16618 Mercury OIL STRAINER

Electric Starting
1. Move the governor control lever to approximate half engine speed position. 2. Use starting aids if required. See the topic, STARTING AIDS.3. Push the START button; or turn the HEATSTART switch to the START position, depending upon the control the engine has. Release the control as soon as the engine starts. For generator sets, place the AUTO-MAN switch in the MAN position to crank the engine. As soon as the engine starts, and the engine speed reaches 600 rpm and oil pressure is approximately 22 psi (1.5 kg/cm2), the starter motor will disconnect from the circuit. (The STOP position is used to stop the diesel engine.) If the engine fails to start in 10 seconds, move the governor control lever to the fuel off position, then continue to crank for 10 seconds. This will clear the cylinders of unburned fuel.If the engine fails to start after 30 seconds of cranking, allow the engine to cool for 2 minutes before repeating the starting procedure.
Prolonged cranking at low oil pressure can activate the mechanical safety shut-off. If the reset lever is in the shut-off position, reset the mechanical shut-off control.
NEVER use starting aids when the engine is warm and running.
If the engine is equipped with a Woodward PSG Governor, see the topic, WOODWARD GOVERNORS for the governor operation instructions.Air Starting
1. Open and close the bleed valve on the bottom of the air tank to drain condensation and oil carryover.2. Check the air supply pressure. The air start must have 100 PSI (7 kg/cm2) to operate properly.3. Keep oil level, in the oiler jar, at least half full. Add oil if necessary. See the LUBRICATION AND MAINTENANCE PROCEDURES, Filling Motor Oiler. 4. Push the air valve control in to crank the engine. As soon as the engine starts, release the valve. Starting Aids
Many variables can affect cold weather starting. Use the chart as a guide, but actual experience will determine when aids are necessary and how they should be used. Your engine may have one or more of the following starting aids:Glow Plugs (Precombustion Chamber Engines Only)
1. Push in and turn the HEAT-START switch to the HEAT position and hold for the approximate heating time shown in the STARTING AID CHART. 2. Turn the HEAT-START switch to the START position. 3. If necessary, when the engine starts turn the HEAT-START switch to the HEAT position. Hold the switch in this position until the engine is running smoothly.4. Release the switch.
NEVER use glow plugs when the engine is warm and running.
Starting Fluid
Starting fluid is volatile and must be stored away from heat and direct sunlight. If an aerosol container is used, follow the instructions on the container.
Spray starting fluid only while cranking the engine.
1. Heat the glow plugs (If equipped) for the approximate heating time shown in the STARTING AID CHART. 2. Turn the HEAT-START switch to START position. While cranking, spray starting fluid into the air inlet or air cleaner for approximately 1 second.
Wait at least 2 seconds before spraying starting fluid again.
3. If necessary, repeat the procedure.4. After the engine starts, it may be necessary to return the HEAT-START switch to the HEAT position until the engine runs smoothly.Jacket Water Heater (Attachment)
In very low temperatures, the lubricating oil must be warmed to allow starting. A jacket water heater can maintain the water temperature at approximately 90°F (32°C). The warm water will keep the oil in the upper part of the engine block warm enough to flow when starting.Dipstick Oil Heater
Contact your Caterpillar dealer before installing a dipstick crankcase oil heater.
Generator
Starting Single Unit Operation
1. Make all preliminary engine starting checks.2. Be sure the main or line circuit breaker is open.3. Start the engine and allow it to warm up.4. Close the main circuit breaker.5. Apply the load. Do not try to apply full load in one move, rather apply the load in increments to maintain system frequency at a constant level.Standby Generator Sets
Most standby units are automatic. They start, pickup the load, run and stop without an operator in attendance. Standby units can not change the governor control setting automatically. The throttle must be preset for the proper operation of that unit. Whenever the set is exercised or operated manually, be sure the throttle setting is correct for automatic operation. Check all switches to see they are properly set: Start Selector Switch in AUTOMATIC position and any Emergency Stop Switches in RUN position.Paralleling
Units may be paralleled at no load or paralleled with units under load. To parallel two or more units the following conditions must be met:1. Same phase rotation.2. Same voltage level.3. Same volt
