INSTALLATION, CONNECTION AND MAINTENANCE INSTRUCTIONS
FOR
CRAFTSMAN MOTOR - MODEL NO. 113.12171
EXTRA SAFETY PRECAUTIONS: Motor must be properly grounded. (See figure
4).
Do
not operate motor with key and key clip loose on shaft. Keep hands and clothing away
from moving parts. Mount shaft guard assembly over shaft extension not being used.
CHICAGO, IL 60684
This Craftsman Motor is of the capacitor start type
designed for use on a single-phase, 60-cycle, alternating-
current supply of 115 volts, with a simple means of
reversing the direction of rotation provided. The motor
may be operated in any position.
INSTALLING THE MOTOR
1. This motor was given a thorough electrical and
mechanical inspection before it was shipped from the
factory. In order to make sure that no damage has
occurred during shipment, the following check pro-
cedure should be made before mounting the motor in
the particular application for which it was purchased.
a. Remove key and key clip from shaft.
b. Rotate the shaft with the fingers to make sure it
turns freely and smoothly.
c. Clamp motor base to work bench or table. Insure
motor is properly grounded. Do not touch motor
while it is energized. Temporarily connect motor
to the proper voltage supply in accordance with
instructions under "Connecting the Motor". When
energized, the motor should operate with only a
small amount of electrical "hum" and very low
bearing noise.
d. Notice direction of shaft rotation to make sure it
is correct for the equipment to be driven. If direc-
tion of rotation is not correct, reverse rotation
as outlined in instructions listed under "Connect-
ing the Motor".
2. Disconnect the motor from temporary power source
and mount it in the application for which it was pur-
chased.
3. The motor should be installed in a location as cool
and dry as possible and should be protected against
excessive deposits of dust, dirt, and moisture. (See
figure 1 for mounting dimensions.) The motor must
not be confined in a small space that will restrict the
flow of cooling air over internal electrical windings.
4. Before tightening the motor mounting bolts, make
sure all four mounting points of the base are in con-
tact with the surface to which the motor is being
attached. If the motor base does not contact the
mounting surface properly, the base (or support) may
be warped or cracked when mounting bolts are
tightened.
5. Make sure all pulleys are tightened securely on their
shafts and correctly aligned. Proper pulley alignment
may be obtained by holding a straight edge across the
flat sides of the pulleys and adjusting to it. (See
figure 2.)
6. Adjust the belt tension so that pressure of fingers on
the belt will deflect it readily as shown in figure 3.
Excessive belt tension increases the load on the motor
and decreases bearing life. Loose belts reduce oper-
ating efficiency and shorten belt life.
7. After the motor base has been properly adjusted to
the mounting bracket, tighten all motor mounting
bolts securely.
