I don't know if anyone has got one but has anybody had any problems with the Bosch GST 135 BCE jigsaw at all. I'll be more specific on the problem if somebody says yes.
The GST135BCE seems to be the darling of the jigsaw world, and you won't find many people who have had problems. Indeed, quite a lot of people who have tried the much more expensive Festool PS300/PSB300 prefer the Bosch.
Having read lots of positive reviews about the GST135BCE, I went and bought one a couple of years ago, but I didn't get on well with my one at all.
(There are
photographs to illustrate problems 1 to 3)
Problem 1. Thicker genuine Bosch blades (eg the 1.7mm thick T144DP, supplied with he saw) didn't fit into the groove in the support roller. This meant that the "Precision Control System" (PCS) guides on either side of the blade did not give sideways support to the blade when pendulum mode was off, as the blade could not move back far enough to fit between the guides. Since neither the support roller nor the PCS guides properly supported the blade, there was very little lateral support at all.
Problem 2. Because the blade wanted to seat itself in the roller, but couldn't, after less than a minute of running, the support roller has started to wear a groove in the back edges of the blade.
Problem 3. This happened when the saw was put into any of the three pendulum modes with the 1.7mm thick blade and the PCS guides were engaged. The blade started to move back, but was obstructed from doing so by the PCS guides which had clamped shut behind it (see Problem No 1). However the blade continued to push back until it sprung the guides apart, and the blade then entered the gap. When the pendulum action moved the blade forward again, the guides clamped together, only to be forced apart again on the next cycle. The PCS guides ended up being continually forced back and then apart, and this repeated movement, at up to 2,800 times a minute, would have damaged the mechanism very quickly, as the guides are designed to remain stationary.
Problem 4. In the case of thinner blades, which did fit into the roller, the PCS guides clamped onto the side of the blade but pushed it to one side, resulting in a 1mm movement at the tip of the blade. The guides did not seem to be centred on the blade.
Problem 5. The soft-start feature was almost undetectable, and the saw jerked due to torque reaction every time I started it.
Problem 6. Whilst smooth and quiet at speeds 1 and 2, at speeds 3 to 6 the saw got rattly and I started to worry that there was something wrong inside. Vibration was also increased, and overall I was disappointed by the smoothness, vibration and noise. At speeds above 3, it felt and soundeds rougher than the 10 year old B&D Pro jigsaw I had previously. Oddly, the rattles and vibration were more severe when the pendulum action was off, which is the opposite of what I'd expect. I noticed all this before fitting any blades at all.
Problem 7. On two occasions, the T144DP blade refused to eject, and only did so when I gently started the saw.
Problem 8. On several occasions, the blade release mechanism got stuck in the open position, and pressure had to be applied to close it, rather than it springing shut on its own accord.
All in all, I was majorly disappointed in this much-heralded saw.
I returned it to the supplier and replaced it with a DeWalt DW331K which works brilliantly and is one of my favourite tools. It is super-smooth with no vibration.
