14.Using the bit holder

CAUTION

￿ Stow the bit in the specified location on the tool. If the tool is used with the bit stowed improperly, the bit may fall and cause bodily injury.

￿ Do not stow bits that are of a different length, gauge or dimension than the plus driver bit (65 mm long) included in the STANDARD ACCESSORIES.

The bit may fall and cause bodily injury.

(1) Removing the bit

Securely hold the main unit and pull out the bit by holding the tip with your thumb (Fig. 20).

(2) Installing the Bit

Install the bit with steps opposite of when removing. Insert the bit so that the right and left sides are equal, as shown in Fig. 21.

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. 22).

(2)Loosen the grip to remove the side handle.

MAINTENANCE AND INSPECTION1.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. 23)

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. 25.

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. 26. 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 Impact 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 Impact driver drill in a place in which the temperature is less than 40°C and out of reach of children.
