1. Disconnect machine from power source.
2. Place the gauge block (Figure 21) on the work
table directly under the edge of a knife or knife
insert as shown. Make slight contact with the
knife edge by gently raising the table.
3. Move the gauge block to the opposite end of
the work table. The distance from the work
table to the edge of the knife should be the
same on both ends of the knife.
Adjusting Work Table Parallel to
Cutterhead
If the work table is not parallel to the cutterhead,
perform the adjustment procedure as follows:
1. Disconnect the machine from power source.
2. Tilt planer on its side to expose underside of
base, as shown in Fig. 22.
3. Remove bolt (A, Fig. 22) and loosen bolt (B,
Fig. 22) which will allow you to move the idler
sprocket assembly (C, Fig. 22) far enough to
release tension on the chain.
4. Remove chain from the particular sprocket on
corner of base that must be adjusted.
Turn the sprocket by hand to bring that corner
into adjustment with the other three corners.
NOTE: Turning sprocket clockwise will
increase the distance between the working
table and headcasting; counter-clockwise will
decrease the distance. This adjustment is very
sensitive and it should not be necessary to
turn the sprocket more than one or two teeth.
5. When adjustments are correct, replace chain
around corner sprocket, slide sprocket (C, Fig.
22) back to re-tension chain, tighten bolt (B,
Fig. 22) and replace and tighten bolt (A, Fig.
22).
Know the Transmitting Rollers of Your Planer
A – Anti-Kickback Fingers
B – Infeed Roller
C – Chipbreaker
D – Cutterhead
D – Pressure Bar
E – Outfeed Roller
The infeed roller (B, Fig. 23) and outfeed roller
(F, Fig. 23) are those parts of your planer that feed
the stock while it is being planed. The infeed and
outfeed rollers are under spring tension and this
tension must be sufficient to feed the stock
uniformly through the planer without slipping but
should not be so tight that it causes damage to the
board. The tension should be equal at both ends
of each roller.
