Before using this tool or any of its accessories, read this manual and follow all Safety
Rules and Operating Instructions. The important precautions, safeguards and
instructions appearing in this manual are not meant to cover all possible situations.
It must be understood that common sense and caution are factors which cannot be
built into the product.
EYE, EAR & LUNG PROTECTION
SYMBOL MEANING
ALWAYS WEAR EYE PROTECTION THAT CONFORMS
WITH CSA Z94.3 or ANSI SAFETY STANDARD Z87.1
FLYING DEBRIS can cause permanent eye damage.
Prescription eyeglasses ARE NOT a replacement for proper eye protection.
Non-compliant eyewear can cause serious injury if broken

POWER TOOL SAFETY
WARNING:
Read all safety warnings and instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE.
WORK AREA SAFETY
Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
ELECTRICAL SAFETY
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.
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.
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 cord. Never use 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 outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of a ground fault circuit interrupter (GFCI)
reduces 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 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.
Use personal protective equipment. 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.
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.

5
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.
Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewellery or long hair can be caught
in moving parts.
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.
POWER TOOL USE AND CARE
Do not force the power tool. Use 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.
that cannot be controlled with the switch is dangerous and must be repaired.
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 preventive safety measures reduce the risk of starting the power tool
accidentally.
Store idle power tools out of the 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 misalignment or binding of moving parts, breakage
damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
result in a hazardous situation.
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.
SERVICE
Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.

SPECIFIC SAFETY RULES
WARNING:
Know your rotary tool. Do not plug the tool into the power source until you have
read and understand this Instruction Manual. Learn the tool’s applications and
limitations, as well as the specific potential hazards related to this tool. Following
this rule will reduce the risk of electric shock, fire, or serious injury.
Always wear eye protection. Any power tool can throw foreign objects
into your eyes and cause permanent eye damage.
ALWAYS wear safety goggles (not glasses) that comply with ANSI safety standard
Z87.1. Everyday glasses have only impact resistant lenses. They ARE NOT safety
glasses.
WARNING: Glasses or goggles not in compliance with ANSI Z87.1 could
cause serious injury when they break.
Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live” and shock the operator.
Always make sure the work surface is free from nails and other foreign objects.
Cutting into a nail can cause the bit and the tool to jump and damage the bit.
Never hold the workpiece in one hand and the tool in the other hand when in use.
Never place the hands near or below the cutting surface. Clamping the material and
guiding the tool with both hands is much safer.
Never lay workpiece on hard surfaces like concrete, stone, etc. Protruding cutting
bit may cause the tool to jump.
Always wear safety goggles and dust mask. Use only in well-ventilated area. Using
personal safety devices and working in a safe environment reduces risk of injury.
After changing the bits and accessories or making adjustments, make sure
the collet nut and any other adjustment devices are securely tightened. Loose
adjustment devices will be violently thrown.
Always use the correct collet size. If the collet size is larger than the accessory
shank size it will not grip the shank properly, leading to possible injury to the
operator or damage to the tool.
each use. Damaged accessories can break during use and cause serious injury.
Never use dull or damaged bits. Sharp bits must be handled with care. Damaged
bits can snap during use. Dull bits require more force to push the tool, possibly
causing the bit to break.
Never touch the bit during or immediately after use. After use the bit is too hot to be
touched by bare hands.

EXTENSION CORD SAFETY
WARNING:
Keep the extension cord clear of the working area. Position the cord so it will not get
caught on the workpiece, tools or any other obstructions while you are working with
the power tool.
Make sure any extension cord used with this tool is in good condition. When using
an extension cord, be sure to use one of heavy enough gauge to carry the current
the tool will draw. An undersized cord will cause a drop in line voltage resulting in
loss of power and overheating.
The table at below shows the correct size to use according to cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the
gauge number the heavier the cord.
Be sure your extension cord is properly wired and in good condition. Always replace
a damaged extension cord or have it repaired by a qualified electrician before using
it. Protect your extension cord from sharp objects, excessive heat and damp or wet
areas.
Use a separate electrical circuit for your power tools. This circuit must not be less
than 14 gauge wire and should be protected with either a 15 AMP time delayed fuse
or circuit breaker. Before connecting the power tool to the power source, make sure
the switch is in the OFF position and the power source is the same as indicated on
the nameplate. Running at lower voltage will damage the motor.
