Southworth PalletPal Pallet Inverter/Rotator
Using an external lifting mechanism, such as a crane or a forklift.
Raise the machine and insert any and all maintenance devises.
3. Check the level of the hydraulic fluid. Use a dipstick to check
the oil level, add oil if necessary.
4. If the machine rotates but does not rotate completely, the ma -
chine may have an up limit switch. This switch may just need to
be re-adjusted.
CAUTION!
Do not disconnect the up limit switch. Instead, loosen
the adjusting screw and change the position of the arm.
If you do disconnect the switch, when the lift platform
moves up, it may not stop at the correct spot, the ma-
chine may be damaged and people may be hurt.
5. On a machine equipped with a three-phase motor, the motor may
be running backwards. If the motor has been wired correctly, the
machine should start to move in 2 or 3 seconds after you hit the
“CLAMP” or “ROTATE” button. If the machine does not move, try
reversing any two power leads.
6. On a machine equipped with a three-phase motor, the motor may
be “single phasing.” When this happens, the motor hums but does
not turn. If this is the case, one lead of the three-phase line has
been interrupted. Check the motor wiring and line fuses.
7. The power supply to the motor could be too low. Check the volt -
age at the motor when it is under a full load. The supply voltage
should be within 10% +/- of the rating.
8. The suction filter in the tank may be clogged. Clean the filter as
described in the maintenance section.
9. A vacuum leak may be allowing air into the suction line. This will
cause the pump to cavitate (loss of suction). Check all fittings in
the suction line and replace or repair if necessary.
NOTICE
If cavitation is allows to continue, the pump will be dam-
aged and will need to be replaced.
10. If the pump or the motor has been changed for any reason, the
coupling may not have been installed.
The machine clamps and rotates but fails to hold
the load:
1. Adjust the clamping force to hold the load (See page 12).
