4-1. Method of lubrication
() Method of circulating lubrication (when the oil collected in the under cover is reused)
(2) Method of non-circulation type lubrication (when only the clean oil is always used)
Periodically (approximately once in three months) clean the aforementioned filter sections (four
places) in order to use the machine for a long time. When the filter is clogged, lubrication trouble
will occur and break-down will be caused.
In addition, when the oil becomes dirty, replace the oil gathered in the oil tank and the under cover.
Put cap
3
to inlet port for circulation
1
in the
same state as that at the time of delivery, and
securely fix it to the position where it does not
come in contact with the moving section.
* Remove drain screw
2
and dump the oil
which has dropped to the under cover.
When inlet port for circulation
1
comes
in contact with the oil surface, oil is
absorbed without passing the filter. As a
result, break-down will be caused.
In addition, when cap
3
is not inserted,
oil leakage from inlet port for circulation
1
or unstableness of oil amount in the
hook may occur.
