Helical Cutterhead
WARNING!
Knives are extremely sharp. Be very careful
when handling knives. Failure to comply
may cause serious injury!
The helical cutterhead is set-up with the same
relationship to the in-feed roller, chipbreaker,
pressure bar and outfeed rollers as the straight knife
cutterhead. The planer comes set up from the factory
and shouldn’t need any adjustment.
If you find adjustment is necessary, follow
the steps on pages 10-11 for setting the in-
feed roller, chipbreaker, pressure bar and
outfeed rollers in relation to the helical
cutterhead.
When it is time to rotate the carbide knives
ALL knives must be rotated at the same time.
This is the same when replacing carbide
knives ALL knives must be replaced at the
same time. Mark the knives with a marker
so you know which knives have been
rotated. You can rotate the knives three
times before replacing. Use the provided
tork wrench to rotate, or remove knives.
V-Belt Adjustment
Three V-belts A,Figure 21) drive the
cutterhead. The single V-belt (B, Figure 21)
drives the in-feed and out-feed rollers.
Belt tension has been set at the factory. If
the belts have stretched and need
adjustment.
1. Disconnect machine from power source.
2. Open lower rear, and lower left-hand side
panels. Loosen and tighten four
adjustment nuts (C, Figure 21) to move
motor plate up, or down to increase, or
decrease belt tension. Tighten nuts
against motor plate after adjustment is
made.
3. Belts are tensioned properly when
moderate finger pressure can deflect the
v-belts about a 1/4"-1/2” midway
between the pulleys.
