GENERAL SAFETY RULES USA002-2
(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 A re a
1. Keep your work area clean and well lit.
Cluttered benches and dark areas invite accidents.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Powe r
tools create sparks which may ignite the dust
or fumes.
3. Keep bystanders, children, and visitors
away while operating a power tool. Distrac-
tions can cause you to lose control.

Electrical Safety
4. Double insulated tools are equipped with
a polarized plug (one blade is wider than
the other.) This plug will fit in a polarized
outlet only one way. If the plug does not fit
fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insula-
tion eliminates the need for the three wire
grounded power cord and grounded power
supply system.
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.

SERVICE
23. Tool service must be performed only by
qualified repair personnel. Service or main-
tenance 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: 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 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.

SPECIFIC SAFETY RULES USB072-1
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to cutter safety rules. If
you use this tool unsafely or incorrectly, you can suffer serious
personal injury.
1. DANGER! Keep hands away from cutting
area and wheel. Keep your second hand
on auxiliary handle or motor housing. If
both hands are holding the tool, they cannot
be cut by the wheel.
2. Keep your body positioned to either side
of the wheel, but not in line with the wheel.
KICKBACK could cause the tool to jump
backwards. (See “Causes and Operator Prevention of Kickback”)

3. Do not reach underneath the work. Do not
attempt to remove cut material when wheel is
moving.
CAUTION: Wheels coast after turn off.
4. Always observe that the wheel has
stopped spinning before placing tool
down on bench or floor. A coasting wheel
will cause the tool to walk backwards, cutting
whatever is in its path. Be aware of the time it
takes for the wheel to stop after switch is
released.
5. NEVER hold piece being cut in your hands
or across your leg. It is important to support
the work properly to minimize body exposure,
wheel binding, or loss of control.
6. Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord. Contact with a “live” wire will
also make exposed metal parts of the tool
“live” and shock the operator.
7. When ripping always use a rip fence or
straight edge guide. This improves the
accuracy of cut and reduces the chance for
wheel binding.
8. Always use wheels with correct size and
shape (diamond vs. round) arbor holes.
Wheels that do not match the mounting hardware of the tool will run eccentrically, causing
loss of control.
9. Never use damaged or incorrect wheel
washers or bolts. The wheel washers and
bolt were specially designed for your tool, for
optimum performance and safety of operation.
10. Causes and Operator Prevention of Kickback:
Kickback is a sudden reaction to a pinched,
bound, or misaligned wheel, causing an
uncontrolled tool to lift up and out of the workpiece toward the operator.
When the wheel is pinched or bound tightly
by the kerf closing down, the wheel stalls and
the motor reaction drives the unit rapidly back
toward the operator.
If the wheel becomes twisted or misaligned in
the cut, the teeth at the back edge of the
wheel can dig into the top surface of the
material being cut causing the wheel to climb
out of the kerf and jump back toward the
operator.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper precautions as given below:
Maintain a firm grip on the tool and posi-
tion your body and arm to allow you to
resist KICKBACK forces. KICKBACK forces
can be controlled by the operator, if proper
precautions are taken.
When wheel is binding, or when interrupting a cut for any reason, release the trigger and hold the tool motionless in the
material until the wheel comes to a complete stop. Never attempt to remove the
tool from the work or pull the tool backward while the wheel is in motion or KICKBACK may occur. Investigate and take
corrective actions to eliminate the cause of
wheel binding.
When restarting a tool in the workpiece,
center the wheel in the kerf and check that
teeth are not engaged into the material. If
wheel is binding, it may walk up or KICKBACK from the workpiece as the tool is
restarted.
Support large panels to minimize the risk
of wheel pinching and KICKBACK. Large
panels tend to sag under their own weight.
Supports must be placed under the panel on
both sides, near the line of cut and near the
edge of the panel.
To minimize the risk of wheel pinching and
kickback. When cutting operation requires
the resting of the tool on the workpiece, the
tool shall be rested on the larger portion and
the smaller piece cut off.
Do not use dull or damaged wheel.
Unsharpened or improperly set wheels produce narrow kerf causing excessive friction,
wheel binding and KICKBACK.
Wheel depth and bevel adjusting locking
levers must be tight and secure before
making cut. If wheel adjustment shifts while
cutting, it may cause binding and KICKBACK.
Use extra caution when making a “Pocket
Cut” into existing walls or other blind
areas. The protruding wheel may cut objects
that can cause KICKBACK.
NEVER place your hand or fingers behind
the tool. If kickback occurs, the tool could
easily jump backwards over your hand, leading to serious personal injury.
