1. Gearshift lever
This lever (1) changes the speed range of the transmission.
Manual shift
This machine has a 4-FORWARD, 4-REVERSE speed trans-
mission.
Place the gearshift lever in a suitable position to obtain the
desired speed range.
z 1st and 2nd speeds are used for working.
z 3rd and 4th speeds are used for traveling.
However, when the gearshift lever stopper is being used, it is
impossible to shift to 3rd or 4th. Disengage the gearshift lever
stopper before trying to shift gear.
Position (a): 1st
Position (b): 2nd
Position (c): 3rd
Position (d): 4th
REMARK
The length of the lever can be adjusted to 3 stages (positions
(A), (B), (C)). To adjust the length, remove the screw (E) at the
bottom of the lever knob (D), slide the knob to the desired posi-
tion, then tighten the screw (E) again.
(The lever is installed to position (B) when it is shipped from the
factory.)
Automatic shift
Automatic gear shifting can be carried out in the 2nd through 4th
speed range of the four forward and reverse speeds depending
on the travel conditions.
Position (a): 1st
Position (b): 2nd
Position (c): 3rd
Position (d): 4th
The range of speeds during automatic gear shifting is deter-
mined by the position of the gearshift lever as shown in the chart
on the right.
