A power source with voltage greater than that specified for the tool can result in SERIOUS INJURY to the user -as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage less than the nameplate rating is harmful to the motor. ADDITIONAL SAFETY RULES 1. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations. 2. Hold the tool firmly. 3. Keep hands away from rotating parts. 4. When drilling 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 into a "live" wire. 5. Do not leave the tool running. Operate the tool only when hand-held. 6. Do not touch the drill bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin. SAVE THESE INSTRUCTIONS. 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, place it in the chuck as far as it will go. Tighten the chuck by hand. Place the chuck key in each of the three holes and tighten clockwise. Be sure to tighten all three chuck holes evenly. To remove the bit, turn the chuck key counterclockwise in just one hole, then loosen the chuck by hand. Switch action Move the reversing switch lever to the "FWD" position for clockwise rotation or the "REV" position for counterclockwise. The trigger switch does not actuate if the reversing switch lever is in the neutral posi- tion. Tool speed is increased by increasing pres- sure on the trigger. To start the tool, simply pull the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the tool from the locked position, pull the trigger fully, then release it. A speed control screw is provided so that maximum tool speed can be limited (vari- able). Turn the speed control screw clock- wise for higher speed, and counterclock- wise for lower speed. CAUTION : 0 Before plugging in the tool, always check to see that the trigger switch actuates properly and returns to the "OFF" position when released. *Always check the direction of rotation before drilling. 0 Use the reversing switch lever only when the tool comes to a complete stop. Changing the direction of rotation before the tool stops may ruin the tool. When not operating the tool, keep the reversing switch lever in the neutral position. *Pulling the trigger hard when the reversing switch lever is in the neutral position can cause switch breakage. Drilling operation 0 Drilling in wood. When drilling holes in the wood, use a wood drill with a guide screw. The guide screw makes it bore naturally by itself, so you do not need to apply any pressure to the tool. Drilling in metal To prevent the bit from slipping when starting a hole, make an indentation with a center- punch and hammer at the point to be drilled. Place the point of the bit in the indenta- tion and start drilling. Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry. CAUTION : *Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. *There is a tremendous force exerted on the tool/bit at the time of hole break through. Hold the tool firmly and exert care when the bit begins to break through the workpiece. 0 Always grip the small workpiece firmly with a vise or a holding means. *A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool will pull away easily unless you hold it firmly before starting the tool. MA1 NTENANCE CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance. The tool will stop when the carbon brushes wear to a certain length. When this occurs, both carbon brushes should be replaced. To maintain product SAFETY and RELlAB1LITY, repairs, carbon brush inspection and replacement, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, a!ways using Makita replacement parts. OPTIONAL ACCESSORIES The accessories listed in this manual are available at an extra cost from your Makita distributor or Makita factory Service center Service centers are listed on the warranty card packed with your tool CAUTION These accessories or attachments are recommended for use with your Makita tool specified in this manual The use of any other accessories or attachments might present a risk of injury to persons The accessories or attachments should be used only in the proper and intended manner Chuck key Part No 763423-0 2 1 DrillChuckS 10 10 1 Fan52 3 1 Gear 11 1 Ball Bearing627Z 4 1 BallBaar...
