Precautions to be taken so as to use the MF-3620 more safely
1. To prevent accidents caused by electric shock, never open the motor control box
cover or touch the components inside the control box while the power switch is ON.
1. Never bring your fi ngers under the needle when the power switch is turned ON or
the machine is in operation.
2. Never bring your fi ngers, hair or clothes close to the pulley and needle or place any-
thing on the pulley and under the needle while the machine is in operation.
3. Never operate the machine with the safety devices such as belt cover, needle bar
thread take-up cover, fi nger guard, eye guard cover, etc. removed.
4. Be sure to turn OFF the power and perform the work after ascertaining that the sewing
machine does not run even when the starting pedal is depressed in case of checking,
adjusting, cleaning, threading or replacing the needle of the sewing machine.
5. Never operate the sewing machine with the ground wire for the power supply re-
moved so as to ensure safety.
6. Be sure to turn OFF the power switch in advance in case of inserting/removing the
power plug.
7. In time of thunder and lightning, stop your work and disconnect the power plug from
the receptacle so as to ensure safety.
8. When you move the sewing machine from a cold place directly to a warm place, dew
condensation may result. Turn ON the power to the machine after you have con-
fi rmed that there is no fear of dew condensation.
9. In case of maintenance, inspection, or repair, be sure to turn OFF the power switch
and confi rm that the sewing machine and the motor have completely stopped before
starting the work. (In case of the clutch motor, it continues rotating for a while by the
inertia even after turning OFF the power switch. So, be careful.)
10. Be careful of handling this product so as not to pour water or oil, shock by dropping,
and the like since this product is a precision instrument.
