OPERATING INSTRUCTIONS
7. Installing and Removing a Socket
a. Place the direction-of-rotation selector (B) in the
center (lock) position.
b. To install a 1/2 in. socket (not included), simply
push the socket completely onto the square
anvil (A).
c. To remove the socket, pull it off.
WARNING
• Only use sockets designed for impact wrenches.
Sockets not designed for impact wrenches could
break and result in user injury. Inspect sockets
prior to use to ensure that they have no cracks or
other visible damage.
• Use protective gloves when removing the socket from the tool, or first allow it to cool. The
socket may be hot after prolonged use.
8. Tightening Fasteners with the Impact Wrench
WARNING
• Battery tools are always in operating condition. Therefore, the direction-of-rotation selector
(B) should always be locked when not in use or carrying at your side.
The proper tightening torque may differ depending on the type or size of the bolt, the material
of the workpiece to be tightened, etc. Before starting your job, always perform a test operation
to determine the proper tightening time for your bolt or nut.
a. Check the direction-of-rotation selector (B) for the correct setting (forward or reverse).
b. Select the mode as necessary according to the work piece.
c. Select the suitable speed and torque range for the application. It is advisable to perform a
trial driving on a scrap material to determine the selection.
d. Hold the tool firmly and place the socket over the bolt or nut.
e. Depress the variable-speed trigger switch (C) to turn the impact wrench on. The variable
speed trigger switch delivers higher speed with increased trigger pressure and lower
speed with decreased trigger pressure.
f. Tighten the bolt or nut to the proper torque.
g. To turn the impact wrench OFF, release the variable-speed trigger switch (C).
h. After tightening, always check the torque with a torque wrench.
NOTICE:
• Hold the tool straight along the axis of the bolt or nut.
• Excessive tightening torque may damage the bolt/nut or socket.
