CAUTION: • Since excessive cutting may cause overload of the motor or difficulty in controlling the tool, the depth of cut should not be more than 15 mm (9/16") at a pass when cutting grooves with an 8 mm (5/16") diameter bit. • When cutting grooves with a 20 mm (13/16") diameter bit, the depth of cut should not be more than 5 mm (3/16") at a pass. When you wish to cut grooves more than 15 mm (9/16") deep with an 8 mm (5/16") diameter bit or more than 5 mm (3/16") deep with a 20 mm (13/16") diameter bit, make several passes with progressively deeper bit settings. Stopper block 1 1. Depth pointer 2. Screw 3. Stopper pole 4. Adjusting hex 2 3 bolt 5. Stopper block 4 5 009746 The stopper block has three adjusting hex bolts which raise or lower 0.8 mm (about 1/32") per turn. You can easily obtain three different depths of cut using these adjusting hex bolts without readjusting the stopper pole. Adjust the lowest hex bolt to obtain the deepest depth of cut, following the method of "Adjusting depth of cut". Adjust the two remaining hex bolts to obtain shallower depths of cut. The differences in height of these hex bolts are equal to the differences in depths of cut. To adjust the hex bolts, turn the hex bolts. The stopper block is also convenient for making three passes with progressively deeper bit settings when cutting deep grooves. CAUTION: • When using a bit having total length of 60 mm (2-3/8") or more, or edge length of 35 mm (1-3/8") or more, the depth of cut cannot be adjusted as previously mentioned. To adjust, proceed as follows: Loosen the lock lever and carefully adjust bit protrusion below the tool base to the desired depth of cut by moving the tool body up or down. Then retighten the lock lever to lock the tool body at that depth of cut. Keep the tool body locked at this position during use. Since the bit always protrudes from the tool base, be careful when handling the tool. Adjusting the lock lever 1. Lock lever 2. Screw 009745 1 2 The locked position of the lock lever is adjustable. To adjust it, remove the screw securing the lock lever. The lock lever will come off. Set the lock lever at the desired angle. After adjustment, tighten the lock lever clockwise. Switch action 1. Switch trigger 1 009747 CAUTION: • Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released. To start the tool, simply pull the switch trigger. Release the switch trigger to stop. ASSEMBLY CAUTION: • Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. Installing or removing the bit 009748 5
