6. Position the knife gauge over the knife as shown in
Figure 20.
7. Jack Screws—Using a 3mm hex wrench, find the jack
screws through the access holes in the cutterhead
(
Figure 22) and rotate the jack screws to raise or
lower the knife. When the knife is set correctly, it
will barely touch the middle pad of the knife set-
ting gauge. Snug the gib bolts tight enough to just
hold the knife in place. Repeat
Steps 5-7 with the
remaining knives.
Springs—Push the knife down with the gauge so that
the knife edge touches the middle pad of the gauge.
Hold the gauge down and tighten the gib bolts just
tight enough to keep the knife in place. Repeat
Steps 5-7 with the remaining knives.
8. Rotate the cutterhead to the first knife you started
with. Slightly tighten all the gib bolts by following
the tightening sequence shown in
Figure 23. Repeat
this step on the remaining knives.
9. Final tighten each gib bolt, then reinstall the top
cover, dust hood and V-belt cover.

hole.
Chain Tension
The chain drive can be adjusted to remove slack if the
chain stretches over time or is loosened during table lev-
eling procedures.
To adjust the chain tension, do these steps:
1. DISCONNECT THE PLANER FROM THE POWER
SOURCE!
2. Remove the motor and front access panels.
NOTICE
During the next step, DO NOT let the chain fall off
the sprockets. Returning the chain to its proper loca-
tion without changing the table adjustments will be
very difficult and time consuming.
3. Using a 14mm wrench, loosen the two lock bolts,
move the idler sprocket against the chain to tighten
it (
Figure 24) and re-tighten the locking bolts.
4. Check chain lubrication. Refer to LUBRICATION on
Page 23 for further details.
