Makita BHR240, Instruction Manual

Drilling in wood or metal (Fig. 18 & 19)

Use the optional drill chuck assembly. When installing it, 
refer to “Installing or removing the bit” described on the 
previous page.
Set the action mode changing knob so that the pointer 
points to the   symbol.

CAUTION:

• Never use “rotation with hammering” when the drill 

chuck assembly is installed on the tool. The drill chuck 
assembly may be damaged. Also, the drill chuck will 
come off when reversing the tool.

• 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 twisting force exerted on the 

tool/bit at the time of hole breakthrough. 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.

MAINTENANCE

CAUTION:

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

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

Replacing carbon brushes (Fig. 20)

Remove and check the carbon brushes regularly. 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.
Use a screwdriver to remove the brush holder caps. Take 
out the worn carbon brushes, insert the new ones and 
secure the brush holder caps. 

(Fig. 21)

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.
