2.
Using the pilot sections of the motor and gearhead as guides,
install the gearhead to the motor and tighten the hexagonal
socket head screws.
At this time, the motor cable position can be changed to a desired 90°
direction.
When installing the gearhead, 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 ange surface and
the end face of the gearhead’s pilot section.
Change the cable
position to a desired
90° direction.
Pilot section
Note
•
Do not forcibly assemble the motor and gearhead. Also, do not let metal objects or other foreign
matter enter the gearhead. The pinion or gear of the motor output shaft 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’s pilot section. If the O-ring
is crushed or severed, grease may leak from the gearhead.
•
The hexagonal socket head screws assembling the motor and gearhead are afxing the motor
and gearhead only temporarily. When installing the gearhead, be sure to use the supplied
hexagonal socket head screws (4 pcs.).
