12.0 Basic Operations

12.1 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.

12.2 Initial startup

After the assembly and adjustments are 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 investigate
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.

12.3 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 sect. 8.0, Jointer
Setup, and sect 9.0, Planer Setup on page 12.
