BASIC FUNCTIONS OF THIS UNIT
The 50-EXBC-CM is designed as a ceiling mounted blade cover and dust collection hood only. It is intended for use
on 10” (model 50-EXBC-CM10) or 12-14” (model 50-EXBC-CM14) 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 EXBC-CM Blade Cover is designed to connect to any 4”dust collection system to remove saw dust at the source
directly above the blade. The blade cover is intended to be mounted independent of the saw, usually to a column
hung from the ceiling of the workshop. The short 3” diameter boom tube incorporates welded mounting brackets,
allowing a wide variety of mounting arrangements.

MOUNT THE HOOD ASSEMBLY TO THE BOOM ASSEMBLY
1. Slide the hood assembly over the end of the
boom leaving approximately 1” of the boom protruding past the mount .
2. Tighten the nut to secure the hood assembly to
the boom.
1”
Approximately 1” protruding for
hose installation
INSTALL THE DUST COLLECTION HOSE
Install the dust collection hose between the hood
and the boom using the two supplied hose clamps
as shown in .
MOUNT THE ASSEMBLY
1. Raise the saw blade to its full upper position and set
the complete EXBC-CM assembly on the saw table
so that the hood covers the blade. The back of the
hood should be 3” to 4” behind the saw blade .
The blade should be able to tilt to 45° without touching the side lenses. This will determine the mounting
position of the boom tube relative to the saw.
2. Devise a means of mounting the boom . It should
be mounted horizontally, with the underside of the
boom 14 1/2” above the saw table . The boom
may be rotated so the mounting brackets are vertical or horizontal . It may be suspended from
the ceiling using any convenient pipe, tubing or
lumber. If the ceiling is quite high, some form of
bracing or guy wires may be necessary to provide
stability.
Note: Make sure your support column (pipe, tube,
lumber etc.) is properly secured to a structural member such as a beam or joist.
3” to 4”
14 1/2”

ADJUSTMENTS
1.
The resistance or balance of the hood assembly
can be adjusted with the spring knob located on
the rear of the hood assembly.
2. The balance of the hood can also be affected by
changing the preload exerted on it by the hose. To
do this, loosen the hose clamp that secures the
hose to the inner boom and rotate the hose on the
boom. Rotating the hose clockwise will tend to lift
the hood, while rotating it counter clockwise will
push the hood down towards the table.
3. The hood may be locked in any position by tightening the hood lock handle located on the right
side of the hood.
CONNECT 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 collector to the boom assembly.
• 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:
