To change the speed, switch off the tool first. Push the speed
change lever to display "2" for high speed or "1" for low speed
but high torque. Be sure that the speed change lever is set to
the correct position before operation.
If the tool speed is coming down extremely during the
operation with display "2", push the lever to display "1"
and restart the operation.
Selecting the action mode
CAUTION:
Always set the ring correctly to
your desired mode mark. If you operate the tool
with the ring positioned halfway between the
mode marks, the tool may be damaged.
CAUTION:
When you change the position
from "
" to other modes, it may be a little dif-
ficulty to slide the action mode changing ring. In
this case, switch on and run the tool for a second
at the "
" position, then stop the tool and slide
the ring to your desired position.
This tool has three action modes.
•
Drilling mode (rotation only)
•
Hammer drilling mode (rotation with
hammering)
•
Screwdriving mode (rotation with clutch)
Select one mode suitable for your work. Turn the
action mode changing ring and align the mark that you
selected with the arrow on the tool body.

The fastening torque can be adjusted in 20 levels by turning the adjusting ring. Align the graduations with the arrow
on the tool body. You can get the minimum fastening torque at 1 and maximum torque at 20.
Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which
torque level is required for a particular application. The following shows the rough guide of the relationship between
the screw size and graduation.
