LOG HOUSE MOULDER
Problem
Possible Cause
Remedy
The motor becomes overheated.
1. Wood debris has accumulated
on the motor and around its
cooling fan.
2. Dull knives.
3. Too low voltage in the power
supply.
4. Loose or bad connection
in the power supply to the
machine or in the electrical
system of the machine.
5. The cutter takes off too much
wood.
6. The feeding speed is too high.
1. Clean. If the motor is kept
clean it will be cooled more
efficiently.
2. Sharpen or replace the knives.
3. The electrical system may only
be opened by a qualified elec-
trician: Check that you have
the correct voltage on all pha-
ses and that the power cable
is correctly dimensioned.
4. The electrical system may
only be opened by a qualified
electrician: First of all, check
that the power cable has the
correct current and voltage
during operation. Also check
that all wires are correctly
connected in the electrical
system and in the motor of
the machine.
5. If the workpiece is too wide,
of a hard sort of wood or of
varying oversizes: Machine
the log in several steps and
just take off a little bit at a
time.
6. Lower the feeding speed.
Vibration or rumble in the cutter.
1. The moulding knives are
incorrectly installed.
2. The moulding knives or the
planing knives are incorrectly
sharpened.
3. Defect bearing.
4. Defect belt transmission.
1. Clean and install the knives
and the knife gibs/chip
breakers correctly. Identical
knives should be installed in
the same lateral position on
opposite sides of the cutter.
2. Sharpen the knives in pairs so
that they are identical on the
opposite sides of the cutter.
3. Clean the bearing housing
and replace the ball bearing.
4. Clean the belt pulleys and
replace the Poly V belt.
The machine table is difficult to
adjust in height.
1. The trapezoidal threaded
bars, on which the table is
suspended, are dirty and not
lubricated.
2. Faulty chain transmission.
3. The machine has been subject
to impact which has spoiled
the setting of the table.
1. Clean and lubricate the
trapezoidal threaded bars
with Super-flo.
2. Make sure that the chain runs
correctly on the sprockets.
Clean and lubricate the chain.
3. Adjust the table so that it lies
flat on all nuts.
