LUBRICATION Wheel and Deck Zerks Use only good quality bearing grease. Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality. Front Wheel Mount Remove dust cap to expose zerk. Lubricate with a grease gun until the grease is forced out around the top washer. Front Wheel Bearings Lubricate 3-4 strokes with a grease gun on each set of wheel bearings. Cables If possible, grease both ends of the cables and move the controls to end stop positions when lubricating. Refit the rubber covers on the cables after lubrication. Cables with sheaths will bind if they are not lubricated regularly. If a cable binds, it can disrupt operation. If a cable binds, remove the cable and hang it vertically. Lubricate it with light engine oil until the oil begins to escape from the bottom. Lubricating front wheels Hydraulic Drive Fluid and Filter Change The hydraulic drive is designed with an external filter for ease of maintenance.

Place an oil drain pan with a 2 gallon capacity beneath the oil reservoir. Remove the drain port and drain oil. Remove the oil filter from the pump.
