Craftsman 113.2472T0 owner manual Trouble Shooting -- Motor, Probable Cause

TROUBLE SHOOTING -- MOTOR

NOTE: Motors used on wood-working tools are particularly susceptible to the accumulation of sawdust and wood chips and should be blown out or "vacuumed"

frequently to prevent interference with normal motor ventilation and proper

operation of the centrifugally-operated starting switch.

TROUBLE

Excessive noise.

Motor fails to develop lull power. NOTE:

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

10% in voltage causes a reduction of 19% in

maximum power output of which the motor is

capable, and a reductior of 20% in voltage causes a reduction of 36% in maximum power output.)

PROBABLE CAUSE

1. Motor.

1.Circuit overloaded with lights, appliances and other motors.

2.Undersize wires or circuit too long.

3.General overloading of

power company facilities.

REMEDY

1, Have motor checked by qualified service

technician. Repair service is available at your nearest Sears store.

1.Do not use other appliances or motors on same circuit when using the saw.

2.Increase wire sizes, or reduce length of wiring. See "'Motor Specifications and Electrical

Requirements" section.

3.Request a voltage check from the power company.

1.Request voltage check from the power company. Check size of circuit wiring.

2.Have motor repaired or replaced.

3.Blow out sawdust from motor. Have motor repaired.

1.Feed work slower into blade.

2.Clean out sawdust to provide normal air circulation through motor. See "Maintenance and Lubrication" section.

1.Have switch replaced and request a voltage check from the power company.

2.Have capacitor tested and replace if defective.

3.Have wiring checked and repaired.

1.Have switch replaced.

2.Request voltage check from the power company.

3.Install proper size fuses or circuit breakers.
