The dampers in the main handle (d) absorb the
vibrations transmitted to the user. This improves user
comfort during the operation.
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 DEWALT tool is double insulated in
accordance with EN 60745; 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
by a specially prepared cord available through the
DEWALT service organisation.
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.
Using an Extension Cable
If an extension cable is required, use an approved
3–core extension cable suitable for the power input
of this tool (see Technical Data).The minimum
conductor size is 1.5 mm

; the maximum length
is 30 m.
When using a cable reel, always unwind the cable
completely.
