TROUBLE SHOOTING

-- MOTOR (Continued)

TROUBLE

Motor starts slowly

or fails to come up

to full speed.

Motor overheats.

Starting relay in motor will not

operate.

Motor stalls

(resulting in blown

fuses or tripped

circuit breakers)°

Frequent opening of

fuses or circuit

breakers.

 

 

PROBABLE

CAUSE

1, Low voltage will not

 

trip

relay,,

 

 

2,

Windings

burned out

 

or

open.

 

 

 

3.

Starting

relay

not

 

 

operating.

 

 

 

t,

Motor

overloaded

 

2._ Improper

cooling,

(Air

 

circulation

restricted

 

 

through

motor

due

to

 

sawdust,

accumulating

 

inside of

saw).

 

 

t. Burned relay contacts (due to extended hold-in periods caused

by low line voltage, etc.,)

2 Shorted capacitor (when equipped)

3, Loose or broken connections.

t. Starting relay not operating,,

2.Voltage too low to permit motor to reach operating

speed

3 Fuses or circuit breakers do not have sufficient

capacity.

1, Motor overloaded,

2 Fuses or clrcuit breakers do not have sufficient capacity,

3_ Starting relay not operating (motor does not reach speed),,

REMEDY

ill i

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 motorr

See "Maintenance and Lubrication" section.

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

2.Test capacitor and replace if defectlve,

3o Have wiring checked and repaired

1, Have relay replaced,

2, Request voltage check from the power company,

3, Install proper size fuses or circuit breakers,

1 Feed work slower into blade

2, Install proper slze fuses or circuit breakers,

3Have relay replaced
