3. BEFORE OPERATION 3.1 Fuel Oil, Lube Oil & Cooling Water 3.1.1 Fuel [NOTICE] Use of fuels not recommended in this Operation Manual may cause a decrease in engine performance and cause components to fail. (1) Selection of fuel Use the following diesel fuels for best engine performance: ISO8217 DMA, BS2869 A1 or A2 Fuels equivalent to Japanese Industrial Standard, JIS. No. K2204-2 Cetane fuel number should be 45 or greater (2) Fuel Handling 1) Water and dust in the fuel oil can cause operation failure.
3.1.2 Lube oil [NOTICE] (1) Selection of Engine Lube Oil Using other than the specified lube oil will lead to seizure of parts inside the engine and gear device, abnormal wear, and shorten engine life. It will also effect the starting ability and power output. Use the following lube oil: *API Classification..............CD (Standards of America Petroleum Institute) *SAE Viscosity.....................
(1) Handling of Cooling Water 1) Always use purified soft water or distilled water for the fresh water. Never use dirty water or hard water. Impurities in the fresh water cause scale and rust to build up on the cooling water passage, reducing cooling efficiency and causing the engine to overheat. 2) Choose LLC which will not have any adverse effects on the materials (cast iron, aluminum, copper, etc.) of the engine's fresh water cooling system.
3.2 Supplying Fuel DANGER Fires from Oil Ignition ● Be sure to use the correct type of fuel when refueling. Mistakenly filling with gasoline or the like will result in ignition. ● Be sure to stop the engine before refueling. If you spill fuel, wipe such spillage carefully. ● Never place oils or other flammable material close to the engine as this could result in ignition. 3.2.1 Filling the Fuel Tank Fill the tank with clean fuel which has not been contaminated with water or dust.
● 4LHA-HTP/-HTZP ① Open the cock on the fuel oil inlet pipe line. ②Loosen the air bleeding screw on the fuel filter by turning 2~3 times to the counter-clockwise using a screw driver. Air bleeding screw ③Feed the fuel with the priming pump. The priming pump is on the top of the fuel filter. Move the priming pump knob up and down until fuel mixed with air bubbles flows out of the air bleeding port. ④When the fuel coming out is clear and not mixed with any bubbles, tighten the air bleeding screw. 3.
3.4 Supplying Marine Drive Oil ● Marine gear (HSW450A2, HSW630A1) For the marine gear, follow the maker's instructions. [NOTICE] Do not overfill. Overfilling will cause oil to be sprayed out during operation and effect the efficiency of the marine drive. ● For MERCRUISER's stern-driven device (BRAVO), supply lube oil in accordance with the maker's instructions. (4LHA-HTZP/-DTZP/-STZP) ● For MERCRUISER's stern-driven device (BRAVO), there is the power steering oil service tank on the engine side.
3.5 Supplying Cooling Water DANGER Burns from Scalding ● Never remove the filler cap of the fresh water cooler while the engine is still hot. Steam and hot water will spurt out and seriously burn you. Wait until the water temperature has dropped, then wrap a cloth around the cap and loosen it slowly. ● After inspection, refasten the cap firmly. If the cap is not secure, steam or scalding water may be emitted during operation causing burns.
⑥Check the rubber hose connecting the subtank to with the fresh water tank. If the hose is not water-tight a lot of coolling water will be consumed. filler cap 3.6 Cranking When the engine is being used for the first time or if it has not been used for a long period of time, perform cranking before starting to distribute oil to all of the parts.
3.7 Checking the Lube Oil and Cooling Water When lube oil, gear oil, and cooling water are put in for the first time, or after they have been replaced, their levels should be checked after a trial operation. Oil and water will be distributed to the various parts during the operation, lowering the levels of oil and water. Replenish to the proper amounts. ● Supplying engine lube oil ● Supplying marine drive oil ● Supplying cooling water → See 3.3 → See 3.4 → See 3.
4. HOW TO OPERATE WARNING Alcohol ● Never operate the engine while you are under the influence of alcohol or when you are ill or feel unwell as this results in accidents. WARNING Exhaust Gas Poisoning ● Be sure to establish good ventilation in the engine room with windows, vents, or other ventilation equipment. Check again during operation to be sure that ventilation is good. Exhaust gas contains poisonous carbon monoxide and should not be inhaled.
