neutral (N) wires to the earth
pin marked E or
WARNING: 115 V units have to
be operated via a fail-safe isolating
transformer with an earth screen between
the primary and secondary winding.
For 115 V units with a power rating exceeding 1500 W,
we recommend to fit a plug to BS4343 standard.

Using an extension cable

If an extension cable is required, use an approved
extension cable suitable for the power input of this
tool (see technical data). The minimum conduc tor size
2
is 1.5 mm . When using a cable reel, always unwind
the cable completely.

Inrush currents cause short-time voltage drops.
Under unfavourable power supply conditions, other
equipment may be affected.
If the system impedance of the power supply is lower
than 0.25 ø, disturbances are unlikely to occur.
