and burns. Due to the discharge of capacitors, checking should be carried out
5 minutes after the machine is powered off.

4.2 Periodic check

Tips:

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.

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 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.

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.
