Mastercraft
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 fingers on the switch or energising power tools that have the switch on invites accidents.
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.
Do not use power tool if the switch does not turn it on and off. 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 battery pack from the power tool before
making any adjustments, changing accessories, or storing power
tool. Such preventative safety measures reduce the risk of starting the tool
accidentally. (17)
Store idle power tools out of the reach of children and do not allow ©
persons unfamiliar with the power tool or these instructions to = 0)
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 of
parts and any other condition that may affect the power tool’s 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. Use of the power
tool for operations different from those intended could result in a hazardous situation.
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 tools is maintained.
SAFETY WARNINGS COMMON FOR GRINDING, ABRASIVE CUTTING-OFF OPERATIONS
This power tool is intended to function as a grinder, or cut-off tool. Read all safety warnings,
instructions, illustrations and specifications provided with this power tool. Failure to
follow all instructions listed below may result in electric shock, fire and/or serious injury.
Operations such as sanding, wire brushing or polishing are not recommended to be per-
formed with this power tool. Operations for which the power tool was not designed may create a
hazard and cause personal injury.
Do not use accessories which are not specifically designed and recommended by the tool
manufacturer. Just because the accessory can be attached to your power tool does not assure
safe operation.
The rated speed of the accessory must be at least equal to the maximum speed marked on
the power tool. Accessories running faster than their RATED SPEED can break and fly apart.
The outside diameter and the thickness of your accessory must be within the capacity
rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
The arbour size of wheels, flanges, backing pads or any other accessory must properly fit
the spindle of the power tool. Accessories with arbour holes that do not match the mounting hard
ware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
Do not use a damaged accessory. Before each use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for cracks, tear or excess wear, or wire brush for
loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install
an undamaged accessory. After inspecting and installing an accessory, position yourself
and bystanders away from the plane of the rotating accessory and run the power tool at
maximum no-load speed for one minute. Damaged accessories will normally break apart during
this test time.
Wear personal protective equipment. Depending on application, use a face shield, safety
goggles or safety glasses. As appropriate, wear a dust mask, hearing protectors, gloves
and a workshop apron capable of stopping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris generated by various operations. The dust mask
or respirator must be capable of filtering particles generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.

Mastercraft
Keep bystanders a safe distance away from work area. Anyone entering the work area
must wear personal protective equipment. Fragments of workpiece or of a broken accessory may
fly away and cause injury beyond immediate area of operation.
Hold power tool by insulated gripping surfaces only, when performing an operation where
the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting
a “live” wire may make exposed metal parts of the power tool “live” and shock the operator.
Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into the spinning accessory.
Never lay the power tool down until the accessory has come to a complete stop. The spin-
ning accessory may grab the surface and pull the power tool out of your control.
Do not run the power tool while carrying it at your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the accessory into your body.
Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal may cause electrical hazards.
Do not operate the power tool near flammable materials. Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Using water or other liquid coolants may
result in electrocution or shock.
Do not use Type 11 (flaring cup) wheels on this tool. Using inappropriate accessories can result in injury.
Always use side handle. Tighten the handle securely. The side handle should always be used to
maintain control of the tool at all times.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other
accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the
binding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that
is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out.
The wheel may either jump toward or away from the operator, depending on direction of the wheel's movement at
the point of pinching. Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
Maintain a firm grip on the power tool and position your body and arm to allow you to
resist Kickback forces. Always use auxiliary handle, if provided, for maximum control over
kickback or torque reaction during start-up. The operator can control torque reactions or Kick-
back forces, if proper precautions are taken.
Never place your hand near the rotating accessory. Kickback may propel the accessory over your hand.
Do not position your body in the area where power tool will move if kickback occurs. Kick-
back will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and
cause loss of control or kickback.
Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create
frequent kickback and loss of control.
SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE GUTTING-OFF OPERATIONS
Use only wheel types that are recommended for your power tool and the specific guard
designed for the selected wheel. Wheels for which the power tool was not designed cannot be
adequately guarded and are unsafe.
The guard must be securely attached to the power tool and positioned for maximum safety,
so the least amount of wheel is exposed towards the operator. The guard helps to protect
operator from broken wheel fragments and accidental contact with wheel.
Wheels must be used only for recommended applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
Always use undamaged wheel flanges that are of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from grinding wheel flanges.
Do not use worn down wheels from larger power tools. Wheels intended for larger power tools are
not suitable for the higher speed of a smaller tool and may burst.
ADDITIONAL SAFETY WARNINGS SPECIFIC FOR ABRASIVE CUTTING-OFF OPERATIONS
Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting
or binding of the wheel in the cut and the possibility of kickback or wheel breakage.
Do not position your body in line with and behind the rotating wheel. When the wheel, at the
point of operation, is moving away from your body, the possible kickback may propel the spinning
wheel and the power tool directly at you.
When wheel is binding, or when interrupting a cut for any reason, switch off the power
tool and hold the power tool motionless until the wheel comes to a complete stop. Never

Mastercraft
attempt to remove the cut-off wheel from the cut while the wheel is in motion or
kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding.
Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in
the workpiece.
Support panels or any oversized workpiece to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the
workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.
Use extra caution when making a “pocket cut” into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
ADDITIONAL SAFETY INFORMATION
Do not use flat abrasive or diamond wheels without the proper cutting wheel guard.
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of
harmful chemicals.
WARNING!
ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust
mask if operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
e ANSI Z87.1 eye protection (CAN/CSA 794.3).
* ANSI $12.6 (S3.19) hearing protection.
e NIOSH/OSHA/MSHA respiratory protection.
LU LH
Use of this tool can generate and/or disperse dust, which may cause serious and permanent
respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate
for the dust exposure. Direct particles away from face and body.
WARNING!
Always wear proper personal hearing protection that conforms to ANSI S12.6 (53.19) during use.
Under some conditions and duration of use, noise from this product may contribute to hearing
loss.
WARNING!
Always use eye protection. All users and bystanders must wear eye protection that conforms to
ANSI Z87.1.
WARNING!
When not in use, place grinder on a stable surface where it will not move inadvertently, roll or
cause a tripping or falling hazard.
DOUBLE INSULATION
e Double insulation is a concept in safety in electric power tools, which eliminates the need for the
usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal
motor components with protecting insulation. Double-insulated tools do not need to be grounded.
ELECTRICAL CONNECTION
e This tool has a precision-built electric motor. It should be connected to a power supply that is
120 volts, AC only (normal household current), 60 Hz. Do not operate this tool on direct
current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If
the tool does not operate when plugged into an outlet, double-check the power supply.
EXTENSION CORDS
e When using a power tool at a considerable distance from a power source, be sure to use an
extension cord that has the capacity to handle the current the tool will draw. An undersized cord will
cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine
the minimum wire size required in an extension cord. Only round-jacketed cords listed by Under
writers Laboratories (UL) should be used.
NOTE:
Servicing of a tool with double insulation requires extreme care and knowledge of the system and should be
performed only by a qualified service technician. For service, we suggest you return the tool to your nearest
authorized service centre for repair. Always use original factory replacement parts when servicing.
CAUTION!
To reduce the risk of personal injury, use extra care when working into a corner or edge
because a sudden, sharp movement of the tool may be experienced when the wheel or other
accessory contacts a secondary surface or a surface edge.
WARNING!
e The double-insulated system is intended to protect the user from shock resulting from a
break in the tool’s internal insulation. Observe all normal safety precautions to avoid electrical
shock.

e Move the grinder continuously at a steady, consistent pace.
e Use just enough pressure to keep the grinder from chattering or bouncing.
e Lift the grinder away from the workpiece before turning off the grinder.
USING CUTTING WHEELS
e Allow tool to reach full speed before touching tool to work surface.
o Apply minimum pressure to work surface, allowing tool to operate at high speed. Cutting rate
is greatest when the tool operates at high speed.
GRINDING WITH GRINDING WHEELS (Fig. 11)
Always carefully select and use grinding wheels that are
recommended for the material to be ground. Make sure
that the operating speed of any accessory wheel se-
lected is rated at 11,000 RPM or more.Pay attention to
the dimensions of the grinding tools. The mounting hole
diameter must fit the mounting flange without play. Do not
use reducers or adapters.
e Once a cut is begun and a notch is established in the workpiece, do not change the angle of the cut.
Changing the angle will cause the wheel to bend and may cause wheel breakage.
* Remove the tool from work surface before turning tool off. Allow the tool to stop ratating before
setting it down.
OPERATING INSTRUCTIONS
OPERATING INSTRUCTIONS
e Secure all work in a vise or clamp to a workbench.
e Hold the grinder in front and away from you with
both hands, keeping the grinding wheel clear of the
workpiece.
e Turn on the grinder and let the motor and grinding
wheel build up to full speed.
NOTE:
If the grinder is held in one spot too long, it will gouge and cut grooves in the workpiece. If the grinder is held
at too sharp an angle, it will also gouge the workpiece because of concentration of pressure on a small area.
LUE TH
To prevent loss of control and possible serious personal injury, always operate the grinder with
both hands, keeping one hand on the side handle. NOTE:
Heavy pressure will decrease the grinder’s speed and put a strain on the motor. Normally the weight of the
tool alone is adequate for most grinding jobs. Use light pressure when grinding jagged edges or loose bolts
where there is the potential for the grinder to snag on the metal edge.
DANGER!
Never use the grinder with the wheel guard removed and always be sure the wheel guard is
locked into place. It has been designed for use only with the wheel guard installed. Attempting
to use grinder with wheel guard removed will result in loose particles being thrown against the
operator resulting in serious personal injury.
WARNING!
Cutting wheel guard must be used while using cutting wheels.
