Procedures

Engine Speed / Governor Adjustment adjustment

Back off the high speed stop screw.
Screw in the low speed adjusting screw until the frequency meter reads 60 Hz (generator on load).
Turn in the high speed adjusting screw until it bottoms; secure the locknuts.
Adjust governor sensitivity (droop) with the external knurled knob at rear of injector pump housing.

Governor Sensitivity (Droop) Adjustment adjustment

Rotate the external knurled knob at the rear of the injector pump housing.
Turning inward (clockwise) shortens the governor control spring, making it less sensitive and increasing speed droop.
Turning outward (counterclockwise) has the opposite effect.

Governor Speed Adjustment adjustment

Back off the high speed stop screw.
Screw in the low speed adjusting screw until the generator output frequency meter reads 60 Hz (generator on load).
Turn in the high speed adjusting screw until it bottoms.
Secure the locknuts.

Control Box Connections (Generator Voltage Reconnection) installation

⚠ Proceding instructions do not apply to models with a 347/600 voltage (designated 9X) or a 120/240 voltage (designated 3R); these connections are made at the factory.

Factory ships these 12 lead generators with load connection wires not connected together; wires T1 through T12 must be brought together before making load connections.
Remove either right, left or top panel from control box.
Connect wires together as shown on panel and in Figure 13 according to voltage desired.
Open hinged control panel doors. Connect lead from terminal 63 to correct terminal (H2, H3, H4, H5 or H6) for voltage desired.
Close front panel and secure with 1/4 turn fasteners.
Connect load wires to generator leads.

Control Box Load Connections (12-lead) installation

⚠ Instructions do not apply to 347/600 (9X) or 120/240 (3R) models; those connections are made at the factory.

Remove either right, left or top panel from control box.
Connect wires T1 through T12 together as shown on panel and Figure 13 for voltage desired.
Open hinged control panel doors. Connect lead from terminal 63 to correct terminal H2, H3, H4, H5 or H6.
Close front panel and secure with 1/4 turn fasteners.
Connect load wires to generator leads.

Battery Electrolyte Dilution for Hot Locations maintenance

⚠ Avoid skin or clothing contact with electrolyte.

Tools: hydrometer, filler bulb

Fully charge the battery.
With battery still on charge, draw off electrolyte above the plates in each cell (do not pour off).
Refill each cell with distilled water to normal level.
Continue charging for 1 hour at a 4 to 6 hour rate.
Test each cell; repeat steps 2-4 until specific gravity is 1.225.

Battery Service and Charging maintenance

⚠ Do not smoke while servicing batteries; lead acid batteries give off explosive gases while being charged.

Tools: hydrometer

Verify cable connections are secure; coat connections with petroleum-based or non-conductive grease.
Check electrolyte level to split ring mark.
Measure specific gravity; should be 1.280 at 80°F.
If distilled water was added or SG is less than 1.280, place batteries on charge until reading reached; do not overcharge.

Battery Servicing maintenance

⚠ Do not smoke while servicing batteries; lead acid batteries give off explosive gases while being charged.

Check the condition of the starting batteries at least every two weeks.
See that connections are clean and tight; coat with non-conductive grease.
Keep electrolyte at the proper level above the plates by adding distilled water.
Check specific gravity; recharge if below 1.260.

Dilute Battery Electrolyte for Hot Locations maintenance

⚠ Do not attempt to pour off electrolyte; avoid skin or clothing contact.

Tools: hydrometer, filler bulb

Fully charge the battery.
With the battery still on charge, draw off the electrolyte above the plates in each cell using a hydrometer or filler bulb.
Refill each cell with distilled water to normal level.
Continue charging for 1 hour at 4 to 6 amperes.
Test each cell; if specific gravity is still above 1.225, repeat steps 2, 3 and 4 until reduced to 1.225.

Out-of-Service Protection (over 30 days) maintenance

Run set until thoroughly warm.
Drain oil from oil base while still warm; refill and attach warning tag stating oil viscosity used.
Remove each injector; pour 1 ounce (two tablespoons) rust inhibitor or SAE #10 oil into each cylinder.
Crank engine over several times; install injectors.
Service air cleaner.
Clean throttle linkage and protect with a clean cloth.
Plug exhaust outlets to prevent moisture, bugs and dirt.
Wipe entire unit; coat rust-susceptible parts with light film of grease or oil.
Disconnect battery and follow standard battery storage procedure.
Provide a suitable cover for the entire unit.

Priming Fuel System maintenance

⚠ If the primer lever will not pump and no resistance is felt at upper end of stroke, turn engine over with starter to change position of fuel pump drive lobe on camshaft.

Verify all connections in the fuel system are secure and no leaks exist.
Loosen bleed plug on top of fuel filter.
Pump primer lever until a solid stream of fuel, free of air bubbles, flows from bleed plug.
Secure bleed plug.
Loosen inlet fuel line on injector pump.
Operate primer lever on fuel transfer pump until a solid stream of fuel, free of air bubbles, flows from inlet line opening.
Secure injector pump fuel inlet line.
Leave fuel transfer pump priming lever at lowest point of stroke.

Tank Heater Annual Service maintenance

⚠ When reassembling threaded aluminum parts, be sure to use anti-seize compound.

Remove head and valve assembly.
Clean foreign matter out of the tank.
Remove element and scrape off scale accumulated on the sheathing.
