Introduction

The servicing of marine engines and generator sets presents unique problems. In many cases, boats cannot be moved to a repair facility. Marine engines cannot be compared to the servicing of automobiles, trucks, or even farm equipment. Failures often occur in remote areas far from competent assistance. Marine engines are taxed far more severely than auto or truck engines; therefore, maintenance schedules must

be adhered to more strictly. Failures begin with minor problems that are overlooked and become ampliﬁ ed when not corrected during routine main- tenance. As operator, it is your obligation to learn about your equipment and its proper maintenance. This is not a comprehensive technical service manual. Nor will it make the reader into an expert mechanic. Its aim is to aid you in maintaining your unit properly.

Warranty

A warranty registration certiﬁ cate is supplied with your set. It entitles the original purchaser of our equipment to a warranty covering material or assembly faults. The extent of coverage is described in the Limited Warranty Statement. We recommend that you study the statement carefully.

CAUTION: Accident reports show that careless use of engines causes a high percentage of accidents. You can avoid accidents by observing these safety rules. Study these rules carefully and enforce them on the job.

• Never leave engine without proper security.

• Turn the coolant tank cap slowly to relieve pressure before removing. Add coolant only when the engine is stopped and cool.

• Mount a ﬁ re extinguisher near engine.

• Always disconnect the battery ground strap before making adjustments.

• Operate engines in properly ventilated areas.

• Keep trash and other objects away from engine.

• Escaping ﬂ uids under pressure can penetrate your skin. Use a piece of cardboard or wood, not your hands, to search for leaks.

• Avoid wearing loose clothing without a belt when working around engines.

NOTE: If the warranty is to apply, the servicing instructions outlined in this manual must be followed. If further information is needed, please contact an authorized dealer or the factory.

Safety Rules

• Use caution in handling fuel. Never refuel a hot or running engine. Do not smoke while ﬁ lling fuel tank or servicing fuel system.

• Keep your hands, feet, hair and clothing away from power-driven parts.

• Check for any loose electrical connections or faulty wiring.

• Engines should be operated only by

knowledgeable, qualiﬁ ed personnel.

• Look completely around engine to make sure that everything is clear before starting.

• Do not operate an engine that isn't in proper working order. If an unsafe operating condition is noted, tag the set and control panel so others will also know about the problem.

• Do not oil or grease engine while it is running.

• Provide ﬁ rst aid kits.

CAUTION: This symbol is used throughout this book to alert you to possible danger areas. Please take special notice of these sections.

Control Panels

Figure 4-A: Series 1-B Generator Control Panel

1. PREHEAT/ SHUTDOWN BYPASS

This switch serves two functions:

a. Preheats engine before beginning the starting

process. Press switch for 10-20 seconds before attempting startup.

b. Bypasses the safety shutdown feature during

the starting process. Keep switch engaged while starting engine, and for 2 to 3 seconds afterwards, allowing oil pressure to build beyond shutdown setpoint.

2. ENGINE CONTROL SWITCH

To start the engine, hold this switch in the START

position until the engine is running. After the engine starts, release the switch and it will return to RUN position. To stop the engine, hold the switch in the STOP position.

NOTE: The rocker switch is used on Series 1

panels only, and has a light that glows when the set is running.

3. HOUR METER

Keeps track of engine running time.

Figure 4-B: Series 3 Generator Control Panel

4. OIL PRESSURE GAUGE

Shows the oil pressure in the engine lubricating

system.

5. WATER TEMPERATURE GAUGE

Registers the temperature of the cooling water.

6. D.C. VOLTMETER

When the engine is stopped, the voltmeter indi-

cates the condition of the battery. When the engine is running, the voltmeter indicates the voltage output of the alternator.

For Series 4 Control Panels only:

7. A.C. VOLTMETER

Shows the generator output voltage.

8. FREQUENCY METER (Hertz)

The frequency meter indicates alternating current

frequency: 60 Hz (1800 RPM) or 50 Hz (1500 RPM).

9. AMMETER/VOLTMETER SELECTOR

Used to check the voltage and current of each

phase. Return to “Amps Off” position when not monitoring.

Operating Procedures

BREAK-IN PERIOD

1. The ﬁ rst 100 hours on a new or reconditioned engine are critical to its life and performance.

2. Constantly check the engine temperature and oil pressure gauges.

3. Oil consumption is greater during break-in as

piston rings take time to seat.

4. Break-In Oil Changes: Change engine oil and

ﬁ lter at 50 hours. Change oil and ﬁ lter again at 100 hours (consult Lubricants section for oil

recommendation).

Operating Instructions:

Maintain at least a 75% load on your generator set for the ﬁ rst 100 hours. If this is not possible,

maintain no less than a 50% load to ensure proper seating of the piston rings. Vary the load to help seat the rings.

