4.2 Periodic check
WARNING
Periodic check should be carried out by qualifiedprofessionals to ensure safety. The power of the switching box
and the cutting machine should be shut down before periodic check to avoid personal injury accidents such as
electric shock and burns. Due to the discharge of capacitors, checking should be carried out 5 minutes after the
machine is powered off.
Tips:
Safety
All maintenance and checking should be carry out after the power is completely cut off.
Make sure the power plug of the machine is pulled out before uncovering the cutting
machine.
When the machine is powered on, keep hands, hair and tools away from the moving
parts such as the fan to avoid personal injury or machine damage.
Periodic check
Check periodically whether inner circuit connection is in good condition (esp. plugs).
Tighten the loose connection. If there is oxidization, remove it with sandpaper and then
reconnect.
Check periodically whether the insulatinglayer of all cables isin good condition. If there is
any dilapidation, rewrap it or replace it.
Beware of static
In order to protect the semiconductor components and PCBs from the static damage,
please wear antistatic device or touch the metal part of the enclosure to remove static in
advance before contacting the conductors and PCBs of the machine internal wiring.
Keep it dry
Avoid rain, water and vapor infiltrating the machine. If there is, dry it and check the
insulation of the cutting machine (including that between the connections and that
between the connection and the enclosure) with an ohmmeter. Only when there are no
Check if the inner surface is damaged or
worn, and if the air hole is blocked.
Check if the surface is damaged, worn or
poorly lubricated.
Replace the swirl ring if the
surface is damaged or worn or
the air hole is blocked.
Replace the O-ring if it is worn
or
damaged.
Lubricate
O-ring by applying a thin layer of
organic silicon lubricant if it is
dry.
