Setting the accelerator lever angle, load sensor adjustment
1. Accelerator lever setting method
(1)Position the speed lever against the idle stopper bolt and fix.
(2)Screw in the accelerator lever stopper bolt (A) and back off the stopper bolt (A) from the position where the accelerator lever pin contacts the speed lever and set. (Gap: approx. 1 mm)
Tightening torque: 4.9~7 N.m {0.5~0.7 kgf.m}
2. Load sensor adjustment (See fig 1)
(1)Load sensor output measuring circuit
Apply DC5+-0.01V to the load sensor terminals and measure the output voltage.
(2)Load sensor output adjustment procedure
Hold the speed lever against the full side stopper bolt and fix. Adjust the load sensor output voltage to VF = 0.417+-0.1 V using the link (B) and then fix temporarily using nut (C).
Turn the speed lever from the idle side to the full side and confirm that output voltage VF = 0.417+-0.1 V is obtained. Confirm several times and then fix using nut (C).
Tightening torque: 3.4~4.9 N.m {0.35~0.5 kgf.m}
3. Setting the step motor's idle side stopper bolt
After adjustment in previous 1 and 2, position speed lever against idle stopper bolt and fix. Then, screw in stopper bolt G until step motor lever D's pin E contacts lever F. Back off 10+2 deg (approx. 3.5 mm) from this position and fix G. (See fig. 3)
4. Speed lever return confirmation
(1)Remove return spring (H) and confirm that the speed lever is returned to the idle position by the torsion spring.
(2)Reinstall the return spring (H) in its original position.

Set speed by turning adjusting screw
Adjust speed. If Ng exceeds TMI specifications, tighten the adjusting screw. If Ng is less than the specified value, loosen the adjusting screw.
Illustration 64 g02807957
Adjust the maximum-speed stopper bolt
Adjust the maximum-speed stopper bolt until the speed at the start of high-speed control is Nf.
Check that the no-load maximum speed is Ng (described in Step 1). Continue adjustment until the specified value is obtained.

Measuring control lever angle at the "full-speed" and "idling" positions.
Measuring the control lever angle at the "idling" and "full" positions.
If the angle is not as specified by TMI, replace the shifters shim. If the control lever is positioned toward the "full" position, replace the shifters shim with a thicker one. When control lever is toward the "idling" position, replace the shim with a thinner one.Check Starting Delivery

Adjusting screw for setting fuel flow
If delivery rate does not meet TMI specifications, remove cap (2), loosen lock nut, and adjust screw (3). Adjusting screw outward decreases fuel flow and inward increases fuel flow.
Install cap (2) and recheck delivery rate. Repeat Steps 2 through 6 until delivery rate is at specified value.Lockwiring Caps of Adjustment Screws
All adjustment stops (screws) that directly affect engine performance should be lockwired after adjustment. Do not readjust any stop without using the test stand can adversely affect the engine and engine performance.
