need to be adjusted. Loosen the lock nut a 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.

6. 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)

PARALLEL BOOM ADJUSTMENT

1. Adjust the hex head stop bolt a 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 b to  secure the bolt in place.

CONNECTING TO A DUST COLLECTOR

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 col-lector 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
