Maintenance And Cleaning - Defort BWS-910-P Bedienungsanleitung

• 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.
• Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kick-
back and loss of control.
Safety warnings specific for Grinding
and Abrasive Cutting-Off operations
• Use only wheel types that are recommended for your
power tool and the specific guard designed for the se-
lected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
• The grinding surface of the centre depressed wheels
must be mounted below the plane of the guard lip. An
improperly mounted wheel that projects through the
plane of the guard lip cannot be adequately protected.
• 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,
accidental contact with wheel and sparks that could
ignite clothing.
• Wheels must be used only for recommended applica-
tions. For example: do not grind with the side of the
cut-off wheel. Abrasive cut-off wheels are intended for
peripheral grinding; side forces applied to these wheels
may cause them to shatter.
• Always use undamaged wheel flanges that are of correct
size and shape for your selected wheel. Proper wheel
flanges support the wheel thus reducing the possibility
of wheel breakage. Flanges for cut-off wheels may be
different from grinding wheel flanges.
• Do not use worn down reinforced wheels from larger
power tools. Wheels intended for larger power tools are
not suitable for the higher speed of a smaller tool and
may burst.
Additional safety warnings specific for abrasive
cutting off operations
• Do not "jam" the cut-off wheel or apply excessive pres-
sure. Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and sus-
ceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
• Do not position your body in line with and behind the
rotating wheel. When the wheel, at the point of opera-
tion, is moving away from your body, the possible kick-
back may propel the spinning wheel and the power tool
directly at you.
• When wheel is binding or when interrupting a cut for
any reason, switch off the power tool and hold the pow-
er tool motionless until the wheel comes to a complete
stop. Never attempt to remove the cut-off wheel from
the cut while the wheel is in motion otherwise kickback
may occur. Investigate and take corrective action to
eliminate the cause of wheel binding.
• 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.
• Support panels or any oversized workpiece to minimize
the risk of wheel pinching and kickback. Large work-
pieces 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.
• Use extra caution when making a "pocket cut" into exist-
ing walls or other blind areas. The protruding wheel may
cut gas or water pipes, electrical wiring or objects that
can cause kickback.
Safety warnings specific for sanding operations
• Do not use excessively oversized sanding disc paper. Fol-
low manufacturers recommendations, when selecting
sanding paper. Larger sanding paper extending beyond
the sanding pad presents a laceration hazard and may
cause snagging, tearing of the disc, or kickback.
Safety warnings specific for wire brushing
operations
• Be aware that wire bristles are thrown by the brush even
during ordinary operation. Do not overstress the wires
by applying excessive load to the brush. The wire bristles
can easily penetrate light clothing and/or skin.
• If the use of a guard is recommended for wire brushing,
do not allow any interference of the wire wheel or brush
with the guard. Wire wheel or brush may expand in
diameter due to work load and centrifugal forces.
Additional safety warnings
• Wear safety goggles.
• Use suitable detectors to determine if utility lines are
hidden in the work area or call the local utility company
for assistance. Contact with electric lines can lead to
fire and electric shock. Damaging a gas line can lead
to explosion. Penetrating a water line causes property
damage or may cause an electric shock.
• Release the On/Off switch and set it to the off position
when the power supply is interrupted, e. g., in case of
a power failure or when the mains plug is pulled. This
prevents uncontrolled restarting.
• Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
• Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than
by hand.

MAINTENANCE AND CLEANING

Make sure that the machine is not live when carry-
ing out maintenance work on the motor.
• Regularly clean the machine housing with a soft cloth,
preferably after each use. Keep the ventilation slots free
from dust and dirt.If the dirt does not come off use a soft
cloth moistened with soapy water. Never use solvents
such as petrol, alcohol, ammonia water, etc. These sol-
vents may damage the plastic parts.
• The machine requires no additional lubrication.
• Should a fault occur, e.g. after wear of a part, please
contact your local BORT GLOBAL LIMITED dealer.
