Bit-locking function

1.With the trigger switch not engaged and a screwdriver bit locked in place, the tool can be used as a manual screwdriver (up to 22.6 Nm, 230 kgf-cm, 199 in-lbs).

There will be a little play in the chuck, but this is not a malfunction.

2.This feature is handy for tightening screws that require more torque than the maximum torque of the driver (position on the clutch), for confirming the tightness of a screw or to loosen an extremely tight screw.

Speed Selection

Choose a low or high speed to suit the use.

The more the speed control trigger is pulled, the higher the speed becomes.

 

No load speed

Torque

LOW

80

- 550/min (rpm)

Strong

HIGH

300

- 2000/min (rpm)

Weak

CAUTION:

Check the speed selector switch before use.

Use at low speed when strong force is needed during operation.

(Using at high speed while a strong force is applied may cause a motor breakdown.)

Do not operate the speed selector switch (LOW-HIGH) while pulling on the speed control trigger. This can cause the rechargeable battery to wear quickly or damage the internal mechanism of the motor.

*See appendix for "RECOMMENDED SPEED SELECTION”.

For Appropriate use of Battery pack

Ni-MH Battery pack (EY9200/EY9201/EY9230/EY9231)

Charge the Ni-MH battery fully be- fore storage in order to ensure a longer service life.

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 battery until charging is completed for appropriate functioning of the battery.

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 togeth- er may cause sparks, burns or a fire.

When operating with a Ni-MH bat- tery pack, make sure the place is well-ventilated.

Battery Pack Life

The rechargeable batteries have a limited life. If operation time becomes extremely short after recharging, replace the battery pack with a new one.

Note:

Use under extremely hot or cold conditions 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 batteries up to full capacity.
