1. Wear ear protectors. Exposure to noise can cause

2. Use auxiliary handle(s), if supplied with the tool.

Loss of control can cause personal injury.

3. Hold the power tool by insulated gripping

surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock. Safety instructions when using long drill bits with rotary hammers

1. Always start drilling at low speed and with the bit

tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.

2. Apply pressure only in direct line with the bit

and do not apply excessive pressure. Bits can bend, causing breakage or loss of control, resulting in personal injury. Additional safety warnings

1. Wear a hard hat (safety helmet), safety glasses

and/or face shield. Ordinary eye or sun glasses are NOT safety glasses. It is also highly recommended that you wear a dust mask and thickly padded gloves.

2. Be sure the bit is secured in place before

3. Under normal operation, the tool is designed to

produce vibration. The screws can come loose easily, causing a breakdown or accident. Check tightness of screws carefully before operation.

4. In cold weather or when the tool has not been

used for a long time, let the tool warm up for a while 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.

10. Do not touch the bit, parts close to the bit, or

workpiece immediately after operation; they may be extremely hot and could burn your skin.

11. Some material contains chemicals which may be

toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

12. Always be sure that the tool is switched off and

the battery cartridge and the bit are removed before handing the tool to other person.

13. Before operation, make sure that there is no

buried object such as electric pipe, water pipe or gas pipe in the working area. Otherwise, the drill bit/chisel may touch them, resulting an electric shock, electrical leakage or gas leak.

14. Do not operate the tool at no-load unnecessarily.

4. When not using the battery cartridge, remove it

from the tool or the charger.

5. Charge the battery cartridge if you do not use it

for a long period (more than six months). FUNCTIONAL DESCRIPTION CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. Installing or removing battery cartridge (Fig. 1) CAUTION:

• Always switch off the tool before installing or removing of the battery cartridge.

• Hold the tool and the battery cartridge firmly when installing or removing battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury. To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge. To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it 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. CAUTION:

• Always install the battery cartridge 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.

• Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly. Battery protection system (Lithium-ion battery with star marking) (Fig. 2) Lithium-ion batteries with a star marking are equipped with a protection system. This system automatically cuts off power to the tool to extend battery life. The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

• Overloaded: The tool is operated in a manner that causes it to draw an abnormally high current. In this situation, release the trigger switch on the tool and stop the application that caused the tool to become overloaded. Then pull the trigger switch again to restart. If the tool does not start, the battery is overheated. In this situation, let the battery cool before pulling the trig- ger switch again.

• Low battery voltage: The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.8 Indicating the remaining battery capacity (Fig. 3) Only for battery cartridges with the indicator Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for a few seconds.

• Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

• The first (far left) indicator lamp will blink when the battery protection system works. Switch action (Fig. 4) CAUTION:

• Before inserting the battery cartridge into 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. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop. Lighting up the lamp (Fig. 5) CAUTION:

• Do not look in the light or see the source of light directly. Pull the switch trigger to light up the lamp. The lamp keeps on lighting while the switch trigger is being pulled. The light automatically goes out 10 – 15 seconds after the switch trigger is released. NOTE:

• Use a dry cloth to wipe the dirt off the lens of the lamp. Be careful not to scratch the lens of lamp, or it may lower the illumination.

• Do not use thinner or gasoline to clean the lamp. Such solvents may damage it. Reversing switch action (Fig. 6) This tool has a reversing switch to change the direction of rotation. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for counterclockwise rotation. When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled. CAUTION:

• Always check the direction of rotation before operation.

• Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool.

• When not operating the tool, always set the reversing switch lever to the neutral position. Selecting the action mode Rotation with hammering (Fig. 7) For drilling in concrete, masonry, etc., depress the lock button and rotate the action mode changing knob to the symbol. Use a tungsten-carbide tipped bit. Rotation only (Fig. 8) For drilling in wood, metal or plastic materials, depress the lock button and rotate the action mode changing knob to the m symbol. Use a twist drill bit or wood bit. CAUTION:

• Do not rotate the action mode changing knob when the tool is running. The tool will be damaged.

• To avoid rapid wear on the mode change mechanism, be sure that the action mode changing knob is always positively located in one of the action mode positions. 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.

• Hole saws 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. ASSEMBLY CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. Side grip (auxiliary handle) (Fig. 9) CAUTION:

• Always use the side grip to ensure operating safety. Install the side grip so that the teeth on the grip fit in between the protrusions on the tool barrel. Then tighten the grip by turning clockwise at the desired position. It may be swung 360° so as to be secured at any position. Bit grease Coat the bit shank head beforehand with a small amount of bit grease (about 0.5 – 1 g). This chuck lubrication assures smooth action and longer service life. Installing or removing the bit Clean the bit shank and apply bit grease before installing the bit. (Fig. 10) Indicator lamps Remaining capacity Lighted Off Blinking 75% to 100% 50% to 75% 25% to 50% 0% to 25% Charge the battery. The battery may have malfunctioned.9 Insert the bit into the tool. Turn the bit and push it in until it engages. If the bit cannot be pushed in, remove the bit. Pull the chuck cover down a couple of times. Then insert the bit again. Turn the bit and push it in until it engages. (Fig. 11) After installing, always make sure that the bit is securely held in place by trying to pull it out. To remove the bit, pull the chuck cover down all the way and pull the bit out. (Fig. 12) Depth gauge (Fig. 13) The depth gauge is convenient for drilling holes of uniform depth. Loosen the side grip and insert the depth gauge into the hole in the side grip. Adjust the depth gauge to the desired depth and tighten the side grip. NOTE:

• The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing. Dust cup (optional accessory) (Fig. 14) Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling operations. Attach the dust cup to the bit as shown in the figure. The size of bits which the dust cup can be attached to is as follows.

OPERATION Hammer drilling operation (Fig. 15) Set the action mode changing knob to the symbol. 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 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. CAUTION:

• 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. 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) (Fig. 16) After drilling the hole, use the blow-out bulb to clean the dust out of the hole. Drilling in wood or metal (Fig. 17 & 18) Use the optional drill chuck assembly. When installing it, refer to “Installing or removing the bit” described on the previous page. Set the action mode changing knob so that the pointer points to the m symbol. CAUTION:

• Never use “rotation with hammering” when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged. Also, the drill chuck will come off when reversing the tool.

• 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 twisting force exerted on the tool/bit at the time of hole breakthrough. 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. MAINTENANCE CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.

• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result. Replacing carbon brushes (Fig. 19, 20 & 21) Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes. Remove holder cap covers by inserting the slotted bit screwdriver into the recessed part in the tool and lifting it up. Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps. Remount the holder cap covers on the tool. To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
