Hardware Variations, Changing the Gears

HARDWARE VARIATIONS

Variation: The operations described from this point on are variations. If you are interested, try them for yourself: however, they are not essential.

Changing the Gears

By changing the gears on the motor units, you can determine whether to prioritize speed, or power.

8-8

Install the motor in the gearbox (below).

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.

(initial High-speed	speed, high torque
type setting)

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.

8-2

Remove both motor boxes (including the cables) from the frame. It is easier if you remove the legs first.

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.

8-9

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.

Gear unit A-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.

8-6

Select a pinion gear.

High-speed type (black): High speed, low power. Low-speed, high-torque type (white): Low speed, high power.

Change gear unit A (hold it so that you can lift it from above).

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.
