Three-Phase Test Run
On the three-phase unit, after wiring has been
completed, you should check that the wires
have been connected properly:
1. Connect machine to power source and
press the start button, shown in Figure 10.
(See “Operating Controls” on page 25 for
further information on the control 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 (Figure 10) and disconnect
machine from power.
3. Switch any two of the three wires at "R,S,T".
Adjustments
Drive Belt Tension
To check or adjust the drive belt tension:
1. Unscrew the knob (A, Figure 11) and
remove the belt guard (B, Figure 11).
2. Remove the rear panel (C, Figure 11) by
unscrewing the four flat head screws (D,
Figure 11) with a cross-point screwdriver.
3. Proper drive belt tension is achieved when
there is a small amount of deflection in the
drive belt midway between the pulleys,
when using moderate finger pressure
(Figure 12).
4. To increase the tension on the drive belt,
loosen the lower hex nut (B, Figure 13) with
a 17mm wrench, and tighten the top hex nut
(A, Figure 13). When finished, tighten lower
hex nut (B, Figure 13).
5. Re-install rear panel and belt guard.
NOTE: After operating the machine for a short
time, the drive belt tension should be re-
checked, as the new drive belt may stretch
slightly during the “breaking-in” period.
Drive Belt Replacement
1. Unscrew the knob (A, Figure 11) and
remove the belt guard (B, Figure 11).
2. Remove the rear panel (C, Figure 11) by
removing the four flat head screws with a
cross-point screwdriver.
