Maintenance
3. For Autoclutch Option:
Place a wrench on the flats at the top of the turnbuckle. Use a
second wrench to turn the bottom-most jam nut clockwise (as viewed from the bottom) to
tighten the belt, counterclockwise to loosen the belt.
See Figure 3-8.
4. Gas/Diesel Engines Only
: After tensioning the drive belt, check throttle cable tension
and adjust if necessary. The throttle cable should be tensioned just enough so that the
engine revs as soon as the clutch/brake handle is engaged. The throttle linkage should
NOT affect engine RPM while the clutch/brake handle is disengaged.
NOTE:
A properly
adjusted throttle will extend the cable spring 1/4" to 3/8" (6.4 - 9.5 mm) when running and
have a slight amount of slack in the cable when idling. Always be sure to check the drive
belt support after adjusting drive belt tension.
Periodically check all belts for wear. Replace any damaged or worn belts as needed.
