0000001801 MOTOR LEVER ADJUSTMENT
Motor lever adjustment
With the control lever contacting the idle stopper bolt, adjust the length of the rod so that the stepping motor bracket and the motor lever position alignment stamping are aligned.
Nut tightening torque: T1
After confirming the specified torque, apply yellow paint to the end of the rod and the nut.
C = nut
D = rod
E = yellow paint
F = stepping motor bracket
G = end of rod
H = angle alignment stamping

0000001901 MICROSWITCH ADJUSTMENT
Microswitch adjustment
1. Adjusting plate selection
Select a plate from the lever angle beta in the table and then fix the lever.
2. Full position adjustment
(1)Insert a shim (L2) between the control lever and the full stopper bolt.
(2)Move the microswitch in the direction of the arrow and confirm that it turns ON.
(3)Screw in bolt 1 and fix the microswitch when it turns from ON to OFF.
3. Idle position confirmation
(1)With a shim L2 = L3 inserted between the control lever and the idle stopper bolt, confirm that the microswitch is ON.
If it is OFF, exchange the installed plate with a plate with a higher number and readjust from full position in 2.
(2)Then insert a shim L2 = L4 and confirm that the microswitch is OFF.
If it is ON, exchange the installed plate with a plate with a lower number and readjust from full position in 2.
(3)Remove bolt 1 after confirming that On/Off positions at (1) and (2) are within the specifications
After confirming the specified torque of the bolt shown in figure 3, apply yellow paint.
Caution 1:Use the unit to confirm (1) and (2) above and insert a shim L5 when the lever is moved from idle in the full direction.
When the number of steps exceeds S1 in Caution (1) and (2) in the ON and OFF positions at clearance L2 = L6, install a plate with a number 2 ranks up or down from the plate that is already installed.
Caution 3: When applying yellow paint to the cam plate, do not apply paint to the cam face or the outside of the microswitch roller.
