Figure 1 is only for reference. Lever shape, etc, may vary.
1. Minimum-maximum speed specification adjustment (when running)
(a) Without applying air to the air cylinder, loosen bolts (A) and (B).
(1)High speed return L setting
(a) In the speed range Nf~Nf - 300r/min, adjust using the speed adjusting bolt to determine the temporary beginning of high speed control speed.
(b) Determine the rack position in the vicinity of Rf using the full load lever.
(c) Increase speed and confirm return distance L.
(d) Adjust using the tension lever bolt to obtain L.
(2)Setting full load rack position Rf
(a) Move the load control lever to the full side.
(b) Adjust the full load adjusting bolt so that Rf can be obtained, then fix.
(3)Setting the beginning of high speed operation Nf
(a) Adjust using bolt (E) so that Nf can be obtained, and then fix.
(4)Idle control setting (Re, Ni, Rc)
(a) Set the speed at Ns + 200r/min and move the load control lever to the idle side.
(b) Fix the lever in the position where Re can be obtained.
(c) Next, decrease speed to Ni and screw in the idle spring.
(d) Adjust to obtain rack position Ri.
(e) Increase the speed and after confirming that the rack position is Re at Ns, set the speed at 0.
(f) Confirm protrusion position Rc at idle.
(5)Damper spring adjustment
(a) Increase speed and set the speed at the rack position Rd - 0.1 mm
(b) Set using the damper spring so that the rack position Rd can be obtained.
(c) When Rd is not specified, Rd = Ri - 0.5 mm.
(6)High speed droop confirmation
(a) Return the load control lever to the full load lever position.
(b) Increase the speed and confirm that Rf can be obtained at Nf r/min.
(c) Confirm that speed is Nh at rack position Rh.
2. Variable speed specification adjustment (at operation)
(a) Remove return spring (D).
(b) Apply air pressure of 245~294 kPa {2.5~3 kg/cm2} to the air cylinder.
(c) Perform the following adjustment in this condition.
(1)Setting full load rack position Rf'
(a) Pull the load lever to the idle side.
(b) Obtain rack position Rf' using the nut (C). (Pump speed is Nf'-50 r/min.)
(2)Setting full speed Nf'
(a) Adjust using bolt (B) so that Nf can be obtained, and then fix.
(3)Low speed side setting
(a) At 350r/min, set bolt (F) at beginning of governor operation position, then fix.
3. Bolt (A) adjustment
(1)Install return spring (D) and perform the adjustments below at air pressure 0.
(a) Set at speed Nf using bolt (E).
(b) Screw in bolt (A).
(c) Screw in 1 more turn from the speed lever contact position
(d) Fix bolt (A).
(e) At this time confirm that the air cylinder's shaft moves approximately 1 mm towards the governor.
4. Lever operation confirmation using the air cylinder
(1)Apply 588 kPa {6 kg/cm2} air pressure to the air cylinder.
(2)Confirm that the cylinder piston is moved 50 mm by the spring (D).
