3.10 MAJOR SERVICE MANUAL

To obtain a service manual for the generator, contact the nearest Authorized Service Dealer. Make sure to identify the MODEL NUMBER and SERIES.

Recreational Vehicle Generator

4.Reconnect the battery. Observe battery polarity. Damage may occur if the battery is connected incorrectly.

5.Turn OFF all electrical loads. Add fuel if neces- sary and then start the engine.

3.11 EXERCISING THE GENERATOR

The manufacturer recommends that the generator be started and operated at least once every seven days. Let the unit run for at least 30 minutes to “exercise” the engine.

3.12 OUT OF SERVICE PROCEDURE

‹3.12.1 REMOVAL FROM SERVICE

If the generator cannot be exercised every seven days, and it is to be out of service longer than 30 days, pre- pare the generator for storage as follows:

1.Start the engine and let it warm up.

2.Close the fuel shutoff valve in the fuel supply line and allow the unit to shut down.

Note:

Using a fuel additive such as STA-BIL fuel stabi- lizer, or an equivalent, will prevent gum deposits from forming in the engine’s fuel system.

3.While the engine is still warm from running, drain the oil completely. Refill the crankcase with SAE 10W-30 oil having API classification “For Service SF.”

4.Attach a tag to the engine indicating the viscosity and classification of the oil in the crankcase.

5.Remove the spark plug and pour two or three tablespoons of clean, fresh engine oil into the spark plug threaded openings. Reinstall and tighten the spark plug.

6.Remove the battery and store it in a cool, dry room on a wooden board. Never store the battery on any concrete or earthen floor.

7.Clean and wipe the entire generator.

‹3.12.2 RETURN TO SERVICE

To return the unit to service after storage, proceed as follows:

1.Check the tag on the engine for oil viscosity and classification. Verify that the correct recommend- ed oil is used in the engine (see Section 1.5.4). If necessary, drain and refill with the proper oil.

2.Check the state of the battery. Fill all cells of unsealed batteries to the proper level with dis- tilled water. DO NOT USE TAP WATER IN THE BATTERY. Recharge the battery to 100 percent state of charge, or, if defective, replace the battery.

3.Clean and wipe the entire generator.

6.Allow the unit to run for several minutes to warm up.

7.Apply electrical loads to at least 50 percent of the unit’s rated wattage capacity.

8.When the engine is thoroughly warmed up, shut it down.

9.The generator is now ready for service.

3.13 ADJUSTING VALVE CLEARANCE

After the first 50 hours of operation, adjust the valve clearance in the engine.

When adjusting valve clearance, the engine should be at room temperature and the piston should be at Top Dead Center (TDC) of its compression stroke (both valves closed). Correct clearance is 0.001-0.003 inch

(0.03-0.07mm). Adjust valve clearance as follows:

1.Loosen the rocker arm jam nut. Use an allen wrench to turn the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge (Figure 3.7).
