to the "OFF" position when released.
Change the direction of rotation only when the tool
•
comes to a complete stop. Changing it before the
tool stops may damage the tool.
The switch is reversible, providing either clockwise or
counterclockwise rotation. To start the tool, simply pull the
lower part of the switch trigger for clockwise or the upper part

Move the O-ring out of the groove in the socket and
remove the pin from the socket. Fit the socket onto the
anvil of the tool so that the hole in the socket is aligned
with the hole in the anvil. Insert the pin through the hole
in the socket and anvil. Then return the O-ring to the
original position in the socket groove to retain the pin. To
remove the socket, follow the installation procedures in
reverse.
OPERATION
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.
