Troubleshooting, Keep Machine Clean, Failure to Start

OUT-RIPPING

Out-ripping is generally the same as ripping except that you clamp the yoke at a right angle to the track arm with the blade guard facing the front of the machine. Position the cuttinghead on the out-rip scale to the desired setting and clamp it in position. Feed the workpiece from the left side of the saw. A typical out-ripping operation is illustrated in Fig. 61.

IN-RIPPING

In-ripping is generally the same as ripping except that you clamp the yoke at a right angle to the track arm with the blade guard facing the rear of the machine. Position the cuttinghead on the in-rip scale to the desired setting and clamp it in position. Feed the workpiece from the right side of the saw. A typical in-ripping operation is illustrated in Fig. 62.

When ripping a workpiece less than 6" wide, use a push stick to complete the feed (Fig. 62).

PUSH-STICKS

In order to operate your radial arm saw safely, you must use a push-stick whenever the size or shape of the workpiece would cause your hands to be within 6" (152mm) of the saw blade or other cutter.

No special wood is needed to make a push-stick as long as it's sturdy and long enough. A length of 12" (305mm) is recommended with a notch that fits against the edge of the workpiece to prevent slipping. It's a good idea to have several push-sticks of the same length [12" (305 mm) with different size notches for different workpiece thicknesses.

See the next page for an illustration of a push-stick. The shape can vary to suit your own needs as long as it performs its intended function of keeping your hands away from the blade.

Maintenance

To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

KEEP MACHINE CLEAN

Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

Wear certified safety equipment for eye, hearing and respiratory protection while using compressed air.

FAILURE TO START

Should your machine fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line.

LUBRICATION & RUST PROTECTION

Apply household floor paste wax to the machine table, extension table or other work surface weekly. Or use a commercially available protective product designed for this purpose. Follow the manufacturer’s instructions for use and safety.

To clean cast iron tables of rust, you will need the following materials: a sheet of medium Scotch-Brite™ Blending Hand Pad, a can of WD-40®and a can of degreaser. Apply the WD-40 and polish the table surface with the Scotch-Brite pad. Degrease the table, then apply the protective product as described above.

OVERLOAD PROTECTION

The motor on your saw is equipped with an overload relay (A) Fig. 63. If the motor shuts off or fails to start due to overloading, or low voltage, turn the switch to the “OFF” position, let the motor cool three to five minutes then push the reset button (A). The motor can then be turned on again in the usual manner. Some conditions that may cause overloading are; cutting stock too fast, using a dull blade, using the saw beyond its capacity, etc.
