SAVE THESE INSTRUCTIONS

Work Area

1.Keep your work area clean and well lit.

Cluttered benches and dark areas invite acci- dents.

2.Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

3.Keep bystanders, children, and visitors away while operating a power tool. Dis- tractions can cause you to lose control.

9.Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

10.Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations.

11.Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

Electrical Safety

4.A battery operated tool with integral bat- teries or a separate battery pack must be recharged only with the specified charger for the battery. A charger that may be suit- able for one type of battery may create a risk of fire when used with another battery.

5.Use battery operated tool only with specif- ically designated battery pack. Use of any other batteries may create a risk of fire.

Personal Safety

6.Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

7.Dress properly. Do not wear loose cloth- ing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

8.Avoid accidental starting. Be sure switch is in the locked or off position before inserting battery pack. Carrying tools with your finger on the switch or inserting the bat- tery pack into a tool with the switch on invites accidents.

Tool Use and Care

12.Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.

13.Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.

14.Do not use tool if switch does not turn it on or off. A tool that cannot be controlled with the switch is dangerous and must be repaired.

15.Disconnect battery pack from tool or place the switch in the locked or off posi- tion before making any adjustments, changing accessories, or storing the tool.

Such preventive safety measures reduce the risk of starting the tool accidentally.

16.Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

17.When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other small metal objects that can make a con- nection from one terminal to another.

Shorting the battery terminals together may cause sparks, burns, or a fire.

18.Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edge are less likely to bind and are easier to control.

19.Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool???s operation. If damaged, have the tool ser- viced before using. Many accidents are caused by poorly maintained tools.

20.Use only accessories that are recom- mended by the manufacturer for your model. Accessories that may be suitable for

one tool may create a risk of injury when used on another tool.

SERVICE

21.Tool service must be performed only by qualified repair personnel. Service or main- tenance performed by unqualified personnel may result in a risk of injury.

22.When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual.

Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of shock or injury.

Charging

1.Plug the battery charger into the proper AC voltage source. The charging light will flash in green color.

2.Insert the battery cartridge so that the plus and minus terminals on the battery cartridge are on the same sides as their respective markings on the charger. Insert the cartridge fully into the port so that it rests on the charger port floor.

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 remain lit steadily during charging.

4.When the charging light color changes from red to green, the charging cycle is complete.

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.

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

8

NOTE:

???The battery charger is for charging Makita battery cartridge. Never use it for other purposes or for other manufacturer???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 battery cartridge fully after discharging it completely and recharging a couple of times.

???If you charge a battery cartridge from a just operated tool or a battery cartridge which has been left in a location exposed to direct sunlight or heat 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 cools. The battery cartridge will cool faster if you remove the battery cartridge from the battery charger.

???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.

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 dis- charged.

Always stop tool operation and charge the battery car- tridge 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.

OPERATION

004452

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

Hold the tool firmly and place the socket over the bolt or nut. Turn the tool on and fasten for the proper fastening time.

NOTE:

???Never use the tool to tighten bolts or nuts for a fastening torque greater than the tool-fastening capacity. Such usage may result in damage of the anvil. This tool is intended for assembly and disassembly automotive components and is provided with 9.5 mm (3/8???) anvil.

???When fastening screw M8 (5/16???) or smaller, carefully adjust pressure on the switch trigger so that the screw is not damaged.

???Hold the tool pointed straight at the bolt or nut.

???Excessive fastening torque may damage the bolt/nut or socket. Before starting your job, always perform a test operation to determine the proper fastening time for your bolt or nut. Especially for the bolt smaller than M8 (5/16???), perform the above test operation to prevent the trouble on socket or bolt, etc.

???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.

The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench.

1.When the battery cartridge is discharged almost com- pletely, voltage will drop and the fastening torque will be reduced.

2.Socket

???Failure to use the correct size socket will cause a reduction in the fastening torque.

???A worn socket ( wear on the hex end or square end ) will cause a reduction in the fastening torque.

MAINTENANCE

1. Limit mark

1.Brush holder cap

2.Screwdriver

3.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.

4.The use of the universal joint or the extension bar some- what reduces the fastening force of the impact wrench. Compensate by fastening for a longer period of time.

5.The manner of holding the tool or the material of driving position to be fastened will affect the torque.

6.Operating the tool at low speed will cause a reduction in the fastening torque.

CAUTION:

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

Replacing carbon brushes

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 iden- tical carbon brushes.

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.

After replacing brushes, insert the battery cartridge into the tool and break in brushes by running tool with no load for about 1 minute. Then check the tool while running and elec- tric brake operation when releasing the switch trigger. If elec- tric brake is not working well, ask your local Makita service center for repair.

To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using

Makita replacement parts.
