ADJUSTMENTS
Know the Transmitting Rollers of Your Planer
A – Anti-Kickback Fingers
B – Infeed Roller
C – Chipbreaker
D – Cutterhead
E – Pressure Bar
F – 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

Anti-Kickback Fingers

The anti-kickback fingers (A, Fig 23) help prevent kickback
of stock. They operate by gravity and it is necessary to inspect
them occasionally to make sure they are free of gum and pitch,
so that they move independently and operate correctly.

Table
Height of infeed roller, chipbreaker, pressure bar
& outfeed roller
The infeed roller, chipbreaker, pressure bar and outfeed roller
are adjusted at the factory. The infeed roller and the
chipbreaker should be set at 0.004" (0.1mm) below the
cutting circle; and the outfeed roller should be set at 0.02"
(0.5mm) below the cutting circle. See Fig. 25.
If an adjustment to the infeed roller, chipbreaker, pressure
bar or outfeed roller is necessary, use the following steps as
an example of procedure.
To check and adjust the outfeed roller below the cutting
circle, proceed as follows:

Adjusting infeed & outfeed roller
spring tension
To adjust the spring tension of the infeed
and outfeed rollers, turn screws (G & H,
Feed
Fig. 24) with a hex wrench. Turn screws on
opposite end of infeed/outfeed rollers in
the same manner.
Cutterhead
0.008" (0.2 mm)
1. Disconnect machine from power source.
2. Make sure the knives are adjusted properly as previously
explained under "Checking & Adjusting of Knives."
3. Place the gauge block (J, Fig. 26) on the table directly
underneath the cutterhead (D, Fig. 26). Using a 0.02"
(0.5mm) feeler gauge (K, Fig. 26) placed on top of the
gauge block, raise the working table until the knife just
touches the feeler gauge when the knife is at its lowest
point. Do not move the working table any further until
the outfeed roller is adjusted.
