Tool Operation - Bahco BCL33IW2 Betriebsanleitung

7. R emove the plug after finishing the charge.
8. The charger should be cooled at least one hour after continue charging three times.
9. Do not use generator for charging the battery pack.

8. 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 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 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.
•
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.
