RotoBrute AC42 MAGNETIC DRILL PRESS SAFETY WARNINGS
WARNING Read all safety warnings, instructions, illustrations and specifications provided with
this magnetic drill press. Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury. Save all warnings and instructions for future reference.
For tools equipped with over load protection, when motor has shut down off due to over load, always
run machine with no load for at least 3 minutes to reduce temperature before returning to operation
to avoid burn out of the motor.
1) WORK AREA SAFETY
a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b. Do not operate magnetic drill press 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 magnetic drill press. Distractions can cause
you to lose control.
d. Never leave the electric magnetic drill press unattended. Only leave the machine when the tool in
use has come to a complete standstill.
2) ELECTRICAL SAFETY
a. Magnetic drill press 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 expose power tools to rain or wet conditions. Water entering a magnetic drill press will
increase the risk of electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the magnetic drill
press. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
e. When operating a magnetic drill press outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f. If operating a magnetic drill press in a damp location is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) PERSONAL SAFETY
a. Stay alert, watch what you are doing and use common sense when operating a magnetic drill
press. Do not use a magnetic drill press 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. Always wear eye protection. Protective equipment such as a
dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will
reduce personal injuries.
c. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power
source and/or battery pack, 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.
d. Remove any adjusting key or wrench before turning the magnetic drill press on. A wrench or a key
left attached to a rotating part of the magnetic dr l press may result in personal injury.

e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the
magnetic drill press in unexpected situations.
f. Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
g. If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used. Use of dust collection can reduce dust-related hazards.
h. Do not let familiarity gained from frequent use of tools allow you to become complacent
and ignore tool safety principles. A careless action can cause severe injury within a fraction of a
second.
4) RotoBrute AC42 MAGNETIC DRILL PRESS USE AND CARE
a. Do not force the magnetic drill press. Use the correct magnetic drill press for your application. The
correct magnetic drill press will do the job better and safer at the rate for which it was designed.
b. Do not use the magnetic drill press if the switch does not turn it on and off. Any magnetic drill press
that cannot be controlled with the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source and/or remove the battery pack, if detachable,
from the magnetic drill press before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the magnetic drill press
accidentally.
d. Store idle tool out of the reach of children and do not allow persons unfamiliar with the
magnetic drill press or these instructions to operate the magnetic drill press. Power tools are
dangerous in the hands of untrained users.
e. Maintain magnetic drill press and accessories. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect thetool’s operation. If
damaged, have the magnetic drill press repaired before use. Many accidents are caused by poorly
maintained power tools.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g. Use the magnetic drill press, accessories and tools in accordance with these instructions, taking
into account the working conditions and the work to be performed. Use of the magnetic drill
press for operations different from those intended could result in a hazardous situation.
h. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles
and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
5) SERVICE
Have your magnetic drill press serviced at a qualified Champion Cutting Tool authorized repair center
using only identical replacement parts. This will ensure that the safety of the magnetic drill press is
maintained.

RotoBrute AC42 MAGNETIC DRILL SAFETY WARNINGS
a. The magnetic drill press must be secured. A drill that is not properly secured may move or tip over
and may result in personal injury.
b. The workpiece must be clamped or secured to the workpiece support. Do not drill pieces that are
too small to be clamped securely. Holding the workpiece by hand during operation may result in
personal injury.
c. Do not wear loose gloves. Gloves may be entangled by the rotating parts or chips, leading to personal
injury.
d. Keep your hands out of the drilling area while the tool is running. Contact with rotating parts or
chips may result in personal injury.
e. Make sure the accessory is rotating before feeding into the workpiece. Otherwise the accessory may
become jammed in the workpiece, causing unexpected movement of the workpiece and personal injury.
f. When the accessory is jammed, stop applying downward pressure and switch off the tool.
Investigate and take corrective actions to eliminate the cause of the jam. Jamming can cause
unexpected movement of the workpiece and personal injury.
g. Avoid generating long chips by regularly interrupting downward pressure. Sharp metal chips may
cause entanglement and personal injuries.
h. Never remove chips from the drilling area while the tool is running. To remove chips, move the
accessory away from the workpiece, switch off the tool, and wait for the accessory to stop moving.
Use tools such as a brush or hook to remove chips. Contact with rotating parts or chips may result in
personal injury.
i. Accessories with speed ratings must be rated at least equal to the maximum speed marked on the
magnetic drill press. Accessories running faster than their rated speed can break and fly apart.
MAGNETIC DRILL SPECIFIC SAFETY WARNINGS AND CAUTIONS
a. Always use safety strap. Mounting can release.
b. WARNING: While operating, only hold the crank handles, not any other part of the machine.
Placing the hand on the machine may result in an electric shock in the event of a voltage leak or if the
machine cuts its own power supply cable.
