Troubleshooting
The entire surface is fuzzy.
1. The workpiece has high moisture
content.
2. The knives have lost their
sharpness.
1. Dry the timber before machining it.
2. Grind the knives. It is especially
important that the knives are sharp
when soft or moist wood is being
machined.
Fuzzy surface around knots,
where the direction of the fibers
can vary.
1. The workpiece has high moisture
content.
2. The knives have lost their sharp-
ness.
3. The workpiece is of a too soft sort
of wood.
1. Dry the timber before machining it.
2. Grind the knives. It is especially
important that the knives are sharp
when soft or moist wood is being
machined.
3. Choose another material, or sand the
workpiece after it has been machined.
The thickness of the board does
not correspond to the setting of
the scale.
1. The takeoff of the knives in the
upper
cutter are set incorrectly.
2. The pointer of the height scale is
set incorrectly.
1. Set the takeoff of the planing knives
to 1 mm, using the setting block sup-
plied, or a straightedge.
2. Machine a test board, measure it and
set the pointer to this measurement.
Fine-tuning of measurements should
always be done using the rotating scale
of the height-adjusting crank, which can
easily be reset. The scale shows 1 mm
every quarter of a turn.
The edges of the molding
knives are visible in the
machined moulding profile.
1. The planing knives do not cut
away enough wood.
2. The moulding knives are ground
incorrectly
1. Set the takeoff of the planing knives to
1 mm, using the setting block supplied,
or a straightedge.
2. Regrind the moulding knives so that
their edges do not protrude over the
level of the planing knives, or use adjust-
able, short knife clamping gibs to adjust
the moulding knives correctly.
