Komatsu — Air Cleaner Clogging Monitor

Hydraulic Oil Temperature Monitor OPERATION If this monitor (2) lights up white in low temperatures, carry out the warming-up operation. For details, See “Warming up Hydraulic Equip- ment” on page 2-98. Fuel Level Monitor This monitor (3) lights up to warn the operator that the level in the fuel tank is low. If the remaining amount of fuel goes down to 41 l (10.83 US gal), the light changes from green to red, so add fuel as soon as possible. Charge Monitor This monitor (4) warns the operator that there is an abnormality in the charging system when the engine is running. If the battery is not being charged properly while the engine is running, it lights up red.

If it lights up red, check for looseness of the V-belt. If any abnormality is found, take the necessary action. For details, See “Electrical System Problems” on page 2-154. Remark While the ignition switch is ON, the lamp will remain lit and will go off once the engine is started. When the engine is started or stopped with the ignition switch at the ON position, the lamp may light up and the buzzer may sound momentarily, but this does not indicate any abnormality. Air Cleaner Clogging Monitor This monitor (5) warns the operator that the air cleaner is clogged. If it lights up red, stop the engine and inspect and clean the air cleaner. PC350LL-7E0 2-13