BEFORE STARTING

1. Check the water level by removing the pressure cap from the expansion tank. In order

to give the cooling water an opportunity to expand, the level should be about 1 in. (2.5 cm) below the ﬁ ller cap sealing surface when the engine is cold.

CAUTION: Use protective clothing and open the ﬁ ller cap carefully when the engine is warm to prevent burns.

2. Check the oil level in the crankcase with the dipstick. The oil level must be between high and low marks on the stick. Never allow the level to go below this area. Always add the same viscosity of oil as is already in the

crankcase.

3. Check the fuel tank level and open any fuel valves on the tank and at the secondary fuel ﬁ lter.

4. Close the sea-cock, check and clean the sea strainer, and re-open the sea-cock.

5. Place the battery switch in the ON position.

NOTE: The battery switch must always be

kept ON while the engine is running. If the switch is turned OFF while the engine is running, the battery charging alternator could be damaged.

OM864W 09/07

Operating Procedures

STARTING

1. Hold the Shutdown Bypass switch in the ON position for 10-20 seconds before starting.

NOTE: Holding the switch too long can burn

out the glow plugs.

2. While holding the Shutdown Bypass switch in the ON position, push the Engine Control switch to the START position.

3. As soon as the engine starts, release both switches. Do not crank the starter for more than 20 seconds consecutively. If the engine fails to start with the ﬁ rst attempt, be sure that it has stopped completely before re-engaging the starter.

NOTE: Excessive cranking of the starter on

marine sets equipped with a water lift

mufﬂ er can cause engine damage. If the

engine does not start after 3 consecutive 20second cranks, remove the impeller from the seawater pump. This will prevent the

mufﬂ er from ﬁ lling with water and backﬁ lling the exhaust line and engine. Once

the engine starts, shut it off immediately and reinstall the impeller.

Restart and check the exhaust overboard outlet for gushes of water.

OPERATING

1. Units with Series 3 and Series 4 Control Panels:

Check gauges often. Oil pressure must be

above 15 PSI. The D.C. voltmeter should read between 11 and 15 volts at 80° F (25° C) ambient temperature. The water temperature gauge must be below 200° F (94° C). Check the A.C. voltage and frequency meters (Series 4 panel). If the gauges deviate from normal levels, shut down the generator set and investigate.

2. Let the unit run unloaded for a three to ﬁ ve minute warm-up period.

3. Add electrical load.

STOPPING

1. Remove electrical load from the generator set.

2. Run the engine for a three to ﬁ ve minute cool- down period.

3. Move the Engine Control switch to the STOP position until the engine stops completely.

4. Shut off seacock, fuel valve, and battery switch.

Operating Procedures

SHUTDOWNS AND ALARMS

1. Your unit is ﬁ tted with a system to protect it from high water temperature or low oil pressure.

a. Generator sets have shutdown systems to stop the engine. They have no warning horns. b. Other alarms and shutdowns are available as optional equipment.

NOTE: If your unit is equipped with optional shutdowns and alarms, do not rely on the warning or shutdown system to the exclusion of careful gauge monitoring. Watching your gauges can prevent damage to the unit and dangerous power losses.

2. Do the following when your warning or shutdown system is activated:

a. Check the temperature gauge. If above 205° F (96° C), shut off the engine immediately. b. Use the Trouble Shooting Guide on page 26 to isolate the cause of the overheat.

SPARE PARTS

1. ADE recommends that you keep the following spare parts on hand for ﬁ eld

service. The parts are available from your local Northern Lights dealer. Some marine models may already have “On-Board Kits,” a handy box that contains the most common parts you will need.

a. Primary and secondary fuel ﬁ lter elements b. Oil ﬁ lters c. Air ﬁ lter elements d. Alternator belt e. Thermostat and gaskets f. Seawater pump impeller and gaskets g. Glow plugs h. Injector and washer

2. If your set is operating a long distance from a servicing dealer, add the following:

CAUTION: Do not remove the water ﬁ ll cap of an overheated engine. Escaping high temperature steam can cause severe burns. Allow the engine to cool and then remove the cap slowly using protective clothing.

c. Make repairs and restart after the temperature gauge registers below 200° F (94° C). d. Watch the temperature gauge regularly and turn off the unit if the temperature rises above 205° F (96° C). Repeat troubleshooting.

3. If shutdown is activated and the temperature gauge shows temperature within normal temperature range:

a. Check the engine crankcase oil level. b. If the oil level is low, ﬁ ll with recommended lubricating oil and restart. Watch the oil pressure gauge carefully and shut off the engine if it does not show a normal reading (20-60 PSI) after a few seconds of operation. c. If the oil level is normal, DO NOT restart the engine. Call your dealer for assistance.

a. Complete set of injectors b. Copper washers for injector change c. Compelete set of glow plugs d. Fuel lift pump
