GENERAL SAFETY RULES
USA001-3
(For All Tools)
WARNING:
Read and understand all instructions. Failure to follow all
instructions listed below, may result in electric shock, fire and/or
serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
Electrical Safety
1. Keep your work area clean and well lit.
Cluttered benches and dark areas invite accidents.
4. Grounded tools 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 adaptor plugs. Check with a
qualified electrician if you are in doubt as
to whether the outlet is properly
grounded. If the tools should electrically malfunction or break down, grounding provides a
low resistance path to carry electricity away
from the user.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the dust
or fumes.
3. Keep bystanders, children, and visitors
away while operating a power tool. Distractions can cause you to lose control.
2
5. 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.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. Do not abuse the cord. Never use the cord
to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace
damaged cords immediately. Damaged
cords increase the risk of electric shock.
8. When operating a power tool outside, use
an outdoor extension cord marked “W-A”
or “W”. These cords are rated for outdoor
use and reduce the risk of electric shock.
Personal Safety
9. Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
10. 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.
11. Avoid accidental starting. Be sure switch
is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools
that have the switch on invites accidents.
12. Remove adjusting keys or wrenches
before turning the tool on. A wrench or a
key that is left attached to a rotating part of
the tool may result in personal injury.
13. Do not overreach. Keep proper footing
and balance at all times. Proper footing and
balance enables better control of the tool in
unexpected situations.
14. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions. Ordinary
eye or sun glasses are NOT eye protection.
Tool Use and Care
15. Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or
against your body is unstable and may lead
to loss of control.
16. Do not force tool. Use the correct tool for
your application. The correct tool will do the
job better and safer at the rate for which it is
designed.
17. Do not use tool if switch does not turn it
on or off. Any tool that cannot be controlled
with the switch is dangerous and must be
repaired.
18. Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
19. Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
20. Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools with sharp cutting edges are less likely
to bind and are easier to control.
21. Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool serviced before using. Many accidents are
caused by poorly maintained tools.
22. 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.
3
SERVICE
23. Tool service must be performed only by
qualified repair personnel. Service or maintenance performed by unqualified personnel
could result in a risk of injury.
24. When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.
USE PROPER EXTENSION CORD: Use only three-wire extension cords that have
three-prong grounding-type plugs and three-pole receptacles that accept the tool's
plug. Make sure your extension cord is in good condition. Replace or repair damaged
or worn cord immediately. 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 overheating. Table 1 shows the
correct size to use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
