KM-250 Series are intended to be used for industrial purposes for sewing textiles and
other similar materials. Carefully study the following instructions before operating the
machine.
Read the manual thoroughly and understand the instructions fully before use.
Put on proper safety garments.
While the machine is in motion, keep your hands or any part of your body away from
moving parts, e.g., needle, hook, thread take-up spring and pulley, etc.
Do not remove any form of safety covers while the machine is in use.
Be sure to connect the ground (earth) wire.
Before opening electric boxes such as the control box, shut down the power supply
and make sure the power switch is in off mode.
Stop the machine before threading the needle or checking after sewing work is
finished.
Never turn the power switch on with the pedal down.
Do not use the machine if the cooling fan is clogged. Clean the air filter embedded in
the control box at least once a week.
Keep the machine away from strong electromagnetic fields such as high-frequency
welding machines.
Always start the machine with safety covers in place
