 To reduce the risk of injury, read the instruction manual.

General Power Tool Safety Warnings

 

WARNING! Read all safety warnings and all instructions. 

Failure to follow the warnings 

and instructions may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS 

FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.

1) WORK AREA SAFETY

a) 

Keep work area clean and well lit. 

Cluttered or dark areas invite accidents.

b) 

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.

c) 

Keep children and bystanders away while operating a power tool. 

Distractions can 

cause you to lose control.

2) ELECTRICAL SAFETY

a) 

Power tool plugs must match the outlet. Never modify the plug in any way. Do not 
use any adapter plugs with earthed (grounded) power tools. 

Unmodified plugs and 

matching outlets will reduce risk of electric shock.

b) 

Avoid body contact with earthed or grounded surfaces such as pipes, radiators, 
ranges and refrigerators. 

There is an increased risk of electric shock if your body is earthed 

or grounded.

c) 

Do not expose power tools to rain or wet conditions. 

Water entering a power tool will 

increase the risk of electric shock.

d) 

Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the 
power tool. Keep cord away from heat, oil, sharp edges or moving parts. 

Damaged 

or entangled cords increase the risk of electric shock. 

e) 

When operating a power tool outdoors, use an extension cord suitable for outdoor 
use. 

Use of a cord suitable for outdoor use reduces the risk of electric shock. 

f) 

If operating a power tool in a damp location is unavoidable, use a ground fault 
circuit interrupter (GFCI) protected supply.

 Use of a GFCI reduces the risk of electric 

shock.

3) PERSONAL SAFETY

a) 

Stay alert, watch what you are doing and use common sense when operating a 
power tool. Do not use a power tool while you are tired or under the influence of 
drugs, alcohol or medication.

 

A moment of inattention while operating power tools may 

result in serious personal injury.

b) 

Use personal protective equipment. Always wear eye protection. 

Protective 

equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used 
for appropriate conditions will reduce personal injuries.

c) 

Prevent unintentional starting. Ensure the switch is in the off position before 
connecting to power source and/or battery pack, picking up or carrying the tool. 

Carrying power tools with your finger on the switch or energizing power tools that have the 
switch on invites accidents.

d) 

Remove any adjusting key or wrench before turning the power tool on. 

A wrench or 

a key left attached to a rotating part of the power tool may result in personal injury.

e) 

Do not overreach. Keep proper footing and balance at all times. 

This enables better 

control of the power tool in unexpected situations.

f) 

Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and 
gloves away from moving parts. 

Loose clothes, jewelry or long hair can be caught in 

moving parts. 

g) 

If devices are provided for the connection of dust extraction and collection facilities, 
ensure these are connected and properly used. 

Use of dust collection can reduce dust-

related hazards.

4) POWER TOOL USE AND CARE

a) 

Do not force the power tool. Use the correct power tool for your application. 

The 

correct power tool will do the job better and safer at the rate for which it was designed.

b) 

Do not use the power tool if the switch does not turn it on and off. 

Any power tool 

that cannot be controlled with the switch is dangerous and must be repaired.

c) 

Disconnect the plug from the power source and/or the battery pack from the power 
tool before making any adjustments, changing accessories, or storing power tools. 

Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) 

Store idle power tools out of the reach of children and do not allow persons 
unfamiliar with the power tool or these instructions to operate the power tool. 

Power tools are dangerous in the hands of untrained users.

e) 

Maintain power tools. Check for misalignment or binding of moving parts, breakage 
of parts and any other condition that may affect the power tool’s operation. If 
damaged, have the power tool repaired before use. 

Many accidents are caused by 

poorly maintained power tools.

f) 

Keep cutting tools sharp and clean. 

Properly maintained cutting tools with sharp cutting 

edges are less likely to bind and are easier to control.

g) 

Use the power tool, accessories and tool bits, etc. in accordance with these 
instructions, taking into account the working conditions and the work to be 
performed. 

Use of the power tool for operations different from those intended could result 

in a hazardous situation.

5) SERVICE

a) 

Have your power tool serviced by a qualified repair person using only identical 
replacement parts.

 

This will ensure that the safety of the power tool is maintained.

Additional Specifi c Safety Instructions for Cut-Out Tools

• 

Hold power tool by insulated gripping surfaces, because the cutter may contact its 
own cord. 

Cutting a “live” wire may make exposed metal parts of the tool “live” and shock the 

operator.

• 

Use clamps or another practical way to secure and support the workpiece to a stable 
platform.

 Holding the work by your hand or against the body leaves it unstable and may lead 

to loss of control.

• 

Accessories must be rated for at least the speed recommended on the tool warning 
label. 

Wheels and other accessories running over rated speed can fly apart and cause injury. 

Accessory ratings must always be above the tool speed as shown on tool nameplate.

WARNING:

 

After changing bits or making any adjustments, make sure the collet nut is 

securely tightened to avoid injury.

WARNING:

 

Do not press spindle lock or collet lock buttons while motor is running. 

The 

operator may lose control and drop the tool. Personal injury or serious tool damage may result.

WARNING:

 

Shut off all live electric circuits to any areas where cut outs will be made, to 

avoid fire or serious personal injury.

CAUTION:

 

Do not touch the bit or collet nut during or immediately after cutting 

material.

 The bit and collet nut may be hot enough to burn bare skin.

• 

Always wear eye protection.

 Dust mask or hearing protection must be used for appropriate 

conditions. Using personal safety devices is recommended. WORK SAFE.

• 

Always operate the tool with the depth guide in place.

 The guide keeps the bit from 

plunging too deeply through the material. A minimum of penetration should be maintained to 
eliminate the danger of cutting into electric wiring.

• 

Do not use this tool with drill or screwdriver bits.

 This tool is not intended to be used as a 

drill or screwdriver.

• 

Be sure your cutting bits are sharp and in good condition.

 Damaged bits can cause the 

tool to jump, injuring the operator.

• 

Be sure that the motor has stopped completely before you lay the cut-out tool down.

 

If the cutter head is still spinning when the tool is layed down, it could cause injury or damage.

•  Be sure that the cutting bit is clear of the workpiece before starting motor.

 If the bit is in 

contact with the workpiece when the motor starts it could make the tool jump, causing damage 
or injury.

•  If your tool fails to function properly, take it to an authorized service center. 

There 

are no user serviceable parts inside this tool and it should only be opened by trained service 
personnel.

• 

Air vents often cover moving parts and should be avoided.

 Loose clothes, jewelry or long 

hair can be caught in moving parts.

• 

An extension cord must have adequate wire size (AWG or American Wire Gauge) for 
safety. 

The smaller the gauge number of the wire, the greater the capacity of the cable, that is 

16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage 
resulting in loss of power and overheating. When using more than one extension to make up 
the total length, be sure each individual extension contains at least the minimum wire size. The 
following table 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.

Not Recommended

 WARNING:  ALWAYS 

use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use 

face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

•  ANSI Z87.1 eye protection (CAN/CSA Z94.3),
•  ANSI S12.6 (S3.19) hearing protection,
•  NIOSH/OSHA/MSHA respiratory protection.

 WARNING: 

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 and cement and other masonry products, and 

•  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 filter out microscopic particles.
• 

Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and 
other construction activities. Wear protective clothing and wash exposed areas with 
soap and water. 

Allowing dust to get into your mouth, eyes, or lay on the skin may promote 

absorption of harmful chemicals. 

 WARNING: 

Use of this tool can generate and/or disperse dust, which may cause serious and 

permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection 
appropriate for the dust exposure. Direct particles away from face and body.
