5�2 Periodic check
WARNING!
Periodic check should be carried out by qualified professionals 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 carried 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 (especially plugs).
Tighten the loose connection. If there is oxidization, remove it with sandpaper and then reconnect.
Check periodically whether the insulating layer of all cables is in 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 vapour 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 abnormal phenomena anymore,
can the machine be used.
Put the machine into the original packing in dry location if it is not to be used for a long time.
Pay attention to maintenance
Periodic check should be carried out to ensure the long-term normal use of the machine. Be
careful when doing the periodic check, including the inspection and cleaning of the machine
interior.
Generally, periodic check should be carried out every 6 months, and it should be carried out
every 3 months if the cutting environment is dusty or with heavy oily smoke.
Beware of corrosion
Please clean the plastic parts with neutral detergent.
Daily checking of the cables:
Items
Checking requirements
Remarks
Earth cable
Whether the grounding wires (including workpiece
GND wire and cutting machine GND wire) break off.
If unqualified, tighten or replace the
components.
Cutting cable
Whether the insulating layer of the cable is worn, or
the conductive part of the cable is exposed.
Whether the cable is drawn by an external force.
Whether the cable connected to the workpiece is well
connected.
Use appropriate methods according to
the work site situation to ensure safety
and normal cutting.
