# For safe adjustment and repair #
In order to conduct adjustment and repair safely and surely,

please be sure to abide by what is mentioned in this manual to prevent trouble.
1. When you conduct adjustment and repair of this embroidery machine or handle electric related parts,
you are required to take technical lesson in advance.
2. When you conduct adjustment and repair using this manual, please be sure to use together with instruction
with it in hand.
# Please conduct in accordance with work process in this manual.

# In case there are no specific instructions or explanations in work process.
please be sure to unplug cord from receptacle.
# When you exchange parts, please be sure to use genuine parts designated by us.
# Please never remodel the embroidery machine.
When you handle circuit boards:

# In order to prevent troubles from static electricity, please remove earth from human body.
# Please don't touch metal part of circuit board with bare hand as it will short-circuit
and threaten to break circuit boards.
# When you removed circuits boards from the machine or you store or transport them,
please wrap them in static electricity preventive bag and avoid to give shock.
