USER MANUAL DS 18DL2 HITACHI

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.

Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet.

Never modify the plug in any way.

Do not use any adapter plugs with earthed (grounded) power tools.

Unmodified plugs and matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts.

Damaged or entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces the risk of electric shock.

f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.

Use of an RCD reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication.

A moment of inattention while operating power tools may result in serious personal injury.

b) Use personal protective equipment. Always wear eye protection.

Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.

Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on.

A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times.

This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts.

Loose clothes, jewellery or long hair can be caught in moving parts.

g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used.

Use of dust collection can reduce dust related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct power tool for your application.

The correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off.

Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.

Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation.

If damaged, have the power tool repaired before use.

Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed.

Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Battery tool use and care

a) Recharge only with the charger specified by the manufacturer.

A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

b) Use power tools only with specifically designated battery packs.

Use of any other battery packs may create a risk of injury and fire.

c) When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another.

Shorting the battery terminals together may cause burns or a fire.

d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

6) Service

a) Have your power tool serviced by a qualified repair person using only identical replacement parts.

This will ensure that the safety of the power tool is maintained.

CAUTION:

Do not use the electrical cord if damaged. Have it repaired immediately.

When charging the battery from a DC 12V in-car power source (UC18YMRL)

Secure the battery charger in place in the car.

Use the strap supplied with the battery charger to fasten the battery charger in place and prevent it from moving inadvertently. (See Fig. 25)

CAUTION:

Do not place the battery charger or battery under the driver's seat. Secure the battery charger in place to prevent it from moving inadvertently as this may lead to an accident.

Fig. 25

Insert the cigarette lighter connecting plug into the cigarette lighter socket.

If the plug is loose and falls out of the cigarette lighter socket, repair the socket. As the socket may be faulty, you are recommended to contact your local car dealer. Continued use of the socket may result in an accident due to overheating. (Fig. 3)

2. Insert the battery into the charger.

Firmly insert the battery into the charger till it contacts the bottom of the charger and checking the polarities as shown in Fig. 3.

CAUTION:

If the batteries are inserted in the reverse direction, not only recharging will become impossible, but it may also cause problems in the charger such as a deformed recharging terminal.

3. Charging

When inserting a battery in the charger, charging will commence and the pilot lamp will light continuously in red.

When the battery becomes fully recharged, the pilot lamp will blink in red. (At 1-second intervals) (See Table 1)

(1) Pilot lamp indication

The indications of the pilot lamp will be as shown in Table 1, according to the condition of the charger or the rechargeable battery.

Table 1

Indications of the pilot lamp
The pilot lamp lights or blinks in red.	Before charging	Blinks	Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds)
	While charging	Lights	Lights continuously
	Charging complete	Blinks	Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds)
	Charging impossible	Flickers	Lights for 0.1 seconds. Does not light for 0.1 seconds. (off for 0.1 seconds)	Malfunction in the battery or the charger
The pilot lamp lights or blinks in green.	Overheat standby	Lights	Lights continuously	Battery overheated. Unable to charge. (Charging will commence when battery cools)
	Charging with in-car power source impossible (UC18YMRL)	Blinks	Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds)	Malfunction of the car battery

NOTE: When standby for cooling battery, UC18YMRL / UC18YRL cools the overheated battery by cooling fan. (However, the cooling fan does not function when charging the battery with a DC 12V in-car power source.)

(2) Regarding the temperatures of the rechargeable battery

The temperatures for rechargeable batteries are as shown in Table 2, and batteries that have become hot should be cooled for a while before being recharged.

Table 2 Recharging ranges of batteries

Rechargeable batteries	Temperatures at which the battery can be recharged
BCL1430, BCL1440, EBM1830, BCL1840	0°C – 50°C

(3) Regarding recharging time

Depending on the combination of the charger and batteries, the charging time will become as shown in Table 3.

Table 3 Charging time (At 20^)

(AC power supply / DC 12V (in-car) power supply)

Charger Battery	UC18YMRL UC	18YRL
BCL1430, EBM1830	Approx. 45 / 120 min.	Approx. 45 min.
BCL1440, BCL1840	Approx. 60 / 160 min.	Approx. 60 min.

NOTE:

The recharging time may vary according to the ambient temperature and power source voltage.

Especially, using a DC 12V in-car power source may require longer recharging time at high temperatures.

CAUTION:

When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging.

