QUIETPACT™ 65D Recreational Vehicle Generator

•Immediately wash with water all skin areas that come into contact with the electrolyte.

•If the electrolyte contacts the eyes, immediately flush eyes thoroughly with water, and seek med- ical attention.

•Spilled electrolyte is to be washed down with an acid-neutralizing agent. A common practice is to use a solution of 1 pound (500 grams) bicarbonate of soda to 1 gallon (4 liters) of water. The bicar- bonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried.

Do not use any chromate base rust inhibitor with ethylene glycol base antifreeze; other- wise, chromium hydroxide (“green slime”) will form and cause overheating. Engines that have been operated with a chromate base rust inhibitor must be chemically cleaned before adding ethylene glycol base antifreeze. Using any high-silicate antifreeze boosters or addi- tives will also cause overheating. We also rec- ommend that you DO NOT use any soluble oil inhibitor for this equipment.

3.7COOLING SYSTEM

Air intake and outlet openings in the generator com- partment must be open and unobstructed for contin- ued proper operation. Avoid obstructions, such as, high grass, weeds, brush, leaves, and snow.

Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down.

3.8ENGINE COOLANT

Check the coolant level in the coolant recovery tank at least once daily or prior to use. Add the recom- mended coolant mixture (see Section 1.5.4, Page 6), as necessary; the tank should be kept within the lev- els indicated on the adjacent decal. If desired, you may add a high-quality rust inhibitor to the recom- mended 50-50 coolant mixture. If added consistently, the recommended mixture will protect the unit against freezing temperatures.

Periodically remove the radiator pressure cap, locat- ed behind the access cover above the user control panel, to make sure the coolant recovery system is functioning properly. Coolant should be at the bottom of the radiator filler neck. If the coolant level is low, inspect the gasket in the radiator pressure cap. Replace the cap, if necessary. To have the pressure cap tested, contact a Generac Authorized Service Dealer. Inspect both the cooling system and coolant recovery system for leaks.

Do not remove the radiator pressure cap while the engine is hot; otherwise, serious burns from boiling liquid or steam could result.

Ethylene glycol base antifreeze is poisonous. Do not use your mouth to siphon coolant from the radiator, recovery bottle, or any container. Wash your hands thoroughly after handling. Never store used antifreeze in an open contain- er because animals are attracted to the smell and taste of antifreeze, even though it is poiso- nous to them.

3.9MAJOR SERVICE MANUAL

To obtain a service manual for your generator, con- tact Generac or your nearest Generac Authorized Service Dealer. Make sure to identify your MODEL NUMBER and SERIES.

3.10 DRIVE BELT

The engine drives the generator rotor by means of a pulley and drive belt arrangement. Drive belt tension was properly adjusted before the unit was shipped from the factory. If you suspect that drive belt tension is incorrect, contact a Generac Authorized Service Dealer.

3.11 EXERCISING THE GENERATOR

Generac recommends that you start and operate the generator at least once every seven days. Let the unit run for at least 30 minutes to “exercise” the engine. If you cannot exercise the generator every seven days, and it is to be out of service longer than 30 days, see Section 3.12.

3.12 OUT-OF-SERVICE PROCEDURE

◆3.12.1 REMOVAL FROM SERVICE

Prepare the generator for storage as follows:

1.Start the engine and let it run until it is thor- oughly warmed up (at least five minutes), then shut off the engine.

2.While the engine is still warm from running, drain the oil completely (see Section 3.2, Page 12). Refill the crankcase with the recommended oil (see Section 1.5.3, Page 6).

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

4.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.

5.Clean and wipe the entire generator.
