8 所示o带凸起中心的垫圈(A)侧o其直径 和锯片的内径相同o而垫圈(B)的凹入侧必须和 锯片侧一致- *

3 种锯片附带了垫圈(A)o其内径分别为

16 毫米p20 毫米 和30 毫米-(购买电圆锯时o随 机附带有一种垫圈(A)-) 如果您的锯片内径与垫圈(A)的内径不一致o 请与您购买电圆锯的销售店联系- (4) 锯片应妥加安装o使锯片的箭头同锯盖上的箭头 对准- (5) 尽量用手指拧紧固定锯片的六角头螺栓-然后压 下锁紧杆o锁住主轴o并拧紧螺栓-

7 注意U ? 若使用附件以外的扳手o螺栓不能拧紧o故务 必使用附属的扳手- ? 连接电源线之前o应先检查锁紧杆回到原来位 置o锯片转动平顺- 维护和检查1. 检查锯片 使用钝锯片将会导致电动机故障o降低工作效 率o故发现磨损时应尽快加以磨快或更换新的- 2. 检查安装螺钉 要经常检查安装螺钉是否紧固妥善-若发现螺钉 了o应立即重新扭紧o否则会导致严重的事 故- 3. 电动机的维护 电动机绕线是电动工具的心脏部-应仔细检查有 无损伤o是否被油液或水沾湿- 4. 检查碳刷(图9) 马达使用碳刷o它是消耗部品o因为使用过久的 碳刷将会导致马达故障o用具有相同碳刷号的新 碳刷去更换旧的o碳刷编号用数字表示碳刷何时 用旧或接近於磨损极限o此外o要经常保持碳刷 清洁以及保证它在刷握里能自由滑动- ? 更换碳刷 用无头螺丝刀卸下碳刷盖o然后可以很容易地取 下碳刷- 5. 检查安全盖的作用并进行维修U 小心维护安全盖o使它保持正常作用-将安全盖 旋转部分周围积留的锯屑去除干净o然后在其滑 动部位涂上主轴油o以提高其性能- 6. 调整底座和锯片以保持垂直U 底座和锯片之间的角度已被调整为

90 度o但是o 这一垂直角度可能会由于某些原因而改变o请按 以下方式调整U (1) 将底座转向上方(图10)并拧松旋钮和蝶形螺栓 (图4(A)p图4(B))- (2) 将一把直角尺放在底座和锯片上o转动螺丝-移 动底座的位置以形成所需的正确角度- 注意:为求改进o本手册所载规格可能不预先通告 而径予更改-
