period of use, performance of the brake will decline due to the wearing and tearing of the brake plate. Then it
is necessary to adjust the clearance of the brake. As indicated in the drawing, first use the insert ruler to check
the clearance between the brake plate and magnetic steel. If the clearance is over 0.5mm, adjust it. Before the
adjustment, clean the dirt and dust on the friction plate. During adjustment, first loosen the fitting screw
2. Then adjust the length of the adjustment screws 1 and screw down the tightening screws. After the
adjustment, the clearance between brake plate and magnetic steel shall be kept between 0.2-03mm. During
the adjustment, make sure that the three tightening screws are adjusted evenly so as to ensure that the
clearance between brake plate and magnetic steel are distributed around equally. After the adjustment, turn
on the brake with 24v DC power. Then the brake will make clear sound.
