10. Other precautions on reassembly

After completing reassembly, set the storage battery and check for operation.
(1) Check the rotating direction of Guide Sleeve (A)

[6]

Press the (R) side of the Switch (W/Lock)

[41]

to check that Guide Sleeve (A)

[6]

rotates clockwise as

viewed from behind.

(2) Check for proper operation of the Shift Knob

[38]

Check that the speed properly changes between high and low by shifting the Shift Knob

[38]

. If the

speed does not change properly or moderately, correctly remount the improperly mounted Shift Knob

[38]

according to step “5. Reassembly of the drive unit (3).”

(3) Check that the LED goes on and off by pushing the Button

[44]

. (Although the LED cannot react when

turned on/off too quickly, this is no failure.)

(4) Check for flexible change of the handle between the L-shape and straight shape.
