Operation; Maintenance - Black & Decker KG8200 Operating Instructions Manual

ENGLISH
• Check mounting flanges and the disc are correctly fitted
and are undamaged.
• Ensure you are using the correct size and type of disc
for the task.
• Ensure the disc, wire brush and sanding accessories are
rated in excess of the spindle rpm of your angle grinder.
Allow a newly assembled wheel to idle off- load for 30
seconds before starting any operation.

Operation

Operating your angle grinder (Fig. A)
To switch on, push the slider switch forward (1). To switch
off, press the rear of the slider switch.
Fittingthe discs (Fig. B and C)
Proceed as follows:
• Disconnect the plug from the electricity supply.
• Ensure the guard is fitted. Place the inner flange (7) on
the spindle. Ensure it is located on the two flats.
• Place the abrasive disc on the spindle and inner flange
(8). Ensure it is correctly located.
• Fit the threaded outer flange (9), making sure it is facing
in the correct direction for the type of disc fitted. For
grinding discs, the flange (9) is fitted with the raised
portion facing towards the disc. For cutting discs, the
flange (9) is fitted with the inner portion facing away from
the disc.
• Hold the spanner on the flats of the spindle to prevent
rotation of the disc and tighten the outer flange with the
spanner provided.
• Press in the spindle lock button and rotate the spindle
until it locks (Fig. C). Keeping the lock button pressed in,
tighten the outer flange with the spanner provided.
Fitting sanding discs (fig. D)
• Use a sanding disc with the backing pad for sanding with
your angle grinder.
• Disconnect the plug from the electricity supply.
6
• Remove the guard.
• Place the flange on the spindle. Place the backing pad on
the spindle and inner flange, ensuring it is correctly
located.
• Mount the fibre backed abrasive disc on the backing pad.
• Fit the threaded outer flange and tighten as explained in
'Fitting the discs'.
Handy hints (Fig. E)
Hold your angle grinder firmly with one hand around the side
handle and the other around the body of your angle grinder.
• Always position the guard so that as much of the
exposed disc as possible is pointing away from you.
• Be prepared for a stream of sparks when the disc
touches the metal.
When grinding, always maintain the correct angle between
the disc and the work surface (15°)(Fig. D). This increases
the removal capacity of the disc and avoids unnecessary
overloading.
Overload
Overloading will cause damage to the motor of your angle
grinder. This can happen if your angle grinder is subjected to
heavy duty use for prolonged periods of use. Do not in any
circumstances, attempt to exert too much pressure on your
angle grinder to speed up your work. The abrasive discs
operate more efficiently when a light pressure is exerted, thus
avoiding a drop in the speed of your angle grinder.

Maintenance

Keep guards, air vents and the motor housing as clear as
possible of dust and dirt. Wipe with a clean cloth and blow
through with a low-pressure air supply. Excessive build-up of
metal dust can cause tracking of electrical current from the
internal parts to exposed metal parts. Do not overload your
angle grinder. Overloading causes a reduction in speed and
efficiency, causing your angle grinder to become too hot. If
this happens, operate your angle grinder under no load for
one or two minutes until it has cooled to normal operating
temperature. Switching your angle grinder off under load will
reduce the life of the switch.
