English SAW BLADE MOUNTING AND DISMOUNTING WARNING: * To prevent an accident or personal injury, always turn off the trigger switch and disconnect the power plug from the receptacle before removing or installing a saw blade. If cutting work is done in a state where the bolt is not sufficiently tightened, the bolt can get loose, the blade can come off, and the lower guard can get damaged, resulting in injuries. Also, check that the bolts are properly tightened before plugging the power plug into the receptacle. * If the bolts are attached or detached using tools other than the 10mm box wrench (standard accessory), excessive or improperly tightening occurs, resulting in injury. 1. Mounting the saw blade (Fig. 47-a, Fig. 47-b, Fig. 47-c and Fig. 47-d) (1) Use the accessory 10mm box wrench to loosen the 6mm bolt fastening the spindle cover and then remove the spindle cover. (2) Press in spindle lock and loosen bolt with 10mm box wrench (standard accessory). Since the bolt is left-hand threaded, loosen by turning it to the right as shown in Fig. 47-c.
