EXAKTOR®INDUSTRIAL OVERARM
EXOA-2 BLADE COVER/DUST COLLECTOR
Your EXAKTOR®EXOA OverArm Blade Cover/Dust Collector can be used with most table
saws. Coupled to an appropriate dust collection system, the OverArm Blade Cover/Dust Collector
helps control airborne dust thrown up by the revolving saw blade.
The EXOA-2 features a counter-balanced Guard Basket that accommodates saw blades up to 16”
in diameter, raised up to 4” above the table and tilted for cuts to 45 degrees. You can be quickly
position the Guard Basket to suit the saw blade and the material being cut, and it is equipped to
accommodate the splitter and anti-kick-back pawls that are installed on your table saw. When you
are changing blades the telescopic Boom and Guard Basket will swing easily out of the way.
The top surface and sides of the steel framed Guard Basket have shatterproof Lexan¥lenses,
which give you a clear view of the saw blade at all times. The ‘baffling’ effect of the Guard
Basket and the flexible hose connecting the Guard Basket to the telescopic Boom makes dust
extraction very efficient.
Installation is exceptionally easy. The vertical mast stands on the floor and is adjustable to the
height of the saw table.
The mast is fastened to the side of the saw table or table extension with two quick release levers.
For quick removal, these levers release the upper part of the mast. The mast supports a telescopic
four-inch diameter boom equipped for coupling to a 4” vacuum hose. The boom length is
adjustable to allow the saw fence to be positioned up to 70” from the saw blade.
The EXAKTOR®EXOA-2 Blade Cover/Dust Collector has been carefully designed to fit and
work with your table saw. It will add an element of safety and its built-in dust collecting
capability will provide you with cleaner air to breathe.
Designed for Dust
Collection Only
The EXAKTOR®EXOA-2 OverArm Blade Cover/Dust Collector is sold for dust collection only.
It must be used with, and does not eliminate the need for, anti-kick-back and splitter devices.
These devices are not supplied with the EXOA-2 OverArm Blade Cover/Dust Collector. The
provision of a splitter and anti-kick-back device is the responsibility of the saw owner and/or
user.

TABLE SAW SAFETY
1. To prevent accidents keep safety in mind while you work.
2. Use the safety guards installed on powered equipment. They are for
your protection.
3. When working on powered equipment keep fingers away from saw
blades and cutters.
4. Wear safety goggles to prevent injuries from flying wood chips and
saw dust.
5. Wear headphones to protect your hearing.
6. Consider installing a dust vacuum to reduce the amount of airborne
dust in your workshop.
7. Don’t wear loose clothing, such as neckties or shirts with loose
sleeves, or jewelry, such as rings, necklaces or bracelets when
working on power equipment.
8. Tie back long hair to prevent it from getting caught in powered
equipment.
9. Keep work areas clean. Cluttered areas invite accidents.
10. Do not force work though the machine. Tools work better and are
safer when they work at their own speed.
11. Do not overreach. Keep proper footing and balance at all times.
12. Do not reach behind the machine to grab a cutoff piece. If the wood
binds behind and against the blade or cutter it will kick back faster
than you can let go.
13. Disconnect the machine from electrical power before servicing and
changing accessories, such as blades and cutters.
14. Never leave the machine running unattended – turn the power off.
15. Do not leave the machine until it comes to a complete stop.
16. Do not operate the machine if you are mentally or physically
fatigued.
17. If there is something that you do not understand, do not operate the
machine! Ask for help first.
These safety rules do not cover every situation in a workshop.
Consider your conditions when using your EXAKTOR®Blade Cover.

EXAKTOR®EXOA-2 BLADE COVER
DUST COLLECTOR
Installation
The EXAKTOR®BladeCover/Dust Collector has been designed to fit most table saws with its vertical Mast installed at
either the right or left hand side of the machine. In most cases the vertical mast will be installed at the right hand end of the
saw’s table or table extension, close to the rear edge of the table.
Mast Assembly
1. With the Lower Mast (#1) resting on the floor, insert it into the bottom end of the Upper Mast (#2).
Adjust the overall length of the Lower and Upper Masts to where the top edge of the slotted Mounting Bracket,
that is welded on the side of the Upper Mast, will be just below the top surface of the saw’s table or table
extension. Lock the two Masts together with a Locking Knob (#3).
2. Carefully place the slotted mounting bracket against the edge of the saw table, or table’s extension, close to
the rear
edge of the table. Make sure there is clearance behind the edge of the table to accommodate the Backing Plate
(#15). Its two threaded holes must line-up with the slot in the mounting bracket.
3. Using the slots in the Mounting Bracket as a
template, drill a 1/4” hole at the top of each slot,
through the edge of the table. Using two Locking
Levers (#4) and the Backing Plate (#15), fasten
the Mounting Bracket to the edge of the table.
4. The diagonal brace is used to hold the
vertical mast in position. Use a ¼-20 x 1¼” Hex
Head Bolt (#6), Washer (#7) and ¼-20 Nut (#8)
to attach one end of the Mast Brace (#5) to the
bracket at the bottom end of the Lower Mast
(#1).
5. Position the assembled Lower and Upper
Mast so
that it is vertical to the floor and square to the
surface of the saw table. Determine where to
place the
unfastened end of the Mast Brace up under the
rear edge of the saw’s table, or table extension so
that when the brace is fixed in place, and the
turnbuckle is tightened, the assembled Mast will
be held vertical and square to the table surface
and will not shift from that position. Drill an
appropriate hole in the rear edge of the saw table
or table extension and attach the upper end of the
Mast Brace to the edge of the underside of the table.
Use Hex Head Bolt (#6), Washer (#7) and Nut (#8).

