General Pottery Wheel Safety
Warnings
WARNING Read all safety
warnings and instructions.
Failure to follow the warnings and
instructions may result in electric
shock, re and/or serious injury.
Save all warnings and
instructions for future reference.
Work area safety1.
Keep work area clean and well lit.a.
Cluttered or dark areas invite acci-
dents.
Do not operate Pottery Wheel inb.
explosive atmospheres, such as in
the presence of ammable liquids,
gases or dust. Electrical products
create sparks which may ignite the
dust or fumes.
Keep children and bystandersc.
away while operating a Pottery
Wheel. Distractions can cause you
to lose control.
Electrical safety2.
Electrical plugs must match thea.
outlet. Never modify the plug in
any way. Do not use any adapter
plugs. Unmodied plugs and match-
ing outlets will reduce risk of electric
shock.
SKU 98250 For technical questions, please call 1-800-444-3353. Page 3
Avoid body contact with groundedb.
surfaces such as pipes, radiators,
ranges and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
Do not abuse the cord. Never usec.
the cord for carrying, pulling or un-
plugging the Pottery Wheel. Keep
cord away from heat, oil, sharp
edges or moving parts. Damaged
or entangled cords increase the risk
of electric shock.
When operating a Pottery Wheeld.
outdoors, use an extension cord
suitable for outdoor use. Use of a
cord suitable for outdoor use reduces
the risk of electric shock.
If operating a Pottery Wheel in ae.
damp location is unavoidable, use
a Ground Fault Circuit Interrupter
(GFCI) protected supply. Use of
a GFCI reduces the risk of electric
shock.
Personal safety3.
Stay alert, watch what you are do-a.
ing and use common sense when
operating a Pottery Wheel. Do
not use a Pottery Wheel while you
are tired or under the inuence of
drugs, alcohol or medication. A
moment of inattention while operating
Pottery Wheels may result in serious
personal injury.
Use personal protective equip-b.
ment. Always wear eye protection.
Safety equipment such as dust mask,
or hearing protection used for appro-
priate conditions will reduce personal
injuries.
Remove any adjusting key orc.
wrench before turning the Pot-
tery Wheel on. A wrench or a key
left attached to a rotating part of the
Pottery Wheel may result in personal
injury.
Do not overreach. Keep properd.
footing and balance at all times.
This enables better control of the Pot-
tery Wheel in unexpected situations.
Dress properly. Do not wear loosee.
clothing or jewelry. Keep your
hair, clothing and gloves away
from moving parts. Loose clothes,
jewelry or long hair can be caught in
moving parts.
If devices are provided for the con-f.
nection of dust extraction and col-
lection facilities, ensure these are
connected and properly used. Use
of these devices can reduce dust-
related hazards.
Only use safety equipment thatg.
has been approved by an appropri-
ate standards agency. Unapproved
safety equipment may not provide
adequate protection. Eye protection
must be ANSI-approved and breath-
ing protection must be NIOSH-ap-
proved for the specic hazards in the
work area.
Pottery Wheel use and care4.
Do not force the Pottery Wheel.a.
Use the correct Pottery Wheel
for your application. The correct
Pottery Wheel will do the job better
and safer at the rate for which it was
designed.
Do not use the Pottery Wheel if theb.
switch does not turn it on and off.
Any Pottery Wheel that cannot be
controlled with the switch is danger-
ous and must be repaired.
Disconnect the plug from the pow-c.
er source before making any ad-

the reach of children and do not
allow persons unfamiliar with the
Pottery Wheel or these instruc-
tions to operate the Pottery Wheel.
Pottery Wheels are dangerous in the
hands of untrained users.
Maintain Pottery Wheels. Checke.
for misalignment or binding of
moving parts, breakage of parts
and any other condition that may
affect the Pottery Wheel’s opera-
tion. If damaged, have the Pottery
Wheel repaired before use. Many
accidents are caused by poorly main-
tained Pottery Wheels.
Use the Pottery Wheel, acces-f.
sories and tool bits etc. in ac-
cordance with these instructions,
taking into account the working
conditions and the work to be per-
formed. Use of the Pottery Wheel
for operations different from those
intended could result in a hazardous
situation.
Service6.
Have your Pottery Wheel serviceda.
by a qualied repair person using
only identical replacement parts.
This will ensure that the safety of the
Pottery Wheel is maintained.

GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM
INCORRECT GROUNDING
WIRE CONNECTION:
Check with a qualied
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
t the outlet, have a proper
outlet installed by a qualied
electrician.
SKU 98250 For technical questions, please call 1-800-444-3353. Page 6
Grounded Tools: Tools with Three
Prong Plugs
Tools marked with “Grounding Re-1.
quired” have a three wire cord and
three prong grounding plug. The
plug must be connected to a properly
grounded outlet. If the tool should
electrically malfunction or break
down, grounding provides a low
resistance path to carry electricity
away from the user, reducing the risk
of electric shock. (See 3-Prong Plug
and Outlet.)
The grounding prong in the plug is2.
connected through the green wire in-
side the cord to the grounding system
in the tool. The green wire in the cord
must be the only wire connected to
the tool’s grounding system and must
never be attached to an electrically
“live” terminal. (See 3-Prong Plug
and Outlet.)
The tool must be plugged into an3.
appropriate outlet, properly installed
and grounded in accordance with all
codes and ordinances. The plug and
outlet should look like those in the
preceding illustration. (See 3-Prong
Plug and Outlet.)
Double Insulated Tools: Tools
with Two Prong Plugs
Tools marked “Double Insulated” do1.
not require grounding. They have
a special double insulation system
and complies with the applicable
-
tories, Inc., the Canadian Standard
Association, and the National Electri-
cal Code. (See Outlets for 2-Prong
Plug.)
Double insulated tools may be used2.
in either of the 120 volt outlets shown
in the preceding illustration. (See
Outlets for 2-Prong Plug.)
Extension Cords
Grounded1. tools require a three wire
extension cord. Double Insulated
tools can use either a two or three
wire extension cord.
As the distance from the supply outlet2.
increases, you must use a heavier
gauge extension cord. Using exten-
sion cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and pos-
sible tool damage.
(See Table A.)
SKU 98250 For technical questions, please call 1-800-444-3353. Page 7
The smaller the gauge number of the3.
wire, the greater the capacity of the
cord. For example, a 14 gauge cord
can carry a higher current than a 16
gauge cord. (See Table A.)
When using more than one exten-4.
sion cord to make up the total length,
make sure each cord contains at
least the minimum wire size required.
(See Table A.)
If you are using one extension cord5.
for more than one tool, add the
nameplate amperes and use the sum
to determine the required minimum
cord size. (See Table A.)
If you are using an extension cord6.
