848118 Volvo.Penta Nut

Starting Between 60° F. and 32° F. Using Glow Plugs: After positioning the controls correctly, the diesel engine may be started as follows. See the topic, GLOW PLUGS.1. Turn the HEAT-START switch to the HEAT position; on earlier engines equipped with a HEAT switch and a START switch, move the HEAT switch to ON for the length of time necessary as indicated in the STARTING AID CHART. Each glow plug uses approximately 5 amperes while the switch is in the HEAT position. This is actually a small amount in comparison to the starter load that is imposed on the battery when the switch is in the START position.2. Turn the switch to the START position. As soon as the engine starts, turn the switch back to the HEAT position until the engine is running smoothly.If the engine fails to start after 10 seconds of cranking, turn and hold the switch in the HEAT position for about 30 seconds before cranking the engine again. When the starting motor is cranking, the battery voltage is reduced and the glow plugs cool. Reheating them after 10 seconds of cranking makes the glow plugs more effective and conserves the battery. Do not turn the switch to the HEAT position while the engine is warm and running.
HEAT-START SWITCH (Later Engines)
CONTROL SWITCHES (Earlier Engines)
1-HEAT switch. 2-START switch.After the engine starts, reduce the engine speed to low idle until the oil pressure gauge indicates normal oil pressure. When the gauge indicates normal oil pressure, the engine should be allowed to run for five minutes with the governor control lever at approximately half engine speed position before applying the load. During this period the engine gauges should be observed for proper readings as explained in the topic, GAUGES. Starting the Diesel Engine Below 32° F. Using Glow Plugs and Ether Starting Aid: After positioning the controls correctly, the diesel engine may be started as follows. See the topics, GLOW PLUGS and ETHER STARTING AID.1. Load the discharger by unscrewing the nut (2), removing the spent capsule and placing the new capsule (3) in the discharger as shown. Install the nut finger tight.2. Turn the HEAT-START switch to the HEAT position for the length of time necessary as indicated in the STARTING AID CHART. Each glow plug uses approximately 5 amperes while the switch is in the HEAT position. This is actually a small amount in comparison to the starter load that is imposed on the battery when the switch is turned to the START position.3. Discharge ether by moving the discharger lever (1) to pierce the capsule. See the STARTING AID CHART for the number of capsules required. Be sure the spent capsule is left in the discharger when the engine is running and the nut (2) is finger tight on the discharger to keep dirt out of the engine.Actual experience will determine the number of capsules required for easy starting.
ETHER DISCHARGER
1-Discharging lever. 2-Nut. 3-Capsule.If more than one capsule is needed in the manifold, discharge the first two capsules and install the second set of capsules in the dischargers before cranking the diesel engine. Only one or two capsules should be discharged into the manifold before cranking the engine. The discharge of the second set of capsules can be performed when the engine has been cranked a few revolutions, or when it starts to stall.4. Move the switch to the START position. As soon as the engine starts release the switch and discharge ether capsules as required to prevent stalling, until the engine is running smoothly. Do not move the switch to the HEAT position while the engine is warm and running. If the engine does not start after 10 seconds of cranking, turn the switch to the HEAT position for 30 seconds, then repeat the starting procedure.After the engine starts, reduce the engine speed to low idle until the oil pressure gauge indicates normal oil pressure. When the gauge indicates normal oil pressure, the engine should be allowed to run for five minutes with the governor control lever at approximately half engine speed position before applying the load. During this period the engine gauges should be observed for proper readings as explained in the topic, GAUGES.
Do not discharge more than 2 ether capsules without cranking the engine.
