tions and cautionary markings on (1) battery charger, (2) battery, and (3) product using bat- tery.

3. CAUTION — To reduce risk of injury, charge only

MAKITA type rechargeable batteries. Other types of batteries may burst causing personal injury and damage.

4. Do not expose charger to rain or snow.

5. Use of an attachment not recommended or sold

by the battery charger manufacturer may result in a risk of fire, electric shock, or injury to per- sons.

6. To reduce risk of damage to electric plug and

cord, pull by plug rather than cord when discon- necting charger.

7. Make sure cord is located so that it will not be

stepped on, tripped over, or otherwise subjected to damage or stress.

8. Do not operate charger with damaged cord or

plug — replace them immediately.

9. Do not operate charger if it has received a sharp

blow, been dropped, or otherwise damaged in any way; take it to a qualified serviceman.

10. Do not disassemble charger or battery cartridge;

take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire.

11. To reduce risk of electric shock, unplug charger

from outlet before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.

2. Do not attempt to use a step-up transformer, an

engine generator or DC power receptacle.

3. Do not allow anything to cover or clog the

4. Do not short the battery cartridge:

(1) Do not touch the terminals with any conduc- tive material. (2) Avoid storing battery cartridge in a container with other metal objects such as nails, coins, etc. (3) Do not expose battery cartridge to water or rain. A battery short can cause a large current flow, overheating, possible burns and even a break- down.

5. Do not store the tool and battery cartridge in

locations where the temperature may reach or exceed 50°C (122°F).

6. Do not incinerate the battery cartridge even if it

is severely damaged or is completely worn out. The battery cartridge can explode in a fire.

7. Be careful not to drop, shake or strike battery.

8. Do not charge inside a box or container of any

kind. The battery must be placed in a well venti- lated area during charging.6

1. Be aware that this tool is always in an operating

condition, because it does not have to be plugged into an electrical outlet.

2. Hold tool by insulated gripping surfaces when

performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

3. Wear ear protectors when using the tool for

extended periods. Prolonged exposure to high intensity noise can cause hearing loss.

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

and/or face shield. It is also highly recom- mended that you wear a dust mask and thickly padded gloves.

5. Be sure the bit is secured in place before opera-

6. 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.

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

used for a long time, let the tool warm up for sev- eral minutes by operating it under no load. This will loosen up the lubrication. Without proper warm-up, hammering operation is difficult.

8. Always be sure you have a firm footing.

9. Be sure no one is below when using the tool in

10. Hold the tool firmly with both hands.

11. Keep hands away from moving parts.

12. Do not leave the tool running. Operate the tool

only when hand-held.

13. Do not point the tool at any one in the area when

operating. The bit could fly out and injure some- one seriously.

14. 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. OPERATING INSTRUCTIONS Installing or removing battery cartridge (Fig. 1)

• Always switch off the tool before insertion or removal of the battery cartridge.

• To remove the battery cartridge, withdraw it from the tool while sliding the button on the cartridge.

• To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Always insert it all the way until it locks in place with a little click. If you can see the red part on the upper side of the button, it is not locked completely. Insert it fully until the red part cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.

• Do not use force when inserting the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly. Charging (Fig. 2)

1. Plug the battery charger into your power source. Two charging lights will flash in green color repeatedly.

2. Insert the battery cartridge into charger until it stops adjusting to the guide of charger. Terminal cover of charger

can be opened with inserting and closed with pulling out the battery cartridge.

3. When the battery cartridge is inserted, the charging light color will change from green to red and charging will

begin. The charging light will keep lighting up lit steadily during charging. One red charging light indicates charged condition in 0 – 80% and two red ones indicates 80 –100%.

4. With finish of charge, the charging lights will change from two red ones to two green ones.

5. If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch into its “trickle charge (maintenance charge)” mode which will last approximately 24 hours.

6. After charging, unplug the charger from the power source.

Cooling system (DC24SA only)

• This charger is equipped with cooling fan for heated battery in order to enable the battery to prove its own perfor- mance. Sound of cooling air comes out during cooling, which means no trouble on the charger.

• Yellow light will flash for warning in the following cases. – Trouble on cooling fan – Incomplete cool down of battery, such as, being clogged with dust The battery can be charged in spite of the yellow warning light. But the charging time will be longer than usual in this case. Check the sound of cooling fan, vent on the charger and battery, which can be sometime clogged with dust.

• The cooling system is in order although no sound of cooling fan comes out, if the yellow warning light will not flash.

• Always keep clean the vent on charger and battery for cooling.

• The products should be sent to repair or maintenance, if the yellow warning light will frequently flash. Battery type Capacity (mAh) Number of cells Charging time (DC24SA) Charging time (DC24WA) BH2420 (Ni-MH) 2000 20 Approx. 30 min. Approx. 55 min. BH2433 (Ni-MH) 3300 20 Approx. 60 min. Approx. 90 min.7 Conditioning charge (DC24SA only) Conditioning charge can extend the life of battery by automatically searching the optimum charging condition for the batteries in every situation. The battery employed in the following conditions repeatedly, will be worn out shortly, and yellow warning light may flash.

