of oil sprayed to the paper.
b) Perform 3 times of confirming the amount of
lubrication. The adequate adjusted amount is a
state where the maximum and minimum amounts
do not fall short of or exceed the amount shown in
the picture.

invite the hook seizure, and if the amount is too
large, it could cause a contamination by oil.
