Air-cooled 8.5 kW Generator

amps for 8.5 kW at -17.8º C (0º F) minimum. When using a maintenance-free battery, it is not necessary to check the specific gravity or electrolyte level. Have these procedures performed at the intervals specified in the “Service Schedule.” A negative ground system is used. Battery connections are shown on the wiring diagrams. Make sure the battery is correctly connect- ed and terminals are tight. Observe battery polarity when connecting the battery to the generator set.

Be sure the Auto/Off/Manual switch is set to ! the OFF position before connecting the battery

cables. If the switch is set to AUTO or MANUAL, the generator can crank and start as soon as the battery cables are connected.

Be sure the utility power supply is turned off, or sparking may occur at the battery posts as you attach the cables and cause an explosion.

DANGER

Do not dispose of the battery in a fire. The battery is capable of exploding.

A battery presents a risk of electrical shock and high short circuit current. The following precautions are to be observed when working on batteries:

Remove watches, rings or other metal objects;

Use tools with insulated handles;

Wear rubber gloves and boots;

Do not lay tools or metal parts on top of the battery; and

Disconnect charging source prior to connecting or dis- connecting battery terminals.

Do not open or mutilate the battery. Released

!electrolyte has been known to be harmful to the skin and eyes, and to be toxic.

The electrolyte is a dilute sulfuric acid that is

!harmful to the skin and eyes. It is electrically conductive and corrosive. The following procedures are to be observed:

Wear full eye protection and protective clothing;

Where electrolyte contacts the skin, wash it off immediately with water;

Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek medical attention; and

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) or 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.

Lead-acid batteries present a risk of fire because they generate hydrogen gas. The following procedures are to be followed:

DO NOT SMOKE when near the battery;

DO NOT cause flame or spark in battery area; and

Discharge static electricity from your body before touching the battery by first touching a grounded metal surface.

2.1BEFORE INITIAL START-UP

Before starting, complete the following:

1.Set the generator's Auto/Off/Manual switch to the OFF position.

2.Turn OFF the utility power supply to the transfer switch using the means provided (such as the utility main line circuit breaker).

3.Turn OFF all loads connected to the tranfer switch terminals T1 and T2.

4.Check the engine crankcase oil level and, if nec- essary, fill to the dipstick FULL mark with the recommended oil. Do not fill above the FULL mark.

5.Check the fuel supply. Gaseous fuel lines must have been properly purged and leak tested in accordance with applicable fuel-gas codes. All fuel shutoff valves in the fuel supply lines must be open.

Never operate the engine with the oil level

!below the “Add” mark on the dipstick. Doing this could damage the engine.

2.2CHECK TRANSFER SWITCH

OPERATION

Refer to Section 3.5 (Page 13), of the owner’s manual for manual operation procedures.

Do not attempt manual transfer switch opera- tion until all power voltage supplies to the transfer switch have been positively turned off. Failure to turn off all power voltage supplies will result in extremely hazardous and possibly fatal electrical shock.

2.3ELECTRICAL CHECKS

Complete electrical checks as follows:

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