MOTOR TROUBLE - SHOOTING CHART

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.

maximum power output of which the motor is

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

2.Undersize wires or circuit too long.

3.General overloading of power company's facilities, (In many sections of the country, demand for electrical power exceeds the capacity of existing

generating and distribution systems.)

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

3.Request a voltage check from the power company.

Motor starts slowly or fails to come up to full speed.

Motor stalls (resulting in blown fuses or tripped circuit breakers).

2. Improper cooling. (Air

circulation restricted through motor due to sawdust, etc.)

3. Saw blade has "heel".

1, Low Voltage will not trip starting switch.
