DIESEL ENGINE MAINTENANCE INSTRUCTION FOR GENERATOR

HOW TO MAINTAIN THE LUBRICATION SYSTEM OF VOLVO PENTA ENGINE

1) Oil level, checking and topping up- Engine oil, change.

- Dipstick is marked signs "Stop" and "Operating", so we can check the oil level both operating and stopping engine.

- The oil level is compulsory inside marked area in dipstick. Don't top up oil more than marked area.

- Just top up oil when the engine stops.

- Just use oil in "Oil Recommendation" on page 90 in Volvo's operator's manual.

- Change engine oil after 600 operating hours or twelve months.

- Connect the drain hose to the oil drain pump and pump old oil outside and then remove the drain hose and fill up with engine oil.

2) Oil Filter-Pass Filter, Change.

1- Clean the oil filter bracket (2).

2- Remove all oil filters with a suitable oil filter extractor (1).

3- Clean the mating surface of the oil filter bracket. Make sure that no pieces of old oil seal are left behind. Carefully clean round the inside of the protective rim (2) on the oil filter bracket.

4- Put a thin layer of engine oil on the seal rings of the new fuel filters.

5- Install the new oil filters. Tighten the filters ¾–1 turn after they touch.

6- Top up with engine oil, start the engine and let it run for 20-30 seconds.

7- Turn off the engine, check the oil level and top up as required.

8- Check sealing round the oil filters.

HOW TO MAINTAIN THE FUEL SYSTEM OF VOLVO ENGINE

1) Draining condensate, fuel system.

1- Open the drain nipple (1) in the base of the fuel prefilter.

2- Tighten the drain tap (1) when fuel without water starts to run out.

2) Engine Fuel Filter Replacement.

1- Clean round the fuel filter.

2- Remove the filter with a suitable filter remover. Collect any spilled fuel in a collection vessel.

3- Clean the filter mating surface on the filter bracket.

4- Lubricate the seal with diesel fuel and install the new fuel filter. Tighten the fuel filter in accordance with the instructions on the fuel filter.

5- If necessary, vent the fuel system, please refer to

3) Fuel Pre-filter, change.

1- Undo the cable from the water trap sensor.

2- Remove the water trap filter from the filter housing. Collect any spilled fuel in a container.

3- Remove the lower part of the water trap from the filter.

4- Clean the lower part of the water trap with a soft rag. Check that the drain hole in the lower part is not blocked.

5- Install a new seal on the lower part and lubricate the seal with diesel fuel. Re-install the lower part of the filter.

6- Lubricate the seal with diesel fuel. Screw the filter onto the filter bracket by hand until the rubber seal just touches the mating surface. Then tighten a mfurther half turn, no more.

7- Connect the cable to the water trap sensor.

8- If necessary, vent the fuel system, please refer to Bleeding the Fuel System.

4) Fuel System, bleeding

1- Check that there is sufficient fuel in the tank, and that any fuel taps are open.

2- Release the hand pump on the fuel bracket by pushing down and twisting the plastic handle.

3- Vent the fuel system by pumping with the hand pump. Air is vented to the tank via the fuel return pipe. No venting nipples need be opened.

4- Start the engine and allow it to idle fast for about 10 minutes.

5- Perform a leakage and function check.

HOW TO MAINTAIN THE COOLING SYSTEM OF VOLVO GENERATOR ENGINE

- Different types of coolant must not be mixed with each other.

- Risk of reduced cooling function and performance by clogging and isolation..

- Follow the mixing recommendation on the product.

- The coolant should be mixed with distilled, deionized water. For Volvo Penta specified water requirements

# NOTICE:

Always use “Ready Mixed” coolant if water quality cannot be determined or if it does not fulfill ASTM D4985.

Never mix more than 60% concentrated coolant with water.

1) Coolant Level, Checking and Topping up.

# NOTICE:

- Do not open the coolant filler cap when the engine is hot, except in emergencies as this could cause serious personal injury. Steam or hot fluid could spray out

- Only use coolant recommended by Volvo Penta. Fill up with the same type of coolant that is in the system. Different types of coolant must not be mixed with each other

- Filling of coolant must be performed with the engine stopped. Fill up slowly, to allow the air to flow out. Check the coolant level daily before start.

# Carry out:

- TWD16:

1- Open the filler caps (1).

2- Check that the coolant reaches the MAX mark on the sight glass (2). Top up with coolant as required

3- Close the filler caps.

- TAD16:

1- Open only the filler cap (1). Do not open the pressure cap (2).

2- Check that the coolant level is between the MIN and MAX marks on the expansion tank (1). Top up with coolant as required

3- Close the filler cap.

2) Filling a completely empty system.

- Mix the correct amount of coolant in advance, to ensure that the cooling system is completely filled. Refer to Technical Data, page 91 for the correct coolant volume.

- Do not start the engine until the cooling system is completely filled and vented.

- If a heating unit is connected to the engine cooling system, the heating control valve should be opened and the installation vented during filling.

- Carry out topping up in the cooling system:

2- TWD16:

Open the caps to both the expansion tank (1) and the radiator (2). Fill the expansion tank so that the coolant reaches the MAX mark on the sight glass. Close the filler caps.

TAD16

Open only the filler cap (1). Fill the expansion tank so that the coolant level is between the MIN and MAX marks. Close the filler cap.
