service time intervals by one-half of those specifi ed above.
2. When operating in the presence of dust or sand, reduce service time intervals by one-
half of those specifi ed.
3. When operating in excess of twelve hours per day, reduce service time intervals by
one-half of those specifi ed.
4. When operating in air with high moisture or salt, the servicing intervals need not usually
be changed. However, the unit should be inspected weekly to determine if additional
servicing be required. Also, have hydraulic fl uid tested quarterly.
5. For extended inactive periods, the engine should be started at least once a week
and run until thoroughly warm. Servicing time intervals may be extended from those
