I bought a Hitachi 12V router about a year ago. I removed the plunger
springs and mounted it in the side table of my Unisaw. I installed the
Height Adjustment Knob that came with it as a bonus. After about four or
five times laying the router on its side to remove the bit, the knob broke
in half. Actually the whole knob broke off about half way down the shaft,
where the plastic joins the metal. I have been using half of a Height
Adjustment Knob for some time now.
The other day, I looked up Hitachi on the web and sent them an email telling
them in a pleasant way my disappointment in the quality of their "Knob". I
really didn't expect to hear anything back from them. To my pleasant
surprise, yesterday FedEx dropped off a package to me containing a brand new
Height Adjustment Knob. These things are $24.99 at Amazon.

Apparently Hitachi has had a lot of problems with the knob shaft breaking
because the new one's shaft is solid metal. I imagine it is much more
substantial than the old design. I am very pleased with Hitachi's customer
support. Thank you Hitachi.
