Introduction This instruction book has been prepared to give you the greatest possible benefit from your Volvo Penta indus- trial engine. It contains the information you need to be able to operate and maintain the engine safely and cor- rectly. Please read the instruction book carefully and learn to handle the engine, controls and other equipment in a safe manner before you start the engine.
Read it carefully, as soon as possible after delivery. It includes important information about war- ranty cards, service intervals, maintenance, which it is the responsibility of the owner to know, check and carry out. If this is not done, AB Volvo Penta may fully or partly refuse to honor its warranty un- dertakings.
Presentation TD420VE, TAD420VE, TD520GE, TAD520GE and TAD520VE are in-line, direct injected, 4-cylinder industrial diesel engines. TAD620VE, TD720GE, TAD720GE, TAD720VE, TAD721GE, TAD721VE, TAD722GE and TAD722VE are in-line, direct injected, 6-cylinder industrial diesel engines. All engines are equipped with electronically controlled fuel management (EDC4), turbocharger, thermostatically controlled cooling systems and electronic speed control.
Presentation Identification numbers Location of engine signs The engines are supplied with two engine signs, of which one is installed on the right side of the engine block. Engine plate 1. Engine model 9. Air temperature in °C (°F), in accordance with 2.
Fault codes can also be output via the – speed sensor, camshaft CAN interface or with Volvo’s VODIA tool (including the Penta EDC4 software) at an authorized Volvo – coolant temperature sensor Penta workshop.
Instruments The engines are not supplied with instruments and controls. The choice of instrument type and controls is made by the customer. The functions available are described below. A. Engine speed potentiometer (throttle control) B. CAN interface SAE J 1939 C.
Starting the engine Make it a habit to check the engine and engine room before starting. This will help you to discover quickly if anything abnormal has happened, or is about to happen. Also check that instruments show normal values after starting.
Pre-heat the coolant with a separately installed elec- tric engine heater. In extreme cases, a diesel-burning engine heater may be needed. Ask your Volvo Penta dealer for advice. IMPORTANT! Make sure that the cooling sys- tem is filled with a glycol mixture. Please refer to the “Maintenance, cooling system”...
Starting the engine Never use start spray WARNING! Never use start spray or similar products as a starting aid. Explosions could oc- cur in the inlet manifold. The consequence could be personal injury. Starting with auxiliary batteries WARNING! Batteries (especially auxiliary bat- teries) contain hydrogen which is highly explo- sive in contact with air.
Operation Correct operation technique is very important for both fuel economy and engine life. Always let the engine warm up to normal operating temperature before operating at full power. Avoid sudden throttle openings and operation at high engine speeds. Checking instruments Engine speed control Check all instruments directly after starting, and then Avoid sudden and violent throttle opening.
Stopping the engine During longer breaks in operation, the engine must be warmed up at least once every fortnight. This prevents corrosion damage in the engine. If you expect the engine to be unused for two months or more, it must be laid up: Please refer to the “Laying up”...
IMPORTANT! When both operation and calendar time are specified, do the mainte- nance job at the interval which is reached first. Maintenance points marked must be done by an authorized Volvo Penta workshop. Daily, before first start • Engine oil, level check ................

Maintenance schedule Every 50-600 hours or at least every 12 months • Engine oil and oil filter, change ............. page 22-23 Oil change intervals vary, depending on oil grade and sulfur content of the fuel. page 26. Every 500 hours •...
8 hours. When operated in extremely dirty conditions, such as coal mines, stone crushing mills etc., special filters are needed (not sold by Volvo Penta). Air hoses. Leakage check. Inspect the condition of the hoses, for cracks and other damage.

It should be possible to press the belts down about 10 mm (3/16 “) between the pulleys. Worn belts which operate in pairs should be changed together. On TD420VE, TAD420VE and TAD620VE, the fan belts have an automatic belt tensioner and do not need to be adjusted.
If the 6 and 7 liter engines are equipped with a low-profile oil pan, the oil change intervals should be changed. VDS = Volvo Drain Specification Global DHD = Global Diesel Heavy Duty ACEA = Association des Constructeurs Européenne d’Automobiles...

Maintenance Viscosity Select the viscosity from the table below, for the ap- propriate continuous ambient air temperature. * Refers to synthetic or semi-synthetic oils. Oil change volume Please refer to the “Technical Data” chapter. Oil level. Inspection Make sure that the oil level is between the MAX and MIN marks.
The coolant should contain ethylene glycol of a good quality with a suitable chemical consistency for an ade- quate protection of the engine. Using anti-corrosion aditive exclusively is not permitted in Volvo Penta’s engines. Never use water by itself as coolant.
Page 27
(18°F). (Using 60 % glycol lowers the freezing point to -54 °C (65°F)). Never mix more than 60 % concen- trate (Volvo Penta Coolant) in the cooling liquid, this will give reduced cooling effect and increase the risk of overheating, and will give reduced freezing protec- tion.
Page 28
Maintenance Coolant. Checking and filling WARNING! Do not open the filler cap when the engine is warm, except in emergencies. Steam or hot fluid could spray out. Check the coolant level daily before starting. Top the coolant up as necessary. The level should be about 50 mm (2”) below the sealing plane of the filler cap, or between the MIN and MAX markings, if a separate expansion tank is installed.
Page 29
Maintenance Coolant. Draining. The engine must be stopped before draining, and the filler cap unscrewed. WARNING! Do not open the filler cap when the engine is warm, except in emergencies. Steam or hot fluid could spray out. Open the drain taps and remove the drain plugs (po- sitions are shown below).
Page 30
Maintenance Cooling system Flushing Cooling performance is reduced by deposits in the radiator and cooling galleries. The cooling system should be flushed when the coolant is changed. 1. Drain the coolant, as in the description on the pre- vious paragraph. 2.
Maintenance Fuel system Only use the grades of fuel recommended in the fuel specification below. Always observe the greatest cleanli- ness during re-fueling and work on the fuel system. All work on the injection system of the engine must be done by an authorized workshop. If the seal on the in- jection pump is broken by an unauthorized person, all warranties are void.
Page 32
Maintenance Fuel system. Venting The fuel system must be vented after a filter change, if the fuel tank has been run dry, after a long-term stoppage etc. Use the hand pump, if fitted, to vent the fuel system. In other cases, vent the system by operating the starter motor.
IMPORTANT! Never disconnect the current with the main switch when the engine is running. Electrical connections Check that electrical connections are dry, free from oxide and that they are securely tightened. Spray these connections as necessary with water-repellent spray (Volvo Penta universal oil).
