Squaring Headstock - Grizzly G0841 Owner's Manual

Squaring Headstock

squaring headstock
To reduce risk of shock or
accidental startup, always
disconnect and lock-out
machine from power before
adjustments, maintenance,
or service.
ONLY perform the following procedures
if you are certain the headstock is out-of-
square. Attempting these procedure on an
already square headstock will cause addi-
tional misalignment.
The headstock is properly squared to the planer
table at the factory and should only require
adjustment if the elevation leadscrews become
misaligned. Elevation leadscrews may become
misaligned if they are not lubricated regularly,
or there is a limit switch failure and leadscrews
are driven past headstock height capacity. If you
notice the headstock binds when raising or lower-
ing, then check to see if headstock is square to
planer table.
