Adjusting Headstock
Travel Limits
The Model SB1122 is equipped with a limit
switch that stops the blade motor when a cut
is finished, a downfeed stop bolt that stops the
headstock from lowering when it reaches the
end of its travel, and a stop bolt for when the
headstock reaches its full height.
If the headstock does not completely cut through
a workpiece before it stops lowering or before
the blade stops, or if the blade cuts into the vise
table, you will need to adjust the limit switch and
the downfeed stop bolt.
Testing Downfeed Travel Limit
1.
Lower headstock as far as it will go. When
headstock stops, blade should stop and be
just below vise table, but not contacting it.
— If blade stops and is just below vise table,
but not contacting it, no adjustment is
required.
— If headstock stops when blade is just
below vise table, but not contacting it, but
blade does not stop, refer to Adjusting
Downfeed Limit Switch.
— If blade contacts vise table, raise
headstock until blade is just below
vise table surface. Refer to Raising
Downfeed Travel Limit.
— If blade does not reach vise table, refer to
Lowering Downfeed Travel Limit on
Page 50.
