screw will be automatically carried to the driving position 
and fastened.

CAUTION:

• Always check the bit carefully for wear before driving 

operations. Replace a worn bit or poor fastening may 
result.

• Always hold the tool squarely against the driving sur-

face. Holding it at an angle may damage the screw 
heads and cause wear on the bit. This may also lead to 
poor fastening.

• Always keep the tool firmly against the driving surface 

until the driving is over. Failure to do so may cause 
insufficient fastening of screws.

• Be careful not to drive a screw onto another screw 

already fastened.

• Do not operate the tool without screws. It will damage 

the driving surface.

• If the feeder box does not work smoothly when driving 

screws, spray car wax (spray type) on the sliding sur-
faces. Never lubricate it.

Driving in corner  (Fig. 14)

This tool can be used to drive at a position 15 mm away 
from the wall as shown in the figure.

CAUTION:

• Driving at a position closer than 15 mm to the wall or 

driving with the stopper base in contact with the wall 
may damage the screw heads and cause wear on the 
bit. This may also lead to poor fastening of screws and 
malfunction of the tool.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and the bat-

tery cartridge is removed before attempting to perform 
inspection or maintenance.

Replacing carbon brushes

Replace when they wear down to the limit mark. Keep the 
carbon brushes clean and free to slip in the holders. Both 
carbon brushes should be replaced at the same time. Use 
only identical carbon brushes. 

(Fig. 15)

Loosen the thumb screws which secure the casing. Pull 
out the casing in the direction of the arrow. 

(Fig. 16)

Use a screwdriver to remove two screws then remove the 
front cover. 

(Fig. 17)

Raise the arm part of the spring and then place it in the 
recessed part of the housing with a slotted bit screwdriver 
of slender shaft or the like. 

(Fig. 18)

Use pliers to remove the carbon brush caps of the carbon 
brushes. Take out the worn carbon brushes, insert the 
new ones and replace the carbon brush caps in reverse. 

(Fig. 19)

Make sure that the carbon brush caps have fit into the 
holes in brush holders securely. 

(Fig. 20)

Reinstall the front cover and tighten two screws securely.
To maintain product SAFETY and RELIABILITY, repairs,
