8. TOOL OPERATION

Installing or Removing Bit (Impact Driver)
Always be sure that the machine is switched off and the battery pack is removed before installing or
removing the bit.
Fig. 1
Caution
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. As shown in (Fig. 1).
2. T o remove the bit, pull the retainer in the direction of the arrow and pull the bit out firmly. (Fig. 2).
Note: If the bit is not inserted deep enough into the retainer, the retainer will not return to its original
position and the bit will not be secured. In this case, try-inserting the bit according to the instructions
above.
3. To start the machine, simply pull the main switch. Machine speed is increase by increasing pressure
on the main switch. Release the main switch to stop.
4. F or reversing the machine, (See Fig. 3) use the forward/reverse rod on the drive unit. The directions
of the rotation 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. H old 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 screw. If you tighten the screw for a time longer than it
needs, the screw or the print of the driver bit 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 screw 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 screw M6 or smaller, carefully adjust pressure on the main switch so that the nut
is not damaged.
•
When the battery pack is discharged almost completely, voltage will drop and the tightening
torque will be reduced.
