manual abstract
The screws can come loose easily, causing a breakdown or accident. Check tightness of screws carefully before operation. 4. Incold weather or when the tool has not been used for a long time, let the tool warm up for several minutes by operating it under no load. This will loosen up the lubrication. Without proper warm-up, hammering operation is difficult. 5. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations. 6. Hold the tool firmly with both hands. 7. Keep hands away from moving parts. 8. Do not leave the tool running. Operate the tool only when hand-held. 9. Do not point the tool at any one in the area when operating. The bit could fly out and injure someone seriously. IO. When drilling or chipping into walls, floors or wherever "live" electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL! Hold the tool by the insulated grasping surfaces to prevent electric shock if you drill or chip into a "live" wire. 11. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin. SAVE THESE INSTRUCTIONS. Bit grease Coat the bit shank head beforehand with a small amount (about 0.5-1 g; 0.02-0.04'0z.) of bit grease. This chuck lubrication assures smooth action and longer service life. Installing or removing drill bit CAUTION: Always be sure that the tool is switched off and unplugged before installing or removing the bit. To install the bit, turn the change ring in the direction of the arrow until the a Key groove Rubber cap mark on the change ring is aligned with the Imark on the rubber cap. Align the key groove on the bit shank with the mark on the rubber cap and insert the bit. Turn the change ring in the direction of the Rubber cap Change ring arrow until the amark on the change ring is aligned with the 8 mark on the rubber cap to secure the bit. Adjusting depth of drilling Wing bolt Loosen the wing bolt and adjust the depth I gauge to the desired depth. After adjusting, tighten the wing bolt. Side grip (auxiliary handle) The side grip swings around to either side, allowing easy handling of the tool in any position. Loosen the side grip by turning it counterclockwise, swing it to the desired position and then tighten it by turning clockwise. Switch action Tool speed is increased by increasing pres- sure on the trigger. To start the tool, simply Higher _Lower pull the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop Speed control screw the tool from the locked position, pull the trigger fully, then release it. A speed con- Lock button trol screw is provided so that maximum tool speed can be limited (variable). Turn the speed control screw clockwise for higher speed, and counterclockwise for lower speed. CAUTION: Before plugging in the tool, always check to see that the trigger switch actuates properly and returns to the "OFF" position when released. Reversing switch action This tool has a reversing switch to change the direction of rotation. Move the revers- ing switch lever to the &>position for clockwise rotation or the 4%)position for counterclockwise. CAUTION: *Always check the direction of rotation before dril Iing. *Use the reversing switch only when the tool comes to a complete stop. Changing the direction of rotation before the tool stops may ruin the tool. Torque limiter The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning. CAUTION : *As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool. 0 Hole saws, core bits, diamond core bits, etc. cannot be used with this tool. They tend to pinch or catch easily in the hole. This will cause the torque limiter to actuate too frequently . Hammer drilling operation *Position the bit at the location for the hole, then pull the trigger. . -I--- Do not force the tool. Light pressure gives best results. Keep the tool in posi- tion and prevent it from slipping away from the hole. / *Do not apply more pressure when the hole becomes clogged with chips or par- ticles. Instead, run the tool at an idle, then remove from the hole. By repeating this several times, the hole will be cleaned out. Dust cup Use the dust cup to prevent dust from fall- ing over the tool and on yourself when -Bit performing overhead drilling operations. Attach the dust cup to the bit as shown in the figure. The dust cup can be attached to the bit up to 14.5 mm (9/16') in diameter. CUP Drilling in wood or metal Use the optional drill chuck assembly (con- sisting of drill chuck, chuck adapter and screw) for drilling up to 13 mm (1/2") in metal and up to 18 mm (1 1/16") in wood. To install it, refer to "installing or remov- ing drill bit". Drill chuck CAUTION: Be sure to use only the drill chuck assembly or chuck adapter a...
