Basic Operations - Jet JJP-10BTOS Operating Instructions And Parts Manual

Basic Operations

Dust Collection
Before initial operation, the machine must be
connected to a dust collector.
Important: If a dust collection system is not
used, the quality of your cut will suffer severely.
Initial Startup
After the assembly
complete the planer is ready to be tested. Plug
in and start the machine. Keep your finger on
the Stop button in case of a problem. The
machine 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 machine 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,
unplugged, and come to a complete stand-still.
To change the mode of operation, see sections
Jointer Setup and Planer Setup on page 12.
Jointer Operations
Correct operating position
The operator must be positioned offset to the
infeed table (Figure 18).

Hand placement
Never pass hands directly
over the cutterhead.
Referring to Figure 18:
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 18) 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 surfacing on a jointer is to
produce one flat surface (Figure 19). 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" or less 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.
