GENERAL SAFETY
KNOW YOUR POWER TOOL. Read the owner’s manual
carefully. Learn the tool’s applications, work capabilities,
and its specic potential hazards.
4. AVOID A DANGEROUS WORKING ENVIRONMENT.
DO NOT use electrical tools in a damp environment or
expose them to rain.
BEFORE USING YOUR MACHINE
To avoid serious injury and damage to the tool, read and
follow all of the Safety and Operating Instructions before
operating the machine.
1. Some dust created by using power tools contains
chemicals known to the State of California to cause cancer,
birth defects, or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
• masonry products.
• Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area and work
with approved safety equipment, such as those dust masks
that are specially designed to lter out microscopic
particles.
2. READ the entire Owner’s Manual. LEARN how to use
the tool for its intended applications.
3. GROUND ALL TOOLS. If the tool is supplied with a 3
prong plug, it must be plugged into a 3-contact electrical
receptacle. The 3rd prong is used to ground the tool and
provide protection against accidental electric shock. DO
NOT remove the 3rd prong. See Grounding Instructions
on the following pages.
5. DO NOT use electrical tools in the presence of
ammable liquids or gasses.
6. ALWAYS keep the work area clean, well lit, and
organized. DO NOT work in an environment with oor
surfaces that are slippery from debris, grease, and wax.
7. KEEP VISITORS AND CHILDREN AWAY. DO NOT
permit people to be in the immediate work area,
especially when the electrical tool is operating.
8. DO NOT FORCE THE TOOL to perform an operation
for which it was not designed. It will do a safer and

SAFETY INSTRUCTIONS
12. KEEP PROTECTIVE GUARDS IN PLACE AND IN
WORKING ORDER.
13. AVOID ACCIDENTAL STARTING. Make sure that
the power switch is in the “OFF” position before plugging
in the power cord to the electrical receptacle.
14. REMOVE ALL MAINTENANCE TOOLS from the
immediate area prior to turning “ON” the machine.
15. USE ONLY RECOMMENDED ACCESSORIES. Use
of incorrect or improper accessories could cause serious
injury to the operator and cause damage to the tool. If in
doubt, check the instruction manual that comes with that
particular accessory.
16. NEVER LEAVE A RUNNING TOOL UNATTENDED.
Turn the power switch to the “OFF” position. DO NOT
leave the tool until it has come to a complete stop.
17. DO NOT STAND ON A TOOL. Serious injury could
result if the tool tips over, or you accidentally contact the

18. DO NOT store anything above or near the tool where
anyone might try to stand on the tool to reach it.
19. MAINTAIN YOUR BALANCE. DO NOT extend
yourself over the tool. Wear oil resistant rubber soled
shoes. Keep oor clear of debris, grease, and wax.
25. ALWAYS WEAR A DUST MASK TO PREVENT
INHALING DANGEROUS DUST OR AIRBORNE
PARTICLES, including wood dust, crystalline silica dust
and asbestos dust. Direct particles away from face and
body. Always operate tool in well ventilated area and
provide for proper dust removal. Use dust collection
system wherever possible. Exposure to the dust may
cause serious and permanent respiratory or other injury,
including silicosis (a serious lung disease), cancer, and
death. Avoid breathing the dust, and avoid prolonged
contact with dust. Allowing dust to get into your mouth
or eyes, or lay on your skin may promote absorption of
harmful material. Always use properly tting NIOSH/OSHA
approved respiratory protection appropriate for the dust
exposure, and wash exposed areas with soap and water.
26. USE A PROPER EXTENSION CORD IN GOOD
CONDITION. When using an extension cord, be sure to
use one heavy enough to carry the current your product
will draw. The table on the following page shows the correct size to use depending on cord length and nameplate
amperage rating. If in doubt, use the next heavier gauge.
The smaller the gauge number, the larger diameter of the
extension cord. If in doubt of the proper size of an extension cord, use a shorter and thicker cord. An undersized
cord will cause a drop in line voltage resulting in a loss of
power and overheating.
USE ONLY A 3-WIRE EXTENSION CORD THAT HAS
A 3-PRONG GROUNDING PLUG AND A 3-POLE
RECEPTACLE THAT ACCEPTS THE TOOL’S PLUG.
20. MAINTAIN TOOLS WITH CARE. Always keep tools
clean and in good working order. Keep all blades and tool
bits sharp, dress grinding wheels and change other
abrasive accessories when worn.
21. EACH AND EVERY TIME, CHECK FOR DAMAGED
PARTS PRIOR TO USING THE TOOL. Carefully check
all guards to see that they operate properly, are not damaged, and perform their intended functions. Check for
alignment, binding or breaking of moving parts. A guard
or other part that is damaged should be immediately
repaired or replaced.
22. DO NOT OPERATE TOOL WHILE TIRED, OR
UNDER THE INFLUENCE OF DRUGS, MEDICATION
OR ALCOHOL.
23. SECURE ALL WORK. Use clamps or jigs to secure
the work piece. This is safer than attempting to hold the
work piece with your hands.

