* There may be some differences in operation depending on shapes of screws and the
workpieces used.
Conduct a test before actual driving.
Soft-grip handle
The handle is widely covered with soft-touch elastomer (rubber-like soft resin). It is slip-resistant and
securely fits in the palm of a hand even if the gripping hand sweats.
Safe and secure lithium-ion batteries (Types BCL 1815 and BCL 1415)
The new 1.5 Ah Types BCL 1815 and BCL 1415 Lithium-ion Batteries were developed for light-duty work.
Both batteries are equipped with an overdischarge protection circuit, overload protection circuit, overheat
protection circuit and voltage monitoring circuit for each cell to prevent reduced battery service life due to
overdischarge (overuse) or overcharge (excessive charging). These protection circuits make it possible to
safely use the batteries.
Precautions on using the Types BCL 1815 and BCL 1415 Lithium-ion Batteries
The Types BCL 1815 and BCL 1415 Lithium-ion Batteries are both equipped with a protective function that
automatically stops output to prolong battery service life. The motor may stop automatically in any of cases
(1), (2) and (3) below, even if the switch is held down during operation. This is due to activation of the
protective function. The batteries are not faulty.
Protective function Source of trouble Corrective action
(1) Overdischarge
protection circuit
Drop in battery voltage to about:
12 V/BCL 1815
8 V/BCL 1415
Charge the battery immediately.
(2) Overload
protection circuit Heavy-duty work Release the switch and eliminate
the cause of the overload problem.
(3) Overheat
protection circuit
Continuous operation
or heavy-duty work
Remove the battery from the tool
and allow it to cool down.
New Ni-Cd batteries (Types BCC 1412 and BCC 1812)
The new 1.2 Ah Ni-Cd Batteries Types BCC 1412 and BCC 1812 were developed for light-duty work.
These batteries—the lowest-level Ni-Cd models of 14.4 V and 18 V batteries—are consequently easier to
purchase than other Ni-Cd batteries.

1. Safety Instructions
In the interest of promoting the safest and most efficient use of the Models DV 18DCL2, DV 18DVC2,
DV 14DCL2 and DV 14DVC2 Cordless Impact Driver Drills by all of our customers, it is very important
when concluding a sale that the salesperson carefully ensure that the buyer seriously recognizes the
importance of the Handling Instructions, and fully understands the precautions listed on the Caution Plate
and Nameplate attached to each tool.
A. Handling instructions
Salespersons must be thoroughly familiar with the Handling Instructions in order to give pertinent advice to
the customer. In particular, they must have a thorough understanding of the precautions on using cordless
tools that differ from those of ordinary electric power tools.
(1) Before use, ensure that the unit is fully charged.
New units are not fully charged. Even if the units were fully charged at the factory, long periods of
inactivity, such as during shipment, cause the storage battery to lose its charge. Customers must be
instructed to fully charge the unit prior to use.
(2) Connect the charger to an AC power outlet only.
Use of any other power source (e.g., DC outlet, fuel powered generator) will cause the charger to
overheat and burn out.
(3) Do not use any voltage-increasing equipment (e.g., transformer) between the power source and
the charger.
Using the charger with voltage higher than that indicated on the unit will result in malfunction.
(4) Conduct battery charging at an ambient temperature range of 10°C to 40°C (50°F to 104°F).
Special temperature-sensitive devices are employed in the charger to permit rapid charging. Ensure
that customers are instructed to use the charger at the indicated ambient temperature range. At
temperatures below 10°C (50°F) the thermostat will not function properly, and the storage battery may
be overcharged. At temperatures above 40°C (104°F), the storage battery cannot be sufficiently
charged. The optimum temperature range is 20°C to 25°C (68°F to 77°F).
(5) The battery charger should not be used continuously.
Charging more than three storage batteries in succession at high ambient temperature will cause the
temperature of coils on the transformer to rise, running the risk of the temperature fuse inserted inside
the transformer inadvertently melting. After charging one battery, please wait at least 15 minutes before
charging the next battery.
(6) Do not insert foreign objects into the air vents on the charger.
The charger case is equipped with air vents to protect internal electronic components against
overheating. Caution the customer not to drop or insert such foreign matter as metallic or flammable
objects into the air vents. This could cause electric shock, fire, or other serious hazards.
PRECAUTIONS ON SALES PROMOTION

-14-
(7) Do not attempt to disassemble the storage battery or the charger.
Special devices such as a thermostat are built into the storage battery and charger to permit rapid
charging. Incorrect parts replacement and/or wiring will cause malfunctions that could result in fire or
other hazards. Instruct the customer to bring these units to an authorized service center in the event
repair or replacement is necessary.
(8) Disposal of the storage battery
Ensure that all customers understand that the storage batteries should be returned to the Hitachi power
tool sales outlet or authorized service center when no longer capable of being recharged or repaired. If
thrown into a fire, the batteries may explode.
B. Caution plates
(1) The following cautions are listed on the nameplate attached to the main body of each tool.

