When the pilot lamp flickers rapidly in red (at 0.2–
second intervals), check for and take out any
foreign objects in the charger’s battery installation
hole. If there are no foreign objects, it is probable

OPERATION
1. Installing the bit (WH18DSDL)
Always follow the following procedure to install
driver bit. (Fig. 6)
Fig. 6
(1) Pull the guide sleeve forward.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve and it returns to its origianl
position.
CAUTION
If the guide sleeve does not return to its original
position, then the bit is not installed properly.
2. Removing the bit (WH18DSDL)
Please do the opposite point on the method of
installing bit.
3. Selecting the socket matched to the bolt
(WR18DSDL)
Be sure to use a socket which is matched to the bolt
to be tightened. Using an improper socket will not
only result in insufficient tightening but also in
damage to the socket or nut.
A worn or deformed hex. or square-holed socket will
not give an adequate tightness for fitting to the nut
or anvil, consequently resulting in loss of tightening
torque.
Pay attention to wear of socket hole, and replace
before further wear has developed.
4. Installing a socket (WR18DSDL)
Select the socket to be used.
