Tool operation
Installing Or Removing Socket
Always be sure that the machine is switched off and the battery pack
is removed before installing or removing the socket.
Caution
1. To install the socket, push the socket into the driving spindle as far as it
will go. (See Fig.1)
2. To remove the socket, simply pull the socket from the driving spindle.
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. For reversing the machine, (See Fig. 2) Use the forward / reverse knob
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 com-
plete 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 according 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.
