Assembling the gearhead to the motor
1.
Keep the pilot sections of the motor and
gearhead in parallel, and assemble the
gearhead with the motor while slowly
rotating it clockwise/counterclockwise.
At this time, note so that the pinion of the
motor output shaft does not hit the side
panel or gears of the gearhead strongly.
Change the cable position to
one of three 90° directions.
2.
Check no gaps remain between the motor and gearhead, and tighten them with
hexagonal socket head screws (4 places).

Note
•
Do not forcibly assemble the motor and gearhead. Also, prevent metal
objects or foreign substances from entering in the gearhead. The pinion
of the motor output shaft or gear may be damaged, resulting in noise or
shorter service life.
•
Do not allow dust to attach to the pilot sections of the motor and
gearhead. Also, assemble the motor and gearhead carefully by not
pinching the O-ring at the motor pilot section. If the O-ring is crushed or
severed, grease may leak from the gearhead.