(4) Checking and Resupplying Marine drive Oil ①Refer to the instructions accompanying the marine drive for the amount of lube oil. ②Supply with the recommended oil if necessary. (5) Checking and Resupplying Cooling Water DANGER Burns from Scalding ●Never remove the filler cap of the fresh water cooler while the engine is still hot. Steam and hot water will spurt out and seriously burn you. Wait until the water temperature has dropped, then wrap a cloth around the cap and loosen it slowly.
4.2 Checking the Control Panel and Alarm Devices Be sure to check the alarm devices and other instruments on the panel before and after starting the engine. If the devices are not working properly, it is impossible to prevent any problems arising from insufficient oil and water in the engine. Make checking the alarm and other devices before and after starting a regular practice. If having the optional control panel New B or New C or New D-typ, refer to 2.5.1(2) 4.3 Starting 4.3.
4.3.3 Restarting After Starting Failure When attempting to restart the engine after starting failure, be sure that the engine is at a complete stop before turning the starter switch key. If the engine is restarted while the engine still has not stopped, the pinion gear of the starter motor will be damaged. ● When the engine will not start after several [NOTICE] attempts, check the fuel system.
4.4 Adjusting the Engine Speed Adjust the speed of the engine by moving the remote control handle slowly and smoothly. Move the handle forward and adjust the speed between low speed and high speed. ■For the Morse remote control handle, adjust the speed between ▲FWD and ▼REV. [NOTICE] For a new engine be especially careful not to change speeds abruptly or attach a heavy load for the first 50 hours of operation. Doing so will result in damage and shorten the life of the engine. 4.
4.6 Check During Operation Always be on the look out for problems during engine operation. Pay particular attention to the following. (1) Is sufficient water being discharged from the seawater outlet pipe ? If the discharge is small, stop the engine immediately, identify the cause and repair. (2) Is the exhaust color normal ? The continuous black exhaust smoke shows engine overloading. This shortens the engine's life, so should be avoided.
4.7 Stopping the Engine [NOTICE] Stop the engine in accordance with the following procedures. Stopping the engine suddenly after operating at high speed without cooling it down will cause the engine temperature to rise quickly resulting in deterioration of the lube oil and sticking of parts. ①Stop the boat. Put the remote control handle in NEUTRAL to stop the boat. ②Be sure to race the engine before stopping it. →See 4.6 (7) ③Cool down the engine at low speed (1000rpm or lower) for about 5 minutes.
4.8 Operation Procedure The following diagram shows the procedures for operation explained up to this point. Parts of the operation may differ depending on the marine drive and remote control system being used. Accompanying operation manuals should be read carefully and understood.
4.9 Long-Term Storage 4.9.1 Before storing for long periods of time, perform the following. (1) Periodic Inspection If the time for a periodic inspection is close, perform it before storing the engine for a long period of time (3 months or more) (2) Draining the Cooling Water When not using LLC, be sure to drain the water from the inside of the engine.
■Draining the water from the cooling fresh water system If antifreeze has not been added to the fresh cooling water, be sure to drain the water from the fresh water system. ①Open the drain cock at the side of the cylinder block, and drain off the water inside. ②Open the fresh water cooler cock and drain off the water inside. ③Open the drain cock on the fresh water pipe of the front of engine (under the cooling fresh water pump) ④Close the drain cocks after draining the water.
5. MAINTENANCE & INSPECTION Conduct Periodic Inspection for Your Safety. The functions of engine components will degenerate and engine performance will fall according to the use of the engine. If periodic inspections are not performed, you may encounter unexpected troubles while cruising at sea, and consumption of fuel or lube oil may become excessive and exhaust gas and engine noise may increase. These all shorten the life of the engine.
5.1 List of Periodic Inspections Daily and periodic inspection are important to keep the engine in its best condition. The following is a summary of inspection and servicing items by inspection interval. Periodic inspection intervals vary depending on the uses, loads, fuels and lube oils used and handling conditions, and are hard to establish definitively. The following should be treated only as a general standard.
5.2 Periodic Inspection Items 5.2.1 Inspection After Initial 50Hrs. Operation (1) Replacing the Engine Lube Oil and Lube Oil Filters (1st time) CAUTION Precautions for Removing Hot Oil to Prevent Burns If extracting oil from the engine while it is still hot, do not let the oil splash on you. During initial operation of the engine, the oil is quickly contaminated due to the initial wear of internal parts. The lube oil must therefore be replaced early. Replace the lube oil filter at the same time.
