Water temperature when starting Preheating time to 7 ° C (to 44.6 ° F) - The table on the right gives a guide to the preheating time (sec) in cold weather. The preheating time is set to approx. 12 seconds when the engine water temperature is 0 ° C (32 ° F).

7 ° C to -0 ° C (44.6 ° F to 32 ° F) 10 seconds to 17 seconds -0 ° C to -10 ° C (32 ° F to 14 ° F) 17 seconds to 26 seconds REMARK The preheating time is set to give priority to ease of starting, but if the black smoke is considered to be a problem, it is possible to start the engine before the preheating pilot lamp goes out by turning the key in starting switch (1) to the START position. -10 ° C to -20 ° C (14 ° F to -4 ° F) 26 seconds to 36 seconds -20 ° C to -30 ° C (-4 ° F to -22 ° F) 36 seconds to 45 seconds 2.
