CARE AND MAINTENANCE - MODEL 502 Page 20 LUBRICATION: CHASSIS AND MOWER DECK: LOCATIONS: SERVICE INTERVALS: RECOMMENDED GREASE: Number of grease zerks used (2) (1) each front wheel caster Every (50) hours of operation Name brand wheel bearing or multi-purpose grease CAUTION: The use of compressed air pressure greasing methods is not recommended as damage to seals and bearings could occur.
Page 21 CARE AND MAINTENANCE - MODEL 502 CLEANING THE MOWER: A clean machine is a source of pride to the owner. However, cleaning by use of high pressure commercial washes is not recommended. The high water pressure, combined with solvents or alkaline detergents, can lead to corrosion of electrical components or damage to the sealed bearings used on your mower. A better approach is the use of mild household soaps and low water pressure. A stiff brush can be used to loosen excess grass and dirt build up.
Page 22 TROUBLE SHOOTING MOWER CUT QUALITY: There are many variables that can effect the cut quality of any multi blade mower. Type and condition of grass, ground speed, blade speed, and conditions are some of the variables that interact creating differences in cut quality results. In most cases, a smooth, even cut will be achieved without further adjustment. The Trouble Shooting Chart suggests practices and adjustments that may be helpful in improving cut quality.
