6)
Check if the water in compressed air filter fixed at the back of machine is drained
regularly
；
7)
Check if the gas pressure indicator lamp on the panel is ON. If it is not ON, check if
compressed gas pipe is well connected , and if the gas pressure is normal. When the
gas pressure is less than 0.3Mpa, the lamp is not ON.
8)
When the water cooling torch is applied, check if the water pressure indicator lamp
on panel is ON. If it is not ON, check if the cooling water current is normal.
9)
Check if the overheat indicator lamp on panel is ON. If yes, check if the temperature
relay on the radiator is damaged or not.
10)
Openthe machine top to check if the lead-typed fuse next to the control transformer
has been fused
