In the event that the above methods do not result in a cocked chuck,
please refer to the Chuck Troubleshooting section of this document for
possible resolutions.
Bit Assembly Installation
Once a carving function has been selected from the display menu, the
CarveWright machine will move the cutting head to the center of the
machine and prompt for the user to insert the required bit.
• WARNING: Use caution to avoid being cut by the razor sharp
carbide cutting edges of the router bits. When touching a bit
make sure to only grab non-sharpened surfaces. If this is not
possible please use a cloth or glove to grab the bit.
To insert a bit into an empty chuck: lift up on the front safety cover, move
the z-truck to the center and top of its travel, and cock the quick release
chuck. Without touching the z-truck or QC, press the bit assembly up until
a slight snap is felt. Press down on the spring loaded cap to assure that
the spring loaded cap is completely down and twist the spring loaded cap
in the clockwise direction to assure that it is firmly seated
It is critically important that the bit assembly be properly assembled.
Severe damage to the chuck, bit, project and even the machine can occur
if the bit is not properly installed. Check the following to assure that the bit
is properly installed before proceeding with a cut:
• Assure that a snap is heard when the bit is loaded into the cocked
chuck
• Assure that no play can be felt at the tip of the bit once assembled
into the chuck
• Assure that the bit is secure by pulling down on the bit
If any one of these three conditions is not met do NOT proceed with
cutting. STOP, diagnose, and address problems until each condition is
met. Please see the Chuck Troubleshooting section for a comprehensive
discussion of how to diagnose and fix issues with the quick change chuck.
Bit Assembly Removal
The process for removing a bit assembly is almost identical to the one
used to cock the chuck. To remove a bit assembly, place a thumb in the
z-truck grip ridge and the middle and index fingers of the same hand
under the chuck release flange on the spring loaded cap. Next place the
middle and index fingers of the other hand around the shank of the bit.
Pull up on the chuck release flange. As the cap moves upward it will
rotate slightly in the counter-clockwise direction relative to the tapered
body. The bit assembly should drop out once the cap has been raised
sufficiently.
