Operation - Makita TD091D Instruction Manual

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Installing or removing driver bit or socket
bit
Use only bits that has inserting portion shown in the
figure. (Fig. 5)
For European and North & South American countries,
Australia and New Zealand
Use only these type of bit. Follow the
A = 12 mm
procedure (1).
B = 9 mm
(Note) Bit-piece is not necessary.
006348
For other countries
To install these types of bits, follow the
A = 17 mm
procedure (1).
B = 14 mm
(Note) Makita bits are these types.
To install these types of bits, follow the
A = 12 mm procedure (2).
B = 9 mm (Note) Bit-piece is necessary for installing
the bit.

1. To install the bit, pull the sleeve in the direction of the
arrow and insert the bit into the sleeve as far as it will
go. Then release the sleeve to secure the bit. (Fig. 6)
2. To install the bit, pull the sleeve in the direction of the
arrow and insert the bit-piece and bit into the sleeve
as far as it will go. The bit-piece should be inserted
into the sleeve with its pointed end facing in. Then
release the sleeve to secure the bit.
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly. (Fig. 7)
NOTE:
• If the bit is not inserted deep enough into the sleeve,
the sleeve will not return to its original position and the
bit will not be secured. In this case, try re-inserting the
bit according to the instructions above.

OPERATION

The proper fastening torque may differ depending upon
the kind or size of the screw/bolt, the material of the
workpiece to be fastened, etc. The relation between
fastening torque and fastening time is shown in the
figures.

Hold the tool firmly and place the point of the driver bit in
the screw head. Apply forward pressure to the tool to the
extent that the bit will not slip off the screw and turn the
tool on to start operation. (Fig. 8)
NOTE:
• Use the proper bit for the head of the screw/bolt that
you wish to use.
• When fastening screw M8 or smaller, carefully adjust
pressure on the switch trigger so that the screw is not
damaged.
• Hold the tool pointed straight at the screw.
• If you tighten the screw for a time longer than shown in
the figures, the screw or the point of the driver bit may
be overstressed, stripped, damaged, etc. Before
starting your job, always perform a test operation to
determine the proper fastening time for your screw.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening torque
will be reduced.
2. Driver bit or socket bit
Failure to use the correct size driver bit or socket bit
will cause a reduction in the fastening torque.
