CAUTION
The selection examples shown in Table 5 should be
considered as general standard. As different types of
tightening screws and different 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 tightening torque is too strong. Use
the driver drill at LOW (low speed) when using a
machine screw.
NOTE
The use of the battery BCL1015 or BCL1030M in a
cold condition (below 0 degree Centigrade) can
sometimes result in the weakened tightening torque
and reduced amount of work. This, however, is a
temporary phenomenon, and returns to normal when
the battery warms up.
6. Mounting and dismounting of the bit
(1) Mounting the bit
After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve by
turning it toward the right (in the clockwise direction
as viewed from the front) (See Fig. 10).
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. 10).
CAUTION
When it is no longer possible to loosen the sleeve, use a
vise or similar instrument to secure the bit. Set the
clutch mode between 1 and 13, and then turn the
sleeve to the loose side (left side) while operating the
clutch. It should be easy now to loosen the sleeve.
7. Confirm 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. 6) (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.

For 3.8 mm or smaller
nominal diameter screws.
For 12 mm or smaller
diameters.
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.

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Since use of as dull tool will degrade efficiency 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. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. 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.
5. Storage
Store the driver drill in a place in which the
temperature is less than 40°C and out of reach of
children.
NOTE
Make sure that the battery is fully charged when
stored for a long period (3 months or more). The
battery with smaller capacity may not be able to be
charged when used, if stored for a long period.
6. Service parts list
CAUTION
Repair, modification 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
country must be observed.
