Electrical Safety
1. power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with grounded
power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
2. 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.
3. Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase the risk of electric shock.
4. 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.
5. 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.
6. 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.
personal Safety
1. 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.
2. Use personal protective equipment.
Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
3. prevent unintentional starting.
Ensure the Trigger is in the off-position before connecting to power source, picking up or
carrying the tool.
Carrying power tools with your finger on the Trigger or energizing power tools that have the Trigger on invites accidents.
4. 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.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control of the power tool in unexpected situations.
6. 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.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used. Use of these devices can reduce dust-related hazards.
8. Only use safety equipment that has been
approved by an appropriate standards agency.

power Tool Use and care
1. 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.
2. Do not use the power tool if the Trigger
does not turn it on and off.
Any power tool that cannot be controlled with the
Trigger is dangerous and must be repaired.
3. Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.
4. 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.
5. 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.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. 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.
Service
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.
Router and Trimmer Safety Warnings
1. Hold power tool by insulated gripping surfaces when performing an operation where cutting
tool may contact hidden wiring or its own cord.
Contact with a ″live″ wire will make exposed metal parts of the tool ″live″ and shock the operator.
2. Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
3. Under no circumstance is the Router base ever to be removed from the Router in order to use bits that are too large to use with
the base assembly attached. Removal of the Router base, and using the Router “free hand” can lead to serious bodily injury.
4. If this Plunge Router is to be mounted on a router table, it must be an approved router table and must have all appropriate holding devices and safety shields. Never use a router table which is not specifically designed for use with this Plunge Router.
5. Maintain labels and nameplates on the tool.

Grounding
TO pREVENT ELEcTRIc SHOcK AND DEATH FROM
INcORREcT GROUNDING WIRE cONNEcTION: check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool.
Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged.
If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.
Grounded Tools: Tools with Three prong plugs
3-prong plug and Outlet
1. Tools marked with “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock.
(See 3-prong plug and Outlet.)
2. The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically “live” terminal.
(See 3-prong plug and Outlet.)
3. The tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the preceding illustration.
(See 3-prong plug and Outlet.)
Double Insulated Tools: Tools with Two prong plugs
Outlets for 2-prong plug
1. Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisfies
OSHA requirements and complies with the applicable standards of Underwriters
Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code.
2. Double insulated tools may be used in either of the
120 volt outlets shown in the preceding illustration.
(See Outlets for 2-prong plug.)
Page 6 For technical questions, please call 1-888-866-5797.
Item 37793
Extension cords
1. Grounded tools require a three wire extension cord.
Double Insulated tools can use either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Table A.)
4. When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required. (See Table A.)
5. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use.
Symbology
7. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
8. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.
