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 simpie means of reversing the
direction of rotation provided, The motor may be operated
in any position.
MOUNTING
iNSTRUCTiONS
i i 3.i:2260
7. After the motor base has been properly adiusted to
the mounting bracket, tighten al_ motor mounting bobs
secure_y_
NOTE: in order to prevent accumulation of
static electric charges due to belt friction, the
motor frame or base should be grounded to
a water or steam pipe. A metallic connection
should also be provided between the motor
and the device being driven.
THE MOTOR
1. This motor was given a thorough electrical and mecham
ical inspection before it was shipped from the factory.
in order to make sure that no damage has occurred
during shipment, the following check procedure should
be made before mounting the motor in the particular
application for which it was purchased.
a, Rotate the shaft with the fingers to make sure it turns
freely and smoothly.
b_ Clamp motor base to work bench or table and remove
key from shaft. Connect motor to the proper voltage
supply temporarily in accordance with instructions
under "Connecting
the Motor". When energized,
the motor shoWd operate with only a smaii amount
of electrical "hum" and very low bearing noise.
c. Notice direction of shaft rotation to make sure it is
correct for the equipment to be driven. _f direction
of rotation is not correct, reverse rotation as outiined
in instructions listed under "'Connecting
the Motor "°.
Reoinstall the key in motor shaft.
& included with this motor is a new molded shaft guard
that can be easily twisted into place over the unused
shaft extension as an extra: safety feature.
CONNECTING
THE MOTOR
CAUTION: This motor wili be damaged if
connected to a current source other than 60_
cycle affernating<urrent
(ac).
1. The motor must be operated on ! 15-voff, 60-cycle a<
power when connected as outlined in instructions that
follow. Motor wires are color coded to make connec_
tions easy to accomplish.
2. A 484rich, 3<onductor (center ground wire) cord and
plug assembly is attached at the factory, with the two
power leads connected to the quick connect tabs adiacent to termina_ posts "T_ " and _'T¢" . (See figure 40 In
event this cord is removed and the motor wked for a
permanent installation,
connect one power lead to
terminal "T_" (or quick connect tab adiacent to it), Connect the other power _ead to termina_ "T4" {or quick
connect tab adiacent to it)
2. Disconnect the motor from temporary power source and
mount it in the application for which it was purchased.
3. The motor should be installed _n a location as cool and
dry as possible and should be protected against excessive deposits of dust and dirt. (See figure I for mounting
dimensions.) The motor must not be confined in a small
space that will restrict the flow of cooling air over
internal elec:trlcal windings.
3. Connections between motor and power s_urce should
be made through o switch and fuse block. Use a 20ampere fuse for ! 15-voffs. }:uses of the delayed_acfion
type, such as "Fustat" or "Fusetron" are recommended,
as they are designed for best motor protection.
4. The wire sizes listed beiow are recommended for circu{t
connections between motor and power supply, or extem
SiGn cords (_f used/.
4. Before tightening the motor mounting bohs_ make sure
at_ four mounting points of the base are in contact 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.
Length
5. Make sure all puiieys are tightened securely on their
shafts and correctly aligned. Proper pulley a_gnment
may be obtained by holding a straight edge across the
flat sidesof: the pulteys and adiusting to it. (See figure 2.)

Most motor troubles may be traced to .loose or incorrect
connections; to overloading; to reduced input voltage
which results when small size wires are used in the supply
circuit, or when the supply circuit is very long. Always
check connections, load and supply circuit when the
motor foils to perform satisfactorily. Although the motor
is designed for operation on voltage and frequency
specified on motor nameplate, normal loads will be
handled safely on voltages not more than l@_'_ove
or below the nameplate voltage. Heavy loads, however, require that voltage at motor terminals be not
less than the voltage specified on nameplate.
6_
Common Causes of Low Voltage Are:
o. Overloadlng
of house or shop circuits with lights,
e_ectricol appilances or other motors.

5. The Black and Red motor leads are connected to the
quick connect tabs on terminal board. (See figure 4.)
NOTE: To reverse direction of rotation, inter°
change position of B!ock and Red motor leads.
WARNING:
Do not change any of these connections with current on.
6. This motor is equipped with a 3-prong connector plug
(Underwriters ' Laboratory approved) as a safety measure. The longest of the three prongs is connected to the
motor housing through the power cord. When the p_ug
is inserted into a properly grounded receptacle, the
user is protected from electrical shock, should the motor
insulation fail for any reason. When using on extension
cord, make sure it is also a 3-wire cable.
CAUTION: Many existing receptacle boxes do
not have provision for 3oprong plugs and for
this reason an adapter is included with the
motor. (This adapter is not used in Canada.) To
use the adapter, connect the grounding lead to
the box before operating motor (See figure 5).

2. Re-Jubrlcate motor bearings occasionally at the oil hole
located near the rap of the hub on each end shield, (See
figure 7.1 Be sure to wipe off dirt or grit if present

GUARANTEE
This Craftsman Motor was thoroughly
inspected and
tested before shipment. Should it foil due to faulty material
or workmanship, we will repair or replace it, at our option,
free of charge if returned to your Sears retail or mail-order
store wlthln one year from date of purchase. This guarantee is void if the motor has been tampered with, misused
or abused, or if either end shield has been removed in the
process of servicing by anyone other than an authorized
serv :e station. External parts such as the terminal cover
may be removed or replaced without voiding the guarantee.
3. If disassembly of the motor is necessary, it should be
returned to your nearest Sears retail or mail-order store
in order to prevent voiding the guarantee.

7, Some Effects of Low Voltage Are:
a. Motor fails to develop full power. (The power output of motor decreases rapidly with decrease in
voltage 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,
while a reduction of 20% in voltage causes a reduction of 36% 'n maximum power output.)
b. Motor starts slowly or fails to come up to full speed.
7. The motor may be operated with a reversing switch
(9M2982 in catalog), provided connections are made as
shown in figure 6. The motor must come to a complete
stop before reversing can be accomplished. If motor
rotation does not correspond to switch notations, interchange switch leads 2 and 4_
