Electrical Safety - DeWalt DWE490 Original Instructions Manual

d ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind, walk up
or kickback if the power tool is restarted in the workpiece.
e ) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces 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.
f ) Use extra caution when making a "pocket cut" into
existing 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
a ) Do not use excessively oversized sanding disc
paper. Follow manufacturer's 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
a ) 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.
b ) 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 Rules for Grinders
Do not use Type 11 (flaring cup) wheels on this tool.
•
Using inappropriate accessories can result in injury.
Always use side handle. Tighten the handle securely. The
•
side handle should always be used to maintain control of the
tool at all times.

WARNING: We recommend the use of a residual current
device with a residual current rating of 30mA or less.
Residual Risks
In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:
• Impairment of hearing.
• Risk of personal injury due to flying particles.
• Risk of burns due to accessories becoming hot
during operation.
• Risk of personal injury due to prolonged use.

Electrical Safety

The electric motor has been designed for one voltage only.
Always check that the power supply corresponds to the voltage
on the rating plate.
Your D WALT tool is double insulated in accordance
e
with EN60745; therefore no earth wire is required.

WARNING: 115 V units have to be operated via a fail-safe
isolating transformer with an earth screen between the
primary and secondary winding.
If the supply cord is damaged, it must be replaced only by
D WALT or an authorised service organisation.
e
nOTE: This device is intended for the connection to a power
supply system with maximum permissible system impedance
Zmax of 0.28 Ω at the interface point (power service box)
of user's supply. The user has to ensure that this device is
connected only to a power system which fulfills the requirement
above. If necessary, the user can ask the public power supply
company for the system impedance at the interface point.
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.

WARNING: No connection is to be made to the
earth terminal.
Follow the fitting instructions supplied with good quality plugs.
Recommended fuse: 13 A.
