Maintenance And Inspection; Important - Hitachi DS 9DVB Mode D'emploi

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 tightning torque is too
strong. Use the driver drill at LOW (low speed)
when using a machine screw.
NOTE
The use of the battery EB9H, EB930H, EB1222HL,
EB1230HL, EB14H, EB1430H, EB18H and EB1830H
in a cold condition (below 0 degree Centigrade) can
sometimes result in the weakened tightening torque
and reduced amount of work.
a temporary phenomenon, and returns to normal
when the battery warms up.
6. Mounting and dismounting of the bit
(1) Mounting the bit
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front) to open the clip on the keyless chuck. After
inserting a driver bit, etc., into the keyless drill
chuck, 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
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front), and then take out the bit ect. (See Fig. 9)
NOTE
If the sleeve is tightened in a state where the clip
of the keyless chuck is opened to a maximum limit,
a click noise may occur. This is the noise that occurs
when the loosening of the keyless chuck is prevented
and is not a malfunction.
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 11 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. Automatic spindle-lock mechanism
This unit has automatic spindle-lock mechanism for
quick bit changes.
8. Confirm that the battery is mounted correctly.
9. 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
R
marks are provided on the body.)
10. 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.

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. 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 tempera
ture is less than 40°C and out of reach of children.
