ADJUSTMENTS
ADJUSTING THE CUTTERHEAD
The Cutterhead that holds the knife inserts is fastened to
the machine's cabinet, and is not adjustable. Based on
the postion of this main component of the machine, all of
the other parts - rollers and tables - are then pre-set by
the factory to align with the cutterhead. Should any of
the tables or rollers get out of parallel with the cutterhead,
they can be adjusted separately following the instructions
in this manual.
NOTE: The Cutterhead's Guard / Chip Breaker (#53,
FIG. 20) is also pre-set by the factory to align correctly
with the cutterhead. This guard must never be removed
except for adjustments or maintenance purposes to the
cutterhead assembly.
ADJUSTING THE FEED ROLLERS
The Infeed (#65) and Outfeed (#66) Rollers are pre-set
by the factory to align parallel with the cutterhead and
knife inserts. These spring loaded rollers are set just
below the cutterhead, so that they engage the lumber
and move it through the planer. Should an adjustment be
required to increase or decrease the amount of down-
ward pressure they exert on the lumber, the following
steps are needed.
1. Make sure that the planer/jointer's switch is turned off,
and the plug is disconnected from the power source.
2. Lift the planer's upper Cover (#13) to access the
cutterhead assembly. FIG. 21 & 22.
3. Adjusting Downward Pressure for the Feed Rollers is
done by the Springs (#47, A) positioned above the Roller
Shaft ends (C). Adjusting the pressue is done with the
Set Screws (#48, B) that are above the springs.
- By raising the hex nuts UP, the spring compression
is reduced and the downward pressure on the rollers is
decreased upon the lumber being fed through the planer.
- By screwing the hex nuts DOWN more, the spring
compression is increased, and the rollers exert more
pressure down onto the lumber.
NOTE: For changing of Roller Pressure, adjust the four
springs first, as changing the rollers' height (below) may
affect the rollers parallell alignment with the cutterhead.
4. Adjusting Feed Roller Height. Under the roller shafts,
the Hex Bolts and Nuts (#46, 45, D) can be turned with
an offset wrench to raise or lower the feed rollers as
needed to remain parallell to the cutterhead or to adjust
the roller pressure down on the lumber.
- By raising the hex bolts UP, the roller height is
raised. This will decrease the pressure upon the lumber
being fed through the planer.
- By lowering the hex nuts DOWN, the roller height
is lowered, and will exert more pressure down onto the
lumber.
THE MACHINE MUST NOT BE
PLUGGED IN AND THE POWER SWITCH MUST BE IN
THE OFF POSITION UNTIL ALL ADJUSTMENTS ARE
COMPLETE.
