5. How to select tightening torque and rotational speed
Use
Machine screw
Driving
Wood screw
Wood
Drilling
Metal
CAUTION
○ The selection examples shown in Table 4 should be
considered as general standard. As diff erent types of
tightening screws and diff erent materials to be tightened
are used in actual works proper adjustments are naturally
necessary.
○ When using the driver drill with a machine screw at HIGH
(high speed), a screw may damage or a bit may loose
due to the tightning torque is too strong. Use the driver
drill at LOW (low speed) when using a machine screw.
6. Mounting and dismounting of the bit
(1) After inserting a driver bit, etc. into the keyless drill chuck,
fi rmly grasp the ring and tighten the sleeve by turning it
toward the right (in the clockwise direction as viewed
from the front) (See Fig. 9).
○ If the sleeve becomes loose during operation, tighten it
further. The tightening force becomes stronger when the
sleeve is tightened additionally.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by turning
it toward the left (in the counter-clockwise direction as
viewed from the front) (See Fig. 9).
7. Confi rm that the battery is mounted correctly
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. 10) (The
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. 11).
(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. 12

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.
5. Service parts list
CAUTION
Repair, modifi cation and inspection of Hitachi Power
Tools must be carried out by a Hitachi Authorized Service
Center.
This Parts List will be helpful if presented with the tool to
the Hitachi Authorized Service Center when requesting
repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each

MODIFICATIONS
Hitachi Power Tools are constantly being improved
and modifi ed to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without prior
notice.
