REPLACING/REPAIRING

Drive Belts

Raise the body and inspect the condition of the four

(4)drive belts after every 25 hours of operation -- engine/PTO drive and ground drive. If the belts show signs of cracking or deteriorating, the belts should be replaced. Refer to REPLACING/REPAIR- ING the Drive Belts in this section.

Spark Plugs

Every 200 hours, remove the spark plugs, inspect, clean, and reset the gap (or replace with a new plug). Clean spark plug with a wire brush. If the electrodes are burned short or pitted, replace the plug (refer to Specifications for the proper type of replacement plug). Check the spark plug gap with a wire-type feeler gauge and set the gap to 0.030 in. (0.76 mm). Reinstall and tighten to 18 ft-lb (24.4 N·m). Both spark plugs should be replaced yearly.

Fuel Lines and Clamps

Every year, inspect the fuel lines from the tanks to engine for deterioration or damage. Also, inspect the fuel line clamps for tightness. Good preventive maintenance calls for complete replacement of fuel lines and clamps every two (2) years.

Blade Brake Action

WARNING

It is important to check and maintain blade brake action for safe operation of the ma- chine.

Check the function of the cutter blade brake by engaging the blade clutch (PTO), operating the engine at full throttle, then disengaging the clutch and measuring how quickly the blades stop. Watch the rotation of the blade drive shaft as a visual indication that movement has stopped. If the brake is working properly, all rotation will stop five (5) seconds after disengagement of the clutch. If the brake system malfunctions -- blades do not stop in five (5) seconds -- repair the brake before operating the mower.

REPLACING/REPAIRING

DANGER

To prevent accidental starting of the engine when replacing parts or repairing the machine, remove the key from the ignition switch and disconnect the spark plug wires.