1. Recharge of battery with its high temperature

2. Recharge of battery with its low temperature

3. Recharge of full charged battery

4. Over-discharge of battery (contunue to discharge battery in spite of down of power.)

5. Recharge under broken cooling system

The charging time of such battery is longer than usual. Trickle charge (Maintenance charge) If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will switch into its “trickle charge (maintenance charge)” mode and keep the battery cartridge fresh and fully charged. Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely discharged.

Always stop tool operation and charge the battery cartridge when you notice less tool power.

2. Never recharge a fully charged battery cartridge.

Overcharging shortens the battery service life.

3. Charge the battery cartridge with room temperature at 10°C –40°C (50°F –104°F).

Let a hot battery cartridge cool down before charging it.

4. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.

• The battery charger is for charging Makita-battery cartridge. Never use it for other purposes or for other manufac- turer’s batteries.

• When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of time, it may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the bat- tery cartridge fully after discharging it completely and recharging a couple of times.

• If you charge a battery cartridge from a just-operated tool or battery cartridge which has been left in a location exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait for a while. Charging will begin after the battery cartridge is cooled by the cooling fan installed in the charger (DC24SA only). When the temperature on battery is more than approx. 70°C, two charging lights may flash in red color, and when approx. 50°C – 70°C, one charging light in red color.

• If the charging light flashes alternately in green and red color, charging is not possible. The terminals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.

• Any of the following conditions indicates damage to the charger and/or battery cartridge. Ask your Makita Authorized or Factory Service Center to check them.

1) The charging light does not flash (green) when the battery charger is plugged into a power source.

2) The charging light does not light up or flash (red) when the battery is inserted in the charger port.

3) Charging is not completed at even more than two hours after red light comes ON at start of charging.

Switch action (Fig. 3) 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 trigger. Tool speed is increased by increasing pressure on the trigger. Release the trigger to stop. Reversing switch action (Fig. 4) 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. 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 counter- clockwise rotation. When the switch lever is in the neutral position, the switch trigger cannot be pulled. Selecting action mode Rotation with hammering (Fig. 5) For drilling in concrete, masonry, etc., depress the lock button and rotate the change lever so that the pointer points to the H symbol. Use a tungsten- carbide tipped bit. Rotation only (Fig.6) For drilling in wood, metal or plastic materials, depress the lock button and rotate the change lever so that the pointer points to the

symbol. Use a twist drill bit or wood bit. Hammering only (Fig.7) For chipping, scaling or demolition operations, depress the lock button and rotate the change lever so that the pointer points to the

symbol. Use a bull point, cold chisel, scaling chisel, etc. CAUTION:

• Do not rotate the change lever when the tool is running. The tool will be damaged.

• To avoid rapid wear on the mode change mechanism, be sure that the change lever is always positively located in one of the three action mode positions.8 Installing or removing bit Important: Always be sure that the tool is switched off and the bat- tery cartridge is removed before installing or removing the bit. Clean the bit shank and apply the bit grease provided to it before installing the bit. (Fig. 8) Insert the bit into the tool. Turn the bit and push it in until it engages. (Fig.9) 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. 10) 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. 11) Depth gauge (Fig. 12) The depth gauge is convenient for drilling holes of uni- form depth. Loosen the clamp screw and adjust the depth gauge to the desired depth. After adjusting, tighten the clamp screw firmly. NOTE: The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing/motor housing. Side grip (Fig. 13) CAUTION: Always use the side grip to ensure operating safety when drilling in concrete, masonry, etc. 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. Bit angle (when chipping, scaling or demolishing) Important: Always be sure that the tool is switched off and the bat- tery cartridge is removed before changing the bit angle. To change the bit angle, depress the lock button and rotate the change lever so that the pointer points to the

symbol. Turn the bit to the desired angle. (Fig.14) Depress the lock button and rotate the change lever so that the pointer points to the

symbol. (Fig. 15) Then make sure that the bit is securely held in place by turning it slightly. Operation CAUTION:

• Always insert the battery cartridge all the way until it locks in place. If you can see the red part on the upper side of the button, it is not locked completely. Insert it fully until the red part cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.

• When operating overhead, always make sure the bat- tery cartridge is locked securely so that it will not be fallen out of the tool. If not, it may accidentally fall out of the tool, causing injury to you or someone around you. Hammer drilling operation (Fig. 16) Set the change lever to the H symbol. Position the bit at the location for the hole, then pull the 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 from the hole. By repeating this several times, the hole will be cleaned out. CAUTION:

• When the bit begins to break through concrete or if the bit strikes reinforcing rods embedded in concrete, the tool may react dangerously. Maintain good balance and safe footing while holding the tool firmly with both hands to prevent dangerous reaction. 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. Chipping/Scaling/Demolition (Fig. 17) Set the change lever to the

symbol. Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency. Drilling operation (Fig. 18) Use the optional drill chuck assembly. When installing it, refer to “Installing or removing drill bit” described on the previous page. You can drill up to 13 mm diameter in metal and up to 27 mm diameter in wood. Set the change lever so that the pointer points to the

symbol. Use a cutting lubricant when drilling metals. The excep- tion is 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 perfor- mance and shorten the service life of the tool.

• SDS Plus Tungsten-carbide tipped bit

• Plastic carrying case

• Dust extractor attachment
