RPM Adjustments
WARNING!
Remove the blade before performing any
engine service. Failure to do so may result in serious injury.
Check the RPM with a tachometer after the first 20 hours of operation and every 200
hours thereafter.
See Table 2-1.
Before checking the RPM, make sure belt and brake strap tensions are correct (See Saw-
mill Maintenance). Also check oil, fuel, and coolant levels.
Make sure the throttle cable does not affect the engine RPM when the clutch handle is
disengaged. Make sure the cable is not bent or kinked.
1.
Use the bottom threaded cable mount to adjust the throttle cable. When the clutch handle
is disengaged, the throttle cable should be taut but the spring not extended. When the
clutch handle is engaged, the throttle spring should extend 1/8" to 1/4". Once the throttle
cable is adjusted properly, use the adjustments provided on the engine to adjust the
engine RPM (3200[+0, -100] high-end, 1500[±100] idle).
CAUTION!
Do not extend the throttle spring over 1/4".
Excessive tension may cause the throttle cable to fail pre-
maturely.
