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.
CAUTION:
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
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.

Hammer drilling operation
To drill in the concrete or tiles, first, turn the action mode
changing lever so that the arrow on the lever points to the
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 switch 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.
Screwdriving operation
When driving small wood screws or machine screws.
set the action mode changing lever to the
Adjust 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.

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.
