Installing the combination type
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.

Removing/Installing the gearhead
To replace the gearhead or change the cable outlet direction, remove the
screws assembling the gearhead. The gearhead can be removed and the motor
cable position changed to a desired 90° direction.
1. Remove the hexagonal socket head screws (2 pcs.) assembling the motor
and gearhead and detach the motor from the gearhead.
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.
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.

Combination type hollow shaft at gearhead
A combination type hollow shaft at gearhead can be installed by using either
its front or rear side as the mounting surface. Install the included hexagonal
socket head screw set in the four mounting holes you drilled and tighten the
nuts until no gaps remain between the motor and mounting plate.
Since hexagonal nuts are not included with the product, provide them
separately or drill tapped holes in the mounting plate.
Also, attach the included safety cover to the hollow output shaft on the end
opposite from the one where the load shaft is installed.

Removing/Installing the gearhead
To replace the gearhead or change the cable outlet direction, remove the
screws assembling the gearhead. The gearhead can be removed and the motor
cable position changed to one of three 90° directions.
Note that the motor cable cannot be positioned in the direction where the
cable faces the gearhead output shaft.
1. Remove the hexagonal socket head screws (4 pcs.) attaching the gearhead
and motor and detach the motor from the gearhead.
2. Using the pilot sections of the motor and gearhead as guides, install the
motor to the gearhead and tighten the hexagonal socket head screws.
Install the motor carefully to prevent the pinion of the motor output shaft
from contacting the casing or gear of the gearhead.
