The cutterhead knives on the Model G0505 are
extremely sharp. Merely brushing your finger
along the edge can result in a severe cut. Take
extreme caution when doing any adjustments
involving the cutterhead knives. Wear thick
gloves anytime it is necessary to manually
rotate the cutterhead assembly.
2. Insert the knife into the space between the
cutterhead and the locking bar. Make sure
the bevel side of the knife is against the cut-
terhead.
3. Position the knife setting gauge on the cutter-
head, as shown in Figure 17.
Make sure the Model G0505 is unplugged or
disconnected from the power source and mov-
ing parts have come to a complete stop before
investigating any problems or performing any
maintenance or adjustments. Serious personal
injury may occur.
To install and adjust the knives:
1. Make sure the two springs in the knife groove
are in position. If the knife locking bar was
removed, make certain it is re-inserted with
the bolts oriented as shown in Figure 16.
4. While holding the knife setting gauge with
one hand so it sits firmly on the cutterhead,
turn the gib bolts counterclockwise with the
other hand. Tighten the seven bolts until they
begin to contact the side of the groove. Then
tighten further, starting with the bolts at the
center and working toward the outer bolts.
Once all the bolts are tight enough to hold the
knife in position, remove the gauge.
5. Repeat steps 1-5 above to set the second
knife.
6. Final tighten each gib bolt. Recheck with the
setting gauge to make certain the knives did
not move. The knife tip should be barely
touching the top of the arc of the gauge as
shown in Figure 17.
7. Remove all tools and install the chip deflec-
tor.
