8) EXTENSION CABLE SELECTION
The machines are factory fitted with a 3-metre length of cable having three conductors 1.5mm²
LIVE, NEUTRAL and EARTH. If it becomes necessary to fit an extension cable from the power source,
care must be taken in using a cable of adequate capacity. Failure to do so will result in a loss of
traction by the magnet and a reduction of power from the motor.
Should the mains cable become damaged and need replacing, please ensure this is carried out only be
an approved Rotabroach Engineer.
Assuming a normal AC supply of the correct voltage, it is recommended that the following extension
lengths shall not be exceeded:
For 110v supply: 3.5metres of 3 core x 1.5mm²
For230v supply: 26metres of 3 core x 1.5mm²
ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE CHANGING CUTTERS.
9) MOUNTING OF CUTTERS
▪ The machine has been made to accept cutters having 19.05mm (3/4”) dia. Weldon
shanks.
The following procedure is to be used when mounting cutters:
▪ Lay the machine on its side with feed handles uppermost, ensuring arbor is wound
down to its lowest point to enable access to socket screws RD4066.
▪ Take appropriate pilot and place through the hole in cutter shank. Insert shank of
cutter into bore of arbor, ensuring alignment of two drive flats with socket screws.
▪ Tighten both screws using hexagon key.
