(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).

Cold Weather Battery Maintenance
General Maintenance
1. After adding make-up water, charge the battery. The added water could dilute the electrolyte enough without charging to cause freezing and permanent damage to the battery.2. Keep the batteries fully charged either by operating the charging system or by using a battery charger.3. Keep the battery warm when not in use. In an unheated area, the heat from a lighted electric bulb is usually sufficient.
Use only a shop cord with a heavy wire guard around the light bulb.
Do not lay a lighted bulb directly on a battery case; the heat at point of contact could melt the battery case.Do not lay cloth or flammable material in contact with a lighted bulb; charring and/or fire could result.4. Use starting aids as instructed for starting the engine.5. Use booster batteries as required. Connect the batteries as instructed below.6. If a battery is not going to be used for a period of time, be sure the battery is fully charged while stored. Use a battery hydrometer to check the specific gravity of each cell, and use a battery charger to keep the battery charged. See the instructions below.Voltage Test (After Load)
A load test should be made on a battery that discharges very rapidly when in use. To do this apply a resistance of three times the ampere/hour rating of the battery across the battery main terminals. Allow the resistance to discharge the the battery for 15 seconds and immediately test the battery voltage. A 6 volt battery in good condition will test 4.5 volts; a 12 volt battery in good condition will test 9 volts and a 24 volt battery will test 18 volts.Starter
No periodic service is indicated for the electric starter brushes between general reconditioning periods. The brushes should only be inspected after removal of the starter from the engine and removal of the commutator end bearing frame. The electric starter commutator end and drive end bearings are equipped with wicks for lubrication purposes. The wicks should be saturated with oil whenever the electric starter is removed or disassembled.It is suggested that cleaning and reconditioning be entrusted to your authorized dealer.Pinion Clearance Adjustment
Whenever the solenoid is installed, the pinion clearance should be adjusted. The adjustment should be made with the starting motor removed.Bench test and adjust the pinion clearance at installation of solenoid as follows:
CIRCUIT FOR CHECKING AND ADJUSTING PINION CLEARANCE1. Install the solenoid without connector from the MOTOR terminal on solenoid to the motor.2. Connect a battery, of the same voltage as the solenoid, to the terminal marked SW.3. Connect the other side of battery to ground terminal or to solenoid frame.
ADJUSTING PINION CLEARANCE4. MOMENTARILY flash a jumper wire from the solenoid terminal marked MOTOR to the frame or ground terminal. The pinion will shift into cranking position and will remain there until the battery is disconnected.5. Push pinion towards commutator end to eliminate free movement.6. Pinion clearance should be .36 in. (9.14 mm).7. Adjust clearance by removing plug and turning shaft nut.
