fuelsupply device for starting(if have)，and starting the engine．The handle of the device should
bereset after engine's started·If the engine can
，
t be started，repeat the above operating after
about l minute．Oil pressure gauge should immediately indicate number values after engine
started．The extra fuel supply device for auxiliary starting device should not to be used during
starting in thermal state．
低温起动
Low temperature starting
装有电子控制火焰预热起动装置。
With electronic control flame preheating device
发动机水温低于 -23℃时，打开钥匙开关，预热指示灯亮，电热塞通电加热，经 50S
后预热指示灯自动闪烁。电热塞已加热到 850-950℃，按下起动按钮，接通起动机，电磁
阀自动打开油路，给电热塞供油，进行火焰预热起动，可使发动机在 -25℃下顺利起动。
When the temperature of coolant inside the engine is lower than-23 ℃，turn on the
electronickey，the preheating indicator lighting，the heating plug is heated，and the preheating
indicatorwill be automatically flickered after 50S．When the heating plug is heated to
