Yes, I am a maintenance trainer for chairs and carpet/flooring. I have had good response from the Congregations where I have taught classes. Mostly older ones were in my classes - but, there was a satisfying number of young ones at the Hall and many of them were in teams for trades that benefited greatly having young, fit, willing helpers. One thing to keep in mind is that the JHA and Task Card for a given trade is to be "tailored" to the Hall where the training is taking place. Not all Halls have the same equipment or needs. For instance, some KH's have stack-able chairs, some have folding chairs and some have "theater" chairs. While all of these chairs have similarities, like they all have seat cusions, thay are not all built the same and have very different hardware needs. One of the things I do is cover the JHA and the Task Card with the volunteers and explain/ask why some of the cautions are in place and ask if they can think of any additional ideas. If they do think of something that is valid, simply add it to the needed form for updating by the LDC staff. I also show any "special" tools needed for the job and include any cautions needed to use these tools - for instance, a carpet knife can be quite dangerous. I walk them through the start of the task and then let them have "hands on" experience - they do not learn as much if they just watch me do all the work. On my last Hall, we needed to repair the lectern on the stage since it would no longer adjust properly. I waited until all the carpet and the chairs had been inspected and any needed repairs completed before addressing the lectern. That way, all in the group could be present while we disassembled the lectern to see what was wrong. We were able to fix it. However, since the lectern they use for the second school was beyond reasonable repair, we recommended replacing the one on the stage and moving the one we repaired to the second school. This helps them learn that it is OK to recommend work/replacement that cannot be done on the day of the maintenance. Some of the trades have them take things apart even though there are no "problems" - this way they learn how to fix things if there were a problem. For instance, they removed and reinstalled the traps in the restroom sinks so they could see how they work and how they are replaced, if needed. The Brother doing the irrigation had them dig up a valve in the back area of the yard even though there were no bad valves so they could see how they look and how to dig one up without damaging it. On another Hall, they actually replaced a bad valve. Typically, a Maintenance Trainer Overseer will be assigned 8 KH's. A Skill Trainer may be asked to assist more than one MTO in his area. I currently assist three. I do not teach at all 8 Halls for each MTO but I do teach at Halls in my general area covered by these various MTO's You may also want to watch the video Trained as Safe, Skilled Workers, found in the Video on Demand section of tv.jw.org under Our Activities >Theocratic Schools and Training.
