Changing the tool (see figure A)
- Turn the drive unit all the way up using the crank handle (4).
- Ensure that the application tools are free of grease.
- Insert the pilot pin (26) into the annular cutter (27) (TCT and HSS annular cutters require different diameters of pilot pin).
- Insert the annular cutter with the pilot pin into the annular cutter adapter (22) and tighten the screws using the hex key (6 mm) (25).
Where possible, you should use an annular cutter with a Weldon shank. - Insert the annular cutter adapter into the tool holder (12).
- Connect the coolant hose (37) with the connector on the annular cutter adapter.
Tools with Morse taper MT2:
- Insert the tool directly into the tool holder (12).
Tools with Morse taper MT1:
- Insert the tool into the reduction sleeve (MT2/MT1) (30).
- Insert the reduction sleeve (with the tool inserted) into the tool holder (12).
Tools with cylindrical shank:
- Screw the keyed chuck (32) onto the taper mandrel (33) and insert the tool.
- Insert the taper mandrel (with the keyed chuck screwed in) into the tool holder (12).
- Make sure that the tool clicks securely into place.
- Do not use force to insert the Morse taper/taper mandrel. Excessive force could damage the tool holder and the inserted tool.
Use the correct screw tap adapter (23) for screw tapping.
- Insert the screw tap (24) into the adapter (23).
- With the screw tap (24) inserted, insert the adapter (23) into the annular cutter adapter (22) and tighten it using the hex key (6 mm) (25).
- Insert the annular cutter adapter (22) into the tool holder (12).
- Place the MT2 drill drift (34) in the opening (13) so that the bevelled edge faces down.
If the drill drift (34) will not go through the drive spindle, turn the application tool slightly. - Using a hammer, push the drill drift (34) towards the tool and remove the application tool from the tool holder.
