and bit. To check, simply insert a finger into the tapered body of the
chuck from below with no bit present and move the finger back and
forth checking for looseness. If looseness is detected in the spindle
please contact CarveWright support to diagnose the problem.
• Remove Dust: The CarveWright quick release chuck is designed to
tolerate a considerable amount of dust. But to ensure proper operation
it should be kept free of dust and debris as much as possible.
Regularly blow out any dust from the recesses and the taper of the
chuck. Always make sure to use low-pressure air (<80 psi) as high-
pressure air can damage adjacent electronic components.
In some cases dust may be necessary to clean the chuck with a
cleaning solution. We recommend that WD40 be used to clean the
chuck. First lay out a rag or paper over the belt trays so as not to drip
the WD40 onto the machine. Be sure to wear safety glasses as the
WD40 can be an eye irritant. Use the straw nozzle to spray the WD40
up into the chuck. Work the chuck by actuating the spring loaded cap
many times. If dust is limiting motion you will be able to feel it loosen as
you work the cap. Spray again and continue to work the cap. Once the
mechanism is working smoothly dry it with a rag and compressed air.
WD40 is a degreaser so please lubricate the chuck as described below
to prevent rust.
Dust can also become attached and compacted on the mating tapered
surfaces because it tend to stick to the light oil needed to keep it
lubricated and rust free. Keep these surfaces free of dust by cleaning
them regularly.
• Remove Pitch: Pitch buildup can become a problem if left unchecked.
Periodically remove pitch from bits, bit adapters and the internal surface
of the tapered body using mineral spirits.
• Lubricate: It is very important that the quick release chuck is always
kept properly lubricated. Keeping a thin film of oil on the chuck and bit
adapters helps to deter rust, provide lubrication, and transfer heat
between the bit adapter and the chuck assembly during heavy use.
Periodically clean out dust from the chuck. Once cleaned, re-lubricate
the chuck with a multi-purpose light oil (like 3-IN-ONE oil) on a rag.
Wipe the parts down with a rag to avoid over-lubricating the chuck, as
this will only attract dust and could result in staining the workpiece.
• Prevent Rust: The patented quick release chuck’s operation can be
affected by rust. Rust on any of the chuck parts or bit adapters will
cause the chuck to perform poorly and eventually fail. Specifically, any
rust on the surface of the mating tapers will prevent the bit adapter from
sitting in the tapered body correctly. In the best case, this will cause the
bit to be loose in the taper affecting cut quality and at the worst cause
the bit to be thrown out of the chuck during operation. In the event that