2. Inherent Drawbacks of Cordless Impact Driver Drills Requiring
Particular Attention during Sales Promotion
The cordless impact driver drill offers many advantages; it can be used in places where no power source is
available, the absence of a cord allows easy use, etc. However, any cordless tool has certain inherent
drawbacks. Salespersons must be thoroughly familiar with these drawbacks in order to properly advise the
customer in the most efficient use of the tool.
A. Suggestions and precautions on efficient use of the tool
(1) Use the cordless impact driver drill for comparatively light work.
The motor output of battery driven cordless impact driver drills is rather low compared with conventional
electric power tools. Accordingly, they are not suitable for the continuous drilling of many holes in
succession, or for drilling into particularly hard material that imposes a heavy load. Salespersons should
recommend conventional electric power tools for such heavy work.
(2) Large-diameter holes should be drilled at low speed.
Instruct the customer that drilling large-diameter holes or performing other work that requires
particularly strong torque should be done at low speed. Because there is less torque at high speed,
attempting such work at high speed will not improve working efficiency.
(3) Do not insert a foreign object into body vent holes.
The body of this tool has vent holes for improved cooling efficiency. As a fan is built into the motor, a
foreign object inserted through a vent hole may cause failure. Please instruct customers to never insert
a foreign object into the vent holes.
(4) Use at thrust of 100 to 150 N (10 to 15 kgf, 22 to 23 lbs.)
The drilling speed of this unit does not accelerate even if the tool is pressed strongly against the
workpiece as when using a typical AC impact drill. Such operation will damage the drill bit, resulting in
not only poor working efficiency but also motor burnout.
(5) Avoid “locking” of the motor
Locking of the motor will generate an overload current that could result in motor burnout and/or rapid
battery deterioration. Salespersons should advise the customer to immediately release the switch and
stop operation if the motor becomes locked. (A jammed drill bit can be disengaged from the workpiece
material by setting the switch to reverse rotation, or by manually turning the main body of the tool.)
(6) Variation in amount of work possible per charge
Although the nominal chargeable capacity of the storage batteries used with the Models DV 18DCL2,
DV 18DVC2, DV 14DCL2 and DV 14DVC2 is 1.2 Ah or 1.5 Ah, the actual capacity may vary within 10%
of that value depending on ambient temperature during use and charging, and the number of times the
batteries have been recharged. It should be noted that other factors that may affect the amount of work
possible per charge are the working conditions (e.g., ambient temperature, type and moisture content of
the workpiece, sharpness of the drill bit) and the operational skill of the user.

-16-
(7) Precautions on the use of HSS drill bits
For example, although the Model DV 18DCL2 is designed for drilling capacities of 38 mm (1-1/2") in
wood, and 13 mm (1/2") in aluminum and mild steel, this capability is not as efficient as conventional
electric power tools. In particular, when drilling through aluminum material with a 13 mm (1/2") drill bit,
the drill tends to become locked when the drill bit penetrates a material. For this reason, the customer
should be cautioned to reduce the thrust on the main body of the drill when drilling completely through a
material to avoid locking the tool. Repeated locking of the drill causes excessive current to flow from the
battery, thereby not only reducing the amount of work possible per charge, but also running the risk of
motor burnout.
(8) Securely tighten the sleeve of the keyless chuck.
The keyless chuck may slip during operation when using a cylindrically shaped drill bit shank,
depending on the surface conditions, materials, and other factors. Please instruct customers to
retighten the keyless chuck more securely if the keyless chuck slips during operation. The holding force
of the keyless chuck increases as you increase the tightening force of the keyless chuck.
(9) Avoid continuous use.
Although the Models DV 18DCL2, DV 18DVC2, DV 14DCL2 and DV 14DVC2 can withstand continuous
operation under certain conditions, operating conditions differ depending on the workpiece material and
sharpness of the drill bit in use. Please instruct customers to avoid continuous use of the Models DV
18DCL2, DV 18DVC2, DV 14DCL2 and DV 14DVC2, and generally take about a 15 minute break
following a single charge operation.

-17-
Be sure to remove the storage batteries from the main body before servicing. Inadvertent triggering of the
switch with the storage battery connected imposes the danger of the motor accidently turning.
