Basic Operations
Dust Collection
Before initial operation, the machine must be
connected to a dust collector.
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
equipment.
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 sections
Jointer to
Planer Setup
and
Planer to Jointer Setup
on
page 9.
Jointer Operations
Correct operating position
The operator must be positioned offset to the
infeed table (Figure 16).
Figure 16
Hand placement
Never pass hands directly
over the cutterhead.
Referring to Figure 16:
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 16) 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 17). 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 inches
or thinner than 3/8 inch without the use of a
special work holding fixture.
Never surface pieces thinner than 3 inches
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.
Figure 17
Direction of Grain
Avoid feeding work into the jointer against the
grain (Figure 18).
