WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive atmospheres, such as in the
presence of ammable liquids, gases, or dust. Power tools create sparks which
may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
Use tool in a well ventilated area.
ELECTRICAL SAFETY
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 adapter plugs. Check with a qualied
electrician if you are in doubt as to whether the outlet is properly grounded. If the
Page 2SKU 37793 For technical questions, please call 1-800-444-3353.

tools should electrically malfunction or break down, grounding provides a low resistance
path to carry electricity away from the user.
2.

5.
6.
Double insulated tools are equipped with a polarized plug (one blade is wider than
the other). This plug will t in a polarized outlet only one way. If the plug does
not t fully in the outlet, reverse the plug. If it still does not t, contact a qualied
electrician to install a polarized outlet. Do not change the plug in any way. Double
insulation eliminates the need for the three wire grounded power cord and grounded
power supply system.
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.
Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the Power Cord. Never use the Power Cord to carry the tools or pull
the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or
moving parts. Replace damaged Power Cords immediately. Damaged Power Cords
increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord marked “W-A”
or “W”. These extension cords are rated for outdoor use, and reduce the risk of electric
shock.
PERSONAL SAFETY

4.
5.
6.
Stay alert. Watch what you are doing, and use common sense when operating
a power tool. Do not use a power tool while tired or under the inuence of
drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
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.
Avoid accidental starting. Be sure the Power Switch is off before plugging
in. Carrying power tools with your nger on the Power Switch, or plugging in power
tools with the Power Switch on, invites accidents.
Remove adjusting keys or wrenches before turning the power tool on. A
wrench or a key that is left attached to a rotating part of the power tool may result
in personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE
1.
2.
3.
4.
5.
6.
7.
Use clamps (not included) or other practical ways 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.
Do not force the 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.
Do not use the power tool if the Power Switch does not turn it on or off. Any tool that
cannot be controlled with the Power Switch is dangerous and must be replaced.
Disconnect the Power Cord 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.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools with a sharp cutting edge are less likely to bind and are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until
repaired.
Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
8.
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
1.
2.
Tool service must be performed only by qualied repair personnel. Service or
maintenance performed by unqualied personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instructions
in the “Inspection, Maintenance, And Cleaning” section of this manual. Use of
unauthorized parts or failure to follow maintenance instructions may create a risk of electric
shock or injury.
SPECIFIC SAFETY RULES FOR THE PLUNGE ROUTER
1.
2.
Hold tool by the insulated gripping handles when performing an operation
where the cutting tool may contact hidden wiring or its own cord. Contact with
“live” wire will make exposed metal parts of the tool “live” and shock the operator.
This Router has sharp, fast-moving parts. Misuse can cause severe injury.
Follow the safety instructions.
Page 4SKU 37793 For technical questions, please call 1-800-444-3353.
Page 5
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.

10.
11.
12.
Never touch the bit, collet, or any other moving parts while the Router is in
operation.
Never lay the Router down until it has stopped rotating completely.
Hold the Router firmly when starting, as startup rotation creates significant
torque.
Never hold workpiece by hand. Secure the workpiece by clamping, or with other
holding devices.
Make sure the workpiece is free of nails and other obstacles. These can interfere with
the cutting process, and possibly cause damage and injury.
Hold the tool rmly while cutting. The action of the bit against the workpiece can cause it
to “kick out”, jumping rapidly away from the workpiece. This can be caused by an improper
type, or dull bit being used.
Do not handle the Router bit immediately after cutting. It may be very hot, potentially
causing burns or injury.
Avoid overloading the tool. If the speed drops abnormally, decrease the pressure on the
bit immediately. Do not apply excessive pressure to the router while cutting.
Always use sharpened bits. If the bit stops abruptly, or the bit becomes blocked, remove
the Router from the workpiece and shut it off.
13.
14.
15.
16.
17.
Never start the Router while the bit is in contact with workpiece. Allow the tool to
reach its normal operating speed before applying the bit to the workpiece.
Maintain labels and nameplates on the Router. These carry important information. If
unreadable or missing, contact Harbor Freight Tools for a replacement.
Always wear ANSI-approved safety impact eye glasses, full face shield and
heavy-duty work gloves when using the Router. Using personal safety devices
reduce the risk for injury. Safety impact eye goggles and heavy work gloves are
available from Harbor Freight Tools.
Maintain a safe working environment. Keep the work area well lit. Make sure
there is adequate surrounding workspace. Always keep the work area free of
obstructions, grease, oil, trash, and other debris. Do not use a power tool in areas
near ammable chemicals, dusts, and vapors. Do not use this tool in a damp or
wet locations.
Avoid unintentional starting. Make sure you are prepared to begin work before
turning on the Router.

21.
22.
23.
24.
25.
Always unplug the Router from its electrical outlet before performing any
inspection, maintenance, or cleaning procedures.
Never leave the Router unattended while running. Turn power off if you have
to leave the Router.
Before each use, check all nuts, bolts, and screws for tightness. Vibration
during mixing may cause these to loosen.
Keep extension cord off the ground and away from water.
Always connect the Line Cord (or extension cord) to a Ground Fault Circuit
Interrupter (GFCI) protected electrical outlet.
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 specically designed for use with this
Plunge Router.
People with pacemakers should consult their physician(s) before use. Electromagnetic
fields in close proximity to heart pacemaker could cause pacemaker interference
or pacemaker failure.
26.
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 or 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 filter out microscopic particles. (California Health & Safety
Code § 25249.5, et seq.)
WARNINGWARNING
GROUNDING
Improperly connecting the grounding wire can result in electric
shock.
Check with a qualied 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
Page 6SKU 37793 For technical questions, please call 1-800-444-3353.
Page 7
power cord or plug is damaged. If damaged, have it repaired
by a service facility before use. If the plug will not t the outlet,
have a proper outlet installed by a qualied electrician.
Grounded Tools: Tools with Three Prong Plugs
Note: This product has a line cord with a 3-prong, grounded plug.
1.
2.
3.
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.)
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.)
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 following illustration.
(See 3-Prong Plug and Outlet.)

4.
Extension Cords
Grounded tools require a three wire extension cord. Double Insulated tools can
use either a two or three wire extension cord.
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.)
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.)
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.)
Page 7SKU 37793 For technical questions, please call 1-800-444-3353.
Page 8
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 sufx
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
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 qualied
electrician before using it.
8.
Protect the extension cords from sharp objects, excessive heat, and damp or wet
areas.
