General Safety Rules
WARNING! Read all instructions
Failure to follow all instructions
listed below may result in
electric shock, re, and/or
serious injury. The term “power
tool” in all of the warnings listed
below refers to your Duel Dowel
Jointer.
SAVE THESE INSTRUCTIONS
Work area safety1.
Keep work area clean and well a.
lit. Cluttered or dark areas invite
accidents.
Do not operate power tools in b.
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 children and bystanders c.
away while operating a power tool.
Distractions can cause you to lose
control.
Electrical safety2.
Power tool plugs must match the a.
outlet. Never modify the plug in
any way. Do not use any adapter
plugs with grounded power tools.
Unmodied plugs and matching

outlets will reduce risk of electric
shock.
Avoid body contact with grounded b.
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 c.
or wet conditions. Water entering a
power tool will increase the risk of
electric shock.
Do not abuse the cord. Never use d.
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.
When operating a power tool e.
outdoors, use an extension cord
suitable for outdoor use. Use of
a cord suitable for outdoor use
reduces the risk of electric shock.
Personal safety3.
Stay alert, watch what you are a.
doing and use common sense
when operating a power tool. Do
not use a power tool while you are
tired or under the inuence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
Use safety equipment. Always wear b.
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.
Avoid accidental starting. Ensure c.
the switch is in the off-position
before plugging in. Carrying power
tools with your nger on the switch
or plugging in power tools that have
the switch on invites accidents.
Remove any adjusting key or wrench d.
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.
Do not overreach. Keep proper e.
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
Dress properly. Do not wear loose f.
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.
If devices are provided for the g.
connection of dust extraction and
collection facilities, ensure these are
connected and properly used. Use
of these devices can reduce dustrelated hazards.
Power tool use and care4.
Do not force the power tool. Use a.
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.
Do not use the power tool if the b.
switch does not turn it on and
off. Any power tool that cannot
be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the power c.
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
Page 3SKU 97427 For technical questions, please call 1-800-444-3353.
the risk of starting the power tool
accidentally.
Store idle power tools out of the d.
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.
Maintain power tools. Check for e.
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.
Keep cutting tools sharp and clean. f.
Properly maintained cutting tools
with sharp cutting edges are less
likely to bind and are easier to
control.
Use the power tool, accessories and g.
tool bits etc., in accordance with
these instructions and in the manner
intended for the particular type of
power tool, 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.
Service5.
Have your power tool serviced by a.
a qualied repair person using only
identical replacement parts. This will
ensure that the safety of the power
tool is maintained.
Vibration Hazard
This tool vibrates during use.
Repeated or long-term exposure to
vibration may cause temporary or
permanent physical injury, particularly
to the hands, arms and shoulders. To
reduce the risk of vibration-related
injury:
Anyone using vibrating tools regularly 1.
or for an extended period should
rst be examined by a doctor and
then have regular medical checkups to ensure medical problems are
not being caused or worsened from
use. Pregnant women or people
who have impaired blood circulation
to the hand, past hand injuries,
nervous system disorders, diabetes,
or Raynaud’s Disease should not
use this tool. If you feel any medical
or physical symptoms related to
vibration (such as tingling, numbness,
and white or blue ngers), seek
medical advice as soon as possible.
Do not smoke during use. Nicotine 2.
reduces the blood supply to the
hands and ngers, increasing the risk
of vibration-related injury.
Wear suitable gloves to reduce the 3.
vibration effects on the user.
Use tools with the lowest vibration 4.
when there is a choice between
different processes.
Include vibration-free periods each 5.
day of work.
Grip tool as lightly as possible (while 6.
still keeping safe control of it). Let
the tool do the work.
To reduce vibration, maintain the tool 7.
as explained in this manual. If any
abnormal vibration occurs, stop use
immediately.

Specic Safety Rules
Maintain labels and nameplates on 1.
the tool. These carry important safety
information. If unreadable or missing,
contact Harbor Freight Tools for a
replacement.
Always examine the workpiece for 2.
foreign objects. Never attempt to cut
into nails or other metal objects.
Always keep your hands and ngers 3.
well away from the chip ejection area
while the tool is running.
Avoid unintentional starting. Prepare 4.
to begin work before turning on the
tool.
Begin cutting only when the Bits have 5.
reached full speed.
Keep the Cutter Head and Drive 6.
Guards in place and in proper
working order.
Do not make jointing or planing cuts 7.
deeper than 1/8 inch.
Use clamps (not included) or other 12.
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.
This product is not a toy. Keep it out 13.
of reach of children.
People with pacemakers should 14.
consult their physician(s) before
use. Electromagnetic elds in close
proximity to heart pacemaker could
cause pacemaker interference or
pacemaker failure. In addition,
people with pacemakers should:
• Avoid operating alone.
• Do not use with power switch locked
on.
• Properly maintain and inspect to
avoid electrical shock.
• Any power cord must be properly
grounded. Ground Fault Circuit
Interrupter (GFCI) should also be
implemented – it prevents sustained
electrical shock.
Use hold-down/push blocks for 8.
jointing material narrower than 3
inches, or planing material thinner
than 3 inches.
Do not perform jointing or planing 9.
cuts on pieces shorter than 8 inches
in length.
Do not lay the tool down until it has 10.
come to a complete stop. Moving
parts can grab the surface and pull
the tool out of your control.
Do not leave the tool unattended 11.
when it is plugged into an electrical
outlet. Turn off the tool, and unplug
it from its electrical outlet before
leaving.
Some dust created by power 15.
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
