Drilling operation

• 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 excep-

tions 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 perfor-

mance and shorten the service life of the tool.

• There is a tremendous 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.

• Always secure small workpieces in a vise or similar

hold-down device.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and

unplugged before carrying out any work on the tool.

Replacement of carbon brushes (Fig. 7 & 8)

Replace carbon brushes when they are worn down to the

limit mark. Both identical carbon brushes should be

replaced at the same time.

To maintain product safety and reliability, repairs, mainte-

nance or adjustment should be carried out by a Makita

Authorized Service Center.
