Motor Overload and Power Loss Reset Switch
If power is interrupted by a circuit breaker trip, or power is lost, the saw contains a power loss
reset switch feature that will automatically reset to OFF position.
Circuit breaker overload is often the result of a dull blade. Change your blade on a regular
basis to avoid tripping your breaker. Disconnect the saw from power source and check your
blade before re-setting the circuit breaker and continuing to saw.
Lubrication (Fig. 44)
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 screw threads (ZZ)
on the underside of this saw with general purpose grease.
Refer to Figure 44.
STORAGE (Fig. 45–50)
1. Attach push stick (V) to fence.
2. Remove blade guard assembly (K). See Remove Blade Guard Assembly. Slide blade
guard assembly into holder as shown, then turn lever counterclockwise to lock.
3. Depress the stem on the anti-kickback assembly (N) to allow the assembly to slide from the
riving knife slot.
4. Position anti-kickback assembly into the storage hole as shown. While depressing stem (II)
slide the anti-kickback assembly across the storage bracket (A1) and release pin to lock into
place.
5. Slide blade wrenches (U) into pocket until yellow button aligns with hole to secure in place,
refer to Figure 47.
6. Insert guide bar of miter guage (J) into pocket, then pivot and snap in place (Fig. 45).
7. Wrap cord in this location (A2, Fig. 46).
8. Non thru-sawing riving knife (W) slides in place underneath the saw, below the cord wrap.
Refer to Figure 50.
9. To store fence (K), snap work support in stored position. Remove fence from rails. Reattach
fence upside down on left side of saw. Refer to Figure 46. DO NOT hook locator pins on left
side fence locator screws. These screws will align with clearance pocket on fence as shown.
Pivot fence lock latches to secure.
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.
