1.
To install the bit, pull the retainer in the direction of the arrow and insert the bit into the retainer as far as
it will go. Then release the retainer to secure the bit.
(View Fig.1)
2.
To remove the bit, pull the retainer in the direction of the arrow and pull the bit out firmly.
Note: If the bit does not insert deeply enough into the retainer, the retainer will not return to its original
position and the bit will not be secured. In this case, try to insert the bit according to the instructions
above.
3.
For reversing the machine,
(View Fig.2)
use the forward/ reverse rod on the drive unit. The directions of
the rotation are also shown on the face of the bar.
4.
Always check the direction of rotation before operation.
5.
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.
6.
Hold the machine firmly and place the point of driver bit in the screw head. Apply forward pressure to the
machine to the extent that the bit will not slip off the screw and turn the machine on to start operation.
•
Use the proper bit 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.
•
When the battery pack is discharged almost completely, voltage will drop and the tightening torque
will be reduced.
•
When the battery pack is discharged almost completely, voltage will drop and the tightening torque
will be reduced.
•
For 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.
7.
The manner of holding the machine or the material of driving position to be tightened will affect the torque.
Operating the machine at low speed will cause a reduction in the tightening torque.
CAUTION
TOOL OPERATION
INSTALLING OR REMOVING BIT (IMPACT DRIVER)
