Maintenance And Inspection - Hitachi Koki DV 14DCL Instrucciones De Manejo

NOTE
The use of the battery EB1426H, EB1430H, BCL1415,
BCL1430, BCL1815, EBL1430, EB1826HL, EB1830HL
and EBM1830 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.
7. 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. 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 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.
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. 11). (The
marks are provided on the selector button.)
CAUTION
Always use this unit with clockwise rotation, when
using it as an impact drill.
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.
11. For drilling into brick
Excessive pressing force never increases drilling
speed. It will not only damage the drill tip or reduce
working efficiency, but could also shorten the service
life of drill bit. Operate the impact driver drill within
10-15 kg pressing force while drilling into brick.
12. 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
Securely hold the main unit and pull out the bit by
holding the tip with your thumb (Fig. 12).
(2) Installing the Bit
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. 13.
13. 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. 14).
(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
and using a slotted head screwdriver or a coin (Fig. 15).
L R
(b) Remove the hook and spring (Fig. 16).
(c) Install the hook and spring on the other side and
securely fasten with screw (Fig. 17).
NOTE
Pay attention to the spring orientation. Install the
spring with larger diameter away from you (Fig. 17).
(3) Using the bit holder (Hook with bit holder)
Installing the bit
Slide the bit from the side, 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. 18).
CAUTION
Only Hitachi STANDARD ACCESSORIES phillips bit
(No. 2 × 65L; Code No. 983006) may be used. Do not
use other bits since they may come loose.

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.
