CAUTION
○ The selection examples shown in Table 4 should
be utilized as a 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. 8)
○ 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. 8)

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 11a n d then turn the sleeve
to the loose side (left side) while operating the clutch. It
should be easy
now to loosen the sleeve.
NOTE
○ There is a plus driver bit on side of the main unit.
The bit can be removed by pulling it forward. After using
the bit, make sure to fi rmly attach it to the main body
again.
7. Confi rm that the battery is mounted correctly.
8. Check the rotation direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the selector button. The
L-si de of the selector button is pushed to turn the bit
counterclockwise. (see Fig. 9). (The
and 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 peep sound may be 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 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
