WARNING: After installing knives, re-check
all gib screws. Loose gib screws can result
in knives being thrown out of the cutterhead,
causing severe damage to the machine and
possible serious or fatal injury to the operator
or bystanders.
THE FEED SYSTEM OF YOUR PLANER
(Figure 9)
1. Anti-kickback fingers
2. Infeed roll
3. Chipbreaker
4. Cutterhead
5. Pressure bar
6. Outfeed roll
ANTI-KICKBACK FINGERS
Anti-kickback fingers help prevent stock from being
thrown from the machine. These fingers operate by
gravity and should be inspected before each day's use
for pitch or gum buildup. The fingers must operate
freely and move independently for correct operation.
INFEED ROLL
The function of the infeed roll is to feed the material into
the machine. It is a corrugated, sectional roll with
approximately 5/16" independent movement of each
section to accomodate multiple board surfacing.
To provide proper drive, it should be set so that the
bottom of its arc is 1/16" (1.6mm) below the arc of the
cutterhead knives. The infeed roll is 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
boards. The tension should be equal at both ends of
each roll.
