Comments operation circa 2016
Comments: The rack and pinion table lift is somewhat loose - as the rack is new, but the previous, broken one, was showing signs of wear, it is probable that a new pinion is needed. This certainly explains the recent problems with the rack bending and breaking - if the rack and pinion mesh correctly, they can probably hold against drill pressure even if the table lift lock is not tightened.
The new chuck guard needs a replacement wedge to ensure that it doesn't catch on the power switch. This has caused breakage previously, and is a design flaw with these drills having the switch on the front.
