Installing or removing driver bit or drill bit (Fig. 2)

Important:

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

cartridge is removed before installing or removing the bit.

Hold the ring and turn the sleeve counterclockwise to

open the chuck jaws. Place the bit in the chuck as far as

it will go. Hold the ring firmly and turn the sleeve clock-

wise to tighten the chuck. To remove the bit, hold the ring

and turn the sleeve counterclockwise.

Switch action (Fig. 3)

CAUTION:

Before inserting the battery cartridge into the tool, always

check to see that 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.

Reversing switch action (Fig. 4)

CAUTION:

• Always check the direction of rotation before operation.

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

complete stop. Changing the direction of rotation

before the tool stops may damage the tool.

This tool has a reversing switch to change the direction of

rotation. Slide the reversing switch to the left for clock-

wise rotation or to the right for counterclockwise rotation.

Adjusting fastening torque (Fig. 5)

The fastening torque can be adjusted in six stages by

turning the adjusting ring so that the pointer on the

adjusting ring points to a number on the tool body. The

fastening torque is minimum when the pointer points to

the number 1 and maximum when it points to the

marking. The clutch will slip at varying torque

levels when the pointer is set at the numbers 1 to 5. The

clutch is designed not to slip at the

Before actual operation, drive a trial screw into your

material or a piece of duplicate material to determine

which torque level is required for a particular application.

NOTE:

The adjusting ring cannot be locked with the pointer posi-

tioned half-way between the numbers.

Installing set plate (Fig. 6)

Always install the set plate when using battery cartridges

9100, 9102 or 9102A. Install the set plate on the tool with

the screw provided as shown in Fig. 6.

marking.

Screwdriving operation (Fig. 7)

Place the point of the driver bit in the screw head and

apply pressure to the tool. Start the tool slowly and then

increase the speed gradually. Release the trigger as

soon as the clutch cuts in.

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.

Drilling operation

First, turn the adjusting ring so that the pointer on the

adjusting ring points to the

ceed as follows.

• Drilling in wood

When drilling in wood, 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 centre-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 per-

formance 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 vice or similar

hold-down device.

MAINTENANCE

CAUTION:

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

tery cartridge is removed 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 Centre.
