Problem Possible Cause Remedy
The edges of the molding knives are
visible in the machined moulding prole.
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 (or, if necessary,
some tenth of a millimetre more)
using Logosol’s setting block (ref.
no. 7500-000-1020) or a magnetic
adjuster for the upper cutter (ref. no.
7500-001-0050).
2. Regrind the moulding knives so that
their edges do not protrude over the
level of the planing knives, or use
adjustable, short knife clamping gibs
(ref. no. 7000-000-9506) to adjust
the moulding knives correctly.
The planing knives cut away the highest
points of the moulding pattern.
1. The planing knives cut away too
much wood.
2. The moulding knives are ground
incorrectly.
1. Set the takeoff of the planing knives
to 1 mm (or some tenth of a millimetre
less) using Logosol’s setting block
(ref. no. 7500-000-1020) or a
magnetic adjuster for the upper
cutter (ref. no. 7500-001-0050).
2. Use adjustable short knife clamping
gibs (ref. no. 7000-000-9506)
to adjust the moulding knives
correctly.
The width of the machined board differs. 1. The workpiece moves away from
the side fences.
2. The locking handle of the movable
cutter has not been tightened.
3. The pressure rollers are set
incorrectly.
4. The spring mechanism of the
pressure rollers is stiff.
5. The workpiece is too small for the
measurement the machine is set to.
6. The stationary side cutter cuts away
too much wood.
1. The right-side fences are set
incorrectly. Adjust them according to
the instructions on p.18.
2. Pull the handle tight before planing/
moulding.
3. Adjust the L bracket on which the rst
two pressure rollers are mounted
and also adjust the pressure roller
behind cutter 3. (See p.19.)
4. Clean and lubricate the spring
mechanisms of the three pressure
rollers.
5. Choose a wider workpiece or set the
machine to less width.
6. Decrease the feeding speed or the
takeoff of the stationary cutter.
The surface of the workpiece’s right side
is below par.
1. The locking handle of the movable
side cutter has not been tightened.
1. Pull the handle tight before planing/
moulding.
Splinters are being battered out of the
workpiece when it reaches the movable
side cutter.
1. Too much takeoff.
2. The chip deector is incorrectly
mounted.
1. Plane the workpiece into size before
the nal machining.
2. Mount the chip deector so that it
presses against the workpiece in
front of the cutter (see p.19).
