HAPPY Industrial Corporation

# For safe adjustment and repair #
In order to conduct adjustment and repair safely and surely,
please b42e 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.

3-1-3 Selection of thread
1. Selection of upper thread.

Please select considering cloth, design of pattern and flavour etc.

Please refer to [Relation between needle and upper thread 3-1-4].

Z twisted thread is to be used.
(As rotary hook turns left- wise, Z twisted thread can prevent loosening of twist)

Z-twisted

S-twisted

(Left - twisted)

(Right - twisted)

2. Selection of lower thread.
Basically please use cotton thread (#80-120), #120 is recommendable.
Pay attention to the following in selection.
# Thickness should be equal.
# When it is lightly stretched. it doesn't break easily.
# In process of time, it doesn't get inferior.

Commercially available paper bobbin can be used, but please select thread with
thickness corresponding to cotton thread (#80-120).

3-1-4 Relation between needle and upper thread
1. Description of needle
Basically please use [DB X K5] in standard accessory.

If description or thickness of cloth doesn't suit needle size, poor sewing finish / thread break / skipping will occur.
Therefore careful attention is required in selecting needle.

2. Relation between needle and upper thread will be found below. (Representative example is shown.)
Needle - Size is [German 75] in standard accessory.
If necessary, please select in accordance with description of thread and cloth.
Thread - In case needle size is [German 75], if thread is rayon,[#120] is recommendable.
