5. Lubrication
Warning: Turn OFF the power before starting the work as to prevent accident caused by abrupt start of the
sewing machine.
Fill the oil tank with oil for hook lubrication before the sewing
machine.
1. Tilt the machine head until it comes in contact with the
head support rod.
2. Remove oil hole cap (1) and fill the oil tank with oiler
supplied with the machine.
3. The amount of oil should be reached up to the engraved
marker line of oil tank (2). If the oil is filled excessively, it
will leak from the air vent hole in the oil tank and proper
lubrication will be not performed. So, be careful.
4. When you operate the sewing machine, refill oil if the top
end of oil amount indicating rod (3) comes down to the
lower engraved marker line of oil amount indicating
window (4).
Caution: When you use a new sewing machine or a sewing
machine after an extended period of disuse, run your
machine at 3,000 to 3,500 rpm for the purpose o break-in.
Do not remove rubber plug (5).
6. Adjusting the amount of oil in the hook
Warning: Turn OFF the power before starting the work as to prevent accident caused by abrupt start of the
sewing machine.
Adjustment of the amount of oil in the hook is performed with
oil amount adjustment screw (1). Adjustment procedure:
Tighten (turn clockwise) oil amount adjustment screw (1) to
increase the amount of oil in the hook, or loosen (turn
counterclockwise) to decrease it.
Caution: When using RP hook (hook for dry head) for the SS
type, be sure to loosen the oil amount adjustment screw up to
the minimum so as to reduce the oil amount in the hook.
Never drain the oil in the oil tank even when RP hook (hook
for dry head) is used.
