Fasten Screws And Coupling - Yueming CMA0604-B-A Product Operation Manual

should adjust the synchronous belt at a proper tension. While adjust Y direction synchronous belt, it is to achieve
a proper ten for the synchronous belt and make the left and right synchronous belts at the same tension. Only by
this way, a stable transmission synchronous belt can be achieved to ensure a good carving and cutting effect of
the product.
Keep the synchronous belt away from oil, pr chemicals. Contact with acid, alkali, oil and organic solvent is
prohibited. Keep the synchronous belt dry and clean.
There is problem of aging with rubber of the synchronous belt. In case of serous aging (or abrasion), timely
replacing with a new one is required. Please note that synchronous belt wheel should also be replaced if to
replace the synchronous belt.
After using the synchronous belt for a certain period, loose belt and abrasion will also be caused, and then
timely replacement and lockup are needed. Please note that the new synchronous belt should match with the
synchronous belt wheel.

4.1.2 Fasten screws and coupling

After working for a certain period, the screws at movement joints and the coupling of the movement system
may be loosen causing low stability of mechanical movement. Therefore, during movement of the machine, you
should observe if there is abnormal sound or other abnormality with the movement parts. In case of problems
found, timely fastening and maintenance are needed. Meanwhile, the screws of the machine should be tightened
one by one with tool after a certain period of use. The first fixation should be performed roughly one month later
after using:
