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.
5) Service
a ) 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.
Additional Safety Rules for Tuckpointing
•
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, it 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 arbor size of wheels, flanges, backing pads or
any other accessory must properly fit the spindle of
the power tool. Accessories with arbor holes that do not
match the mounting hardware of the power tool will run
out of balance, vibrate excessively and may cause loss
of control.
•
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.
•
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.
•
Always use side handle. Tighten the handle securely.
The side handle should always be used to maintain
control of the tool at all times.
Do not use a damaged accessory. Before each use
•
inspect the accessory such as diamond wheel for
chips and cracks, backing pad for cracks, tear or
excess wear, 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.
•
DO NOT grind or cut metal with a diamond wheel.
•
Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and 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 filtrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
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.
•
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 spinning 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 abrasive wheels.
•
ALWAYS use with a dust collector. Dust collector
•
must provide at least 150 cubic feet per minute (cfm) of
airflow and have a filter with 99% or greater efficiency
for respirable particulate and a cyclonic pre-separator or
filter-cleaning mechanism.
•
Operate and maintain tool in accordance with
manufacturer's instructions to minimize dust emissions.
WARNING: When not in use, place grinder
on a stable surface where it will not move
inadvertantly, roll or cause a tripping or falling
hazard. Serious personal injury may result.
Causes and Operator Prevention
of Kickback
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.
