Check the rotary cut blade regularly; if it is worn, please replace it to avoid the production of inferior products.

Examine the electrical wires once a week to ensure that all wires are tightly connected or covered with no dust;

examine the insulation resistance (less than 0.5 Ω) and grounding resistance (less than 4 Ω) at intervals of half a year.

Check the wear of thrust bearings in the distribution box at the 20th date from the start of running; if the gap 

excessively large, please replace it immediately.

Examine the screw and barrel after the equipment is put into use for half a year; if they are excessively worn, please replace the screw sets at the front.
