4-1. Selling Point Descriptions
4-1-1. Choice of three operation modes for flexibility
This Model can be easily switched between three modes, screwdriving, drilling and impact drilling, simply by
turning the cap dial. To use it as a screwdriver, set the cap to any position between 1 and 22, depending on the
types of screws and the material to be fastened. The clutch is then coupled to adjust the tightening force among
the corresponding 22 different levels.
In order to fasten large wood screws and drill metals, woods and plastics, align the cap drill mark
" " with the triangle mark on the main body. The clutch is then directly coupled to provide the maximum
power output. Drilling into very hard materials such as brick and concrete block can be efficiently carried out by
aligning the cap impact mark " " with the triangle mark on the main body. (See Fig. 1.)

4-1-2. Variable-speed switch with brake (and electronic feedback mechanism)
The brake immediately brings the operation to a stop with a simple release of the switch lever, making the unit
most convenient for continuous screw tightening and drilling.
The variable-speed switch is able to freely control the rotation speed depending on how far the switch lever is
pulled, between 0 and 350/min. for the low speed mode and between 0 and 1,250 min. for the high speed mode.
This facilitates positional adjustment, for instance, when tightening a wood screw.
The feedback mechanism ensures a greater torque even in the lower end of the variable-speed range.
