4. Air Cleaner Service
Refer to Section 1-1; Fig. 4. This air cleaner is a dry type which may be cleaned as many as six times be-
fore replacing it with a new air cleaner. A definite time schedule for cleaning or changing the air cleaner
cannot be determined because of varying operating conditions. However, since this air cleaner can be re-
moved and replaced without difficulty on this generator set
(simply by loosening one metal clamp on each
end of the air cleaner)
, it may be inspected either at prescribed service intervals or at any time deemed
necessary.
A. Inspecting the Air Cleaner
(1) Make periodic checks of air cleaner inlet screen for obstructions. If any obstructions are present,
remove them.
(2) Check outlet connection for proper seal.
NOTE : DO NOT judge the element’s life just by looking at it, IT SHOULD LOOK DIRTY, or it’s not
doing its job.
