Dust Collection
Your table saw is equipped with a dust
shroud and dust collection port. For best
results, connect a vacuum to the port at
the rear of the saw.
After extended use, the saw's dust
collection system may become clogged.
To clear the dust collection system:
1. Unplug the saw.
2. Turn the saw on its side, so the
bottom, open part of the unit is
accessible.
3. Open the dust access door (A4)
shown in Figure 42 by removing
the hair pin cotters (A5). Clean out
the excess dust, and re-secure the
access door with the cotters.
Motor Overload
WARNING: If power is interrupted by a circuit breaker trip, make sure the switch is in the
OFF position before restoring power to prevent the saw from starting unexpectedly.
Circuit breaker overload is often the result of a dull blade. Change your blade on a regular
basis to avoid tripping your breaker. Check your blade before re-setting the circuit breaker
and continuing to saw.
Circuit Breaker Reset Button
The saw is equipped with a 25 amp circuit breaker (H). If this saw
becomes overloaded and stops operating, turn off the saw,
let the unit sit for two minutes and press the reset button
before you resume working (Fig. 43).

MAINTENANCE
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.
Cleaning
WARNING: Blowing dust and chips out of the motor housing using clean, dry
compressed air is a necessary regular maintenance procedure. Dust and chips containing
metal particles often accumulate on interior surfaces and could create an electrical shock
or electrocution if not frequently cleaned out. ALWAYS WEAR SAFETY GLASSES.
CAUTION: When cleaning, use only a damp cloth on plastic parts. Many household
cleaners contain chemicals which could seriously damage plastic. Also, do not use
gasoline, turpentine, lacquer or paint thinner, dry cleaning fluids or similar products which
may seriously damage plastic parts. Never let any liquid get inside the tool; never immerse
any part of the tool into a liquid.
Lubrication
1. All motor bearings are permanently
lubricated at the factory and no
additional lubrication is needed.
2. The height adjustment screw may
require periodic cleaning and
lubrication. If you have difficulty
raising or lowering the blade:
a) Unplug the saw.
b) Turn the saw on its side, so the
bottom, open part of the unit is
accessible.
c) Clean and lubricate the height
adjustment screws threads (A6)
on the underside of your saw with
general purpose grease, shown
in Figure 44.
