• Bolt. The proper fastening torque will differ according to the diameter of the bolt,
the torque coefficient, the bolt length, and the class of bolt.
• The use of a universal joint or an extension bar (both available separately) will
reduce the fastening force of the impact wrench somewhat. Compensate by
fastening for a longer period of time.
• The manner of holding the tool or the material to be fastened will affect the torque.
LOOSENING FASTENERS
• With the proper impact socket securely mounted to the cordless impact wrench,
slide the impact socket on to the bolt head.
• Verify that the rotational direction is “reverse”.
• Hold the tool securely with both hands and squeeze the trigger switch. The tool will
start to impact immediately.
• Once the fastener has “broken loose” it will start to unthread. Be careful that you
do not allow a fastener to spin freely once it is no longer engaged with the other
threaded part, as it may be thrown out of the socket.

LOW-VOLTAGE CUT-OUT
The battery pack used on this tool is fitted with a low-voltage cut-out feature within
the circuitry. The low-voltage cut-out feature operates when the voltage drops below
a pre-set value. This feature automatically stops the tool from operating. When this
condition occurs you will need to either insert another battery pack into the tool or
recharge the existing battery pack.
TIGHTENING FASTENERS
Before starting your job, always perform a test operation to determine the proper
fastening time for your bolt or nut.
• Install the socket on the anvil. Then, set the forward & reverse lever for the suitable
setting (forward or reverse).
• Hold the tool firmly and place the socket in line with the bolt or nut.
• Press the trigger switch to turn on the impact wrench. The variable speed trigger
switch delivers higher speed with increased trigger pressure and lower speed with
decreased trigger pressure.
• Fasten the bolt or nut to the proper torque.
• To turn the impact wrench off, release the trigger switch.
• After fastening, always check the torque with a torque wrench.
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.
The fastening torque is affected by a wide variety of factors, including the following:
• Socket. Failure to use the correct size socket will cause a reduction in the fastening
torque. A worn socket (wear on the hex end or square end) will cause a reduction in
the fastening torque.
NOTE:
• The impact wrench will not restart until the battery pack has cooled.
.
• Do not force cool the pack in any way. Do not place in refrigerator
or freezer. To reduce the temperature of the cells remove the
battery pack from the tool and place the battery pack in a free air
environment, out of direct sunlight or any other heat source.
NOTE:
NOTE:
Attempting to restart the tool without either recharging
the battery or installing another battery (with charge) will lead to
tool restarting and then stopping again, after only a few seconds of
operation.
NOTE:
The torque that is required to loosen a fastener averages 75% to 80%
of the tightening torque, depending on the condition of the contacting
surfaces. However, if rust or corrosion causes seizing, more torque may
be required.
• Hold the tool straight along the axis of the bolt or nut.
• Excessive fastening torque may damage the bolt/nut or socket.
