Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Before each use or daily Every 50 hours Maintenance Procedure • Check the blade stopping time. • Grease the bearings If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.
Each cutting deck has two grease fittings per rear roller. If the machine is operated under normal conditions, lubricate rear roller bearings (Figure 9) with No. 2 general purpose lithium base grease or molybdenum base grease, after every 50 hours of operation. G011349 Figure 11 Figure 9 1. Lynch pin Important: Make sure the grease groove in each roller mount aligns with the grease hole in each end of the roller shaft.
4. Position the cutting edge of the marked end of the blade at 12 o’clock (straight ahead in the direction of mowing) (Figure 12) and measure height from table to cutting edge of blade. 12:00 3:00 9:00 Figure 13 6:00 Figure 12 1.

If the blade is allowed to wear, a slot will form between the sail and flat part of the blade (Figure 15). Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to yourself or bystanders. 2 • Inspect the blade periodically for wear or damage. 1 G011355 • Always replace a worn or damaged blade.
