9. MAINTENANCE
Before maintenance, switch the machine off.
Not doing so could cause an injury.
CLEANING
1. Open front cover and side cover.
2. Remove thread waste and dust with a cleaning
brush (Optional accessory).
LUBRICATION
Lubrication is not necessary for this machine
since the important parts are all made of a special
oil impregnated sintered metal. However, one
or two drops of oil at the oiling point shown will
increase durability.
Note 1: If too much oil is applied it could cause
trouble such as dirty thread or fabric, or
sewing malfunctions. Keep to this small
amount.
Note 2: Use the oil supplied with your machine
or special oil for sewing machines. Other
oils could cause mechanical problems.
