Power tool use and care
a) 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.
b) Do not use the 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.
c) Disconnect the plug from the power source
and/or remove the battery pack, if detachable,
from the power tool before making any
adjustments, changing accessories, or storing
power tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools and accessories with
care. 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.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) 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.
h) Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow safe
handling and control of the tool in unexpected
situations.
2.5
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.
3. Special Safety Instructions
a) Do not use accessories that are not
specifically designed and recommended for
this power tool by the manufacturer. Just
because the accessory can be attached to your
power tool, it does not assure safe operation.
b) Do not use damaged power tools. Before
use, check the indexable inserts for chipping,
cracks or signs of severe wear and tear. If a
power tool or accessory is dropped, inspect for
damage or install an undamaged accessory.
c) Wear personal protective equipment. Use a
face shield, safety goggles or safety goggles
6
depending on the application. 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. A dust mask or
respirator must be capable of filtering particles
generated by your operation. Prolonged exposure
to high intensity noise may cause hearing loss.
d) Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Fragments
of a workpiece or broken accessory may fly away
and cause injury beyond the immediate area of
operation.
e) Always hold the tool firmly in your hands
during the start-up. The reaction torque of the
motor as it accelerates to full speed can cause the
tool to twist.
f) Use clamps to support the workpiece
whenever practical. Never hold a small
workpiece in one hand and the tool in the other
hand while in use. Clamping a small workpiece
allows you to use your hands to control the tool.
g) Never lay the power tool down until the
accessory has come to a complete stop. The
rotating accessory may grab the surface and pull
the power tool out of your control.
h) Do not run the power tool while carrying it at
your side. Accidental contact with the rotating
accessory could snag your clothing, pulling the
accessory into your body.
i) 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.
j) Do not operate the power tool near flammable
materials. Sparks and hot chips can ignite these
materials.
k) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
3.1
Kickback and related warnings
Kickback is the sudden response to an accessory
pinching or jamming while rotating. Pinching or
snagging causes rapid stalling of the rotating
accessory. This 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 indexable insert is snagged or
pinched by the workpiece, the edge of the insert that
is entering into the pinch point can dig into the
surface of the material causing the insert to climb
out or kick out. The indexable insert may either jump
towards or away from the operator depending on
direction of the indexable insert holder at the point
of pinching. Indexable inserts 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.
