using a power tool. They are easily installed between the power receptacle and the cord. Leakage of current will

shut off the tool, preventing possible serious injury from electrocution.

WARNING

The dust generated by most materials including plastics, metals, wood, and wood tools can be injurious to your

health. Always operate tool in a well ventilated area and provide for proper dust removal. Use appropriate dust

collection systems whenever possible.

Table Saws Are Very Dangerous

All Table Saws are inherently dangerous and should never be used by anyone who is not thoroughly trained and

experienced. The Brett-Guard Table Saw Safety Tool, properly installed and used under proper supervision, can

help to protect an operator against injury from many saw hazards such as coming in contact with the saw blade,

kickbacks and flying splinters but NOTHING can protect an operator if proper operating procedures are not followed.

It is the responsibility of those making the set-up on a table saw to first determine if there is not a safer way to

accomplish the desired result.

Component Descriptions

Components

1. Vertical Adjustment Crank Handle — The handle on top of the saw guard housing raises and lowers the

transparent safety shield assembly to fit the height of the workpiece.

2. Locking Knob — The hand knob located on top of the saw guard housing, next to the Vertical Adjustment Crank

Handle, is used to lock the saw guard housing assembly to the mounting plate and to release it.

3. Transparent Safety Shield — An inverted box type guard that permits the saw blade and work-piece to be seen.

Must always be in contact with the workpiece. The Anti-Kickback mechanism is an integral part of the shield.

4. Horizontal Shield Adjustment Lock Knobs — Hand knobs located on the front and rear of the saw guard housing

lock the 1/2" diameter horizontal bars in position.

5. Anti-Kickback Adjustment Lock Knob —Raises and Lowers the Anti-Kickback device located in the safety shield.

6. Shield Support Rods —Connects the Safety Shield to the adjustment mechanism.

7. Locking Rod — Locks the Safety Tool in the Down and Locked Position. Is rotated by the Locking Knob.

8. Vertical Adjustment Screw — Provides positive control for the raising and lowering of the safety Shield Assembly.

It is operated by the Vertical Adjustment Crank Handle. Lubricate frequently for smooth operation and extended life.

9. Vertical Guide Bars — Serves to keep the Safety

Shield stable. When the Safety Shield begins to get

loose and sag these must be replaced along with their

companion bushings.

10. Housing — The complete raising, lowering, locking,

and adjustment mechanism.

11. Splitter — Mounts to the saw blade trunnion and must

be directly in line with the saw blade. It serves to keep

the kerf of the workpiece from closing up on or pinching

the saw blade. This must be in place during all cutting

operations where the saw blade is cutting all the way

through the workpiece. Thin kerf splitter also available.

Operating Instructions

The use of the BRETT-GUARD Table Saw Safety Tool (Guard) is basically quite simple. But, due to the serious nature

of operating a table saw, there are many factors to be considered. The following pages show most of the important

factors to consider for safe table saw operation. It must be pointed out that some operations are safer, when done

with other equipment.

WARNING: NEVER MAKE ANY ADJUSTMENTS WHILE BLADE IS ROTATING.

Locking Guard into Position

1. Position the Saw Guard Housing over the Mounting Plate. Align the two (2) locator pins with the two (2) holes in the

Mounting Plate. Set the housing on the plate.

2. Rotate the Locking Knob until the Locking Rod drops

into the key hole on the Mounting Plate.

3. Rotate the Locking Knob clockwise. A mechanical stop

is reached after 1/2 revolution. The guard is now locked

to the Mounting Plate.

NOTE: You should notice some resistance when

rotating the Locking Knob. If not it should be adjusted.

Refer to maintenance instructions on page 9.

Unlocking Guard

1. Make sure that the power is off to the machine.

2. While supporting the guard, rotate the Locking Knob counter-clockwise and lift.

WARNING: NEVER LEAVE THE BLADE UNGUARDED.

