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" frequentiy to prevent =

interference with normal motor ventilation and proper operation of the centrifugally-

operated starting switch. , '

TROUBLE PROBABLE CAUSE REMEDY

Excessive noise. 1, Motor,

Motor fails to develop

full power, NOTE:

LOW VOLTAGE: (Power

output of motor

decreases rapidly with

decrease in voffage 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 reduction

of 20% in voltage causes

a reduction of 36% in

maximum power output.)

Motor starts slowly

or fails to come up

ito full speed,

Motor overheats.

Starting switch in motor

wilt not operate.

Motor stalls (resulting

in blown fuses or

tripped circuit breakers),

Frequent opening of

fuses or circuit

breakers.

1. Circuit overloaded with

lights, appliances and other

motors.

2r Undersize wires or circuit

too long.

3. General overloading of

power company facilities.

!. Low voltage will not trip

relay,

2. Windings burned outor

open.

3. Starting relay not operating.

!. Motor overloaded.

2. Improper cooling. (Air

circulation restricted

through motor due to

sawdust, accumulating

inside of motor).

1. Burned switch contacts

(due to extended hold-in

periods caused by low line

voltage, etc.).

2. Shorted capacitor.

3. Loose =or broken

connections.

1. Starting switch not

operating.

2. Voltage too tow to permit:

motor to reach operating

speed!

3. Fuses or circuit breakers

do not have sufficient

capacity.

1. Motor overloaded.

2. Fuses or circuit breakers

do not have sufficient

capacity.

3, Startring switch not

operating (motor does not

reach speed).

1, Have motor checked by qualified service technician.

Repair service is available at your nearest Sears store.

t. Do not use Other appliances or motors on same circuit

when using the jointer.

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.

2. Have motor repaired or replaced.

3. Have relay replaced.

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.

1. Feed work slower.

2. install proper size fuses or circuit breakers.

3. Have switch replaced.
