OPERATION OPERATION
2. Switch over gear shift lever (2) to F (FORWARD) or R
(REVERSE) and set it to the 1st or 2nd speed.
3. Return brake pedal (1) back and depress accelerator pedal (3).
The machine starts.
REMARK
If carrying out a direction switching operation during travels, the gear speed probably shift down sequentially
before the directional change, for the protection of the passenger and machine. This is not abnormal.
Although, for safety, it is not possible to complete the direction change until the travel speed slows down to 4 km/h
(2.5 MPH) or lower, it is not abnormal. If reducing the travel speed down to 4 km/h (2.5 MPH) or lower by using
the brake during the direction switching operation, the direction changes automatically.
