Maintenance And Inspection - Hitachi Koki DS 9DM Mode D'emploi

English
CAUTION
The selection examples shown in Table 7 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, EB926H, EB930H,
EB1222HL, EB1226HL and EB1230HL 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. Using the hook
CAUTION
When using the hook, pay sufficient attention so that
the main equipment does not fall. If the tool falls,
there is a risk of accident.
Do not attach the tip tool except phillips bit to the tool
main unit when carrying the tool main unit with the
hook suspended from a waist belt.
Injury may result if you carry the equipment
suspended from the waist belt with sharp tipped
components such as drill bit attached.
The hook can be installed on the right or left side and the
angle can be adjusted in 5 steps between 0° and 80°.
(1) Operating the hook
(a) Pull out the hook toward you in the direction
of arrow (A) and turn in the direction of arrow
(B) (Fig. 9).
(b) The angle can be adjusted in 5 steps (0°, 20°,
40°, 60°, 80°).
Adjust the angle of the hook to the desired
position for use.
(2) Switching the hook position
CAUTION
Incomplete installation of the hook may result in
bodily injury when used.
(a) Securely hold the main unit and remove the
screw using a slotted head screwdriver or a coin
(Fig. 10).
(b) Remove the hook and spring (Fig. 11).
(c) Install the hook and spring on the other side and
securely fasten with screw (Fig. 12).
NOTE
Pay attention to the spring orientation. Install the
spring with larger diameter away from you (Fig. 12).
(3) Using the bit holder
Installing the bit
Slide the bit from the side in the direction of Fig. 13,
and then insert firmly until the groove on the bit locks
in the protruded section of the hook.
Removing the bit
Securely hold the main unit and pull out the bit by
holding the tip with your thumb (Fig. 14).
CAUTION
The bit may come loose from the hook and cause
bodily injury when reversing the direction of the
bit as shown in Fig. 13 or when using the driver
with the bit stored incomplete.

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Only Hitachi OPTIONAL ACCESSORIES plus driver
bits (Bit No. 2; Code No. 992671, Bit No. 3; Code
No. 992672) may be used. Do not use other bits
since they may come loose.
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. 15).
If the sleeve becomes loose during operation, tighten
it further.
The tightening force becomes stronger when the
sleeve is tightened additionally.
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front), and then take out the bit etc. (See Fig. 15).
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.
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.
This unit has automatic spindle-lock mechanism for
quick bit changes.
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. 16) (The
R
marks are provided on the body).
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.
A buzzing noise is produced when the motor is
about to rotate; This is only a noise, not a machine
failure.
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.
