2. Then release the sleeve to secure the bit.
3. To install the bit, insert the bit-piece and bit into the sleeve as far as it will go.
4. The bit piece should be inserted into the sleeve with its pointed end facing in.
5. Then release the sleeve to secure the bit.

To remove the bit, pull the sleeve in the direction of the arrow and pull the bit out firmly.

CAUTION
Do not touch the drill bit shortly after operating as it gets hot. Replace the drill bit after cooling it down.

NOTE
If the bit is not inserted deep enough into the sleeve, the sleeve will not return to its original position and the bit will not be secured. In this case, try re-inserting the bit according to the instructions above. After inserting the bit, make sure that it is firmly secured. If it comes out, do not use it.

Hook optional accessory

When installing the hook, tighten the screw firmly. Failure to do so may cause the breakage of the tool or personal injury. The hook is convenient for temporarily hanging the tool. This can be installed on either side of the tool.To install the hook, insert it into a groove in the tool hous-ing on either side and then secure it with a screw. To remove, loosen the screw and then take it out.

OERATION

Always insert the battery cartridge all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely. Install it fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you. If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.

Impact driver mode

When changing the action mode to the impact driver mode, always check that the tool impacts by tightening wood screws. If the action mode is not changed completely, the tool twists the operator’s hand resulting injury.

Screw driving

Hold the tool firmly and place the point of the driver bit in the screw head. Apply forward pressure to the tool to the extent that the bit will not slip off the screw and turn the tool on to start operation.

Tightening bolts

The proper fastening torque may differ depending upon the kind or size of the screw/bolt, the material of the workpiece to be fastened, etc. The relation between fastening torque and fastening time is shown in the figures.

NOTE
 When the action mode is set to impact driver mode, make sure that the tool impacts properly by fastening a wood screw before operation. If the tool does not work properly, contact your nearest Makita service center. Hold the tool pointed straight at the screw.  Use the proper bit for the head of the screw/bolt that you wish to use. When fastening screw M8 or smaller, carefully adjust pressure on the switch trigger so that the screw is not damaged. If you tighten the screw for a time longer than shown in the figures, the screw or the point of the driver bit may be overstressed, stripped, damaged, etc. Before starting your job, always perform a test operation to deter-mine the proper fastening time for your screw.

The fastening torque is affected by a wide variety of fac-tors including the following. After fastening, always check the torque with a torque wrench. When the battery cartridge is discharged almost completely, voltage will drop and the fastening torque will be reduced.

Driver bit or socket bit

• Failure to use the correct size driver bit or socket bit will cause a reduction in the fastening torque3 Bolt.
• Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of bolt.
• Even though the diameters of bolts are the same, the proper fastening torque will differ according to the torque coefficient, the class of bolt and the bolt length.
• The manner of holding the tool or the material of driving position to be fastened will affect the torque.
• Operating the tool at low speed will cause a reduction in the fastening torque.

Hammer drill mode

Always hold the tool firmly during operation. There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Be sure to use a tungsten-carbide tipped bit.
Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and pre-vent 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.

Drilling mode

• 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.
• A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out.
• However, the tool may back out abruptly if you do not hold it firmly.
• Always secure small workpieces in a vise or similar hold-down device.
• Do not pull the switch trigger repeatedly when the motor is locked.
• It may damage the tool.
• For drilling in wood, the best results are obtained with wood drills equipped with a guide screw.
• The guide screw makes drilling easier by pulling the bit into the workpiece.
• For 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 indentation and start drilling.
• Use a cutting lubricant when drilling metals.
• The exceptions are iron and brass which should be drilled dry.
  NOTE
  Choose suitable speed for the work load. Drilling over the following capacity may damage the tool.

Screwdriver mode

• Adjust the number on the LED display to the proper torque level for your work.
• Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged.
• Hold the tool firmly. When the clutch cuts in or refastening, a sudden twisting force may occur and it can twist your wrist.
• Place the point of the driver bit in the screw head and apply pressure to the tool. Start the tool slowly and then increase the speed gradually.

NOTE

• This tool employs an electronic clutch. The tool stops automatically when the clutch cuts in. To keep operating, release the switch trigger once
• When driving wood screws, predrill pilot holes to make driving easier and to prevent splitting of the workpiece.

The fastening torque rate will be different depends on materials. Make a test fastening to get the desired torque before operation.