Boom Assembly
Note: Thermoplastic and UHMW spacers are
used in the telescopic boom assembly. Their
purpose is to provide a smooth bearing surface
and to take up the play between the tubular
sections of the Boom. Pay close attention to how
the Small Boom Tube is inserted into the Large
Boom Tube, i.e. the Small Boom Tube can only
be inserted and extended one way.
6. The telescopic Boom is shipped with the
Small Boom Tube (#13) inserted into the Large
Boom Tube (#12). A ¼-20 x Ǫ” Button Head
Bolt (#21) and Nut (#22) are installed on the
underside the outboard end of the Small Boom
Tube.
7. There are two Ǫ” holes 6” apart, in the Large
Boom Tube for attaching the Boom Saddle (#9).
Push the Small Boom Tube out through the Large
Boom Tube to gain access to these two Ǫ” bolt
holes from inside the Large Boom Tube
8. With the threaded hole in the tubular section
of the Boom Saddle (#9) facing in the direction
of the Small Boom Tube, use two ¼-20 x Ǫ”
Button Head Bolts (#21) and ¼-20 Lock-nuts
(#22), to firmly attach the Boom Saddle to the
Large Boom Tube.
9. Place the tubular section of the Boom Saddle
(#9), over the top end of the Mast assembly.
10. Use a Locking Knob (#3) to secure the Boom
Saddle to the Mast.

Guard Basket Assembly
12. Position the large Roller Wheel (#41) at the front end of the Guard Basket and attach it with a ¼-20 x1-1/4”
Shoulder Bolt (#6) and 10-24 Ny-Lock Nut (#44) with a 6mm washer (#19) placed under the head of the Bolt
and under the Ny-Lock Nut.
13. Position the small Roller Wheel (#45) at the back end of the Guard Basket and attach with a ¼-20 x 1¼”
Shoulder Bolt (#6) and 10-24 Ny-Lock Nut (#44) with a 1/4” washer (#19) placed under the head of the Bolt
and under the Ny-Lock Nut.
14. Use 20 Button ¼-20x Ǫ”Head Bolts (#21) and ¼-20 Nuts (#22) to assemble the Guard Basket Frame (#16)
with the Top Lens (#20) and the two Side Lenses (#19).

1/13/2005
9
Suspension Assembly
15. Use Ǫ-18 x 1¼” Shoulder Bolts (#31) and
5/16-18 Ny-Lock Nuts (#40) to secure the rear end
of the Long Arm (#25) and the Short Arm (#26)
to the Boom Clamp (#29).
16. With a Star Washer (#33) under the head of a
Shoulder Bolt (#31), secure the forward end of
the Long Arm (#25) to the top of the Vertical
Arm (#27) using 5/16-18 TPI T-Knob (#28).
17. Secure the forward end of the Short Arm
(#26) to the middle of the Vertical Arm (#27)
with a Ǫ-18 x 1¼”Shoulder Bolt (#31) and 5/16-
18 TPI Ny-Lock Nut (#40).
18. Insert the plastic End Caps (#34) into the
forward end of the Long and Short Arms. If the
Caps tend to be a loose fit, you can use a rubber
band stretched around the ribs of the cap to
eliminate any play.

1/13/2005
19. Use a Hose Clamp (#24) to secure one end of the
Flexible Hose (#23) to the top of the Guard Basket
Frame.
20. Use a Locking Lever (#35) and the Slide Bar (#18)
to attach the Vertical Arm to the channel located
on the top surface of the Guard Basket Frame.
21. With the bottom edge of the Guard Basket seated
squarely on the saw table, position the Boom Clamp
(#29) approximately 2” in on the open end of the
Small Boom Tube (#13). Secure by using a T-Knob
(#30) with ¼-20x3½” Carriage Bolt (#39).
22. Use a Hose Clamp (#24) to secure the open end of
the Flexible Hose (#23) to the open end of the Small
Boom Tube (#13).
23. Insert the Counter Weight (#32) into the tail end of
the Long Arm (#25) and secure with the counter
weight Locking Knob (#3).
Adjusting and using the EXOA-2
Blade Cover
24. Adjust the length of the Boom Tubes to position
the Guard Basket over the saw blade. Lock the Tubes
in position with Knob (#3). Adjust the ¼-20xǪ”
Button Head Bolt (#21) installed on the underside the
outboard end of the Small Boom Tube to take-up any
play between the Small and Large Boom Tubes and
secure with the ¼-20 Jam Nut (#22).
25. N/A.
26. Position the Guard Basket forward or backward,
over the saw blade, so that the opening to the Flexible
Hose is centered above the saw blade. Secure the
Guard Basket using the blade cover Lever (#35).
27. The rear of the Guard Basket has two vertical slots
to allow the basket to come down over a splitter
located behind the saw blade. Use the four 6-32x½”
Pan Head Screws (#46) to attach a Cover Plate (#36 or
#37) to cover one or both slots as desired.
28. Position the Counter Balance so that the weight of
the Guard Basket is easily raised when material can be
passed under the front Roller Wheel. For thicker
material raise the Guard Basket and place it on top of
the material. The roller wheels should just touch and
roll on the top surface of the material being cut.
29. If cutting work taller than the Guard Basket when
it’s raised to its highest position above the saw table,
the Guard Basket and Boom can be swung out of the
way by loosening the Locking Knob (#4) in the Boom
Saddle.
30. If the Mast is in the way when crosscutting longer
material, the Upper Mast and Boom assembly can be
easily removed by loosening the two Locking Levers
(#4) and the Locking Knob (#3) in the lower end of the
upper mast.
Optional Casters
An optional pair of casters is available for those who
want to have the ability to move the location of the
their table saw with the EXOA-2 Blade Cover
remaining attached to the saw. The plate at the bottom
of the mast has two holes in which the casters (#50)
can be easily installed.
