Maintenance Cooling System Cooling System Clean the radiator fins every 8 hours of operation. Spray the radiator with water from a hose or compressed air to clean sawdust from the radiator fins. Do not use a pressure sprayer. CAUTION! Failure to keep the radiator fins clear of sawdust and/or dirt may cause the engine to overheat resulting in damage to the engine.
Maintenance Fuel Filter Fuel Filter See Figure 2-1. Replace the primary fuel filter cartridge every 1500 hours or one year of operation. After replacing the filter cartridge, loosen the air bleed screw and operate the 1500 fuel pump bail until fuel begins to flow from the valve and is free of air bubbles. Tighten the bleed screw.
Maintenance Battery Battery Check the battery electrolyte level every 50 hours of operation. See manufacturer’s man- ual for instructions. DANGER! Batteries expel explosive gases. Keep sparks, flames, burning cigarettes, or other ignition sources away at all times. Always wear safety goggles and a face shield when working near batteries.
