1 no order number, the cause of the problem processing method. Tube dirt deposition and block 2. Sector gear and small gear resistance is 3. 1 two gear wear too much, not mesh. Dirt, wash tube with steel dredge 2. Adjust the fit clearance to 3. Change the two gear rotary dull or beat 1 2 pointer. Transmission parts fit clearance is too small, not flexible drive 2. Transmission activity site had product between a corrupt, ineffective 3. Free end connected to the connecting rod is not flexible. 4. 1 pointer and dial with friction. Increasing the tolerance clearance, or gas appliance clock 2. Cleaning rust removal, in addition to dirt or replacement drive 3 pieces. Adjust the connection until flexible 4. Correct the pointer, thickening glass lining below 3 pointer smooth rotation is not 1. Tilt sector gear 2. Pointer shaft bending 3. Plywood bent 4. Strut tilt, cause the plywood not parallel 1 up and down. Correct or replace gear 2. Straightening needle shaft 3. Calibration plate straightness 4. Correction pillar, and subtract the gasket the splint parallel four pointer deviates from the accepted value of zero error value for more than 1. The transmission mechanism of the fastening screw loose 2. Spring tube 1 permanent deformation. Tighten the set screw 2. Reshipment pointer, if necessary, to replace the new spring tube 5 pointer cannot indicate limit scale 1. Small 2 ratio. 1 inappropriate position of spring tube welding. Move the hinged bolts into 2.
