Machine Operation Do's and Don'ts:
1.0 Do not smash the pipe or tube linearly into the chuck.  The gearbox bearings can be damaged.
2.0 Do not apply bending forces to the chuck.  This is not a reference to an A-Axis torque.  Instead a bending force would be applied by leaving a long length of material hanging out of the chuck unsupported.  Similarly, an opposite bending force can be applied when cutting a longer part and not supporting it with an outbound, outboard carrier such as a simple pipe stand.  Obviously, the weight-per-foot and the length of the material both determine the force applied to the bearings in the rotating assembly.  The limit for the 2100-series machine is 30 ft-lbs.  This is the equivalent of 30lbs hanging on a 12" length of pipe sticking out of the jaws.  The gearbox bearings are the limiting factor.  On the 2400-series machines the torque limit for the front rotating assembly is 90 ft-lbs depending on jaw configuration.  This is the equivalent of 90lbs hanging from a 12" long piece of material.  The gripper assembly is the limiting factor on the 2400-series machines.
3.0 Do not turn off the main power without shutting down the software side of the control first.  There is a Windows based computer in the cabinet.  Turning off the power prior to doing a standard shutdown will cause file corruption as with every computer.
4.0 There is a surge suppressor and electrical noise filter in most every machine.  If your machine does not have one it can be added in every case.  They all have indicator lights and fault monitoring circuits.  They should be inspected every six (6) months, after any known power surge, and after any known power outage.  These devices are there to protect the more expensive and critical components in the control.  It is expected that in time they will fail while absorbing the spikes and noise that would otherwise cause damage to the sensitive control components.  If there is a question about interpreting these indicator lights or circuits, please contact your service provider.  In many cases the machine will remain operational even after this component goes inoperable, however replacing it immediately is part of the warranty requirement and a wise investment.
5.0 If your shop experiences frequent power outages or brownouts, please talk to your service provider about having an industrial UPS (uninterruptable power supply) installed.  Remember in almost every case people have their home and office computers plugged into a UPS and Surge Suppressor.  How much more important is it to protect an expensive industrial tool in a nasty environment?
6.0 Do not modify the networking addresses and protocols assigned in the machine when it was delivered.  The DHCP setting on the public port will permit most installations to access the internet for remote support.  If it is necessary to put the machine on a secure network for file sharing and so forth, please consult your service provider first.
7.0 Do not adjust the tension on the main drive belt.  The 2100-series machines and some 2400-series machines use a large, toothed belt to position X-Axis.  These belts are tensioned at the factory and the machine is then calibrated.  It is not a process that should need repeating until years down the road.  Depending on model the belt can be at 1800lbs of actual tension or more.  It requires specialized tools to handle it safely.  If there is a reason to get involved with the belt please contact your service organization.
8.0 Do not install anti-virus software on the machine.  It will slow down the Real Time Data Packets on its internal network to the point that the machine will show errors.  If there is reason to scan the machine do it from a removable drive or a remote/network appliance.  Do not adjust the windows fire wall settings, they should all be off.
