drugs or medication that makes you drowsy.

18. CHECK DAMAGED PARTS.

Before further use of the tool, a guard or other part that is damaged should be

carefully checked to determine that it will operate properly and perform its

intended function. Check for alignment of moving parts, binding of moving

parts, breakage of parts, mounting, and any other conditions that may affect

its operation. A guard or other part that is damaged should be properly

repaired or replaced by an authorized service center unless otherwise indi-

cated elsewhere in this Instruction Manual.

IMPORTANT SAFETY INSTRUCTIONS

FOR USE OF THE CORDLESS IMPACT DRIVER

WARNING: Death or serious bodily injury could result from improper or

unsafe use of the cordless impact driver. To avoid these risks,

follow these basic safety instructions:

1. Never use this driver handle for any application other than those in this manual.

2. Never place hands or other body parts near the drill bit or chuck during operation.

Hold the impact driver by its handle only.

3. When working in high places, always make sure that there is no one below before

starting to work.

4. Always wear eye and ear protection when you work.

5. Always install the driver bit securely. A loose bit is dangerous because it can

come loose while you are working.

6. Always use the driver bit that matches the screw size.

7. Always have the screw you are screwing in and this impact driver in a straight

line. Working with this impact driver at an angle to the screw can damage the

screw head and will not give the prescribed tightening torque.

8. Be careful that foreign matters do not block the holes located on both sides of the

handle. Also do not close the holes with a tape. The holes act an important role.

IMPORTANT SAFETY INSTRUC-

TIONS FOR BATTERY CHARGER

1. This manual contains important safety and operating instructions for battery

charger Model UC 12Y.

2. Before using battery charger, read all instructions and cautionary markings on (1)

battery charger, (2) battery, and (3) product using battery.

3. To reduce risk of injury, charge HITACHI rechargeable batteries type EB7, EB9,

EB12, EB2, B-2, B-3 or B-4. Other type of batteries may burst causing personal

injury and damage.

4. Do not expose battery charger to rain or snow.

5. Use of an attachment not recommended or sold by the battery charger manufac-

turer may result in a risk of fire, electric shock, or injury to persons.

6. To reduce risk of damage to electric plug and cord, pull by plug when disconnect-

ing battery charger.

7. Make sure cord is located so that it will not be stepped on, tripped over, or

otherwise subjected to damage or stress.

8. An extension cord should not be used unless absolutely necessary. Use of

improper extension cord could result in a risk of fire and electric shock.

If extension cord must be used make sure:

a. That blades of extension cord are the same number, size, and shape as

those of plug on battery charger:

b. That extension cord is properly wired and in good electrical condition; and

c. That wire size is large enough for AC ampere rating of battery charger as

specified in Table 1.

Table 1

RECOMMENDED MINIMUM AWG SIZE FOR

EXTENSION CORDS FOR BATTERY CHARGERS

AC Input Rating Amperes* AWG Size of Cord

Equal to or but less Length of Cord, Feet (Meter)

greater than than 25 (7.5) 50 (15) 100 (30) 150 (45)

0 2 18 18 18 16

2 3 18 18 16 14

3 4 18 18 16 14

* If the input rating of a battery charger is given in watts rather than in amperes,

the corresponding ampere rating is to be determined by dividing the wattage

rating by the voltage rating-for example:

9. Do not operate battery charger with damaged cord or plug-replace them

immediately.

10. Do not operate battery charger if it has received a sharp blow, been dropped,

or otherwise damaged in any way; take it to a qualified serviceman.

11. Do not disassemble battery charger; take it to a qualified serviceman when

service or repair is required. Incorrect reassembly may result in a risk of electric

shock or fire.

12. To reduce risk of electric shock, unplug charger from receptacle before

attempting any maintenance or cleaning. Removing the battery will not reduce

this risk.
