Item 56790
i.
Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As
appropriate, wear dust mask, hearing
protectors, gloves and shop 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.
j.
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 wheel may fly away and cause injury
beyond immediate area of operation.
k.
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 wheel.
l.
Regularly clean the power tool’s air vents.
The motor’s fan can draw the dust inside
the housing and excessive accumulation of
powdered metal may cause electrical hazards.
m.
Do not operate the power tool near flammable
materials. Do not operate the power tool
while placed on a combustible surface such
as wood.
Sparks could ignite these materials.
n.
Do not use accessories that require liquid
coolants.
Using water or other liquid coolants
may result in electrocution or shock.

Kickback and related warnings
- Kickback is a sudden reaction to a pinched or
snagged rotating wheel. Pinching or snagging
causes rapid stalling of the rotating wheel which
in turn causes the uncontrolled cutting unit to
be forced upwards toward the operator.
- 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. 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.
a.
Maintain a firm grip on the power tool
and position your body and arm to
allow you to resist kickback forces.
The
operator can control upward kickback
forces, if proper precautions are taken.
b.
Do not position your body in line with the
rotating wheel.
If kickback occurs, it will propel
the cutting unit upwards toward the operator.
c.
Do not attach a saw chain, woodcarving
blade, segmented diamond wheel with
a peripheral gap greater than 10 mm or
toothed saw blade.
Such blades create
frequent kickback and loss of control.
d.
Do not “jam” the 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.
e.
When the wheel is binding or when
interrupting a cut for any reason, switch
off the power tool and hold the cutting unit
motionless in the material until the wheel
comes to a complete stop. Never attempt
to remove the wheel from the cut while
the wheel is in motion or kickback may
occur.
Investigate and take corrective actions
to eliminate the cause of wheel binding.
f.
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully re-enter the cut.
The wheel
may bind, walk up or kickback if the power
tool is restarted in the workpiece.
g.
Support any oversized workpiece to minimise
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.
Vibration Safety
This tool vibrates during use. Repeated or long-term
exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and
shoulders. To reduce the risk of vibration-related injury:
a. Anyone using vibrating tools regularly or for
an extended period should first be examined
by a doctor and then have regular medical
check-ups to ensure medical problems are not
being caused or worsened from use. Pregnant
women or people who have impaired blood
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or Raynaud’s
Disease should not use this tool. If you feel
any symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
b. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
c. Wear suitable gloves to reduce the
vibration effects on the user.
d. Use tools with the lowest vibration when there
is a choice between different processes.
e. Include vibration-free periods each day of work.
