When I got my machine it was 12 deg and I un-boxed it and let it warm up over night. When I went to use the CW the head was hard to raise and lower. I lubed the shafts and cranked it up and down about 100 times and each time it would get better. More lube more cranking and it freed up fine. I clean and lube my shaft each day.

Also found if you dry lube the too bit chuck and bit adapter and I never fight getting the bit out.
