BELT MAINTENANCE

Check Belt Tension
Belt tension may decrease over time. It may need to be adjusted
within the first half hour of operation and should be checked
after every two hours of operation. Proper adjustment will
assure long belt life. Too much or too little belt tension will cause
premature belt failure.
An indication that the belt may need to be adjusted is a constant
buzzing sound that can be heard when the engagement lever is
compressed (see page 18), or a persistant squealing sound when
engaged and under load.
NOTE: A short buzzing noise can be heard when engagement
lever is released. This is normal, caused by the teeth of the
cog belt catching the wire guide, stopping the rotation of the
belt. This does not require the belt tension to be adjusted.
To check and adjust the belt tension, do as follows:
1. Turn off engine. Engine must be cool.
2. Remove spark plug wire from spark plug and secure.
3. With drive safety control lever in the neutral position,
measure length of the cable spring when in its relaxed state.
4. Pull down on drive safety control lever and measure length of
spring when extended. Ideal length would be 1/4" longer. SEE
FIGURE 13
5. To adjust, SEE FIGURE 11 and Belt Tension Adjustment
instructions.
