GROUNDING INSTRUCTIONS  
This product must be grounded. In the event of malfunction or breakdown, grounding provides a path of least  
resistance for electric current to reduce the risk of electric shock.  
This product is equipped with a cord having an equipment grounding conductor and a grounding plug.  
The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with  
all local codes and ordinances.  
DANGER  
Improper connection of the equipment-grounding conductor can result in a risk of  
electric shock.  
1. The conductor with insulation having an outer surface that is green with or without yellow stripes is the  
equipment-grounding conductor.  
2. If repair or replacement of the cord or plug is necessary, do not connect the equipment-grounding  
conductor to a live terminal.  
3. Check with a qualified electrician or serviceman if the grounding instructions are not completely  
understood, or if in doubt as to whether the product is properly grounded.  
Do not modify the plug provided with the product if it will not fit the outlet, have a proper outlet installed by  
a qualified electrician.  
4. This product is for use on a nominal 120 V circuit, and has a grounding plug that looks like the plug illustrated  
in Fig. A. A temporary adaptor, which looks like the adaptor illustrated in Fig. C, may be used to connect this  
plug to a 2-pole receptacle as shown in Fig B. If a properly grounded outlet is not available, the temporary  
adapter should be used only until a properly grounded outlet can be installed by a qualified electrician.  
The green colored rigid ear, lug, and the like, extending from the adaptor must be connected to a permanent  
ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place  
by the metal screw.

Bobbin Threads  
Cotton or spun rayon threads sizes 80 to 120 (74 to  
100 dtex/2) are recommended for bobbin thread.  
Do not use poor quality prewound bobbins.  
Needles  
Use the DB x K5Q1-NY, size 11 needles (Janome part  
number 770811000).  
Stabilizers  
To obtain the best quality embroidery, it is important to  
use stabilizers.  
Types of stabilizer  
Tear-away stabilizer:  
Use tear-away stabilizers for stable woven fabrics.  
Iron-on stabilizer:  
Fuse it to the wrong side of the fabrics with an iron.  
Cut-away stabilizer:  
Use cutaway stabilizers for knits and all kinds of  
unstable fabrics.  
Adhesive (Iron-on) Stabilizer  
Place the Wrong side of fabric and the glossy side  
of the stabilizer together. Fold up a corner of the  
stabilizer and fuse it with an iron.  
Water soluble stabilizer:  
Use this stabilizer for cutwork or lace embroidery, and  
also for the right side of looped fabrics such as  
towelling to avoid loops coming through the  
embroidery.  
NOTES:  
Fold up a corner of the stabilizer, to make it  
easier to peel off the excess stabilizer after  
stitching.  
Sticky stabilizer:  
Ironing temperatures vary depending on kind of  
adhesive type stabilizer.  
This stabilizer is a sticky paper used for securing a  
small fabric or work that cannot be secured in the  
hoop.  
It is also used for velvet and other napped fabric that  
would be permanently marked by the hoop.  
Usage:  
The stabilizer should be attached to the wrong side  
of fabric.  
More than one layer may be required.  
Felt or stable fabrics do not need to be stabilized  
and you may embroider directly on them.  
For firm fabrics, you may place a thin paper under  
the fabric.  
The non-adhesive type should be used when  
embroidering fabric, which cannot be ironed or for  
sections, which are difficult to iron.  
Cut the stabilizer larger than the embroidery hoop  
and set it on the hoop so that the entire piece is  
fastened within the hoop to prevent looseness of the  
fabric.
