CORDLESS IMPACT SCREWDRIVER

Translation of the original instructions
4. For reversing the machine, (See Fig.8) use the forward / reverse rod on the drive unit. The directions of the rota-
tion are also shown on the face of the bar.
5. Always check the direction of rotation before operation.
6. Use the forward / reverse rod only after the machine come to a complete stop. Changing the direction of rotation
before the machine stops may damage the machine.
7. Hold the machine firmly and place the point of driver socket in the nut.
Apply forward pressure to the machine to the extent that the socket will not slip off the nut and turn the machine on
to start operation.
• Use the proper socket for the nut that you wish to use.
• Hold the machine pointed straight at the nut. If you tighten the nut for a time longer than it needs, the nut or the
point of the driver socket may be overstressed, stripped, damaged, etc. Before starting your job, always perform
a test operation to determine the proper tightening time for your screw. 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 machine off as soon as the impact sound is heard. When tightening nut M6 or smaller, carefully adjust
pressure on the main switch so that the nut is not damaged.
8. The tightening torque is affected by a wide variety of factors including the following. After tightening always check
the torque with a torque wrench.
• When the battery pack 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.
• For driving a bolt:
Even though the torque coefficient and the class of bolt are the same, the proper tightening torque will differ accor-
ding to the diameter of the bolt.
9. Even the diameter of the bolt are same, the proper tightening torque will differ according to the torque coefficient,
the class of the bolt and the bolt length.
10. The manner of holding the machine or the material of driving position to be tightened will affect the torque.
