MAKE SURE THE MACHINE HAS BEEN TURNED OFF AND UNPLUGGED FROM THE POWER SOURCE BEFORE PERFORM-
ING ANY MAINTENANCE OR ADJUSTMENTS.
INSPECTING CUTTER HEAD INSERTS
Observing planed workpieces as they come off of the
machine and looking for signs of knife damage or
wear is the best method to help you to determine when
knives are due to be changed.
Signs to look for include:
1.
A raised ridgeline in the workpiece that runs a
straight line from beginning to end of the board
D. This is generally an indication that one or more
knives has been nicked or damaged E by a foreign
object such as a nail, staple or other hard object
hidden or embedded in the workpiece.
2.
A slight washboard or chatter effect F which can
be an indication of uneven knife wear causing one
knife to cut slightly deeper than the others.
3.
Rough, irregular, torn or fuzzy grain on a fresh-
ly planed surface may be a sign of worn or dull
blades causing the wood to tear out. Sharp blades
cut crisply and leave a relatively smooth finish.
Note: Fuzzy grain can also be a sign of high moisture content in the workpiece. If inserts have recently been changed or
if you suspect that moisture content and not dull inserts is the cause, set the workpiece aside and test by planing other
boards with known or acceptable moisture content. If the planed results using a different workpiece are smooth, then
moisture content in your wood is the problem - no adjustments can be made to the machine for this. Set the "wet" stock
aside and simply work with drier wood.
