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
CAUTION: Always switch off the tool before installing or removing of the battery cartridge.
CAUTION: Hold the tool and the battery cartridge irmly when installing or removing battery  cartridge. Failure to hold the tool and the battery  cartridge irmly may cause them to slip off your hands  and result in damage to the tool and battery cartridge  and a personal injury.

1. Red indicator 
2. Button 
3. Battery cartridge

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.
CAUTION: 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

• Star marking
  • 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, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart.
  • If the tool does not start, the battery is overheated. In this situation, let the battery cool before turning the tool on 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.

Indicating the remaining battery capacity

Only for battery cartridges with "B" at the end of the model number

1. Indicator lamps 
2. Check button

Press the check button on the battery cartridge to indi-cate the remaining battery capacity. The indicator lamps light up for few seconds.

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

Switch action

Switch trigger
CAUTION: Before installing the battery car-tridge 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 front lamp

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 lamp goes out 10 -15 seconds after releasing the trigger.
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.

Reversing switch action

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 counterclockwise rotation. When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled.

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.
Installing or removing driver bit/socket bit
 

Use only driver bit/socket bit that has inserting portion shown in the igure. Do not use any other driver bit/ socket bit.

Procedure 1
For tool without one-touch type sleeve

1. Driver bit 
2. Sleeve

To install the driver bit, pull the sleeve in the direction of the arrow and insert the driver bit into the sleeve as far as it will go.  Then release the sleeve to secure the driver bit. For tool with one-touch type sleeve To install the driver bit, insert the driver bit into the sleeve as far as it will go.
Procedure 2
In addition to Procedure 1, insert the bit-piece into the sleeve with its pointed end facing in.

1. Driver bit 
2. Bit-piece 
3. Sleeve

To remove the driver bit, pull the sleeve in the direction of the arrow and pull the driver bit out.
NOTE: If the driver bit is not inserted deep enough into the sleeve, the sleeve will not return to its original position and the driver bit will not be secured. In this case, try re-inserting the bit according to the instruc-tions above.
NOTE: When it is dificult to insert the driver bit, pull  the sleeve and insert it into the sleeve as far as it will go.
NOTE: After inserting the driver bit, make sure that it  is irmly secured. If it comes out, do not use it.

Installing hook

1. Groove 
2. Hook 
3. Screw

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 housing on either side and then secure it with a screw. To remove, loosen the screw and then take it out.

OPERATION

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 igures.
Proper fastening torque for standard bolt

1. Fastening time (second) 
2. Fastening torque

Proper fastening torque for high tensile bolt

1. Fastening time (second) 
2. Fastening torque

Hold the tool irmly 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.
NOTICE

• If you use a spare battery to continue the operation, rest the tool at least 15 min.
• Use the proper bit for the head of the screw/bolt that you wish to use.
• When fastening M8 or smaller screw, carefully  adjust pressure on the switch trigger so that the screw  is not damaged.
• Hold the tool pointed straight at the screw.
• If the impact force is too strong or you tighten  the screw for a time longer than shown in the figure ,  the screw or the point of the driver bit may be over-stressed, stripped, damaged, etc. Before starting your  job, always perform a test operation to determine the  proper fastening time for your screw.

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 completely, voltage will drop and the fastening torque will be reduced.
2. Driver bit or socket bit 
   Failure to use the correct size driver bit or socket bit will cause a reduction in the fastening torque.
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 manner of holding the tool or the material of driving position to be fastened will affect the torque.
5. Operating the tool at low speed will cause a reduction in the fastening torque.

MAINTENANCE

CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
NOTICE: Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
Replacing carbon brushes
