Operational Cautions - Hitachi WH 14DMR Mode D'emploi

Do not attach the tip tool except phillips bit to the tool
main unit when carrying the tool main unit with the
light equipped 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.
1. Using the light equipped hook
The light equipped 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 E toward you in the direction of
arrow (A) and turn in the direction of arrow (B)
(Fig. 5).
(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. 6).
(b) Remove the hook E and spring F (Fig. 7).
(c) Install the hook E and spring F on the other side
and securely fasten with screw (Fig. 8).
NOTE
Pay attention to the spring F orientation. Install the
spring F with larger diameter G away from you
(Fig. 8).
(3) Using as an auxiliary light
(a) Press the switch H to turn off the light.
If forgotten, the light will turn off automatically
after 15 minutes.
(b) The direction of the light can be adjusted within
the range of hook positions 1 – 5 (Fig. 9).
Lighting time
AAAA manganese batteries: approx. 15 hrs.
AAAA alkali batteries: approx. 30 hrs.
CAUTION
Do not look directly into the light.
Such actions could result in eye injury.
(4) Replacing the batteries
(a) Loosen the hook screw J with a phillips-head
screwdriver (No. 1) I (Fig. 10).
Remove the hook cover L by pushing in the
direction of the arrow (Fig. 11).
(b) Remove the old batteries and insert the new
batteries. Align with the hook indications and
position the plus (+) and minus (–) terminals
correctly (Fig. 12).
(c) Align the indentation in the hook E main body
with the protuberance of the hook cover L, press
the hook cover L in the direction opposite to that
of the arrow K shown in Fig. 11 and then tighten
the screw.
Use commercially available AAAA batteries
(1.5 V) O.
NOTE
Do not tighten the screw excessively. Such action
could strip the screw threads.
CAUTION
Failure to observe the following can result in battery
leakage, rust or malfunction.
Position the plus (+) and minus (–) terminals correctly.
Replace both batteries at the same time. Do not mix
old and new batteries.
Remove exhausted batteries from the hook
immediately.
Do not discard batteries together with normal trash
and do not throw batteries into fire.
Store batteries out of the reach of children.
Use batteries correctly in accordance with the battery
specifications and indications.
2. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the push button C.
The L-side of the push button is pushed to turn the bit
counterclockwise (See Fig. 4) (The
are provided on the body).
CAUTION
The push button cannot be switched while the impact
driver is turning. To switch the push button, stop the
impact driver, then set the push button.
3. Switch operation
When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
The rotational speed 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.
4. Change rotation speed
As shown in Fig.17, when the rotation switch-over
lever T is slid to the lower side, the power mode V (P)
is set. And when slid to upper side, the save mode U
(S) is set.
Please use the save mode (S) when you want to lower
Maximum tightening torque.
CAUTION
In the work of the save mode (S), avoid the continuous
screw-tightening as temperature of electronic
components of the converter switch increases.
5. Tightening and loosening screws (Impact driver)
Install the bit that matches the screw, line up the bit in
the grooves of the head of the screw, then tighten it.
Push the impact driver just enough to keep the bit
fitting the head of the screw.
CAUTION
Applying the impact driver for too long tightens the
screw too much and can break it.
Tightening a screw with the impact driver at an angle
to that screw can damage the head of the screw and
the proper force will not be transmitted to the screw.
Tighten with this impact driver lined up straight with
the screw.

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work
After use for continuous bolt-tightening work, rest
the unit for 15 minutes or so when replacing the
battery. The temperature of the motor, switch, etc.,
will rise if the work is started again immediately after
battery replacement, eventually resulting in burnout.
NOTE
Do not touch the protector, as it gets very hot during
continuous work.