1. Disconnect the charger's power cord from the receptacle or cigarette lighter socket

2. Hold the charger firmly and pull out the battery NOTE:

Be sure to pull out the battery from the charger after use, and then keep it.

Regarding electric discharge in case of new batteries, etc.

As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. 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 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 up green. In such a case, first let the battery cool, then start charging.
- When the pilot lamp flickers in red (at 0.2-seconds 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 confirm that the battery being charged with UC18YMRL / UC18YRL 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.
Check the voltage of the in-car power source when the pilot lamp flickers in green (every 0.2 seconds) continuously. (UC18YMRL)

If the voltage is 12V or lower, it indicates that the car battery has weakened and cannot be charged.

If the pilot lamp does not blink in red (every second) even though the charger cord or cigarette lighter connecting plug is connected to the power, it indicates that the protection circuit of the charger may be activated.

Remove the cord or plug from the power and then connect it again after 30 seconds or so. If this does not cause the pilot lamp to blink in red (every second), please take the charger to the Hitachi Authorized Service Center.

PRIOR TO OPERATION

1. Setting up and checking the work environment

Check if the work environment is suitable by following the precautions.

HOW TO USE

1. Confirm the clutch dial position (see Figs. 4, 6)

The tightening torque of this unit can be adjusted according to the clutch dial position, at which the clutch dial is set.

(1) When using this unit as a screwdriver, line up the one of the numbers "1, 3, 5 ... 22" on the clutch dial, or the dots, with the triangle mark on the outer body.
(2) When using this unit as a drill, align the clutch dial drill mark "A" with the triangle mark on the outer body.
(3) When using this unit as an impact drill, align the clutch dial hammer mark "T with the triangle mark on the outer body.

CAUTION:

The clutch dial cannot be set between the numerals "1, 3, 5 ... 22" or the dots.
Do not use with the clutch dial numeral between "22" and the line at the middle of the drill mark. Doing so may cause damage. (See Figs. 5, 7)

2. Tightening torque adjustment

(1) Tightening torque

Tightening torque should correspond in its intensity to the screw diameter. When too strong torque is used, the screw head may be broken or be injured. Be sure to adjust the clutch dial position according to the screw diameter.

(2) Tightening torque indication

The tightening torque differs depending on the type of screw and the material being tightened.

The unit indicates the tightening torque with the numbers "1, 3, 5 ... 22" on the clutch dial, and the dots. The tightening torque at position "1" is the weakest and the torque is strongest at the highest number. (See Figs. 4, 6)

(3) Adjusting the tightening torque

Rotate the clutch dial and line up the numbers "1, 3, 5, ... 22" on the clutch dial, or the dots, with the triangle mark on the outer body. Adjust the clutch dial in the weak or the strong torque direction according to the torque you need.

CAUTION:

The motor rotation may be locked to cease while the unit is used as drill. While operating the driver drill, take care not to lock the motor.
Too long hammering may cause the screw broken due to excessive tightening.

3. Rotation to Impact changeover (See Fig. 6)

The "Rotation (Rotation only)" and "Impact (Impact + Rotation)" can be switched by aligning the drill mark "..." or the hammer mark "T with the triangle mark on the outer body.

To make holes in the metal, wood or plastic, switch to "Rotation (Rotation only)".
To make holes in bricks or concrete blocks, switch to "Impact (Impact + Rotation)".

CAUTION:

If an operation which is normally performed at the "Rotation" setting is performed at "Impact" setting, the effect of making holes does not only increase but it may also damage the bit or other parts.

4. Change rotation speed

Operate the shift knob to change the rotational speed. Move the shift knob in the direction of the arrow (see Figs. 8 and 9).

When the shift knob is set to "LOW", the drill rotates at a low speed. When set to "HIGH", the drill rotates at a high speed.

CAUTION:

• When changing the rotational speed with the shift knob, confirm that the switch is off.
  Changing the speed while the motor is rotating will damage the gears.
  When setting the shift knob to "HIGH" (high speed) and the position of the clutch dial is "17" or "22", it may happen that the clutch is not engaged and that the motor is locked. In such a case, please set the shift knob to "LOW" (low speed).
  If the motor is locked, immediately turn the power off. If the motor is locked for a while, the motor or battery may be burnt.

Be sure to turn the shift knob.

5. The scope and suggestions for uses

	Metal		——	For drilling with a metal working drill bit.

CAUTION:

The selection examples shown in Table 5 should be considered as general standard. As different types of tightening screws and different materials to be tightened are used in actual works proper adjustments are naturally necessary.

