Take care when testing machine with beltguard removed to avoid loose clothing, jewelery, long hair, etc., from getting caught in rotating parts. Replace beltguard after testing and before operating machine.

• Remove beltguard
• Put machine on a rubber test mat to prevent it from moving
• Start engine and allow it to warm up
• Pull throttle to full speed. Allow the exciter to reach full speed for a few seconds, then return to idle
• Attach tachometer and slowly increase engine speed. Note the engine speed reading when clutch pulley starts to rotate. Correct clutch speed is 2300 ± 100 RPM
• If clutch engagement is below 2000 RPM, check for weak springs. If clutch engagement is over 2200 RPM, clutch may be worn and require replacement, or exciter belt may be binding
