They can cause rust and collated tape problems, so when you will not be using the screws for awhile, put them in the screw packing box or the like.

MAINTENANCE AND INSPECTION

1. Inspecting the driver bit

Using a broken bit or one with a worn out tip is dangerous because the bit can slip. Replace it by a new one.

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. 22)

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 HiKOKI Carbon Brush Code No.

5. Replacing carbon brushes

Take out the carbon brush by rst removing the brush cap and then hooking the protrusion of the carbon brush with a at head screw driver, etc., as shown in Fig. 24. 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 nger as illustrated in Fig. 25. 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
