Maintenance And Inspection - Hitachi Koki DS 14DCL Handling Instructions Manual

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 BCL1415 and BCL1815 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) 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. 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 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. 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. 9) (The
R
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 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 specified 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 different 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

by holding the tip with your thumb (Fig. 10).
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. 11.
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.
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.
