10.9 Feed Roller Height Adjustment
Refer to Figure 23:
The height of the infeed and outfeed rollers has
been set by the manufacturer for planing
operations. If this setting should ever need
adjustment, it is done using the
screw (C) and nut
(B) at each end of the rollers. Two 10mm open
wrenches are required.
Note: The front ends of the rollers can be
accessed when the jointer table is raised and the
machine is in the planer orientation (see
sect. 9.1,
Jointer to Planer Setup ). The back ends of the
rollers can be accessed by taking off the jointer
fence assembly (A, Fig. 17) with a 5mm hex
wrench and the upper back panel (C, Fig. 17) with
a 4mm hex wrench.
Disconnect machine from
power source before making any
adjustments. Failure to comply may cause
serious injury.
1. Disconnect machine from power source.
2. Loosen the hex nut (B) and rotate the screw
(C) as needed to raise or lower that end of
the roller.
Note: Feed rollers must remain parallel to the
table, and about 1/32" below the cutting arc of the
knives or knife inserts.
3. Adjust any of the four screw/nut assemblies
as needed.
4. Use a gauge on the planer table to verify the
height of the rollers in relation to the
cutterhead.
5. When settings are correct, tighten the hex
nuts (B) up against the casting.
Note: Replace upper back panel (C, Fig. 17) and
jointer fence assembly (A, Fig. 17) if they were
removed to access the back ends of the rollers.
6. Make test cuts to verify the setting.
10.10 Feed Roller Pressure
Adjustment
Refer to Figure 23:
The pressure of the feed rollers against the
workpiece
during planing operations is
maintained by spring tension. To adjust this
tension, turn the
socket head screw (A),
clockwise to increase pressure or
counterclockwise to decrease pressure.
