Feeling both silly and satisfied at the same time right now. I read the (bleep) manual before starting, setup the two levers on the drill and set to drilling 26 - 30 holes in concrete.
14 holes in, over two days, and a lot of aching joints and muscles last week, I started up again this morning before the rain comes. 2 more hours done and I think that lever is showing a drill, not a hammer. Flick.
OMFG. 10 minutes later, 2 holes done. Hallelujah, hallelujah, hallelujah.
The rain is now arrived, so waiting until tomorrow so as not to mix water and electricity. But now looking forward to the job 🙂🙂
