operation
To change the speed, switch off the tool first. Select
the "2" side 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 "2", slide the lever to the "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.

The fastening torque can be adjusted in 20 steps 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.
