E) Openers down-pressure adjustment
1)
Adjustment of openers down-force load is achieved by
a rocking arm with two possible load positions.
Maximum down-force load: frontwards
(Picture 19-A)
Minimum down-force load: backwards (A socket wrench
should be used to carry out the change)
(Picture 20).
Too much down-force load may increase parts
wear and drive resistance.
