9. Is it acceptable to bend the metal finger
guard to get it under a ring?
10. I noticed that on the metal section of the
finger guard that is inserted under
the ring that a number of scuff marks
and gouges have appeared. Is it safe to
use the finger guard in this condition?
11. I noticed that the guide disc doesn't run
as smoothly along the groove in the
finger guards black plastic block as it did
when new. Does this indicate that the
guard needs replacing?
12. From the safety notice I see that after 10
minutes of continuous usage the ring
cutter has to be left to cool down for 15
minutes before it can be started up
again. Why is this necessary?
13. We have noticed that our ring cutter
has become rather noisy compared
to when it was new. Does this mean the
ring cutter motor is wearing out and
needs replacing? Is there anything we
can do to reduce the noise?

The guard is designed to be flexible.
With usage, scuff and gouge marks natu-
rally develop. The finger guard is safe to use
as a barrier still exists between the ring and
the patients skin. However if the guard has
been cut through it must be replaced.
No. This indicates that dried gel and metal
debris have formed a coating on the walls
of the groove in the guide block and need
removing by cleaning thoroughly.
This is a precautionary requirement. During
use heat builds up in the motor and over
time can reach a temperature where the
insulation on the motor windings starts to
break down. This can cause a short circuit
to develop resulting in the heating up of
the retaining springs in the battery cassette,
which at a certain temperature will collapse
and cut off the power to the motor.
A noisy motor does not automatically
indicate that the motor needs replacing. A
drop of lubricant on the drive shaft bearing
at the front of the motor and another on
the bearing at the back of the motor should
help to reduce noise.
