SAFETY INSTRUCTIONS

IMPORTANT! Safety is the single most important consideration in the operation of this equipment. The following

instructions must be followed at all times.

There are certain applications for which this tool was designed. We strongly recommend that this tool not be modied and/
or used for any other application other than that for which it was designed. If you have any questions about its application,
do not use the tool until you have contacted us and we have advised you.

GENERAL SAFETY

KNOW YOUR POWER TOOL. Read the owner’s manual

carefully. Learn the tool’s applications, work capabilities,
and its specic potential hazards.

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. CALIFORNIA PROPOSITION 65
Some dust created by power sanding,

sawing, grinding, drilling 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:

- 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.

4. AVOID A DANGEROUS WORKING ENVIRONMENT.
DO NOT use electrical tools in a damp environment or
expose them to rain.

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 higher
quality job by only performing operations for which the tool
was intended.

9. WEAR PROPER CLOTHING. DO NOT wear loose
clothing, gloves, neckties, or jewelry. These items can get
caught in the machine during operations and pull the
operator into the moving parts. The user must wear a
protective cover on their hair, if the hair is long, to prevent it
from contacting any moving parts.

10. CHILDPROOF THE WORKSHOP AREA by removing
switch keys, unplugging tools from the electrical
receptacles, and using padlocks.

11. ALWAYS UNPLUG THE TOOL FROM THE
ELECTRICAL RECEPTACLE when making adjustments,
changing parts or performing any maintenance.

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.

SAFETY INSTRUCTIONS

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
tool.

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.

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 workpiece. This is safer than attempting to hold the
workpiece with your hands.

24. STAY ALERT, WATCH WHAT YOU ARE DOING,

AND USE COMMON SENSE WHEN OPERATING A
POWER TOOL.

A moment of inattention while operating power tools may
result in serious personal injury.

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.

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 a grounding plug. The plug MUST
be plugged into a matching electrical receptacle that is
properly installed and grounded in accordance with ALL
local codes and ordinances.

SAFETY INSTRUCTIONS

ELECTRICAL SAFETY (Continued)

EXTENSION CORDS

DO NOT MODIFY THE PLUG PROVIDED.

If it will not t the electrical receptacle, have the proper
electrical receptacle installed by a qualied 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.

CHECK with a qualied electrician or service personnel if
you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded.

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.
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 1. FIGURE 1
shows a 3-wire electrical plug and electrical receptacle that
has a grounding conductor. If a properly grounded electrcal
receptacle is not available, an adapter as shown in
FIGURE 2 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.

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 a power tool.

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.