Procedure to Change / Access Saw Blade

1 Disconnect power to the machine. Observe OSHA Lock-Out Procedures.

2. Loosen the horizontal shield adjustment Lock Knobs and slide the shield toward the housing.

3. When saw blade service is completed, return shield to proper position

4. Restore Power.

Anti-Kickback Adjustment

The anti-kickback mechanism is an integral part of the Safety Shield and the Anti-Kickback Adjustment Knob (5) is

located on the top of it. The Anti-Kickback fingers are spring loaded. The Knob provides an adjustment range from

Retracted to Full Pressure. It is recommended for most table saw set-ups that the Anti-Kickback mechanism be engaged.

Warning: The safety shield must be in contact with the workpiece for the Anti-Kickback Device to function. The

Anti-Kickback Device is effective only when the Brett-Guard is mounted on the left side, and the Anti-Kickback

Device engages the workpiece. The Anti-Kickback Device is inoperative when the Brett-Guard is used in the right

and rear positions.

Safety Shield Adjustments

Vertical Adjustments

The height of the Safety Shield is very important. The Vertical Adjustment Crank Handle is used to raise and lower the

shield. (See Page 4 - Component Descriptions)

Horizontal Adjustments

1. With the guard locked to the mounting plate, loosen the two Horizontal Shield Adjustment Knobs.

2. Position the shield right or left as required. The recommended position is for the Anti-Kick Fingers to be centered

over the line of the blade. Refer to typical set-ups page 6 and 7.

3. Retighten the Lock Knobs.

Engage Material

Anti-Kickback Fingers

Warning: For the Anti-Kickback device to function and/or the Shield to serve as a hold-down device, it is

imperative that the shield be adjusted so that the lower edge of the shield applies a light pressure to the top of

the workpiece.

Leveling

The Safety Shield must be kept parallel with the top of the saw table or the Anti-Kickback feature on the guard will not

function correctly. This detail is very important and should be checked regularly. A series of Set Screws are used to level

the mounting plate to the saw table. Refer to Assembly and Installation.

Squaring

The edge of the Safety Shield is to be kept parallel to the saw fence. To adjust-

1. Loosen the four (4) mounting screws that secure the Safety Shield to the Shield Support Rods.

2. Lock the saw fence up against the side of the shield. Then retighten the four (4) mounting screws.

Caution: The saw table and fence must first be squared to the saw blade

Typical Set-ups

Warnings:

1. Never operate a Table Saw without a properly mounted and positioned Saw Guard. Use of an improperly guarded

saw will result in serious injury.

2. Properly position guard BEFORE turning on the saw motor.

3. Do not adjust guard or blade position while saw motor is running or even while blade is rotating.

4. Make certain the Anti-Kickback device is properly adjusted.

5. Never reach or let hands slip under the shield.

6. Always wear proper eye protection while operating a table saw.

7. LOCKOUT POWER before changing the blade or servicing the machine.

8. Worn or damaged parts, on the saw or the guard, must be replaced before operation is continued.

When ripping narrow stock always use a Push-Stick. Always use outfeed support for long stock.

6. Always stand to the side of the blade.

7. Use proper size push plate for small pieces.

Cross-Cutting Reminders:

Note: The original Brett-Guard can be used in any

position for cross-cutting

1. When possible use the Brett-Guard in the left

position to take advantage of the Anti-Kickback

mechanism

2. Always have the splitter installed.

3. Always stand to the side of the blade.

4. Rip Fence should be positioned on the opposite side

from the guard, away from the material being cut, or

removed completely.

5. Always lower the shield so that it rests gently on the

workpiece.

Assembly and Installation

The original model Brett-Guard is shipped from the factory with the mounting plates and hardware specific to your order.

1. Attach the two steel shield support rods to the acrylic shield with four (4) #10-24 x1" screws and nylon washers in

the threaded holes provided in the steel rods. Position rods on the inside of the shield, with nylon washers between

the shield and the head of the screw.

2. Thread two (2) 5/16 - 18 x 1" Lock knobs into the Brett-Guard housing as shown on Page 4 - Component Description.

3. Insert the shield support rods into the housing slide and lock into position with the knobs installed in previous step.

Set this assembly aside.

4. Review Figure 3. You will note the key shaped holes in the left and right plate must correspond exactly to the axis of

the saw arbor. Locate and mark line “T” on the saw surface, with an easily removable marker or pencil.

5. If a rear plate is to be installed, locate and mark line “L” as well, using the proper off-set as indicated in Figure 3.

