When replacing or cleaning filter core, clean the inside of
air cleaner housing. See Fig. 2-12-3.
Caution:
(1) The paper filter core is not allowed to be washed with
oil or fresh water, or else the filter core will be
contaminated and blocked by dust very easily, and this
will cause insufficient air intake; as a result, power loss
and black smoke in exhaust may result.
(2) The tightness at the joint between the air intake tube
and air cleaner must be checked regularly. If leakage is
found, the packing and tightening connector should be
replaced to avoid abnormal wear of the diesel engine.
