WARNING: Always use push sticks, feather-
boards, push paddles and other safety acces-
sories whenever possible to increase safety and
control during operations which require the
blade guard and splitter to be removed from
the saw. ALWAYS replace the blade guard after
dadoing is complete.
Proper dado operations will differ depending
on the blade system you choose. Consult the
instructions included with your dado blades
for directions regarding attachment and ad-
justment.
IMPORTANT: MAKE CERTAIN THAT THE SAW
IS DISCONNECTED FROM THE POWER SOURCE.
1. Remove the table insert, splitter guard, and
regular saw blade.
2. Attach and adjust the dado blade system as
recommended in the dado blade's instructions.
3. Install the dado table insert.
4. Raise the blade system up to the desired
depth of the dado. Make sure the dado blade
will not cut through the workpiece.
5. Reconnect the saw to the power source.
6.. If dadoing along the length of your work-
piece, adjust the distance between the fence
and the inside edge of the blade to suit your
needs. When cutting across the wood grain,
use the miter gauge as a guide while dadoing.
Remember: Never use the fence as a stop in
conjunction with your miter gauge.
7. Using a scrap piece as a test piece, switch on
the saw and take a pass over the dado blade.
8. If the cut is satisfactory, repeat with your fin-
ish stock.
9. Avoid taking too deep a cut in a single pass.
Make incremental cuts to avoid kickback.

MAINTENANCE

This table saw requires very little maintenance
other than minor lubrication and cleaning. The
following sections detail what will need to be
done in order to assure continued operation of
your saw.
LUBRICATION
The table saw has sealed lubricated bearings in
the motor housing and the arbor assembly that
do not require any additional lubrication from
the operator. Use a wire brush to clean off the
worm gears and trunnions and apply a white
lithium grease to keep them lubricated.

CLEANING
Keep the inside of the cabinet clear of saw
dust and wood chips. With the table saw un-
plugged, vacuum out the inside of the cabinet
or blow out the inside with an air hose. Be sure
to use air pressure no higher than 50 PSI as
high pressure air may damage insulation.
CHANGING BELTS (FIG. 28)
WARNING: MAKE CERTAIN THAT THE SAW
IS DISCONNECTED FROM THE POWER SOURCE.
1. Lower the blade to
its lowest point.
2. Loosen the hex cap
bolt (a).
3. Take the tension off
of the belts (b) by lift-
ing up on the motor.
4. Remove the belts from the arbor and motor
pulleys.
5. Replace and tension the belts. The weight of
the motor should apply enough tension to the
belts. Tighten the hex cap bolts.
6. Check the belt tension after the saw has
been used for a few hours. Adjust as necessary.

TROUBLESHOOTING
