GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow
all instructions listed below may result in electric shock, re, and/or
serious injury.

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

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

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

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.

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.

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.

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.

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.

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.
