REMARK
Check each pulley for damage, wear of the V-groove, and wear of the V-belt. In particular, be sure to check
that the V-belt is not touching the bottom of the V-groove.
If any pulley is defective, ask your Komatsu distributor to replace it.
If any belt has stretched and there is no allowance for adjustment, or if there are cuts or cracks on any belt,
replace both belts at the same time.
When adjusting the V-belt, do not push the tension pulley directly with a steel bar, etc., but put a wood piece,

After replacing the V-belt, operate for 1 hour, then check and adjust the belt tension again.
