6. MAINTENANCE
The NOMAD BIT GO key cutting machine requires no parti-
cular maintenance plan. Nonetheless, certain parts should
be checked regularly and eventually replaced once they
become worn. This particularly refers to the cutter, the brush
and the tracer.
We recommend disconnecting the battery if the machine is
not going to be used for an extended period of time.
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:
Before starting any maintenance work. The opera
tor should make sure that nobody can access the
machine.
Switch off the power switch (11), switch off the
master switch (15), close the protective screen (16)
and check that the machine is NOT connected to
the battery charger.
Only use original batteries and battery chargers.
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.
