English WARNING: A closed, two-sided cutting wheel guard is included with this tool and is required when using cutting wheels. Failure to use proper flange and guard can result in injury resulting from wheel breakage and wheel contact. See pages 14 and 15 for more information. MOUNTING CLOSED (TYPE 1) GUARD WARNING: To reduce the risk of serious personal injury, turn tool off and remove the battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. 1. Open the guard latch (V), and align FIG. 17 the lugs (T) on the guard with the slots on the hub (U). This will align the lugs U with slots on the gear case cover. Position the guard facing backward. 2. Push the guard down until the guard lug engages and rotates freely in the groove on the gear case hub. 3. Rotate guard (I) into desired working T position. The guard body should be V positioned between the spindle and the operator to provide maximum operator protection. 4. Close the guard latch to secure the guard on the gear case cover. You should be unable to rotate the guard I by hand when the latch is in closed position. Do not operate grinder with a loose guard or clamp lever in open position. 5. To remove the guard, open the guard latch, rotate the guard so that the arrows are aligned and pull up on the guard. NOTE: The guard is pre-adjusted to the diameter of the gear case hub at the factory. If, after a period of time, the guard becomes loose, tighten the adjusting screw (W) with the clamp lever in the closed position with guard installed on the tool. FIG. 18 W NOTICE: To reduce the risk of damage to the tool, do not tighten adjusting screw with clamp lever in open position. Undetectable damage to guard or mounting hub may result. MOUNTING CUTTING WHEELS WARNING: To reduce the risk of serious personal injury, turn tool off and remove the battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. CAUTION: Matching diameter threaded backing flange and clamp nut (included with tool) must be used for cutting wheels. 1. Place the unthreaded backing flange on spindle with the raised section (pilot) facing up. The raised section (pilot) on the backing flange will be against the wheel when the wheel is installed. 2. Place the wheel on the backing flange, centering the wheel on the raised section (pilot). 3. Install the threaded clamp nut with the raised section (pilot) facing away from the wheel. 4. Depress the spindle lock button and tighten clamp nut with a wrench. 5. To remove the wheel, depress the spindle lock button and loosen the threaded clamp nut with a wrench. 22
