Prior To Operation; How To Use - Hitachi WH 12DAF Bedienungsanleitung

English
This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging
the batteries 2 – 3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the battery
and recharge it after it has cooled for a while.
CAUTION
If the battery has been heated right after operation
(or due to sunlight, etc.), the charger's pilot lamp may
not light in red. In such a case, first let the battery
cool, then start charging.
When the pilot lamp flikers in red quickly (at 0.2-
second intervals), check for and take out any foreign
objects in the charger's battery installation hole. If
there are no foreign objects, it is probable that the
battery or charger is malfunctioning. Take it to your
Authorized Service Center.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged with
UC14YFA, UC24YFA is taken out, wait for a minimum
of 3 seconds before reinserting it to continue charging.
If the battery is reinserted within 3 seconds, the battery
may not be properly charged.

PRIOR TO OPERATION

1. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it is at
all loose it could come off and cause an accident.
3. Installing the bit
Always follow the following procedure to install driver
bit (Fig. 5).
(1) Pull the guide sleeve forward.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve and it returns to its original
position.
CAUTION
If the guide sleeve does not return to its original
position, then the bit is not installed properly.

HOW TO USE

1. 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.
9
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. 6).
(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. 7).
(b) Remove the hook and spring (Fig. 8).
(c) Install the hook and spring on the other side and
securely fasten with screw (Fig. 9).
NOTE
Pay attention to the spring orientation. Install the
spring with larger diameter away from you (Fig. 9).
(3) Using the bit holder
Installing the bit
Slide the bit from the side in the direction of Fig.
10, 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. 11).
CAUTION
The bit may come loose from the hook and cause
bodily injury when reversing the direction of the bit
as shown in Fig. 10 or when using the driver with the
bit stored incomplete.
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.
2. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the push button.
The L-side of the push button is pushed to turn the bit
counterclockwise (See Fig. 12) (The
are provided on the body).
CAUTION
The push button can not 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. Tightening and loosening screws
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.
