12. OPERATION REMARK The time which should elapse before turning the preheating switch off varies with the ambient temperature. Confirm the time to the table below. Ambient temperature Time from the starting of engine until turning off the preheater switch 15 – 0°C 1 – 2 minutes Below 0°C 3 – 5 minutes REMARK When the air temperature is below 15°C, leave the valve open. If Step 6 to 8 are carried out without performing Step 1, it may shorten the nozzle life. Be sure to carry out Step 1. If the engine does not start through the steps specified above, return the fuel control lever to the engine stop position and repeat Steps 2 to 8 at an interval of approx. 2 minutes.
If the switch is moved to START while the preheating pilot lamp is on in Step 8, glow plugs will get wet, making firing impossible. This will make it difficult to start the engine. 2-51
