TROUBLE SHOOTING INFORMATION
10.0
As an aid in locating and correcting problems which may occur in transit or while the cleaner is in
operation, this section was developed to assist the operator, Many operational problems are caused by
inexperienced operators rather then mechanical failures, With this in mind, this list was prepared as
completely as possible to remedy problems and eliminate unnecessary maintenance in the furure.
