INTERMEDIATE CHAIN TENSION ADJUSTMENT
FIGURE 39
The intermediate chain must be kept tight at all
times. Regularly check chain play and adjust if nec-
essary. The chain play should not exceed 1/4” (6
mm). This measure must be taken in the center of
the chain. Check chain play after the first hour of
operation and at the end of the season (or after 40
hours of operation).
To tighten the chain, simply loosen nut (item 1) and
then move the sprocket until the chain is tight. Tight-
en nut (item 1).