When using the driver drill with a machine screw at HIGH (high speed), a screw may damage or a bit may loose due to the tightening torque is too strong. Use the driver drill at LOW (low speed) when using a machine screw.

NOTE:

The use of the battery in a cold condition (below 0 degree Centigrade) can sometimes result in the weakened tightening torque and reduced amount of work. This, however, is a temporary phenomenon, and returns to normal when the battery warms up.

7. 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. Injury may result if you carry the equipment suspended from the waist belt with sharp tipped components such as drill bit attached.

(c) Install the hook and spring on the other side and securely fasten with screw. (Fig. 13)

NOTE:

Pay attention to the spring orientation. Install the spring with larger diameter away from you. (Fig. 13)

(3) Using the bit holder (Hook with bit holder)

Installing the bit

Slide the bit from the side, 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. 14)

CAUTION:

Only Hitachi STANDARD ACCESSORIES phillips bit (No. 2 × 65L ; Code No. 983006) may be used. Do not use other bits since they may come loose.

8. How to use the LED 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. 15)

9. Mounting and dismounting of the bit

(1) Mounting the bit

Loosen the sleeve by turning it toward the left (in the counterclockwise direction as viewed from the front) to open the clip on the keyless chuck. After inserting a driver bit, etc., into the keyless drill chuck, and tighten the sleeve by turning it toward the right (in the clockwise direction as viewed from the front). (See Fig. 16)

If the sleeve becomes loose during operation, tighten it further.

The tightening force becomes stronger when the sleeve is tightened additionally.

(2) Dismounting the bit

Loosen the sleeve by turning it toward the left (in the counterclockwise direction as viewed from the front), and then take out the bit ect. (See Fig. 16)

NOTE:

If the sleeve is tightened in a state where the clip of the keyless chuck is opened to a maximum limit, a click noise may occur. This is the noise that occurs when the loosening of the keyless chuck is prevented and is not a malfunction.

CAUTION:

When it is no longer possible to loosen the sleeve, use a vise or similar instrument to secure the bit. Set the clutch mode between 1 and 11 and then turn the sleeve to the loose side (left side) while operating the clutch. It should be easy now to loosen the sleeve.

10. Automatic spindle-lock mechanism

This unit has automatic spindle-lock mechanism for quick bit changes.

11. Confirm that the battery is mounted correctly

12. 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. 17) (The L and marks are provided on the selector button.)

13. 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.

14. For drilling into brick

Excessive pressing force never increases drilling speed. It will not only damage the drill tip or reduce working efficiency, but could also shorten the service life of drill bit. Operate the impact driver drill within 10-15 kg pressing force while drilling into brick.

15. Installing / Removing the side handle

CAUTION

Firmly install the side handle. If loose, the side handle may gyrate or fall out and cause bodily injury.

(1) Install the side handle so that the protrusions on the main unit and grooves on the side handle interlock. Tighten the grip after checking that the side handle is not riding on the slip prevention protrusion (Fig. 20).
(2) Loosen the grip to remove the side handle.

OPERATIONAL CAUTIONS

Resting the unit after continuous work

After use for continuous tightening wood screw works, 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.

MAINTENANCE AND INSPECTION

1. Inspecting the tool

Since use of as dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace the tool as soon as abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3. Maintenance of the motor

The motor unit winding is the very "heart" of the power tool.
Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

4. Inspecting the carbon brushes (Fig. 21)

The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the "wear limit". In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

NOTE:

When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 999054.

5. Replacing carbon brushes

Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a flat head screw driver, etc., as shown in Fig. 23.
When installing the carbon brush, choose the direction so that the nail of the carbon brush agrees with the contact portion outside the brush tube. Then push it in with a finger as illustrated in Fig. 24. Lastly, install the brush cap.

CAUTION:

Be absolutely sure to insert the nail of the carbon brush into the contact portion outside the brush tube. (You can insert whichever one of the two nails provided).
Caution must be exercised since any error in this operation can result in the deformed nail of the carbon brush and may cause motor trouble at an early stage.

6. Cleaning on the outside

When the driver drill is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.

7. Storage

Store the driver drill in a place in which the temperature is less than 40^ and out of reach of children.

NOTE:

Make sure that the battery is fully charged when stored for a long period (3 months or more). The battery with smaller capacity may not be able to be charged when used, if stored for a long period.
