OPERATING INSTRUCTIONS
5. Installing and Removing Socket
a. Place the direction-of-rotation-selector (C) in
the center (lock) position.
b. To install a 1/2 in. socket (not included), simply
push it 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.
6. Tighten Fasteners with the Impact Wrench
WARNING
• Battery tools are always in operating condition. Therefore, the direction-of-rotation selector (C)
should always be locked when not in use or carrying at your side.
The proper fastening torque may differ depending on the type or size of the bolt, the material of
the workpiece to be fastened, etc. Before starting your job, always perform a test operation to
determine the proper fastening time for your bolt or nut.
a. Check the direction-of-rotation selector (C) for the correct setting (forward or reverse).
b. Hold the tool rmly and place the socket over the bolt or nut.
c. Depress the variable-speed trigger switch (B) 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.
d. Fasten the bolt or nut to the proper torque.
e. To turn the impact wrench OFF, release the variable-speed trigger switch.
f. After fastening, always check the torque with a torque wrench.
NOTICE: Hold the tool straight along the axis of the bolt or nut.
NOTICE: Excessive fastening torque may damage the bolt/nut or socket.
Practice with various fasteners, noting the length of time required to reach the desired torque.
Check the tightness with a torque wrench. If the fasteners are too tight, reduce the impacting time.
If they are not tight enough, increase the impacting time.
