While tightening the belts proceed as follows:
-
Check up tension of new belts after first 5 service hours and afterwards always in
intervals of 50 hours. Excessive slipping will wear the belts and the pulleys out
prematurely. Excessive tension reduces belt life essentially. It brings also negative
impact on optimal alignment of pulleys.
-
1 – driving pulley on
engine
2 – pulley on cutting
head shaft
3 – straight-edge rule
-
Align the pulleys
(their faces) by means of a straight-edge rule starting as from the lay-shaft pulley, go on
to the engine driving pulley and finally to the cutting head pulley. Max.
inclination/deflection allowed should be less than 1 mm. If this inclination found
between the driving pulley (engine) and the driven pulley (cutting head) exceeds this
limit value, proceed as follows:
-
