On-Off Switch (Fig. 29)
WARNING: To reduce the risk of injury, be sure the switch
is in the OFF position before plugging machine in.
Pull the red paddle (H) to turn this saw on and push down the
red paddle to turn the saw off.
LOCK OFF FEATURE INSTRUCTIONS
To lock the saw off, insert a padlock underneath the paddle.
A padlock with a maximum diameter of 1/4" (6.35 mm) and
minimum clearance of 3" (76.2 mm) is recommended.
Guard Detect Operation (Fig 29)
WARNING: Use the blade guard assembly for all thru-sawing.
WARNING: Use the riving knife for non thru-sawing when blade guard assembly cannot
be used.
When there is a need for sawing in which the blade guard assembly cannot be used, the
guard detection system provides the user the ability to operate the saw in a bypass mode at
the user's discretion.
1. With the blade guard assembly not installed, switch saw on. The bypass indicator will
flash indicating that the saw cannot be used in this condition.
2. To bypass, rotate the bypass knob once. The flashing light will change to non flashing,
indicating that the saw can be operated once.
3. Additional cutting requires the bypass to be repeatedly activated.
NOTE: When blade guard assembly is reinstalled, saw will operate without the need to use
the bypass knob.
Guard Operating Feature (Fig. 30)
WARNING: To reduce the risk of injury, turn unit off and disconnect machine from
power source before installing and removing accessories, before adjusting or changing set-
ups or when making repairs. An accidental start-up can cause injury.
1. The guard(s) will lock in place when in the raised position.
2. This feature increases visability when measuring the blade to fence distance.
3. Push down on guard(s) and they will release to the operating position.
NOTE: Pull on the anti-kickback assembly to ensure it is locked in place.
ALWAYS make sure both guards are in the down position in contact with the table before
operating.

RAIL LOCK LEVER (FIG. 32)
The rail lock lever (E) locks the fence in place preventing movement during cutting. To lock
the rail lever, push it down and toward the rear of the saw. To unlock, pull it up and toward
the front of the saw.
NOTE: When ripping, always lock the rail lock lever.
WORK SUPPORT EXTENSION/NARROW RIPPING FENCE
FIG. 29
X
The table saw is equipped with a narrow ripping fence that also supports work that extends
beyond the saw table.
To use the narrow ripping fence in the work support position, rotate it from its stored position
as shown in Figure 31, and slide the pins into the lower sets of slots (A3) on both ends of the
fence.
To use the narrow ripping fence in the narrow ripping position, snap the pins into the upper
sets of slots (A4) on both ends of the fence.
This feature will allow 2" (51 mm) of extra clearance to the blade. Refer to figure 33 B. If more

H
clearance is necessary, follow directions for making an auxiliary fence under Narrow Rip
Auxiliary Fence in the Operation section.
NOTE: When not in use, the narrow ripping fence should be placed in its stored position.
FIG. 31
NOTE: This fence will allow the guard to remain on the saw when completing narrow ripping.
This fence will provide ample space for a push stick. If you prefer more clearance for push
blocks or push sticks, refer to Narrow Rip Auxiliary Fence.
FINE ADJUSTMENT KNOB (FIG. 31)
The fine adjustment knob (D) allows smaller adjustments when setting the fence. Before
adjusting, be sure the rail lock lever is in its up or unlocked position.
RIP SCALE POINTER
The rip scale pointer will need to be adjusted for proper performance of the rip fence if the
user switches between thick and thin kerf blades. The rip scale pointer only reads correctly
for position 1 (0 to 24.5"), however for position 1 with narrow rip fence in use add 2" (50 mm).
OPERATING
See Adjusting the Rip Scale under Assembly.
POSITION
Ripping (Fig. 33)
WARNING: Never touch the "free end" of the workpiece or a "free piece" that is cut off,
while the power is ON and/or the saw blade is rotating. Piece may contact the blade resulting
in a thrown workpiece and possible injury.
WARNING: A rip fence should ALWAYS be used for ripping operations to prevent loss of
control and personal injury. NEVER perform a ripping operation freehand. ALWAYS lock the
fence to the rail.
WARNING: When bevel ripping and whenever possible, place the fence on the side of the
blade so that the blade is tilted away from the fence and hands.
WARNING: Keep hands clear of the blade.
