My 4-year old GOP 18v developed a fault today, I  accidentally switched it on with the blade release lever fully open - yes stupid I know. The blade locking collet is now stuck in the locked position no matter where you put the release lever so a blade cannot be fitted. Does anyone know this fault - is it broken inside or can it somehow be reset? I am torn between sending it to Bosch (tool gone for a week) or getting a new bare unit in a couple of days, as I will be lost without it. I notice the new units are now called GOP 18 V-28  -  what does the V-28 mean?

Hello Bob Hutt.
I have heard of this problem once before from a buddy. He managed to free his eventually by brute force, using pliers to squeeze the locking jaws in with the locking lever fully open. I'm pretty sure it took him a few attempts and some jiggling as he wasn't best pleased.
Worth a go. Failing that, you might have to remove the gearbox head and have a look inside or hand it over to a Bosch service center.
As for "what does the V-28 mean" with the GOP 18V-28 I'm not 100% but the "V" stands for volt - as in 18 volt. The 28 might refer to the tools 2.8 degree oscillation arc.
The diffeence between the GOP 18V - EC and the GOP 18V - 28 is the 28 has greater oscillating arc and features the Stalock Plus blade change as opposed to the satandard Starlock of the 18V-EC.
Hope this helps.

Thanks Bailey, I stripped it down to find the gearbox casting broken. Given the likely cost of repair and the urgency, I went to my local SF for a new bare unit, but was slightly stunned to find that my universal blades wont fit in the new Starlock system. So although I decided some years ago to stick with the blue, Bosch have just lost me as a customer and SF refunded the new bare unit I bought on their web site and I bought a yellow machine. Bit miffed I must say but I will not be limited to buying only Bosch blades - I have used many blades since my 1st GOP 10.8 in 2009, and only use one make now which are far superior and half the price than "OEM" , and miffed that I had to pay for new batteries, but no doubt my perfectly good (and excellent) 18v bosch batteries will sell easily.

Bad luck Bob.
As of yet, I think it's only Bosch and Fein using the new Starlock Plus. As major accessory suppliers I think they were planning on it becoming an industry standard like SDS. And yes, neither the old Starlock nor the older 12 pin OIS blades work in the new system. It's a good system but it does mean an expensive pain in the arse for those wanting to upgrade/replace their tool.
Don't have any yellow machines myself these days but have to say, their current crop doesn't look that bad to be honest. And you'll have no probs selling your Bosch batteries. They hold a price pretty well on eBay.
All the best.
