Removing The Chuck
The Chuck is secured to the Chuck Shaft with three
M10 x 1.5mm hex cap screws. Using a 5/16 in. Allen
wrench, remove the cap screws to remove the Chuck
from the Chuck shaft.
Newer machines may be equipped with bolts that
require a 15mm wrench for removal.
When installing the Chuck, tighten the screws, then
give each one another quarter turn.
Cleaning The Chuck
Over time, the inner mechanism of the Chuck can become dirty, causing it to operate poorly.
Cleaning the inner mechanism can help the Chuck work smoothly again.
1. Remove the Chuck from the Chuck shaft.
2. Remove the Chuck jaws, noting the location of each jaw so it can be reinstalled in its
original location.
3. Clean the Chuck with brake cleaner, spraying the inner mechanism as much as possible. If
the Operator has access to a parts washer it is recommended the Chuck be cleaned in this
manner to more effectively flush dirt and slag from inside the Chuck.
4. With the Chuck clean, lightly lubricate the inside with a quality spray lubricant.
5. Reinstall the Chuck jaws, ensuring they are installed in the same location and on the same
rotation of the Chuck key.
6. Reinstall the Chuck. Tighten the Chuck mounting screws then give each screw another
quarter turn.
If the Chuck jaws are not installed on the same rotation of the Chuck key the Operator
will be able to perform a visual inspection and determine the jaws are not installed
correctly.
