SAFETY FIRST
Always wear eye protection while
using cutting tools, or in the vicin-
ity of cutting.
CAUTION! The slug is ejected
at the end of the cut. Do not aim
cutter or arbor so that ejected
slug may hit someone around, or
below you.
CAUTION! Cutters are sharp.
Wear gloves when installing or
removing cutter from arbor. Do
not grab a rotating cutter.
CAUTION! To prevent electric
shock, do not use power tools
near wet areas, or where power
tool may become wet.

Important Safety Instructions
WARNING: Read and understand all instructions. Failure to follow all instructions listed below,
may result in electrical shock, fire and/or serious personal 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 flammable 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 loose control.
Electrical Safety
Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordianaces. Never remove the ground prong or modify the plug in
any way. Do not us any adapter plugs. Check with a qualified
electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break-
down, grounding is provides a low resistance path to carry electricity
away from the user.
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.
Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tools or
pull the plug from an outlet. Keep cord away from heat, oil, sharp
edges or moving parts. Replace damaged cords immediately.
Damaged cords increase the risk of eletric shock.
When operating a power tool outside, use an outdoor extension
cord marked “W-A” or “W”; These cords are rated for outdoor use
and reduce the risk of electrical shock.
Personal Safety
Stay alert, watch what you are doing and use common sense
when using a power tool. Do not use tool while tired or under
the influence of drugs, alcohol, or medication. A moment of inat-
tention 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, j
parts.
Avoid accidental starting. Be sure switchis off before plugging
in. Carrying tools with your finger on the switch or plugging in tools
that have the switch on invites accidents.
ewelry, or long hair can be caught in moving
Use safety equipment. Always wear eye production. Dust
mask, non-skid safety shoes, hard hat, or hearing protection
must be used for appropriate conditions.
Always use safety chain. Mounting can release.
Tool Use and Care
Use clamps or other practical way to secure and support
the work piece 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 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 tool if switch does not turn it on or off. Any
tool that cannot be controlled with the switch is dangerous and
must be repaired.
Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing the
tool. Such preventive safety measures reduce the risk of start-
ing the tool accidentally.
Store idle tools out of reach of childern 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 sharp cutting edges are
less likely to bind and are easier to control.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the
tools operation. If damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools.
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
Tool service must be performed only by qualified repair
personnel. Service or maintenance performed by unqualified
personnel could result in a risk of injury.
When servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section of
this manual. Use of unauthorized parts or failure to follow
Maitenance Instructions may create a risk of electric shock or
injury.
Remove adjusting keys or switches before turning the tool on. A
wrench or a key that is left attached to a rotating part of the 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 tool in unexpected situations.

metal parts of the drill to be made live. Remove chips
wrapped around Cutter and arbor after each hole. With
motor off and power disconnected, grasp chips with
leather gloved hand or pliers and pull while rotating
counterclockwise. Should the cutter become jammed in
the work, stop the unit immediately to prevent personal
injury. Disconnect the drill from the power supply and
loosen jammed cutter by turning the arbor counterclock wise. Never attempt to free the jammed cutter by starting
the motor. Service at authorized repair center only.
Extension Cord Table
Plugs and Receptacles
Operating Near Welding Equipment
DO NOT operate this unit on the same work surface that
welding is being performed on. Severe damage to the
unit, particularly the power cord, could occur. This could
also result in personal injury to the operator.
Circuit Breaker (If Applicable)
Changing of the circuit breaker to a higher amp rated breaker, or
bypassing the circuit breaker is not recommended and will void
product warranty.
Circuit Breaker Operation (If Applicable)
The circuit breaker is a thermal breaker. When it reaches the
higher temperature rating it will trip and cause the unit to shut
down. This is a protective device and can be reset after 5 to 10.
To reset the breaker, press the breaker button back in. If it does
not reset, let the unit cool a little longer until you can push the
button in and it stays in position.
Save these Instructions.
Important Safety Instructions - Continued
WARNING: Read and understand all instructions. Failure to follow all instructions listed below,
may result in electrical shock, fire and/or serious personal injury.
Wet electrical connections are shock hazards. To
prevent the cutting fluid from traveling along the cord
and contacting the plug or power outlet, tie a drip loop
as shown. Also elevate extension cords or gang
box connections.

adjust as needed.
6. Feed Cutter slowly into workpiece. Only after cutting
path is established to a depth of about 1/16" can
additional force be applied to feed handles.
Ease up on feed pressure as cutter starts
breaking through
CAUTION: Do not over-feed cutter. Excessive feed
pressure may cause the magnet to break free from
material.
DRILLING MULTIPLE LAYER MATERIALS:
**Special Cutter Geometry Required!
Second layer penetration may be difficult. Slight
additional feed pressure may be required (avoid overfeed as noted above).
If unable to penetrate second layer, withdraw cutter
from material ejecting slug and clean away any
remaining chips. Feed cutter in hole and continue cut.
• Turn motor off when cut is nished.
• Fully retract cutter from material, ejecting the slug.
• Remove safety strap.
7. Turn magnet switch to "OFF" position.
CAUTION: Retain firm hold on drill to prevent
dropping.
CAUTION:
• Keep strap clear of cutting area, chips, and
rough edges on material.
• Inspect strap periodically for fraying and
damage. Do not use a damaged safety strap.
4. Apply liberal amount of cutting fluid or stick lubricant
to cutter. Additional lubrication may be required to
finish cut.
5. Make certain that cutter is clear of workpiece and
turn motor ON by pressing the motor START button.
Cutter Inside Diameter may collect chips, restricting
depth of cut. Cutter should be frequently inspected
and any chips or debris removed.
