MPTL144IW 3/8" 14.4V IMPACT WRENCH WITH LED LIGHT

Operating the Tool

Always be sure that the machine is switched off and the battery cartridge is removed before installing
or removing the socket.
1. To install the socket, push the socket onto the anvil as far as it will go.
2. To remove the socket, simply pull the socket from the anvil.
3. To start the tool, simply pull the trigger. Release the trigger to stop.
4. For reversing the tool, use the forward/reverse switch on the drive unit. The directions of the
rotation are also shown on the face of the switch.
5. Always check the direction of rotation before operation..
6. Use the forward/reverse switch only after the tool comes to a complete stop. Changing the
direction of rotation before the tool stops may damage the gears.
7. Hold the tool firmly in place, make sure the socket is completely over the nut. Apply forward
pressure to the tool to the extent that the socket will not slip off the nut. Pull the trigger to begin.
NOTE:
• Use the proper socket size for the nut that you intend to install or remove.
• Hold the tool pointed straight at the nut. If you tighten the nut for a time longer than it needs, the
nut or point of the driver socket may be overstressed, stripped, damaged, etc. When tightening a
standard nut in a steel plate, the proper tightening torque can be obtained in an extremely short
time (approx. 0.1-0.2 seconds).
• Turn the tool off as soon as the impact sound is heard.
• When tightening nut M6 or smaller, carefully adjust pressure on the switch trigger so that the nut
is not damaged.
8. The tightening torque is affected by a wide variety of factors including the following.
• When the battery cartridge is discharged almost completely, voltage will drop and the tightening
torque will be reduced.
• Driver bit or socket bit:
Failure to use the correct size driver bit or socket bit will cause a reduction in the tightening
torque.
• Driving a bolt:
Even though the torque coefficient and the class of bolt are the same, the proper tightening torque
will differ according to the diameter of the bolt.
9. Even if the diameter of the bolts are the same, the proper tightening torque will differ according to
the torque coefficient, the class of the bolt and the bolt length.
10. The manner in which the tool is held or the driving position of the material to be tightened will
affect the torque.
