depth of cut.
3. When you have set the proper depth of cut
for your operation, firmly tighten the lock knob
to secure the sanding drum in place above
the workpiece.
NOTICE
it is imperative that the elevation lock knob
is fully tightened before resuming the sand-
ing process. Otherwise, the sanding drum
will raise up under the pressure from the
workpiece and will not evenly sand it.
Depth of cut
the correct depth of cut when surface sanding
with the Model g0716 depends on many vari-
ables, such as the hardness of the wood, the
width of the workpiece, and the feed rate.
generally, a 1 ⁄
4
turn of the elevation handwheel
( 1 ⁄
32
" depth of cut) per pass is acceptable for
coarser grits or softer woods. a 1 ⁄
8
turn of the
handwheel ( 1 ⁄
64
" depth of cut) is recommended
for finer grits or harder woods. however, use your
best judgement to produce good sanding results
for your operation.
important: Keep in mind that, although the thick-
ness of the workpiece is reduced during sanding,
this process is not a replacement for thickness
planing, which should be done with a planer or
other acceptable tool/machine before beginning
the sanding process.
NOTICE
taking an excessive depth of cut could
cause the sanding motor to exceed the
available power source amperage. in this
case, the motor or power source circuit
breaker will trip. if this should happen, dis-
connect the machine from power, allow the
motor to cool, reset the circuit breaker, then
take a smaller depth of cut.
