Maintenance - Makita DTS130 Instruction Manual

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 fas-
tening 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.
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 differs according to the
increase in the tool hotness.
• When driving wood screws, predrill pilot holes
with diameter smaller than the wood screws to
make driving easier and to prevent splitting of
the workpiece.
• The diameter of wood screws that are within
the tool capacity is not always the same and
depends on the kind of material to be driven on.
Make trial driving with several screws before
actual operation.
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.
3. Bolt
• Even though the torque coefficient and the class
of bolt are the same, the proper fastening torque
will differ according to the diameter of bolt.
• Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class
of bolt and the bolt length.
4. The manner of holding the tool or the material
of driving position to be fastened will affect the
torque.
5. Operating the tool at low speed will cause a reduc-
tion in the fastening torque.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before attempt-
ing to perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
