CAT (CATERPILLAR) excavator filter use and maintenance Caution:

(1) on the situation of wet air filter oil pan, engraved with "oil" and an arrow mark, the use of oil should be added to the required height. If the oil within the oil pan is too small, filtration ineffective, if the oil pan Too much oil will be sucked into the cylinder flex fuel, produce coke, serious, causing the engine to "speed."

(2) regular replacement of the engine oil pan, and clean the filter. When mixed with droplets of air constantly flowing through the gold dust filter, oil droplets on the screen gradually increased, and increasing, until large enough to adhere to the same filter along with the inflow of dust along the inner wall of the air cleaner housing outside the oil pan, oil pan outside dust gradually declined to the bottom of the upper part of clean oil added to the oil pan, then rose in the air to filter through continuous cycle , oil continues to act as washing the filter, but after long-time use cycle, foreign oil pan dust precipitation, more and more oil is dirty, clean the filter declining role, even clogged filter. Therefore, air filter should be replaced periodically oil situation is within the oil pan, and clean the filter.

(3) Always check the tightness of all connections to prevent unfiltered air from the cracks into the cylinder inspection method is as follows: when the engine is at low speed, the air filter will love the coarse filter (cyclone cover) Remove with palm block the intake pipe opening, if the intake system tight, and can be observed that the rapid decline in engine speed and stall until black smoke. If the speed did not decrease significantly, and inhale "hissing" sound, it means that the intake The system does not close, unfiltered air to go "short" into the cylinder.

Note: Do not wait until it will turn off the palm open, in order to avoid excessive carbon deposition cylinder.
