GENERAL INSPECTION

Prior to each use, the generator should be cleaned and inspected for defi ciencies. Check for loose, missing or damaged nuts, bolts or other fasteners. Also check for fuel, oil, and coolant leaks. Use Table 14 as a general maintenance guideline. Engine Side, refer to the Engine Instruction Manual.

AIR CLEANER

Every 250 hours: Remove air cleaner element (Figure 57) and clean the heavy duty paper element with light spray of compressed air. Replace the air cleaner as needed.

Air Cleaner with Dust Indicator

This indicator (Figure 57) is attached to the air cleaner. When the air cleaner element is clogged, air intake restriction becomes greater and the dust indicator signal shows RED meaning the element needs changing or service. After changing the air element, press the dust indicator button to reset the indicator.

NOTICE

The air fi lter should not be changed until the indicator reads “RED”. Dispose of old air fi lter. It may not be cleaned or reused.
