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 away from front of the tool.
(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. 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.
R
L
(See Fig. 6) (The and
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.
2. 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.
3. Change rotation speed
As shown in Fig. 7, when the rotation switch-over lever is slid to the lower side,
the power mode (P) is set. And when slid to upper side, the save mode (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.
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.
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.
5. Number of screws tightenings possible
Please refer to the table below for the number of screw tightened possible
with one charge.
Screw used
BSL1430
Wood screw ø4 × 50
Approx. 900
(Soft wood)
Machine screw M8 × 16
Approx. 1990
These values may vary slightly, according to surrounding temperature and
battery characteristics.
6. Using the hook
The hook is used to hang up the power tool to your waist belt while
working.
marks are provided on the body.)
Battery
BSL1415 BSL1830
Approx. 450 Approx. 1400
Approx. 995 Approx. 3150
CAUTION:
When using the hook, hang up the power tool firmly 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 fit any
bit to the tip of power tool. If the sharp bit such as drill is fitted 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) Removing the hook.
Remove the screws fixing the hook with Philips screw driver. (Fig. 8)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power tool and tighten the screws
to fix the hook firmly. (Fig. 9)
7. About Remaining Battery Indicator
When pressing the remaining battery indicator switch, the remaining battery
indicator lamp lights and the battery remaining power can be checked. (Fig.
10) When releasing your finger from the remaining battery indicator switch,
the remaining battery indicator lamp goes off. The Table 4 shows the state of
remaining battery indicator lamp and the battery remaining power.
State of lamp Battery Remaining Power
The battery remaining power is enough.
The battery remaining power is a half.
The battery remaining power is nearly
empty.
Re-charge the battery soonest possible.
As the remaining battery indicator shows somewhat differently depending
on ambient temperature and battery characteristics, read it as a reference.
NOTE:
Do not give a strong shock to the switch panel or break it.It may lead to a trouble.
To save the battery power consumption, the remaining battery indicator
lamp lights while pressing the remaining battery indicator switch.
8. How to use the LED light
Every time you press the light switch on the switch panel, the LED light
lights or goes off. (Fig. 11)
To prevent the battery power consumption, turn off the LED light frequently.
CAUTION:
Do not expose directly your eye to the light by looking into the light.
If your eye is continuously exposed to the light, your eye will be hurt.
NOTE:
To prevent the battery power consumption caused by forgetting to turn off
the LED light, the light goes off automatically in about 15 minutes.

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work
(1) The power tool is equipped with a temperature protection circuit to protect
the motor. (WH18DSL)
Continuous bolt-tightening work may cause the temperature of the unit to
rise, activating the temperature protection circuit and automatically stopping
operation.
If this happens, allow the power tool to cool before resuming use.
(2) 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.
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.
