“SAVE THESE INSTRUCTIONS”
General Safety Rules — for all Power Tools
-2-
“READ ALL INSTRUCTIONS” Failure to follow the SAFETY RULES identified by BULLET (•)
symbol listed BELOW and other safety precautions, may result in serious personal injury.
WARNING
!
-3-
• Keep the lower wheel guard attached and working
properly and the guard in the maximum wheel covering
position over the workpiece in operation. Keep your body
positioned to either side of the wheel, but not in line with the
wheel. It is important to position your body and the guard to
minimize body exposure from the possible fragments of a burst
wheel.
• Abrasive Cut Off Wheels must have a maximum safe
operating speed greater than the “no load RPM” marked on
the tool’s nameplate. Wheels running over the rated speed can
fly apart and cause injury.
• Keep hands away from cutting area and wheel. NEVER
place your hand behind the wheel. Do not attempt to
remove cut material when wheel is moving. Contact with the
spinning wheel may cause serious personal injury.
• Wear proper apparel while using an abrasive cut off
machine. Face shield or at least safety goggles, dust mask,
leather gloves and shop apron capable of stopping small wheel
or workpiece fragments.
• Use only Type 1 abrasive cut off wheels with the correct
size arbor hole. Never use damaged or incorrect wheel
flanges or round nut. Other types of wheels are not intended to
apply load on periphery and may shatter. Wheels with arbor
holes that do not match the mounting hardware of the tool will
run eccentrically, vibrate excessively and will cause loss of
control.
• Do not use a cut off wheel that is larger than the maximum
recommended size for your tool, or worn down damaged
wheels from larger abrasive cut off machines. Wheels
intended for larger tools are not suitable for the higher speed of a
smaller tool, these wheels may easily burst and the fragments
strike you or bystanders.
• Before each use inspect the cut off wheel for chips and
cracks. Do not use a wheel that may be damaged. Install a
new wheel if tool was dropped. When installing a new wheel
carefully handle individual cut off wheels to avoid chipping
or cracking. Run the tool at no load for one minute, holding
the tool’s cutting head down and in the direction away from
people. Wheels with flaws will normally break apart during
this time. Fragments from a wheel that bursts during operation
will fly away at great velocity possibly striking you or bystanders.
• Do not grind on the side of Type 1 abrasive cut off wheels.
Side forces applied to these wheels may cause them to shatter.
• Always use the vise to clamp the work and properly
support the over-hanging portion or the workpiece level with
the base of the machine. Proper support of workpiece is
important to keep the cut off and over-hanging pieces from
falling and striking the operator.
• Do not “jam” the abrasive wheel into the work or apply
excessive pressure while using this machine. Avoid
bouncing and snagging the wheel, especially when working
corners, sharp edges etc. If the wheel is damaged due to
misuse it may develop cracks and eventually burst or shatter
without warning.
• Keep the depth stop properly adjusted. If the depth stop is
improperly set it may cause the tool to flip over when releasing
the cutting head too quickly or if the depth is set too deep the
wheel may cut into the surface below the base.
• This machine is not intended to be used with Wet Diamond
Wheels. Using water or other liquid coolants with this machine
may result in electrocution or shock. Use of Dry Diamond
Wheels is acceptable.
• Do not use this tool with “Woodcarving” blade or standard
wood cutting toothed blades. These blades are not intended
for this machine and can create loss of control during use.
• This tool and abrasive wheel are not intended to cut wood
or wood products. Abrasive wheels cut by grinding or fretting
while in work piece with the embedded grit in the wheel, these
grits may grab wood and cause loss of control or could cause
the wood to burn due to friction heating.
• Do not set or mount the tool on a flammable surface or use
the abrasive cut off machine near flammable materials.
During operation the wheel ejects sparks and hot chips from
grinding on the workpiece, these sparks could ignite flammable
materials.
• Never cut or attempt to cut magnesium with this tool. The
dust generated when cutting magnesium is highly flammable
and may be explosive under certain conditions.
• Avoid overloading the motor and prevent burn-out
especially when cutting large cross sectional pieces, apply
light pressure on the handle during cutting. If any sign of
smoke is evident at the air vents, immediately discontinue
the use of the tool. Electric shock is possible if motor is
overloaded and burns out.
• Regularly clean the tool’s air vents by compressed air.
Excessive accumulation of powdered metal inside the motor
housing may cause electrical failures.
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals known to cause
cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry
products, and
• Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that
are specially designed to filter out microscopic particles.

Grounding Instructions For Tools
With Three Prong Plugs
In the event of a malfunction or breakdown, grounding provides
a path of least resistance for electric current to reduce the risk of
electric shock.
Connection To A
Power Source
This machine must be grounded while in use to protect the
operator from electric shock.
Plug power cord into a 110-120V properly grounded type outlet
protected by a 15-amp dual element time delay fuse or circuit
breaker.
Not all outlets are properly grounded. If you are not sure that
your outlet, as pictured below, is properly grounded; have it
checked by a qualified electrician.
To avoid electric shock, do not touch the metal
prongs on the plug when installing or removing
the plug to or from the outlet.
Failure to properly ground this power tool can
cause electrocution or serious shock,
particularly when used near metal plumbing or other metal
objects. If shocked, your reaction could cause your hands to hit
the tool.
If power cord is worn, cut or damaged in any
way, have it replaced immediately to avoid
shock or fire hazard.
Your unit is for use on 120 volts; it has a plug that looks like the
one below.
This power tool is equipped with a 3-conductor cord and
grounding type plug, approved by Underwriters Laboratories
and the Canadian Standards Association. The ground conductor
has a green jacket and is attached to the tool housing at one end
and to the ground prong in the attachment plug at the other end.
This plug requires a mating 3-conductor grounded type outlet as
shown.
If the outlet you are planning to use for this power tool is of the
two-prong type, DO NOT REMOVE OR ALTER THE
GROUNDING PRONG IN ANY MANNER. Use an adapter as
shown and always connect the grounding lug to known ground.
Improper connection of the equipment-grounding conductor can
result in a risk of electric shock. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
It is recommended that you have a qualified electrician replace
the TWO-prong outlet with a properly grounded THREE-prong
outlet.
An adapter as shown below is available for connecting plugs to
2-prong receptacles.
The green grounding lug extending from the
adapter must be connected to a permanent
ground such as a properly grounded outlet box.
NOTE: The adapter illustrated is for use only if you already have
a properly grounded 2-prong receptacle. Adapter is not allowed
in Canada by the Canadian Electrical Code.
The use of any extension cord will cause some loss of power. To
keep this to a minimum and to prevent overheating and motor
burn-out, use the table below to determine the minimum wire
size (A.W.G.) extension cord. Use only 3-wire extension cords
which have 3-prong grounding type plugs and 3-pole
receptacles which accept the tool’s plug.
