Warning: in case the electric power goes off, set
the switch to the off position, preventing the
machine from accidentally self starting.
Warning: do not touch the core bit after
performing a drill. The core bit can be very hot
and cause severe burns.
Mechanical clutch
Warning: the unexpected block of the core bit
rotation can cause a heavy tear at your arms.
The maximum force of this tear at your arms, accordingly with
the safety regulation, can not exceed 40 Kg. Be always ready
to resist this kind of force and to quickly release the switch.
Your CARDI core drill is equipped with a safety mechanical
clutch that comes into operation in case of sudden stop of the
core bit rotation. The block of the core bit rotation could be
dangerous for the operator so, despite your drill is equipped
with this device, you must always be watchful and be ready
to resist the tear and release the switch to off position.
Multifunction electronic
▪
the soft-start (peaks limiter) allows the motor to not
start at full power, reduces current peaks that occurs
when you switch the motor on, helps you when you
begin drilling, allowing gradual core bit rotation and
avoiding tears at your arm, and allows you to use
your core drill connected to the household electric
supply equipped with automatic circuit breaker;
▪
the electronic clutch cuts off power to the motor in
case of excessive overload, increasing the operator
safety and preventing damage to the motor. When
the overload is over, the device gives back power to
the motor that begins working again;
▪
if the electronic clutch operates frequently means
that the core drill is not used properly. Possible
causes can be a not suitable forward speed, an
excessive friction between the core bit and hole wall
or an excessive drilling depth.
Drilling deeper than the core bit length
If you want to make a hole deeper than the core bit length
proceed as follows:
▪
drill till the end of the core bit;
▪
pull the core bit out of the hole and remove the core;
▪
place a proper core bit extension between the core
bit and the core drill thread;
▪
insert the core bit in the hole and proceed drilling.
Maintenance - Service - Warranty
Periodic maintenance
▪
at the end of the work, after having removed the core
bit, blow compressed air inside the rotating motor in
order to remove dust and powder. Do this operation
wearing protective goggles;
▪
before starting any other cleaning, maintenance or
lubrication operation make sure that the core drill is
unplugged;
▪
