* 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.

(3)

Protective function

Overdischarge protection circuit

Overload protection circuit

Overheat protection circuit

Source of trouble

Drop in battery voltage to about:

12 V/BCL 1815

8 V/BCL 1415

Heavy-duty work

Continuous operation or heavy-duty work

Corrective action

Charge the battery immediately.

Release the switch and eliminate the cause of the overload problem.

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.

PRECAUTIONS ON SALES PROMOTION

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.

-13-

(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.

[For the USA and Canada]

Warning

• To reduce the risk of injury, user must read Instruction Manual.

AVERTISSEMENT

• Afin de réduire le risque de blessures, I’utilisateur doit lire le mode d’emploi.

(2) The following cautions are listed on the nameplate attached to each storage battery.

[For Europe]


(3) The following cautions are listed on the nameplate attached to the Model UC 18YK Charger.

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.

-15-

(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.

-16-

(e) Check for proper operation of the Clutch Dial [4] and Shift Knob [37].

When the reassembly procedure up to step (d) is completed, ensure that every indication on the Clutch

Dial [4] from number "1" to the hammer mark " " can be aligned with the triangle mark on Housing

(A).(B) Set [33], respectively, and that the Clutch Dial [4] turns moderately. If any indication on the

Clutch Dial [4] cannot be aligned with the triangle mark on Housing (A).(B) Set [33], correctly remount the improperly mounted Clutch Dial [4] according to step (2). Check for proper operation of the Shift

Knob [37]. Confirm that the speed changes properly between high and low by shifting the Shift Knob

[37]. If the speed does not change properly or moderately, correctly remount the improperly mounted

Shift Knob [37] according to step (3).

5. Other precautions on reassembly

After completing reassembly, confirm that the rotating direction of the Drill Chuck 13VLRS-N [2] matches the position of the Pushing Button [35]. When the Pushing Button [35] is pressed from the (R) side, the rotating direction of the Drill Chuck 13VLRS-N [2] should be clockwise as viewed from behind. Switch the

Models DV 18DCL2, DV 18DVC2, DV 14DCL2 or DV 14DVC2 on and off by using the battery. Use a 12 mm dia. test bar to confirm that runout of the Drill Chuck 13VLRS-N [2] is 0.8 mm or less at the position 110 mm away from the tip of the chuck.
