Bit Adapter Assembly
The CompuCarve utilizes a patented quick release chuck system to make
changing bits fast and easy. To use this system the bits must first be
installed into the bit adapters.
For 1/2" shank bits, insert threaded bit adapter into the chuck assembly
and then insert bit into threaded collet (See Figure 20) and tighten the
collet with a wrench. Position the bit in the adapter as shown in Figure 22.
Verify that the collet is also securely tightened.
For 1/4" steel shank bits: Remove the two setscrews from the adapter
body and de-grease both the setscrews and threaded holes. This can be
done using rubbing alcohol or a product such as WD40. Thoroughly dry
the parts. Apply a drop of permanent thread cement on each setscrew to
prevent them from loosening and start the treads. Insert the bit into the bit
adapter and tighten the setscrews with supplied Allen wrench (See Figure
21). Position the bit in the adapter as shown in Figure 22 and always
make sure the setscrews are tight.
For 1/4" carbide shank bits: Carbide bits include the 1/16" carving and
1/8" cutting bits and can be identified by the two small flats on the bit
shank. Remove the two setscrews from the adapter body and de-grease
both the setscrews and threaded holes. This can be done using rubbing
alcohol or a product such as WD40. Thoroughly dry the parts. Apply a
drop of permanent thread cement on each setscrew to prevent them from
loosening and start the treads. Insert the bit into the bit adapter and
position the bit so that the setscrews align to the flats. Tighten setscrews
with supplied Allen wrench and always make sure the setscrews are tight.
WARNING: Failure to correctly install the bit in the adapter
can result in injury, damage to the machine, or damage to the
workpiece. This is especially true if the permanent thread
cement on the 1/4" adapter setscrews is omitted.
