9. USE PROPER EXTENSION CORD.
Make sure your extension cord is
in good condition. When using an
extension cord, be sure to use one
heavy enough to carry the current
your product will draw. An undersized
cord will cause a drop in line voltage
resulting in loss of power and over-
heating. Table A shows the correct
size to use depending on cord length
and nameplate ampere rating. If in
doubt, use the next heavier gauge.
The smaller the gauge number, the
heavier the cord.
16. REDUCE THE RISK OF UNINTEN-
TIONAL STARTING. Make sure
switch is in off position before plug-
ging in.
17. USE RECOMMENDED ACCESSO-
RIES. Consult the owner’s manual for
recommended accessories. The use
of improper accessories may cause
risk of injury to persons.
18. NEVER STAND ON TOOL. Serious
injury could occur if the tool is tipped
or if the cutting tool is unintentionally
contacted.
10. WEAR PROPER APPAREL. Do not
wear loose clothing, gloves, neck-
ties, rings, bracelets, or other jewelry
which may get caught in moving
parts. Nonslip footwear is recom-
mended. Wear protective hair cover-
ing to contain long hair.
19. CHECK DAMAGED PARTS. Before
further use of the tool, a guard or
other part that is damaged should
be carefully checked to determine
that it will operate properly and per-
form its intended function – check for
alignment of moving parts, binding
of moving parts, breakage of parts,
mounting, and any other conditions
that may affect its operation. A guard

structions discussed in this instruction
manual cannot cover all possible con-
ditions and situations that may occur.
It must be understood by the operator
that common sense and caution are
factors which cannot be built into this
product, but must be supplied by the
operator.
15. Avoid unintentional starting. Prepare
to begin work before turning on the
tool.
16. People with pacemakers should
consult their physician(s) before use.
Electromagnetic fields in close prox-

Vibration Safety
This tool vibrates during use. Re-
peated or long-term exposure to
vibration may cause temporary or
permanent physical injury, particularly
to the hands, arms and shoulders. To
reduce the risk of vibration-related
injury:
17. WARNING: Some dust created by
power sanding, sawing, grinding, drill-
ing, and other construction activities,
contains chemicals known [to the
State of California] to cause cancer,
birth defects or other reproductive
harm. Some examples of these
chemicals are:
1. Anyone using vibrating tools regu-
larly or for an extended period should
first be examined by a doctor and
then have regular medical check-
ups to ensure medical problems are
not being caused or worsened from
use. Pregnant women or people
who have impaired blood circulation
to the hand, past hand injuries, ner-
vous system disorders, diabetes, or
• Lead from lead-based paints
• Crystalline silica from bricks and ce-
ment or other masonry products
• Arsenic and chromium from chemi-
cally treated lumber
Your risk from these exposures var-
ies, depending on how often you do
this type of work. To reduce your
exposure to these chemicals: work in

Raynaud’s Disease should not use
this tool. If you feel any medical or
physical symptoms related to vibra-
tion (such as tingling, numbness, and
white or blue fingers), seek medical
advice as soon as possible.
2. Do not smoke during use. Nico-
tine reduces the blood supply to the
hands and fingers, increasing the risk
of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice between dif-
ferent processes.
5. Include vibration-free periods each
day of work.
6. Grip tool as lightly as possible (while
still keeping safe control of it). Let
the tool do the work.
7. To reduce vibration, maintain the tool
as explained in this manual. If any
abnormal vibration occurs, stop use
immediately.
