8-1
Turn the POWER switch OFF, then unplug
the motor unit connectors from the
motherboard. When you do this, be careful
not to bend the pins of the motherboard
connectors.
Variation:
The operations described from this point on are variations. If you
are interested, try them for yourself: however, they are not essential.
By changing the gears on the motor units, you can determine whether to prioritize
speed, or power.
8-2
Remove both motor boxes (including the
cables) from the frame. It is easier if
you remove the legs first.
8-3
Remove the screws and open the motor box.
8-4
Remove the motor switch form the gearbox
(below).
8-5
Using needle-nosed pliers or any other
suitable tool, remove the pinion gear from
the motor. As you do so, be careful not
to damage the teeth of the gear.
8-6
Select a pinion gear.
High-speed type (black): High speed, low
power. Low-speed, high-torque type (white):
Low speed, high power.
8-7
Press the selected pinion gear on to the
motor. Press firmly as far as it will go.
Pinion gear 1 High-
speed type (initial
setting)
Pinion gear 2 Low-
speed, high-torque type

Changing the Gears
8-8
Install the motor in the gearbox (below).
8-9
Install the switch in the gearbox (below).
Pass the cables from the motor and the
switch through the gap as shown in the
diagram below.
8-10
Change gear unit A (hold it so that you can
lift it from above).
If you are using pinion gear 1, use Gear
Unit A-1, and if you are using pinion
gear 2, use Gear Unit 1-2.
8-11
Secure the gearbox in position by fastening
the screws, and re-assemble the motor
unit. Fasten the screws firmly to eliminate
any gear between the upper and lower
parts of the gearbox. When you do this,
be careful that the cables pass correctly
through the gap, and are not caught
between the parts of the gearbox. Use
the same pinion gear, are gear unit A,
for both motor units.
8-12
Attach the motor units to the frame and
attach the connectors to the motherboard
explained on page 11. When you have done
this, the replacement of the gears is
complete.
