DeWalt D28415 Traducido De Las Instrucciones Originales página 39

The on/off switch is equipped with an unlocking
switch.
To run the tool, depress the unlocking switch (b) and
subsequently operate the on/off switch (a).
Release the unlocking switch (b).
To stop the tool, release the switch.
WARNING: Do not switch the tool on
or off when under load.
Spindle Lock (fi g. 1)
The spindle lock (c) is provided to prevent the
spindle from rotating when installing or removing
wheels. Operate the spindle lock only when the tool
is turned off, unplugged from the power supply, and
has come to a complete stop.
NOTICE: To reduce the risk of damage
to the tool, do not engage the spindle
lock while the tool is operating. Damage
to the tool will result and attached
accessory may spin off possibly
resulting in injury.
To engage the lock, depress the spindle lock button
and rotate the spindle until you are unable to rotate
the spindle further.
Metal Applications
When using the tool in metal applications, make
sure that a residual current device (RCD) has been
inserted to avoid residual risks caused by metal
swarf.
If the power supply is shut off by the RCD, take the
tool to authorised D WALT repair agent.
E
WARNING: In extreme working
conditions, conductive dust can
accumulate inside the machine housing
when working with metal. This can
result in the protective insulation in the
machine becoming degraded with a
potential risk of an electrical shock.
To avoid build-up of metal swarf inside the machine,
we recommend to clear the ventilation slots on a
daily basis. See Maintenance.
Using Flap Discs
WARNING: Metal dust build-up.
Extensive use of flap discs in metal
applications can result in the increased
potential for electric shock. To reduce
this risk, insert an RCD before use
and clean the ventilation slots daily by
blowing dry compressed air into the
ventilation slots inaccordance with the
below maintenance instructions.
Rough Grinding
Never use a cutting disc for roughing.
The best roughing results are achieved when setting
the machine at an angle of 30° to 40° . Move the
machine back and forth with moderate pressure. In
this manner, the workpiece will not become too hot,
does not discolour and no grooves are formed.
Working Advice
Exercise caution when cutting slots in
structural walls.
Slots in structural walls are subject to the country-
specific regulations. These regulations are to be
observed under all circumstances.
Before beginning work, consult the responsible
structural engineer, architect or the construction
supervisor.
MAINTENANCE
Your D WALT power tool has been designed to
E
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
WARNING: To reduce the risk
of serious personal injury, turn
tool off and disconnect tool from
power source before making any
adjustments or removing/installing
attachments or accessories. Before
reconnecting the tool, depress and
release the trigger switch to ensure that
the tool is off. An accidental start-up can
cause injury.
Pop-off Brushes
The motor will be automatically shut off indicating
that the carbon brushes are nearly worn out and
that the tool needs servicing. The carbon brushes
are not user-serviceable. Take the tool to an
authorised D WALT repair agent.
E
Lubrication
Your power tool requires no additional lubrication.
