This instruction manual includes the following: General Safety Rules / Specific
Safety Rules and Symbols Functional / Description / Assembly / Operation
Maintenance / Accessories
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 during
the operation of a power tool.
Use hearing protection, particularly during extended periods of
operation of the tool, or if the operation is noisy.

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.
Any power
tool 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,
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. 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
performed.
could result in a hazardous situation.
Hold power tools by insulated gripping surfaces when performing an operation
where 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.
