 RUN MACHINE AT
RECOMMENDED SPEED
1. Run new machine at a 20% less speed
than maximum for the first 4 weeks.
At the end of 4 weeks, original oil
should be drained out and replaced.
Thereafter the machine may be oper
ated at normal speed.
2. Keep enough amount of oil in the ma
chine; the top of Oil Level Indicator O
should be always between the two lines
of Oil Level Sight Window. See page
12.
3. While machine running, Oil Monitor©
is green, which shows the normal oil
circulation inside the machine. If Oil
Monitor © is red, something ex
traordinary may be caused in the oil
circulation; check the oil amount or
Oil Filter. See page 12.
4. Before starting machine for the first
time, or if machine is idle for more
than two weeks, manually lubricate
Needle Holder Guide Stud O, Upper
Looper Holder © and the oil hole ©.
The Oil Hole © requires daily lubrica
tion before morning start.
