III. OPERATION
Switch Operation
1.The speed increases with the amount of depression of the trigger. When beginning work, depress the trigger slightly to start the rotation slowly.
2.A feedback electronic controller is used to give a strong torque even in low speed.
3.The brake operates when the trigger is released and the motor stops immediately.
Reversing Lever Operation
(Forward (
), Switch lock, Reverse (
))
CAUTION: Do not operate reversing lever until rotation of the spindle comes to a complete stop. Shifting during rota- tion of the chuck may damage the tool.
1.For reverse rotation, set the lever to reverse. Check the direction of rotation before use.
2.After use, set the lever to its center position (switch lock). (Fig. 10)
Clutch Torque Setting
Adjust the torque to one of the 18 possible set- tings or " 
" position required to do the job. CAUTION: Test the setting before actual opera-
tion. Set the scale at this mark (
).
CAUTION: To eliminate excessive temperature increase of the tool surface, do not operate the tool continuously, that is consecutively replacing the battery packs.
•Do not close up vent holes on the sides of the body during operation. Otherwise, the machine function is adversely affected to cause a fail- ure
•Impact mechanism creates heat. Square drive and accessory become very hot. They may cause burns.
•Do not strain the tool(motor).
This may cause damage to the unit.
•Keep body or skin away from exhaust vent to avoid risk of being burned by hot air.

•The ambient temperature range is between 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the battery temperature is below 0°C (32°F), the tool may fail to function properly. In that case, charge the
•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 connection from one terminal to another.
Shorting the battery terminals together may cause sparks, burns or a fire.

Battery Pack Life
The rechargeable batteries have a limited life. If the operation time becomes extremely short after recharg- ing, replace the battery pack with a new one.
Note: Use under extremely hot or cold condi- tions will reduce operating capacity per charge.
Battery Recycling
ATTENTION:
For environmental protection and recycling of materials, be sure that it is disposed of at an officially assigned location, if there is one in your country.
Charging
Note: When you charge the battery pack for the first time, or after prolonged storage, charge it for about 24 hours to bring the battery up to full capacity.
Battery charger (EY0110)
1. Plug the charger into the AC outlet.
Note: Sparks may be produced when the plug is inserted into the AC power supply, but this is not a problem in terms of safety.
