1 1. Cap 2. Attachment 2 012896 NOTE: • When installing or removing the dust cup, the cap may come off the dust cup. At that time, proceed as follows. Remove the bellows from the attachment and fit the cap from the side shown in the figure with its carved side facing upward so that the groove in the cap fits in the inside periphery of the attachment. Finally, mount the bellows that has been removed. pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed. Set the action mode changing knob to the symbol. CAUTION: • There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole breakthrough, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury. NOTE: Eccentricity in the bit rotation may occur while operating the tool with no load. The tool automatically centers itself during operation. This does not affect the drilling precision. Blow-out bulb (optional accessory) 1. Blow-out bulb 014365 NOTE: • If you connect a vacuum cleaner to your hammer, cleaner operations can be performed. Dust cap needs to be removed from the dust cup before the connection. OPERATION Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations.
