DRILL PROTECTION GUARD
The machine is provided with a security micro drill guard.
Before pressing the starting push button, set the drill guard in
the working position, otherwise the machine will not start.
Note: If the guard is opened when operating the machine, the
machine will stop.
DO NOT REMOVE THE GUARD UNDER ANY
CIRCUMSTANCES.
ELECTRIC CONNECTION
The electric connection is a dangerous operation. This task must be carried out by trained
or authorized staff for such purpose.
WARNING: The electric cabinet of the machine does not include the
protection differential switch. The user must install an individual power
supply for the machine, including a protection differential switch or
0.300 amps sensibility and the earth connection.
The present machine has a 4 wire electric hose to connect it to the electric power supply
through a protection differential switch. Do always connect the PE protection wire first and
after that all the others. Connection voltage: the feature sheet shows the voltage the
machine must be connected to.
TOTAL POWER INSTALLED 1.5KW
WARNING: Once the electric connection has been made, make sure that the main spindle
turns clockwise and that the motor pump(if equiped on machine model) pumps the coolant
liquid. Should this not happen, invert the current inlet phases.
ATTENTION: In this machine, when the main power switch is placed at: “0”position, the
minimum tension auxiliary circuit remains under tension.
For minimum tension auxiliary circuit maintenance or reparation jobs, put first at “0”position
the protection differential switch to which the machine has been connected, should be at
“0” position, in this way, the whole machine electric circuits will remain without electric
tension.