SAFETY INSTRUCTIONS
ELECTRICAL SAFETY
THIS TOOL MUST BE GROUNDED
WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides the path of least resistance for electric
current and reduces the risk of electric shock. This tool
is equipped with an electric cord that has an equipment
grounding conductor and requires a grounding plug (not
included). The plug MUST be plugged into a matching electrical receptacle that is properly installed and grounded in
accordance with ALL local codes and ordinances.
DO NOT MODIFY ANY PLUG. If it will not t the electrical
receptacle, have the proper electrical receptacle installed
by a qualied electrician.
IMPROPER ELECTRICAL CONNECTION of the
equipment grounding conductor can result in risk of
electric shock. The conductor with the green insulation
(with or without yellow stripes) is the equipment grounding conductor. DO NOT connect the equipment grounding
conductor to a live terminal if repair or replacement
of the electric cord or plug is necessary.
EXTENSION CORDS
THE USE OF AN EXTENSION CORD
WITH THIS MACHINE IS NOT RECOMMENDED. For
best power and safety, plug the machine directly into a
dedicated, grounded electrical outlet that is within the
supplied cord length of the machine.
If and extension cord needs to be used, it should only
be for a limited operation of the machine. The extension cord should be as short as possible in length, and
have a minimum gauge size of 14AWG.
Check extension cords before each
use. If damaged replace immediately. Never use a tool
with a damaged cord, since touching the damaged
area could cause electrical shock, resulting in serious
injury.
Use a proper extension cord. Only use cords listed by
Underwriters Laboratories (UL). Other extension cords can
cause a drop in line voltage, resulting in a loss of power
and overheating of tool. When operating a power tool outdoors, use an outdoor extension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce the risk
of electric shock.
CHECK with a qualied electrician or service personnel if
you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded when installing or replacing a plug.
USE ONLY A 3-WIRE EXTENSION CORD THAT HAS
THE PROPER TYPE OF A 3-PRONG GROUNDING PLUG
THAT MATCHES THE MACHINE’S 3-PRONG PLUG AND
ALSO THE 3-POLE RECEPTACLE THAT ACCEPTS THE
TOOL’S PLUG. *
REPLACE A DAMAGED OR WORN CORD
IMMEDIATELY.
This tool is intended for use on a circuit that has an
electrical receptacle as shown in FIGURE A. It shows a
3-wire electrical plug and electrical receptacle that has
a grounding conductor. If a properly grounded electrical
receptacle is not available, an adapter as shown in
FIGURE B can be used to temporarily
connect this plug to a 2-contact ungrounded
receptacle. The adapter has a rigid lug
extending from it that MUST be connected
to a permanent earth ground, such as a
properly grounded receptacle box.
THIS ADAPTER IS PROHIBITED IN
CANADA.
FIG. A
Keep the extension cord clear of
the working area. Position the cord so that it will not
get caught on lumber, tools or other obstructions while
you are working with your power tool.
* Canadian electrical codes require extension cords
to be certied SJT type or better.
** The use of an adapter in Canada is not acceptable.
