and let sit for an hour. After applying the specified lubricant slide the
core back into its sheath. When near full insertion, the core may
need to be carefully rotated with the fingers to ensure that its square
end engages correctly with the cutting motor. Once the core is fully
inserted in the sheath, it can once again be snapped into the cutting
head. Rotate the bit chuck if necessary to get the square end to
engage with the chuck.
o The patented quick release chuck’s operation can be affected by
rust. Surface rust can cause the bit adapters to stick in the chuck.
Periodically clean out dust from the chuck using compressed air
and/or a small stiff bristled brush. Once cleaned, re-lubricate the
chuck with multi-purpose light oil (like 3-IN-ONE oil). Always try to
keep a thin film of oil on the chuck and the bit adapters to deter rust,
to provide lubrication, and to help transfer heat between the bit
adapter and the chuck assembly during heavy use. Avoid over-
lubricating the chuck as this will only attract dust and could result in
staining the workpiece.
o The guide rods/rails upon which the cutting head assembly rides
need to be kept free of cutting debris. They should be wiped or
blown off before carving a project, and wiped occasionally with a thin
coat of light oil for lubrication. If the rails are allowed to accumulate
dust and debris, the machine will halt during usage and an error
message will be seen on the display with a reminder to clean the
rails. Once they have been cleaned, pressing the ENTER key on
the keypad will resume operation.
o The vertical guide rods at the corners of the machine also need to
be clean and rust free for smooth operation. A thin coat of lithium
grease applied to the rods will help keep them free of rust.
• Replacement Items: Occasionally, due to wear or accident, some
components of the machine will need replacement:
o The flexshaft will periodically need to be replaced. The time period
will depend on the duration and type of use the machine has had.
o Replace dented or damaged bit adapters.
o Use only correct factory supplied replacement set screws in the 1/4"
bit adapters.
o Belt replacement: The toothed belts used for various motion
functions are expected to last the life of the machine. If they are
damaged, they will require replacement at a CarveWright service
center.
o Traction belt replacement: The grit-faced traction used to grip the
workpiece and move it through the machine may need to be
replaced from time to time. Replacement belts can be purchased at
a CarveWright service center.
• Accessories and Parts Source: Available accessories, approved
cutting bits, and user-replaceable parts can be obtained through the
CarveWright website.
