The common faults and solutions of precision panel saws

Cause Solution Cannot boot
a. Grid interruption or a phase or several phase interruptions
b. Unopened main power switch
c. may be due to power supply quality, resulting in overload protection trip, and thermal relay can not be reset without cooling
d. The fuse of the operating circuit is damaged
e. Press emergency stop, stop button is not reset
f. If the sound of motor is heard, the blade will not rotate

a. Wait for the grid to restore power or reconnect all phases
b. Turn the main power switch to the "ON" position
c. Solve the power supply quality of the power grid; Solve the problem of machine overload, wait for thermal relay cooling reset before shutting down the main power switch lock, find out which fuse is broken, find out the reason, troubleshoot, replace the fuse again with the same load
d. Rotate the emergency stop button mushroom head to the right to restore it.
e. Check whether the belt machine is automatically stopped after the sawing process.

a. One or more phase power interruptions (eg fuse blown)
b. Overload protection trip due to blade too blunt or feed speed too fast
c. The fuse of the operating circuit is damaged

a. Exclude the reason of phase power failure, restart the machine
b. Change the blade or reduce the feed rate. After the thermal relay cools, restart.

c. Turn off the main power switch lock in advance, find out which fuse is damaged, find out the reason, troubleshoot, replace the fuse with the same load and start to hear severe slipping squeak. The belt between the motor and the saw shaft is too loose. Tensioning of the drive belt Normal rhythmic noise when sawing The drive belt between the motor and the saw shaft is too loose or the belt is damaged Re-tension the drive belt or replace the new belt and tension
