Electrical Safety
4.
5.
6.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of electric shock if your body is grounded.
Do not expose power machines to rain or wet conditions. Water entering a power
machine will increase the risk of electric shock.
Grounded machines must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or
modify the plug in any way. Do not use any adapter plugs. Check with a qualified
electrician if you are in doubt as to whether the outlet is properly grounded. If the
machines should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user.
7.
This double insulated machine is equipped with a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician
to install a polarized outlet. Do not change the plug in any way. Double insulation
eliminates the need for the three wire grounded power cord and grounded power
supply system.
8.
9.
Do not abuse the Power Cord. Never use the Power Cord to carry the machines or
pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or
moving parts. Replace damaged Power Cords immediately. Damaged Power Cords
increase the risk of electric shock.
When operating a power machine outside, use an outdoor extension cord marked “W-
A” or “W”. These extension cords are rated for outdoor use, and reduce the risk of
electric shock.
10. Always connect the Line Cord to a Ground Fault Circuit Interrupter (GFCI) protected
electrical outlet.
Personal Safety
11. Stay alert. Watch what you are doing, and use common sense when operating a
power tool. Do not use a power tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating power machines may
result in serious personal injury.
12. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your
hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair
can be caught in moving parts.
13. Avoid accidental starting. Be sure the Power Switch is off before plugging in.
Plugging in power tools with the Power Switch on, invites accidents.
14. Remove adjusting keys or wrenches before turning the power machine on. A wrench
or a key that is left attached to a rotating part of the power machine may result in
personal injury.

15. Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the power tool in unexpected situations.
16. Use safety equipment. Always wear eye protection.
Machine Use and Care
17. Do not force the machine. Use the correct machine for your application. The correct
machine will do the job better and safer at the rate for which it is designed.
18. Do not use the power machine if the Power Switch does not turn it on or off. Any
machine that cannot be controlled with the Power Switch is dangerous and must be
replaced.
19. Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the machine. Such preventive safety
measures reduce the risk of starting the machine accidentally.
20. Store idle machines out of reach of children and other untrained persons. Machines
are dangerous in the hands of untrained users.
21. Maintain machines with care. Keep cutting tools sharp and clean. Properly
maintained tools with a sharp cutting edge are less likely to bind and are easier to
control. Do not use a damaged machine. Tag damaged machines “Do not use” until
repaired.
22. Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the machine’s operation. If damaged, have the machine
serviced before using. Many accidents are caused by poorly maintained machines.
23. Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when used on
another tool.
Service
24. Machine service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
25. When servicing a machine, use only identical replacement parts. Follow instructions
in the “Inspection, Maintenance, And Cleaning” section of this manual. Use of
unauthorized parts or failure to follow maintenance instructions may create a risk of
electric shock or injury.

GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualfified electrician if you are in doubt as to whether the
outlet is properly grounded. Do not modify the power cord plug provided with
the tool. Never remove the grounding prong from the plug. Do not use the tool if
the power cord or plug is damaged. If damaged, have it repaired by a service
facility before use. If the plug will not fit the outlet,have a proper outlet installed
bya qualified electrician.
Double Insulated Tools: Tools with Two Prong Plugs
This Sewing Machine comes with a two-prong plug, and the electrical components inside
are double insulated for safety.
1.
Tools marked “Double Insulated” do not require grounding. They have a special double
insulation system which satisfies OSHA requirements and complies with the
applicable standards of Underwriters Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code.
5.
Double insulated tools may be used in either of the 120 volt outlets shown below.
EXTENSION CORDS
1.
Grounded tools with a three-prong plug require a three wire extension cord. Double
Insulated tools can use either a two or three wire extension cord.
2.
As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a serious
drop in voltage, resulting in loss of power and possible tool damage. (See Table on
page 7.)
3.
4.
The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
When using more than one extension cord to make up the total length, make sure
each cord contains at least the minimum wire size required.
SKU 90715
Page 7

5.
If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size. (See Table
below.)
6.
7.
If you are using an extension cord outdoors, make sure it is marked with the suffix “W-
A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified electrician
before using it.
8.
Protect your extension cords from sharp objects, excessive heat, and damp or wet
areas.
