(4)Construction of replaceable carbon brushes
The carbon brush can be easily removed from the motor with a flat-blade screwdriver as shown in Fig. 2 and
can also be easily and securely mounted to the motor by hanging the claw of the carbon brush on the
connecting portion at the outside of the brush tube.

(5) Safe handle shape
Compared with the previous WH 12DC, the housing of the Model WH 12DH produces no clearance caused by
vibration because grips (R) and (F) (made of rubber) are provided at the juncture of the handle and the
housing is secured with two screws at the center of the handle to prevent the operator's hand from being
pinched. Furthermore, the rear portion of the housing is shaped upward not to interfere with the base of the
operator's thumb.
(6) 9.6 V Battery is also available.
As the 9.6 V battery (EB 9S type) is popular in the market, it is a strong selling point that both the Models WH
12DH and WR 12DH can also use this battery. The following table shows that the tightening torque is a little
lower because of a lower voltage, but there is little harm in operation.
