■ Lubrication
WARNING!
Disconnect power cord before replacing important parts.
Any machine is generally in its best condition when delivered; therefore, it is necessary to try to keep
this condition. Unexpected failure occurs due to lack of oil, debris or dust. To keep its best condition,
periodically clean the machine and apply proper kinds of oil to each part in which lubrication is
needed.
Although the frequency of lubrication varies according to how much the machine is used, at least it
is necessary to lubricate before the machine becomes dry. It is also necessary to wipe off excessive
oil as it collects dirt.
