Prior To Operation; Operational Cautions - Hitachi WH 14DJL Bedienungsanleitung

(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 is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used, the
pilot lamp of the charger lights for 1 second, does not
light for 0.5 seconds (off for 0.5 seconds). In
case, fi rst let the battery cool, then start charging.
○ When the pilot lamp fl ickers (at 0.2-second intervals),
check for and take out any foreign objects in the charger's
battery connector. 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 confi rm that the battery being charged with
UC18YKSL / UC18YFSL 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

◯ Setting up and checking the work environment
Check if the work environment is suitable by the above
precautions.
HOW TO USE
1. Installing the bit
Always follow the following procedure to install driver bit.
(Fig. 4)
(1) Pull the guide sleeve forward.
(2) Insert the bit into the hexagonal hole in the socket.
(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.
2. Removing the bit
Please do the opposite point on the method of installing
bit.
3. Confi rm that the battery is mounted correctly
4. 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. 5) (The
provided on the body).
5. 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.
6. Using the light
Pull the trigger switch to light up the light. The light keeps
on lighting while the trigger switch is being pulled. The
light goes out after releasing the trigger switch. (Fig. 6)
CAUTION
Do not look directly into the light. Such actions could
result in eye injury.
7. 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 fi tting
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.
such a Tighten with this impact driver lined up straight with the
screw.
8. Tightening and loosening bolts
A hex. socket matching the bolt or nut must fi rst be
selected. Then mount the socket on the anvil, and grip
the nut to be tightened with the hex. socket.
Holding the wrench in line with the bolt, press the power
switch to impact the nut for several seconds.
If the nut is only loosely fi tted to the bolt, the bolt may turn
with the nut, therefore mistaking proper tightening. In this
case, stop impact on the nut and hold the bolt head with a
wrench before restarting impact, or manually tighten the
bolt and nut to prevent them slipping.
9. Using the hook (optional accessory)
The hook is used to hang up the power tool to your waist
belt while working.
CAUTION
◯ When using the hook, hang up the power tool fi rmly not to
drop accidentally.
If the power tool is dropped, it may lead to an accident.
◯ When carrying the power tool with hooked to your waist
belt, do not fi t any bit to the tip of power tool. If the sharp
bit such as drill is fi tted to the power tool when carrying it
with hooked to your waist belt, you will be injured.
◯ Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.
(1) Placing the hook and tightening the screws.
Install securely the hook in the groove of power tool and
tighten the screws to fi x the hook fi rmly. (Fig. 7)
(2) Removing the hook.
Remove the screws fi xing the hook with Philips screw
driver. (Fig. 8)

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.
and marks are
NOTE
Do not touch the metal parts, as it gets very hot during
continuous work.
2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently,
when the switch trigger is pulled only slightly (low speed
rotation) and the motor is stopped while continuously
driving in screws, the components of the electronic circuit
parts may overheat and be damaged.
3. Use a tightening time suitable for the screw
The appropriate torque for a screw diff ers according to
the material and size of the screw, and the material being
screwed etc., so please use a tightening time suitable for
the screw. In particular, if a long tightening time is used in
the case of screws smaller than M8, there is a danger of
the screw breaking, so please confi rm the tightening time
and the tightening torque beforehand.
