Thought I was ready to be put out to pasture this arvo.
Went to replace the blade in the Ex21, fitted it in the top clamp and I'd be buggered it was to short to fit in the lower clamp. 1st thoughts, " I must of grabbed a broken blade" nope it checked out against another from the packet "Maybe the whole damn packet was short?". Nope it was the same size as an old blade I had handy. Well that was just bloody marvellous, something had to be wrong with the saw, it was all I needed. Then I noticed the tension wheel, arm adjusting wheel's white line had disappeared. Grabbed a tape and sure enough, the front of the arm was 10mm wider apart than then the rear,. I have never had this happen before. The culprit was the Dewalt which I had been using, It's fixed to the same bench. The vibrations must of turned the knob. A sigh of relief, adjust the arms parallel again and of we went.
The air was pretty blue by this time
