          CAUTION 

Enviromental Requirements 

 

Sewing 

Be sure to wear protective goggles when using the machine. If goggles are not worn, there is the danger that if      
a needle breaks, parts of the broken needle may enter your eyes and injury may result. 

Use the sewing machine in an area free from 
sources of strong electrical noise such as        
high-electrical noise may cause problems with 
correct operation. 

Any fluctuations in the power supply voltage 
should be within ± 10% of the rated voltage for 
the machine. Voltage fluctuations which are  
greater than this may cause problems with         
correct operation. 

The power supply capacity should be greater 
than the requirements for the sewing machine’s 
electrical consumption. Insufficient power supply 
capacity may cause problems with correct             
operation. 

The pneumatic delivery capability should be        
greater than the requirements for the sewing 
machine’s total air consumption. Insufficient 
pneumatic delivery capability may cause       
problems with correct operation. 

The ambient  should be within the range of 5°C to 
35°C during use. Temperatures which are lower or 
higher than this may cause problems with correct 
operation. 

The relative humidity should be within the range     
of 45% to 85% during use, and no dew formation 
should occur in any devices. Excessively dry or  
humid enviromentts and dew formation may cause 
problems with correct operation. 

Avoid exposure to direct sunlight during use.          
Exposure to direct sunlight may cause problems 
with correct operation. 

In the event of an electrical storm, turn off the power 
and disconnect the power cord from the wall outlet. 
Lightning may cause problems with correct           
operation. 

NOTES ON SAFETY 

Thank you very much for buying a sewing machine. Before using your new machine please read the safety instructions        
and the explanations given in the instruction maunal. 

With industrial sewing machines it is normal to caryy out work while positioned directly in front of moving parts such as the 
needle and thread take-up lever and consequently there is always a danger of injury that can be caused by these parts. Follow 
the instructions from training personel and instructors regarding safe and correct operation before operating the machine so 
that you will know how to uses it correctly.
