Maintenance
WARNING!
No settings or adjustments are to be made unless: Engine is stopped, key has been removed, park brake is on and bat- tery cable removed from battery.
Annual inspection and maintenance from an au- thorized Yazoo/Kees dealer is recommended to keep your machine in the best condition mechani- cally and ensures safe operation.
Engine oil
Engine oil should be checked daily before starting the machine. See the engine manufacturers manual for specifications on type of oil, filling in- structions and service intervals. FIG - 8
Mower blades
Inspect blades and sharpen or replace as needed. Check blades daily or as needed. Bent, cracked or blades with large notches in them should be replaced. Sharpen to an angle of 22 to 28 degrees. Always check the balance of the blades after sharpening to prevent excessive vibration.
Safety interlock system
Check daily and never operate the machine if the system is not functioning properly. The starter should crank only when the operator is in the seat, the parking brake is applied, blade switch off and the motion control levers in the neutral slots. If the machine starts with any of these controls in an operating position, turn the machine off and re- pair the system immediately.
Cutter Housings
Grease housings once weekly or every 40 to 50 hours of use. Use a good synthetic grease. Pump grease in until a small amount purges from the popet on the underside of the deck. Check the torque of the pulley bolt (45 ft/lbs) should be main- tained.
