Accumulation of flammable material (dead leaves, twigs, grass, etc.) around the battery may cause fire, so always check and remove such material. Keep the top surface of the battery clean and check the breather hole in the battery cap. If it is clogged with dirt or dust, wash the battery cap to clear the breather hole.
Check for damage and wrong capacity of the fuse and any sign of disconnection or short circuit in the electric wiring. Check also for loose terminals and tighten any loose parts. Check the wiring of the “battery”, “starting motor” and “alter- nator” carefully, in particular. When carrying out walk-around checks or checks before starting, always check if there is any accumulation of flammable material around the battery, and remove such flammable material. Please contact your Komatsu distributor for investigation and correction of the cause. CHECK FOR WATER AND SEDIMENT IN WATER SEPARATOR The water separator separates water mixed in the fuel.
If float 2 is at or above red line 1 , drain the water. For the draining procedure, see section “24.2 WHEN REQUIRED”. Even if a water separator is installed, be sure to check the fuel tank to remove water and sediment in the fuel. AE063830 2-59
