Trouble Possible Cause
Remedy
BAD SPARKING AT CON-
Open-circuited condenser.
Disconnect one yellow condenser lead and
TACT POINTS OR
turn switch knob to the No. I position. If
BURNED CONTACTS
a very faint spark ca n be seen when the
lead is touched to the other three leads
when the connection is made or broken,
the condenser is not open. If the con-
denser is in good condition, a noticeable
decrease in sparking is apparent at the
contact points. Replace a fa ulty co n-
denser.
Faulty resistor. Turn the switch knob to high speed and
break the circuit through the contacts
by lifting the inverted "T" shaped part of
the spring on which the contacts are
mounted. If the mixer comes to a full
stop, the resistor is faulty and should
be replaced.
BAD SPARKING AT
Worn motor brushes. Remove brushes and check that they are
MOTOR BRUSHES
not worn to less than 5/ 16 inch. Replace
with new brushes if excessively worn.
(Grade F-6)
Rough commutator. Remove the trim strip and hold a narrow
piece of fine sandpaper against the com-
mutator as the motor is running. If th e
commutator cannot be smoothed down in
this manner, remove the armature and
turn it down in a lathe.
Faulty armature or shorted motor field . Disassemble and check motor.
