Inspection and Cleaning
Every day, check for oil, coolant, or fuel leaks. Also check for loose electrical connection. Check oil
pressure with engine running at rated RPM (2500). Do not operate engine if oil pressure is less than
20 psi (138 kPA). Wipe accumulated water off from all electrical connections and instruments. Make
sure that the battery voltmeter reads proper voltage.
Every week, wipe off accumulated dust, dirt and oil from the engine and generator. Check all parts for
loose connections and wear. If arcing has occurred at any electrical connections, recondition them and
securely refasten. Check engine oil and coolant levels.
Every month, check generator for amperage and voltage output. Blow out generator windings with
compressed air, not over 25 psi (172 kPa) pressure or remove with a suction-type cleaner with a
non-metallic nozzle. If windings should become slightly damp, use space heaters or electrical light
bulbs to effectively dry out the windings. If dampness is excessive, apply external heat under a canvas
cover, well vented. Heating should not exceed 194º F (90º C).
Pound out any dents in the canopy. Sand, prime, and repaint any dented or rusted spots.
