Otherwise, it will be worn out quickly. Therefore, check it regularly. The method is: press down the v-belt about 5 mm by thumb appropriately. Otherwise it needs to adjust. Adjust the V-belt regularly according to the following procedures: 1) pull the belt in the vertical direction of the wheel and the force must be in the middle of the two wheels.2) fix the four mounting bolts on the pedal of the motor. 3) Turn the adjust bolts and move the pedal of the motor to let the V-belt have proper degree of tightness. First adjustment is done after 3 months of the machine installed, afterwards, adjust every 6 months. When the V-belt is required to be replaced, so do a couple of V-belt with same size and specification.

After adjustment, refasten all bolts and nuts, examine again to be sure it is pretty good. (refer to item G7 of the < test certificate>. 3 2 3 00 A B 1 Fig. 1-10 Adjusting the headstock accuracy 7.4.3 Adjustment of main spindle bearings If the main spindle bearings gap is too big, it will influence the processing precision directly. There are two kinds of spindle accuracy that is radial run-out (item G5) and axial slip (item G6) which are guaranteed by front and hind bearings, and usually adjusted to be ready for use before leaving the manufacturer. If the spindle must be adjusted because of being knocked by tool rest or other reasons, please adjust the front and hind bearings of main spindle simultaneously and also separately as requirement. The method was shown in Fig.1-11, The front bearing adjustment: unfasten screw 3, adjust nut 4 as required then refasten the screw 3.The hind bearing adjustment: unfasten nut 1, adjust nut 2 as you need, and refasten nut 1.After adjusting the major bearings, let the machine run around 1 hour without loading, then examine its temperature increment. General temperature rise are 25℃-40℃. The temperature contrast between the front and hind bearings is usually less than 10℃. The temperature of spindle bearings is not allowed to exceed 70℃, otherwise, loosen the nut slightly.
