Check Belt Tension
Belt tension may decrease over time. It must be adjusted
within the first half hour of operation and 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. To check and adjust the forward 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 spring when in its relaxed state.
4. Pull down on drive safety control lever and measure
length of spring when compressed. Ideal length would
be 1/4” shorter. See FIGURE 6 and instruction in the
Controls Section of this manual.
