Three-Phase Test Run
On the three-phase unit, after wiring has been
completed, you should check that the incoming
leads have been connected properly:
1. Connect machine to power source and
press the start button. Make sure cutterhead
is clear of all obstructions! (See page 21 for
more detailed instructions on the switch.)
2. The cutterhead should rotate clockwise as
viewed from the front of the machine. If the
cutterhead rotation is incorrect, press the
stop button and disconnect machine from
power.
3. Switch any two of the three leads to the
motor, then re-connect to power.
Extension Cords
Make sure your extension cord is in good
condition. Always use a cord that is heavy
enough to carry the current your product will
draw; the cord rating must be suitable for the
amperage listed on the machine’s motor plate.
An undersize cord will cause a drop in line
voltage resulting in loss of power and
overheating.
Use the chart in Figure 15 as a general guide in
choosing the correct size cord. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Adjustments
Disconnect machine from
power source before making adjustments.
Tools required for adjustments:
8mm & 12mm wrenches
4mm hex wrench
machinist's protractor or adjustable square
steel straight edge
Installing and Adjusting Knives
(Straight Cutterhead only)
Refer to Figure 16.
Use care when working with
or around sharp knives. Make sure power to
the machine has been disconnected.
When installing new knives, remove only one
knife at a time. Clean the knife slot and install
the new knife. Adjust and snug new knife in
cutterhead before proceeding to next knife.
