Note Do not apply excessive force onto the output shaft of the gearhead
using a hammer or other tools. Doing so may cause damage to the
output shaft or bearings.
When using the output shaft end tapped hole of a gearhead
Use a tapped hole provided at the end of
the output shaft as an auxiliary means for
preventing the transfer mechanism from

Tightening torque: 0.6 N·m (5.3 lb-in)
Illustration shows the view from motor case side.
 Installing a gearhead to a motor
Using the pilot sections of the motor and gearhead as guides, slowly rotate it
clockwise/counterclockwise to prevent the pinion of the motor output shaft from
contacting the side panel or gear of the gearhead.
Also conrm that no gaps remain
between the motor and gearhead.
An O-ring is attached to the ange of
the motor. Do not pinch the O-ring when
assembling the motor and gearhead.
Pinching the O-ring causes a grease leak
from the gearhead.

Note Do not forcibly assemble the motor and gearhead. Also, do not let
metal objects or other foreign matters enter the gearhead. The pinion
or gear of the motor output shaft may be damaged, resulting in noise
or shorter service life.
Connection and operation
 Insulate the connecting part of the motor lead wires and power supply.
 Ground the motor using a Protective Earth Terminal.
Note Make sure that the motor case temperature does not exceed 90 °C
(194 °F) when operating the motor. Operation exceeding case
temperature 90 °C (194 °F) may signicantly deteriorate the coils
and ball bearings of the motor and shorten the motor's life span.
Motor case temperature can be measured by xing a thermometer
on the motor surface. It can also be measured using thermo tape or a
thermocouple.
