Dust Collection
The 6” dust collection port (A, Figure 4) is
located below the outfeed table. Typically flex
hose is used to run from this point to a central
trunk line.
Note: Do not operate the jointer without dust
collection.
Electrical Connections
WARNING!
Electrical connections and wiring must be
performed by a certified electrician. The
machine must be properly grounded.
Failure to comply may cause serious
injury!
This jointer can be 1 or 3-Phase based on
your order and is wired for 220 volt. If on 3
phase you need to switch from 220V to 440V,
have a certified electrician make the changes.
As well, a step down control transformer will
have to be installed.
For 3 phase machines, bring your incoming
power leads up through the bottom right hole
of the case and tie to L1, L2, L3 as shown in
Figure 5. Then tie your earth ground to the
ground connection in the box.
For 1 phase machines, tie your incoming
power leads to L1 and L3.
Make sure the voltage of your power supply
matches the specifications on the motor plate
of the machine.
With 3-Phase power verify the cutter head is
turning in the proper direction. If rotation is
incorrect, swap two of the phases to reverse.
Note
: If running from a phase converter
ensure the ‘high leg’ of the converter does not
feed the control circuit.
Control Switch
For shipping purposes the control switch is
mounted as shown by ‘A’ in figure 6. Remove
the two mounting bolts and reposition the
switch as shown by ‘B’ while re-securing using
the two bolts.