5.2.2 Inspection Every 50 Hours (1) Draining the Fuel Tank (local supply) ①Put a pan under the drain to catch the fuel. ②Loosen the drain cock at the bottom of the fuel tank, and drain off any water and dirt collected inside. ③Once the water and dirt have been drained off and the fuel coming out is clear, close the drain cock. (2) Draining the Oil/Water Separator (Optional) Air bleeding plug ①Close the fuel cock.
(3) Drain the fuel filter When water and dirt are mixed in with the fuel, it becomes impossible for the fuel injection pump and the valve to work. Drain periodically to keep the filter from becoming clogged. When there is a lot of drain collected in the oil/water separator at the bottom of the fuel filter, the fuel filter alarm lamp on the control panel (optional) will light up. (4LHA-HTP/-HTZP) 1) 4LHA-HTP/-HTZP ①Close the fuel cock on the fuel pipe line.
(4) Inspection of Battery WARNING Fire due to Electric Short-Circuits Always turn off the battery switch or detach the earth cable (-) before inspecting the electrical system. Failure to do so could cause shortcircuiting and fires. Proper Ventilation of the Battery Area Be sure the area around the battery is well-ventilated and there is nothing which could start a fire. During operation and charging, hydrogen gas is emitted from the battery and can be easily ignited.
5.2.3 Inspection Every 250 Hrs. or 1 yr. (1) Replacing the Fuel Filter 1) 4LHA-HTP/-HTZP ①Close the fuel cock of the fuel tank. ②Drain the fuel from the fuel drain cock at the bottom of fuel filter. See. 5.2.2(3) Fuel filter Loose tighten ③Remove the connectors of the wiring and remove the alarm switch using spanner. ④Remove the fuel filter using filter wrench. ⑤Tighten the new fuel filter. (Clean the fuel filter mounting surface). Alarm switch Part No.
(2) Replacing Engine Lube Oil and Lube Oil filter. (See 5.2.1(1)) (3) Replacing Cooling Fresh Water Cooling performance drops when the cooling water is contaminated with rust and scale. Even if LLC is added, the cooling water must be periodically replaced because the properties of the agent will degenerate. Replace the cooling water periodically. ● ● Draining the Cooling Fresh Water Supplying Cooling Fresh Water → See 4.9.1. → See 3.5.
(5) Adjusting the Remote Contorol Cable 1) Adjusting the engine speed control cable Check the governor lever (speed control lever) at the engine side makes unifom contact with the high speed and low speed side stopper when the remote control handle is in the high speed (high idle) or low speed (idle) position. If either the high speed or the low speed side does not make contact with stopper.
(6) Washing the Turbocharger Blower [NOTICE] When engine speed seems sluggish or the exhaust color poor, the blades of the turbocharger blower may be dirty. Wash the blower in the following manner. ①Have ready blower wash (liquid detergent), fresh water, and a small pitcher. Blower Wash (4L) Parts Code : 974500-00400 Do not pour in a large amount of blower wash at one time (pour it in gradually) as this can damage the blower blades and get water hammer in the combustion chamber leading to accidents.
5.2.4 Inspection Every 500 Hrs.or 2 yrs. (1) Checking the Tension of the V-Belt of the Alternator When there is not enough tension in the V-belt, the belt will slip making it impossible for the alternator to generate power. Additionally, the fresh water pump will not work causing the engine to overheat. Check the tension of the V-belt in the following manner. ①Press the V-belt down with your thumb at the middle of the belt to check the tension.
(3) Inspecting Inner Parts of the Seawater Pump The discharge performance of the seawater pump falls depending on the use. The seawater pump must be inspected periodically. If the discharge volume of cooling seawater has decreased: (When disassembly servicing of the seawater pump is necessary, consult Yanmar dealer or distributor.) Direction of impeller blades Sea water pump ①Loosen the side cover set bolts and remove the side cover.
(2) Lapping of Intake/Exhaust Valves Adjustment necessary to maintain proper contact of valves and seats. This maintenance requires specialized knowledge. Consult your Yanmar dealer or distributor. (3) Inspection and Adjustment of Fuel Injection Timing Fuel injection timing must be adjusted to ensure optimal engine performance. This maintenance requires specialized knowledge. Consult your Yanmar dealer or distributor.
