INSTALLING & REMOVING THE CHUCK
AND ARBOR
IMPORTANT!
It is important that the
tapered hole in the chuck, tapered hole in the
spindle and both tapered ends of the arbor
are free of any grease, oil, lacquer or rust
protection.
These tapered surfaces must be absolutely
clean for a precision fitting of the parts, so
slipping of the chuck during use does not
occur unless there is extreme rotational
pressure during use. This is a safety feature
of this type of friction fit joint.
INSTALLING THE CHUCK AND ARBOR
1. Open the chuck jaws as wide as possible to
prevent any damage. (Fig. 10)
2. Insert the arbor (A-Fig. 11) into the chuck
(B-Fig. 11) as shown. Make sure that the arbor
end and receiving tapered hole in the chuck
body rear are clean of grease, oil, rust
protection and any burrs or scratches that
disrupt the taper surface.
3. Carefully insert the chuck and arbor assembly
into the spindle, making sure to align the flat
part of the arbor with the spindle. (Fig. 12)
4. Using a mallet or wood and hammer, drive the
chuck and arbor assembly into the spindle.
This will properly seat the chuck assembly on
the spindle. (Fig. 13)
ASSEMBLY WITH A METAL HAMMER. This could
damage the chuck assembly or spindle.
5. Close the chuck jaws with the chuck key
provided.
