(3) Installing the side handle and handle joint (Fig. 10)

The side handle and handle joint can be installed

on either side of the angle unit for right or left

handed use. To install the side handle and handle

joint, thread it into the socket on the desired side

of the angle unit and tighten it securely.

(4) Removing keyless chuck from angle unit

⅜ The keyless chuck can be removed from angle unit

in the same manner it was removed from the impact

drill; however, ALWAYS REMOVE ANGLE UNIT

FROM THE IMPACT DRILL BEFORE ATTEMPTING

TO LOOSEN KEYLESS CHUCK. This will prevent

damage of impact drills gear. Use open end wrench

provided to hold angle unit spindle before attempting

to loosen keyless chuck.

CAUTION:

If the keyless chuck cannot be removed by striking

the wrench, don’t strike the wrench forcibly and

send the impact drill to a HITACHI AUTHORIZED

SERVICE CENTER.

7. IMPACT to ROTATION changeover (Fig. 11)

The Impact Drill can be switched from IMPACT

(impact plus rotation) to ROTATION (rotation only)

by turning the change lever. When boring concrete,

stone, tile or similar hard materials, turning the

change lever to IMPACT side. The drill head impacts

against the material while continuing to rotate.

When boring metal, wood or plastic, turning the

change lever to ROTATION side. The impact drill

can be used as an ordinary electric drill.

CAUTION

⅜ Do not use the IMPACT function for the material

such as woods or metals. Such usage will not only

reduce drill efficiency, but may also damage the

drill tip.

⅜ The change lever may not turn smoothly when

changing from impact drill mode to drill mode. (Fig.

11)

In this case, operate the machine for few seconds.

The spindle shaft will then be pushed forward, and

the change lever can be moved smoothly.

8. High-speed/Low-speed changeover (Fig. 12)

Prior to changing speed, ensure that the impact drill

has come to a complete stop. To change speed,

depress the shift lock and slide in to the appropriate

direction, as indicated by the arrow in Fig. 12. The

numeral "1" engraved in the impact drill body denotes

low speed, the numeral "2" denotes high speed.

PRACTICAL HANDLING PROCEDURES

1. Switch operation

⅜ When the switch trigger is depressed, the tool

rotates. When the switch trigger is released, the tool

stops.

⅜ The rotational speed of the impact drill can be

controlled by varying the amount that the switch

trigger is pulled. Speed is low when the switch

trigger is pulled slightly and increases as the switch

trigger is pulled more.

⅜ When releasing the switch trigger, the brake will

be applied for immediate stopping.

2. When using as a Drill or an Impact Drill

(1) Pressing force of the impact drill

You cannot drill holes more quickly even if you

press the impact drill with a stronger force than

necessary. It not only damages tip of drill bit and

decreases the efficiency of operation, but also

shortens the life of the drill tip.

(2) In case of penetrating holes

Drill bits can be broken when the material being

drilled is penetrated. It is important to decrease

pressing force just before penetrating.

CAUTION

In continuous operation, conduct no-load operation

for five seconds after completing a drilling job.

(3) When a thick drill bit is used

Your arm is subjected to larger reaction force when

a thicker drill bit is used. Be careful not to be moved

by the reaction force. For this, establish a foothold,

hold the unit tightly with both hands perpendicu-

larly to the material being drilled.

NOTE

The use of the battery EB2430HA in a cold condition

(below 0 degree Centigrade) can sometimes result

in the weakened drilling torque and reduced amount

of work. This, however, is a temporary phenomenon,

and returns to normal when the battery warms up.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bit

Continued use of a worn and/or damaged drill bit

will result in reduced drilling efficiency and may

seriously overload the drill motor. Inspect the drill

bit frequently and replace it as necessary.

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. 13)

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 whthin the brush holders

NOTE:

When replacing the carbon brush with a new one,

be sure to use the Hitachi Carbon Brush Code No.

999058.

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. 15.

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. 16. Lastly, install the brush cap.

CAUTION:

Be absolutely sure to insert the nail of the carbon
