NOMAD GO
6. MAINTENANCE
The NOMAD GO 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 includes the cutter, the brush, the
tracer and the belt.
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, 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.
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.
Only use original batteries and battery chargers.
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 machine
against oxidation, applying oil to the clamps, tracer,
rails, etc.
