Tightening bolts (Fig. 16 & 17)
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.
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 start-
ing your job, always perform a test operation to deter-
mine the proper fastening time for your screw.
CAUTION:
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.
The fastening torque is affected by a wide variety of fac-
tors 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.
Hammer drilling operation
CAUTION:
• There is tremendous and sudden twisting force exerted
on the tool/bit at the time of hole breakthrough, when
the hole becomes clogged with chips and particles, or
when striking reinforcing rods embedded in the con-
crete.
To drill in the concrete or tiles, first, turn the action mode
changing lever so that the arrow on the lever points to the
mark on the tool body. The adjusting ring can be
aligned in any torque levels for this operation.
Be sure to use a tungsten-carbide tipped bit.
Position the bit at the desired location for the hole, then
pull the trigger.
Do not force the tool. Light pressure gives best results.
Keep the tool in position and prevent it from slipping away
from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at an
idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
CAUTION:
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.
Screwdriving operation (Fig. 18)
CAUTION:
• Adjust the adjusting ring to the proper torque level for
your work.
When driving small wood screws or machine screws, set
the action mode changing lever to the
the adjusting ring to the proper torque level for your work.
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 switch trigger
as soon as the clutch cuts in.
CAUTION:
• Make sure that the driver bit is inserted straight in the
screw head, or the screw and/or bit may be damaged.
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.
NOTE:
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece.

Drilling operation
First, set the action mode changing lever so that the
pointer points to the
mark is for low speed rotation and the
high. The adjusting ring can be aligned in any torque lev-
els for this operation. Then proceed as follows.
Before operation, always make sure that the lever is cor-
rectly set to your desired mode mark and use the tool at
an appropriate speed for your work.
Then proceed as follows.
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.
