Section 4 — Maintenance

Air-cooled 7 kW, 12 kW and 15 kW Generators

The exhaust from this product gets extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system.

The maximum ambient temperature for the generator is 48.9° C (104° F).

4.10 ATTENTION AFTER SUBMERSION

If the generator has been submerged in water, it MUST NOT be started and operated. Following any submersion in water, have an Authorized Dealer thoroughly clean and dry the generator.

4.11 CORROSION PROTECTION

Periodically wash and wax the enclosure using automo- tive type products. Frequent washing is recommended in salt water/coastal areas. Spray engine linkages with a light oil such as WD-40.

4.12 OUT OF SERVICE PROCEDURE

‹4.12.1 REMOVAL FROM SERVICE

If the generator cannot be exercised every seven days, and it is to be out of service longer than 90 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.

3.Once the unit has shut down, it will signal a low oil fault.

4.Set the AUTO/OFF/MANUAL switch to OFF and turn off the utility power to the transfer switch.

5.While the engine is still warm from running, drain the oil completely. Refill the crankcase with oil. See ”Engine Oil Recommendations,” Section 4.3.1.

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

7.Remove the spark plug(s) and spray fogging agent into the spark plug(s) threaded openings. Reinstall and tighten the spark plug(s).

8.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.

9.Clean and wipe the entire generator.

‹4.12.2 RETURN TO SERVICE

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

1.Set the generator’s main circuit breaker to its OFF (or open) position.

2.Verify that utility power is turned off and that the AUTO/OFF/MANUAL switch is set to OFF.

3.Check the tag on the engine for oil viscosity and classification. Verify that the correct recommended oil is used in the engine (see Section 4.3.1). If neces- sary, drain and refill with the proper oil.

4.Check the state of the battery. Fill all cells of unsealed batteries to the proper level with distilled water. DO NOT USE TAP WATER IN THE BATTERY. Recharge the battery to 100 percent state of charge, or, if defective, replace the battery. See “Specifications,” Section 1.5, for type and size.

5.Clean and wipe the entire generator.

6.Remove the 5A fuse from the generator control panel.

7.Reconnect the battery. Observe battery polarity. Damage may occur if the battery is connected incor- rectly. Replace the 5A fuse in the generator control panel.

8.Open the fuel shutoff valve.

9.Start the unit by moving the AUTO/OFF/MANUAL switch to MANUAL. Allow the unit to warm up thor- oughly.

10.Stop the unit and set the AUTO/OFF/MANUAL switch to AUTO. Set the generator’s main circuit breaker to its ON (or closed) position.

11.Turn on the utility power to the transfer switch.

12.The generator is now ready for service.

NOTE:

If the battery was dead or disconnected, the exercise timer must be reset.
