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
starting the tool accidentally.
Store idle tools out of reach of children 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. Any alteration or
modification is a misuse and may result in a
dangerous condition.
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
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. If cutting into
existing walls or other blind areas where
electrical wiring may exist is unavoidable,
disconnect all fuses or circuit breakers
feeding this worksite.
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 hands near or below cutting
surface. Clamping the material and guiding
the tool with both hands is safer.
Never lay workpiece on top of hard
surfaces, like concrete, stone, etc...
Protruding cutting bit may cause tool to
jump.

serviced before using. Many accidents are
caused by poorly maintained tools. Develop a
periodic maintenance schedule for your tool.
Use only accessories that are recom-
mended by the manufacturer for your
model. Accessories that may be suitable for
one tool, may become hazardous when used
on another tool.
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced or
pinched, safety guard return springs may be
improperly mounted.
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
Maintenance Instructions may create a risk of
electric shock or injury. Certain cleaning
agents such as gasoline, carbon tetrachloride,
ammonia, etc. may damage plastic parts.
Rotary Cutter Safety Rules
Always wear safety goggles and dust
mask. Use only in well ventilated area.
Using personal safety devices and working
in safe environment reduces risk of injury.
After changing the bits or making any
adjustments, make sure the collet nut and
any other adjustment devices are
securely tightened. Loose adjustment
device can unexpectedly shift, causing loss
of control, loose rotating components will be
violently thrown.
Never start the tool when the bit is
engaged in the material. The bit cutting
edge may grab the material causing loss of
control of the cutter.
Always hold the tool with two hands
during start-up. The reaction torque of the
motor can cause the tool to twist.
The direction of feeding the bit into the
material is very important and it relates to
the direction of bit rotation.
viewing the tool from the top, the bit
rotates clockwise. Feed direction of
