⚠WARNING! When using electric tools, basic safety

precautions should always be followed to reduce the
risk of fire, electric shock and personal injury. Read all
these instructions before attempting to operate this
product and save these instructions.

⚠WARNING! CHOKING HAZARD!

Small Parts – Not for children under 3-yrs.

Installation/Assembly

The Drill Doctor ® is completely assembled.

Carefully unpack the power tool and set it on the table. Check to
see that no damage has occurred in shipment. Check all packing
materials to be sure that all parts are present. See “Getting to

know your Drill Doctor

®

” for a parts indentication diagram.

⚠WARNING! Connect to properly wired (115V or 230V, as

applicable) outlet, or electrical shock may occur.

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. Do

not let persons not involved in the work touch the tool or
power cord.

d) Make workshop kid proof with padlocks, master switches

or by removing starter keys.

e) Securely place this tool on your workbench during use.

2. Electrical Safety:

⚠ DANGER! Electrical shock can kill! Read,

understand and follow ALL safety instructions.

⚠ WARNING! Do not expose power tools to rain

or wet conditions. Water entering a power tool will

increase the risk of electric shock.

General Safety Rules

www.drilldoctor.com6

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 abuse the cord. Never use the cord for carrying,

pulling or unplugging the power tool. Never yank the cord
to disconnect it from the socket. Keep cord away from heat,
oil, sharp edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.

d) Use proper extension cord. Use only 3-wire extension

cords that have 3-prong plugs and 3-pole receptacles that
accept the power tool’s plug. Make sure your extension cord
is in good condition. When using an extension cord, be sure
to use one heavy enough to carry the current your product
will draw. Use marked outdoor extension cord leads when
the tool is used outdoors.

e) Disconnect tools. Always disconnect your power tool when

cleaning, inspecting, and changing accessories. When not in
use, disconnect from the power supply. Never touch internal
parts of the sharpener when it is turned on or plugged in.
The rotating diamond wheel can result in injury.

f) Grounding instructions. In the event of a malfunction or

breakdown, grounding provides a path of least resistance for
electric current to reduce risk of electric shock. This power
tool is equipped with an electric cord having an equipment­grounding conductor and grounding plug. Do not modify
the plug provided. The plug must be plugged into a matching
outlet that is properly installed and grounded in accordance
with all codes and ordinances. Improper connection of
the equipment-grounding conductor can result in a risk of
electric shock. The conductor with insulation having an outer
surface that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or replacement
of the electric cord or plug is necessary, do not connect
the equipment-grounding conductor to the live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the tool is properly grounded. Repair
or replace damaged or worn cord immediately.

g) 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.

USA Only

This tool is intended for use on a circuit that has an outlet
that looks like the one illustrated in Fig. A. It has a grounding
plug that looks like the one in Fig. B. A temporary adapter,
which looks like the adapter illustrated in Fig. C & Fig. D, may
be used to connect this plug to a 2-pole receptacle as shown
in Fig. D if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician.
The green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent
ground such as a properly grounded outlet box.

3. Personal Safety:

Sharpening operations can create hot sparks and metal debris,
loud noises and dust.

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 (PPE).

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) Use ear protection during use. Drill Doctor® unit can

generate in excess of 85 dB(A) noise emissions when in
operation.

d) Prevent unintentional starting. Ensure the switch is in

the off-position before connecting to power source and/
or battery pack, and when 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.

www.drilldoctor.com8

e) 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.

f) Do not overreach. Keep proper footing and balance at

all times. This enables better control of the power tool in

unexpected situations. Nonslip footwear is recommended.

g) Dress properly. Wear closed, non-flammable protective

clothing. 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.

h) Secure Work. Use clamps or a vise to hold work when

practical. It’s safer than using your hand and it frees both

hands to operate tool.

4. Power Tool Use and Care

⚠ WARNING! Use recommended accessories. Use the power

tool, accessories, abrasives, 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.

⚠ CAUTION! Keep power tools and work space clean for

best performance and safety. Do not let sharpening debris

accumulate on, in, or around the tool. Accumulated fine metal
sharpening debris can be very hot and may present a fire danger
if the machine or your workspace is not properly cleaned and
maintained. Accumulated sharpening debris can also degrade the
life of the tool and cause premature wear on some components. If
sharpening debris has accumulated, do not immediately throw it
into a trash receptacle without ensuring the debris is completely
cool and free of heat. Improperly disposing of the accumulated
sharpening debris may present a fire risk. Do not collect the
sharpening debris during sharpening. This increases the risk of
heat build-up in the debris and the potential for fire.

a) Do not force the power tool or attachment. Use the

correct power tool for your application. Do not force small
tools to do the job of a heavy duty tool. The correct power
tool will do the job better and safer at the rate for which it is
designed.

b) Use the right tool. Do not force tool or attachment to do a

job for which it is not designed.

c) Do not use the power tool if the switch does not turn it

on or off. Any power tool that cannot be controlled with the

switch is dangerous and must be repaired.

d) Never leave tool running unattended – Turn power off.

Do not leave the tool until it comes to a complete stop.

www.drilldoctor.com 9

e) 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 preventative safety measures reduce the risk of

starting the power tool accidentally.

f) Store idle power tools out of 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.

g) Keep cutting tools sharp and clean for better and safer

performance.

h) Follow instructions for lubricating (if applicable) and for

changing accessories.

i) 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 by an authorized service center
before use. Keep handles dry, clean and free from oil and
grease. Many accidents are caused by poorly maintained
power tools.

j) Inspect tool cord periodically and if damaged have

it repaired by an authorized service center. Inspect

extension cords periodically and repair if damaged.

k) Keep guards in place and in working order. A guard or

other part that is damaged should be properly repaired or
replaced by an authorized service center unless otherwise
indicated in the instruction manual.

l) Never stand on the power tool. Serious injury could

occur if the tool is tipped or if the sharpening edge is
unintentionally contacted.

m) Check damaged parts. Before further use of the tool,

any part that is damaged should be carefully checked to
determine that it will operate properly and perform its
intended function. Check the alignment of moving parts,
binding of moving parts, breakage of parts, mounting and
any other conditions that may affect its operation. Any
damaged part, including the switch, should be properly
repaired or replaced by an authorized service center.

n) Do not use if the grinding wheel is damaged. Use only

grinding wheels recommended by Drill Doctor

Motor

Be sure your power supply agrees with the nameplate marking.
115 Volts means your tool will only operate on standard 60HZ
household power. 230 Volts means your tool will only operate
on standard 50 HZ household power. Do not operate AC tools
on DC. Lower voltage will cause loss of power and can result in
overheating. Using a machine on an unmatched power source
voids your warranty.

Extension Cords

Make sure your extension cord is in good condition. When using
an extension cord, be sure to use on heavy enough to carry the
current voltage resulting in loss of power and overheating. The
Drill Doctor® has a 1.75 ampere rating. 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.
