Tips for buying used robots

[Robotter]

Hello friends:

Many people are off late buying used robots and i thought it will be useful for used robot buyers as a reference.
I have numbered them for convenience so i request anyone who adds a tip to continue the numbering...
A few tips to consider while buying a used robot:

1) Always buy robots only from reliable sources (known companies or companies that have a reputation to protect)
2) Inspect the robot for missing hardware, software, batteries, physical damages, motor or reducer damages, big backlash etc.
4) Inspect the Teach pendant and the related cables
5) Check for the required IO board (or atleast a one that you could use)
6) Try to avoid autions with "as is  where is condition" terms
7) Do not buy too old robots - you will end up paying more for spares than the robot itself
8) Always insist on the manuals - robot manuals + the peripherals if accompanying
9) Ensure that the key spares for the robot are available in the market prior to buying the robot - Identify the spares suppliers too..
10) Be aware of the licensing policies from the used robot manufacturers. Make sure of the robot manufacturers' charges.

11) If you are not a robot expert, hire a qualified company / personnel. A few more dollars will ensure a good buy
12) if necessary get the robot refurbished / overhauled. A good start = lesser trouble during operation.
13) Greasing is recommended
14) Buy a couple of small spares alongwith the robot - fuses etc
15) If possible include the robot training in the deal - however it is recommended to avail this service from experts
16) Remember the packing and handling charges are additional.
17) Do not forget the applicable duties and taxes in addition to the transportation expenses
18) Avoid online buying - usually you discover a lot more that what is mentioned on the specifications
19) Some bigger companies offer warranty - check all the terms and conditions. read the fineprint meticulously
20) validate if the robot purchase meets the reach, payload and the accuracy requirements of your application