6. Clamp the mounting plate onto the edge of the table, flush with the surface, key shaped hole toward the blade. Key

shaped hole in plate should be centered on the line located in Step 4.

7. Mark the locations of the mounting holes, using the large holes (2) in the plate as your guide.

8. Remove the mounting plates and center punch the locations of mounting holes marked in previous step for drilling.

9. Drill 7/16" through holes in the table edge at the center punched locations. If the table edge is thicker than 1/4", you

may want to drill and tap the holes.

10. Attach the mounting plate to the table edge with 3/8" -16 x 1" bolts, washer, lockwasher and hex nuts provided.

11. Leveling the plate to the table surface is easily accomplished by installing the provided set screws above or below

the mounting bolts. Slightly loosen the mounting bolts and tighten the set screws to gain the required adjustment.

12. Repeat this same procedure for mounting right side plates.

Brackets and Rear Plate Installation

The type of arrangement for mounting a rear plate will vary based on your saw and was determined at the time of order.

Review Figures 4 and 5.

1. Fasten the left and right brackets to the rear box plate on the inside edge. Use two (2) 5/16" - 18 x 1" bolts,

washers, lockwashers, and hex nuts on each side. Make sure the key shaped hole will face the saw blade.

Note - Steps 2-5 will require a helper.

2. Using the reference line drawn on the table saw, (Figure 3) align the key shaped hole with mounting brackets held

against cabinet back.

3. Check to be sure the plate is low enough to permit clearance of the rip fence and miter gauge guide bar.

4. Now check the side clearance between the miter gauge guide and the Brett-Guard housing.

5. Mark and center punch the hole locations in the cabinet

using the holes in the mounting brackets as a guide.

Drill 1/8" pilot holes at the center punched locations.

Then enlarge with 11/32" drill to accommodate 5/16"

mounting bolts.

6. Attach mounting brackets to the cabinet with four

5/16" - 18 x 1" bolts and flat washers from the inside

of the cabinet. Feed the bolt through the mounting

bracket and secure with flat washer, lock washer, and

hex nut.

7. Before tightening the bolts, lock the Brett-Guard onto

the rear plate. Lower the shield until it is about 1/4”

from the table top. Tap the mounting plate gently until

the shield is level with the table top.

8. If the guard is not parallel with the blade, insert shims

under the left or right bracket until it is parallel. Tighten

Arms and Rear Plate Installation

1. Remove the existing extension wings from the saw.

2. Check the alignment of the pre-drilled holes in the

arms, with the existing holes in the table edge. If they

do not match, you will need to drill new through holes

in the arms to match the existing holes in the table.

3. Remount the extension, sandwiching the arms

between the table and the extensions. Arms should be

flush or slightly below the table.

4. Attach the rear mounting plate to the arms using (4)

5/16" - 18 x 1" bolts, flatwashers, lockwashers and

hex nuts. Hand tighten only.

5. Lock the Brett-Guard onto the rear plate. Lower the

shield until it is about 1/4" from the table top. Gently

tap the plate until the shield is level with the table and

tighten all fasteners.

Maintenance Instructions

Warning: Disconnect all power from machine

before performing any service operations.

Safety Shield

The Safety Shield should be cleaned daily if used

continuously. Most sawdust can be blown off with

compressed air, if available. If not, brush or wipe off with a

soft grit-free cloth. Ordinary non-abrasive soap and warm

water or denatured alcohol will remove wood resins.

Warning: Do not use any solvents such as

acetone, benzene, carbon tetrachloride,

dry-cleaning fluid or lacquer thinner.

Locking Rod Adjustment

While turning the Locking Knob it should tighten slightly

before it reaches the locked position. If not make

adjustment as follows:

1. Put guard in the Down & Locked position.

2. Using two 11/16" wrenches, loosen the top of the two

nuts underneath the Locking Knob.

3. Turn the bottom nut until it begins to snug up.

4. While holding the bottom nut steady, with one wrench,

tighten the top nut against it, with the other wrench.

5. Check by turning the Locking Knob. If it is still loose,

repeat steps above. If it will not relock, back off on the

adjustment.
