NOTE:

• Make sure that the driver bit is inserted straight in the 

screw head, or the screw and/or bit may be damaged.

• When driving wood screws, predrill pilot holes to make 

driving easier and to prevent splitting of the workpiece. 
See the chart.

NOTE:

• If the tool is operated continuously until the battery 

cartridge has discharged, allow the tool to rest for 
15 minutes before proceeding with a fresh battery.

Drilling operation

First, slide the action mode change lever to the position of 

 symbol.

Drilling in wood

When drilling in wood, the best results are obtained with 
wood drills equipped with a guide screw. The guide screw 
makes drilling easier by pulling the bit into the workpiece.

Drilling in metal

To prevent the bit from slipping when starting a hole, 
make an indentation with a center-punch and hammer at 
the point to be drilled. Place the point of the bit in the 
indentation and start drilling.
Use a cutting lubricant when drilling metals. The 
exceptions are iron and brass which should be drilled dry.

CAUTION:

• Pressing excessively on the tool will not speed up the 

drilling. In fact, this excessive pressure will only serve 
to damage the tip of your bit, decrease the tool 
performance and shorten the service life of the tool.

• There is a tremendous force exerted on the tool/bit at 

the time of hole break through. Hold the tool firmly and 
exert care when the bit begins to break through the 
workpiece.

• A stuck bit can be removed simply by setting the 

reversing switch to reverse rotation in order to back 
out. However, the tool may back out abruptly if you do 
not hold it firmly.

• Always secure small workpieces in a vise or similar 

hold-down device.

• If the tool is operated continuously until the battery 

cartridge has discharged, allow the tool to rest for 
15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:

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

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

• Never use gasoline, benzine, thinner, alcohol or the 

like. Discoloration, deformation or cracks may result.

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. 14)

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

(Fig. 15)

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. 16)

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

(Fig. 17)

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

(Fig. 18)

Reinstall the rear cover and tighten two screws securely.
To maintain product SAFETY and RELIABILITY, repairs, 
any other maintenance or adjustment should be 
performed by Makita Authorized Service Centers, always 
using Makita replacement parts.
