Switch action (Fig. 5)

CAUTION:

Before plugging in the tool, always check to see the

switch trigger actuates properly and returns to the "OFF"

position when released .

To start the tool, simply pull the trigger. Tool speed is

increased by increasing pressure on the trigger. Release

the trigger to stop. For continuous operation, pull the trig-

ger and then push in the lock button. To stop the tool from

the locked position, pull the trigger fully, then release it. A

speed control screw is provided so that maximum tool

speed can be limited (variable). Turn the speed control

screw clockwise for higher speed, and counterclockwise

for lower speed.

Reversing switch action (Fig. 6)

CAUTION:

• Always check the direction of rotation before drilling.

• Use the reversing switch only after the tool comes to a

complete stop. Changing the direction of rotation

before the tool stop may damage the tool.

This tool has a reversing switch to change the direction of

rotation. Move the reversing switch lever to the "FWD"

position for clockwise rotation or the "REV" position for

counterclockwise rotation.

Speed change (Fig. 7)

To change the tool speed, turn the speed change knob

so that the reference arrow on the tool body points to the

desired speed indication.

CAUTION:

Turn the speed change knob only after the tool comes to

a complete stop.

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 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 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.

• 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

unplugged before carrying out any work on the tool.

To maintain product safety and reliability, repairs, mainte-

nance or adjustment should be carried out by a Makita

Authorized Service Center.
