10) EXTENSION CABLE SELECTION

The machine is factory fitted with a 9-3/4 foot length of cable having three conductors 14 AWGLIVE,

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.

Assuming a normal AC supply of the correct voltage, it is recommended that the following extension

lengths shall not be exceeded:

For 120V supply:3.5 metres (11.5 feet) of 3 core x 14 AWG

ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE CHANGING CUTTERS.

11) 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:

•

With the machine in the upright position, ensure the Arbor Assembly (48H590) is fully inserted

into Arbor Spindle (48H596).

•

Take appropriate pilot and place through the hole in cutter shank. Insert shank of cutter into

bore of Arbor Assembly, ensuring alignment of two drive flats with socket screws.

•

Tighten both screws using hexagon key.

12) AUTOFEED FUNCTION

The autofeed function is an efficient way of drilling that allows for multiple units to be operated at the

same time, by one operator. The Icecut 250Auto can be operated both manually and with the autofeed

function. The autofeed function can be used for core cutting up to 2"x 2"*, as well as twist drilling (1/2"-

1" only).

When operating the drill in autofeed mode, it must be set at one of the two following speeds depending

on the diameter of the cutter being used.Prior to starting the machine, the electronic speed controller

requires setting, if the electronic speed controller is set after starting the machine, the automatic

function will not perform correctly.
