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
reduction in the fastening torque.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
Replacing carbon brushes
006258
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove two screws then remove
the rear cover.
006799
Raise the arm part of the spring and then place it in the
recessed part of the housing with a slotted bit
screwdriver of slender shaft or the like.
