8. Check the rotational direction
The bit rotates clockwise (viewed from the rear side) by
pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn the
bit counterclockwise (See Fig. 9) (The
marks are provided on the body).
9. Switch operation
○ When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
○ The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly
and increases as the trigger switch is pulled more.
NOTE
○ A buzzing noise is produced when the motor is about
to rotate; This is only a noise, not a machine failure.
10. Using the bit holder
CAUTION
○ Stow the bit in the specifi ed location on the tool. If the
tool is used with the bit stowed improperly, the bit may
fall and cause bodily injury.
○ Do not stow bits that are of a diff erent length, gauge
or dimension than the plus driver bit (65 mm long)
included in the STANDARD ACCESSORIES.
The bit may fall and cause bodily injury.
(1) Removing the bit
Securely hold the main unit and pull out the bit by
holding the tip with your thumb (Fig. 10).
(2) Installing the Bit
Install the bit with steps opposite of when removing.
Insert the bit so that the right and left sides are equal,
as shown in Fig. 11.

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Since use of as dull tool will degrade effi ciency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
3. Cleaning on the outside
When the driver drill is stained, wipe with a soft dry
cloth or a cloth moistened with soapy water. Do not use
chloric solvents, gasoline or paint thinner, for they melt
plastics.
4. Storage
Store the driver drill in a place in which the temperature
is less than 40°C and out of reach of children.
