11.0 Basic Operations
11.1 Dust Collection
Before initial operation, the machine must be
connected to a dust collector.
11.2 Initial Startup
After the assembly and adjustments are
complete, the planer is ready to be tested. Turn
on the power supply at the main panel. Press the
start button. Keep your finger on the stop button
in case of a problem. The planer should run
smoothly with little or no vibration or rubbing
noises. Investigate and correct the source of any
problems before further operation.
DO NOT attempt to inves-
tigate or adjust the planer while it is running.
Wait until the planer is turned off, unplugged,
and all working parts have come to a
complete standstill.
Always wear ANSI-approved
safety glasses or goggles when operating the
planer-jointer.
11.3 Changing Mode of Operation
When changing the operating mode (planer to
jointer and back), the machine must be turned off
and at a complete standstill. To change the mode
of operation, see
sect. 9.1, Jointer to Planer
Setup and sect. 9.2, Planer to Jointer Setup .
11.4 Jointer Operations
Correct Operating Position
The operator must be positioned offset to the
infeed table (Figure 27).
Hand Placement
Never pass hands directly
over the cutterhead.
At the start of the cut, the left hand holds the
workpiece firmly against the infeed table and
fence while the right hand pushes the workpiece
in a smooth, even motion toward the cutterhead.
After the cut is under way, the new surface rests
firmly on the outfeed table. The left hand is
transferred to the outfeed side (Figure 27) and
presses down on this part of the workpiece, at the
same time maintaining flat contact with the fence.
The right hand presses the workpiece forward
and before the right hand reaches the cutterhead
it should be moved to the work on the outfeed
table.

Surfacing
The purpose of planing on a jointer is to produce
one flat surface (Figure 28). The other side can
then be milled to precise, final dimensions on a
thickness planer, resulting in a board that is
smooth and flat on both sides and each side
parallel to the other.
 If the wood to be jointed is cupped or bowed,
place the concave side down and take light
cuts until the surface is flat.
 Never surface pieces shorter than 12" or
thinner than 3/8" without the use of a special
work holding fixture.
 Never surface pieces thinner than 3" without
the use of a push block.
 Cuts of approximately 1/16" at a time are
recommended, which provides for better
control over the material being surfaced.
More passes can then be made to reach the
desired depth.
