Maintenance • Use a vacuum to pick up loose dirt and debris. • Low pressure air (not to exceed 25 psi) may be used to blow away dirt. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed. NOTICE: DO NOT use a garden hose to clean generator. Water can enter engine fuel system and cause problems. If water enters generator through cooling air slots, some water will be retained in voids and crevices of rotor and stator winding insulation. Water and dirt buildup on generator internal windings will decrease insulation resistance of windings. Engine Maintenance WARNING Accidental start-up. Disconnect spark plug wires when working on unit. Fail- ure to do so could result in death or serious injury.
