6. MAINTENANCE
The NOMAD BIT key cutting machine requires no particular
maintenance plan. Nonetheless, certain parts should be
checked regularly and eventually replaced once they beco-
me worn. This particularly refers to the cutter, the brush and
the tracer.
Maintenance operations should be carried out by qualified
professionals with the necessary protective equipment for
working safely. The instructions provided in this manual
should be followed carefully when performing any main-
tenance tasks and the following instructions should be
followed in general:
The machine should be switched off and discon-
nected from the power supply before starting any
maintenance operations. The operator should
make sure that nobody can access the machine.
Do not perform any maintenance operations
while the machine is in operation.
Original spare parts should always be used. The
CE mark is only guaranteed when original spare
parts supplied by the manufacturer are used.
After replacing a component, make sure that the
corresponding screws are in their correct position.
NEVER USE COMPRESSED AIR! We recommend
using the small brush supplied with the machine
for keeping the clamps and carriage assembly free
from metallic swarf.
We recommend using protective oil (WD40 or
similar) to protect the metal parts of the machi-
ne against oxidation, applying oil to the clamps,
tracer, rails, etc.
