Service and Repairs Cooling System To ensure proper engine cooling, make sure the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times. NOTE: Perform this maintenance procedure at the interval specified in the Operator’s Manual. IMPORTANT: The engine that powers the Multi Pro is air–cooled. Operating the engine with dirty or plugged cooling fins, a blocked grass screen, or a plugged or dirty blower housing will result in engine overheating and engine damage. 1. Park machine on a level surface, stop engine, engage parking brake, and remove key from the ignition switch. Kohler Gasoline Engine IMPORTANT: Never clean engine with pressurized water. Water could enter and contaminate the fuel system. 2 2. Clean cooling fins on both cylinder heads. 3. Clean grass screen and blower housing of dirt and debris (Fig. 4). Remove screen and housing if necessary. IMPORTANT: Never operate engine without the blower housing installed. Overheating and engine damage will result. Figure 4 1. Grass screen 2. Blower housing 1 4. Make sure grass screen and blower housing are reinstalled to the engine if removed. Multi Pro 1200/1250 Page 3 – 5 Kohler Gasoline Engine
