Blimey makes you wonder if it's all worth it, maybe that's why they're the way they are, they have no intention of helping you or sending out a new tool.
I guess its to be expected with Chinese tools.
Our HS officer type woman bod in a previous meeting asked us all to list any tools we had and used that vibrated, drills, grinders, nail guns etc etc as she was in the process of compiling the trigger times for us to reduce the risks of hand arm vibration, most of the guys had company bought Ryobi tools, me on the other hand is like the one man dewalt road show if you open my van. We all gave her the serial numbers and she went away to get the relevant trigger times from them, after a few weeks she came back to us all and said Dewalt and Makita were the only 2 that had the info on their websites OR could gladly email all the info she needed which they did without any fuss, all the info within an hour, ryobi on the other hand she said were a nightmare, Chinese and unhelpful, they told her to contact the retailer. So B&Q here she comes, the MD of B&Q basically hadnt got a clue and said they werent obliged to supply trigger time data either on the box or within because ryobi is classed as a diy tool and not trade, she replied asking if the tools are available to buy through the tradepoint counters which he said they were, so basically by selling to the trade they needed by law I think to be able to supply the trigger times but apparently Ryobi cannot supply this info, so if you ever try and buy a ryobi tool through the tradepoint counter they'll direct you to the retail checkouts, I found it so funny because she can't get the trigger times she forced all the guys to throw their ryobi stuff in the skips and they all went out on a shopping spree, needles to say our MD wasn't too happy
Chinese tools, just keep clear
