Cleaning &
Protecting
Cleaning the Model G0939/G0940 is relatively
easy. Vacuum excess wood chips and sawdust,
and wipe off the remaining dust with a dry cloth.
If any resin has built up, use a resin-dissolving
cleaner to remove it.

Lubrication

There are four primary systems that require peri-
odic lubrication: the cutterhead elevation lead-
screws, the feed roller chain drive, the table height
chain, and columns. Clean the components in this
section with an oil/grease solvent cleaner or min-
eral spirits before applying lubrication.
