proper pressure on the workpiece helps avoid
kickback and keeps the workpiece from slip-
ping. however, as pressure increases on the
workpiece, snipe also increases (some degree of
snipe is normal with all drum sanders).

if snipe becomes a problem, you can minimize it
by reducing pressure. to lower pressure, turn the
lower adjustment bolts counterclockwise to raise
the pressure roller height. to increase pressure,
turn the lower adjustment bolts clockwise (lower-
ing pressure rollers).
