Craftsman 113.29921 owner manual Probable Cause, Into blade

Motor

NOTE: Motors used on wood working tools are particularly susceptible to the accumulation of sawdust and wood chips and shouId be blown out or "Vacuumed" frequently to prevent interference with normal motor ventilation

Trouble	Probable Cause
FExcessive Noise	1 Motor

Remedy

1 Have motor checked by qualified service technician

Repair service is available at your nearest Sears store.

Motor fails to develop full power NOTE: Low Voltage:

(Power output of motor decreases rapidly with decrease in voltage at motor terminals For example, a reduction of

110% in voltage causes '.areduction of 19% in

maximum power output of which the motor is capable, and a reduc- tion of 20% in voltage causes a reduction of 36% in maximum power output.)

t Circuit overloaded with lights, appliances and other motors

2Undersize wires or circuit too long

3.General overloading of power company facilities r(in some sections of the country, demand for electrical power may exceed the capacity of existing generating and distribu-

tion systems )

4Incorrect fuses of circuit break- era in power line

1 Do not use other appliances or motors on same cir- cuit when using the saw

2. Increase wire sizes, or reduce length of wiring. See

"Motor Specifications and electrical Requirements" section

3 Request a voitage check from the power company

4. Install correct fuses or circuit breakers
