OPERATION Starting Switch Use the starting switch (1) to start or stop the engine. (A): OFF position It is possible to insert and remove the starting switch key at this position. When the key is turned to this position, all electrical system circuits are turned off and the engine stops. In addition, the parking brake is automatically applied. (B): ON position In this position, electric current flows to the charging circuit and lamp circuits. Keep the starting switch key at the ON position while the engine is running. If the ambient temperature is low when the engine is started, the preheating pilot lamp illuminates automatically and preheating starts.
The preheating time differs dependent on the ambient temperature when the engine is started. If the preheating pilot lamp illuminates, wait for it to go out and then turn the key to the START position. (C): START position This is the position to start the engine. Hold the key at this position while cranking the engine. Release the key immediately after the engine has started. The key returns to the ON position (B). Power Mode Selector Switch Use the engine power mode selector switch (2) to switch the engine output to match the purpose of the operation. When the P mode is selected, the power mode pilot lamp (P mode) on the machine monitor illuminates.
In addition, the economy mode pilot lamp (ECO) goes out. Position (a): E (economy) mode (low engine output): Operations with emphasis on fuel economy, such as operations on level ground where a maximum output is not needed. Position (b): P (power mode) (high engine output): Operations with emphasis on production Remark To carry out operations with effective fuel consumption, normally set the power mode selector switch to the E mode. The maximum engine speed is set lower than in the P mode but, except for hard operations such as heavy-duty digging of rock, it provides ample power and good fuel consumption.
By pressing the accelerator pedal lightly, it is possible to reduce the fuel consumption. Set to the P mode when carrying out heavy-duty digging operations of rock or operations where speed is required, or when traveling at high speed on flat ground. 2-44 WA430-6
