7 ADJUSTMENTS
This machine has a helical cutterhead with four rows
of carbide knife inserts. Each of the 40 inserts on the
cutterhead are indexed and have four sharpened sides.
If the knives become dull, or one becomes nicked, simply
loosen the retaining screws with the supplied star head
screwdriver, lift up and rotate the inserts to a new sharp-
ened edge. No setting is required, as the cutterhead has
been machined to automatically index and set the inserts
in proper position for use. When all four sides of an insert
are dull, the insert can be easily removed and a new
carbide insert placed in the location.
To rotate or remove a carbide insert knife:
- Unplug power cable.
- Remove the screw (#203), that holds the Insert in the
cutterhead, and the insert cutter (#202). FIG. 7.1.2
- While the insert is removed, clean any resin buildup or
trapped dust from the surfaces of the cutterhead with a
suitable solvent. A tooth brush works well for safe clean-
ing around the sharp inserts. Any accumulated dust can
affect the seating of the insert in the cutterhead.
- Rotate the insert so that a new sharpened edge is in
position. The inserts have a indication mark on their top
surface corner, so that you can reference the positioning
of the dulled or sharpened edges of the insert. FIG. 7.1.1-
7.1.5.
- Tighten the insert’s set screw to lock the insert back in
position. DO NOT overtighten the screw or damage to the
insert may result. Torque to 50-55 in/lbs.
- Plug in the power cable when you are ready to resume
jointing.
Wear gloves when changing knife inserts to avoid the
risk of personal injury by cuts that may result from
touching the sharp edges!
