CAUTION
When threading or replacing needle, the main power and light switch of the machine must be switched off

When the machine is not in use, it is recommended that the electric supply plug is disconnected from the
wall socket to avoid any possible hazards.
Notes on the motor
- The maximum operating speed of this sewing machine is 1,300 stitches per minute, which is quite fast
compared to the normal operating speed of 300 to 800 stitches per minute for the ordinary sewing machine.
- The bearings in the main motor are made of a special material (oil-impregnated alloy mounted in felt heat-
treated with oil) that enables them to withstand long hours of continuous operation.
- Continuous operation of the sewing machine can cause heat to build in the motor area, but not enough to
adversely affect its performance. It is important to keep fabric and paper away from the air openings on the
back, sides and bottom of the machine so air can get to these openings.
- When the main motor is running, sparks can be seen through the air openings in the cover on the same side
as the handwheel. These sparks are produced by the carbon brushes and the commutator, and are part of the
machines normal operation.
