lnstalling Or Removing Socket
Always be sure that the machine is switched off and the battery pack is removed befare
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.4)
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. Far reversing the machine, (See Fig.5) use the forward / reverse rod on the drive unit. The
directions of the rotation are also shown on the face of the bar.
5. Alwavs check the direction of rotation befare operation.
6. Use the farward / reverse rod only after the machine come to a complete stop. Changing the
direction of rotation befare 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 far the nut that you wish to use.
• Hold the machine pointed straight at the nut. lf you tighten the nut far a time longer than it
needs, the nut or the point of the driver socket may be overstressed, stripped, damaged,
etc. Befare starting your job, always perform a test operation to determine the proper
tightening time far your screw. When tightening a standard nut in a steel plate, the proper
tightening torque can be obtained in an extremely short time.
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.
