Combining the gearhead to the 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 confirm that no gaps remain between the
motor and gearhead.
An O-ring is attached to the flange 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.
Installing the round shaft type
Drill holes in the mounting plate, and secure the motor using the hexagonal socket head screws (not supplied) through four
mounting holes.
Install it so that no gaps remain between the motor mounting surface and mounting plate.
