Functional Description - Makita GD0800C Instruction Manual

9. Hold the 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 could give the operator an electric shock.
10. 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.
11. 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.
12. 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.
13. 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.
14. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
15. 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, 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.
a) 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 kickback forces, if proper
precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your hand.
c) Do not position your body in the area where
power tool will move if kickback occurs. Kickback
will propel the tool in direction opposite to the wheel's
movement at the point of snagging.
d) 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.
e) 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:
a) Use only wheel types that are recommended
for your power tool.
b) 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.
c) Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool is
not suitable for the higher speed of a smaller tool and
may burst.
Additional Safety Warnings:
16. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
17. Before using the tool on an actual workpiece, let it
run for a while. Watch for vibration or wobbling
that could indicate poor installation or a poorly
balanced wheel.
18. Use the specified surface of the wheel to perform
the grinding.
19. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
20. Do not leave the tool running. Operate the tool
only when hand-held.
21. Do not touch the workpiece immediately after
operation; it may be extremely hot and could burn
your skin.
22. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
23. Check that the workpiece is properly supported.
24. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.
25. Do not use the tool on any materials containing
asbestos.
26. Always be sure you have a firm footing. Be sure
no one is below when using the tool in high
locations.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to safety
rules for the subject product. MISUSE or failure to
follow the safety rules stated in this instruction
manual may cause serious personal injury.
