This manual only provides information about additional procedures or procedures to be performed at dif- ferent time intervals than found in the manufacturer's manu- als.
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.
Maintenance Alternator Belt Alternator Belt The belt tension should be checked after the first 100 hours of operation, when the bat- tery is not charging properly or when the alternator belt is squealing. If the battery contin- ues to not charge properly or the belt continues to squeal after the initial belt adjustment, replace the belt.
Maintenance Radiator Fan Belt Adjustment 6. After the alternator belt has been tensioned, tighten the adjustment bolt jam nut. Tighten the upper and lower pivots and replace the belt covers. Radiator Fan Belt Adjustment The fan belt tension should be checked after the first 100 hours of operation, when the engine is overheating or when the fan belt is squealing.
Maintenance RPM Adjustments RPM Adjustments WARNING! Remove the blade before performing any engine service. Failure to do so may result in serious injury. Check the RPM with a tachometer after the first 20 hours of operation and every 200 hours thereafter. High-end RPM should be 3200 RPM and low-end RPM should be 1500 RPM.
