7. Troubleshooting
Clamping mechanism
will not hold the load
Clamping pressure is too low
Adjust the clamping pressure as necessary using
the pressure adjustment knob on the rear of the
machine.
Load is too short for clamp to secure Verify the load is of a size the machine is capable of
securing. See section 5.2.1. Load Restrictions.
Machine will not
rotate load (motor
runs)
Maintenance chains engaged Verify the maintenance chains are not engaged.
Motor may be turning in the wrong
direction (three phase machines)
Check motor rotation direction (counter clockwise as
viewed from the shaft end of the motor). If motor is
rotating the wrong way, swap any two phases.
The load exceeds the maximum capacity Verify load weight does not exceed the rated
capacity. See section 5.2.1. Load Restrictions.
Hydraulic uid level may be low Check the hydraulic uid level. Add uid as
necessary. See section 9. Hydraulics.
Pivot assembly may be damaged Inspect the turret bearing, pivot arm, and hydraulic
cylinder for damage.
The machine will
not clamp or rotate
(motor runs)
Hydraulic uid level may be low Check the hydraulic uid level. Add uid as
necessary. See section 9. Hydraulics.
Maintenance chains engaged Ensure maintenance chains are disengaged before
operating.
There may be a hydraulic leak Inspect the hydraulic system for leaks.
Supply voltage may be low
Verify the supply voltage is within 10% of the rated
voltage for three phase machines or 5% of the rated
voltage for single phase machines.
Motor may be turning in the wrong
direction (three phase machines)
Check motor rotation direction (counter clockwise as
viewed from the shaft end of the motor). If motor is
rotating the wrong way, swap any two phases.
The machine will
not clamp or rotate
(motor does not run)
Emergency stop may be pressed Verify the emergency stop button is not pressed.
Controls may not be functioning Inspect the controller and control cord for damage.
Repair or replace as necessary.
The machine may not be receiving power
Verify the machine is receiving the correct supply
voltage. Supply voltage must be within 10% of the
rated voltage for three phase machines or 5% of the
rated voltage for single phase machines.
