WP13 Diesel Engine Series Operating Manual

The diesel engine allows the maximum intake resistance of 7kPa, which shall be checked when the
diesel engine is working at the rated speed and full load, and when the intake resistance reaches the
maximum allowable limit, the filter element should be cleaned or replaced according to the
provisions of the manufacturer.
Note: never use the engine in the absence of air filter. Otherwise, dirt and impurities will enter
the diesel engine to result in premature wear.
Remove the air filter element from the air filter and pat the end face to remove the dust, or you can
use compressed air to purge it (from the inside outward).
