Maintenance
Risk of serious injury if maintenance is neglected.
PH 260 is easy to maintain since most of the machine’s structure
is protected against rust. All cutter bearings and motors are
maintenance free. Necessary maintenance is set out below.
Ensure that the machine’s power supply has been
disconnected before opening the cover of the machine or
removing a protective cover.
Tip: Compressed air can be very useful for blowing the machine
clean each time you open the machine’s cover.
When the machine is being used:
- Clean the machine from wood debris. Especially ensure
that wood debris has not accumulated under the machine.
This can interfere with the cooling of the motors and lead to
a motor breakdown or, at worst, re. Furthermore, the belt
under cutter 4 can be sleckened if wood debris accumulates
under its motor.
- Make sure that all chip outlets are connected to the chip
extractor.
- Make sure that all feed rollers can move vertically.
- The machine table should regularly be cleaned and treated
with a lubricant, for example low-viscosity oil or wax.
Logosol’s Low Friction Agent (ref. no. 7500-001-5050) is
especially suited for wood processing machines. Avoid
getting lubricant on the feed rollers.
After each working session:
- Clean the machine from wood debris. Also check the chip
outlets and the hoses. Remove wood debris that has
accumulated under the machine.
- Clean the cutters and the feed rollers from resin and
accumulated wood debris. Use white spirit.
- Make sure that wood debris has not accumulated behind the
right side bearing housing of the upper cutter. If that is the
case, clean away the debris using a at tool, for instance a
metal ruler.
- Make sure that wood debris has not accumulated in the
springs under the bearing housings of the feed rollers. In that
case, clean them. Sometimes the spring has to be removed
from the threaded bar to be cleaned. Note the setting of the
spring before removing it.
- Clean the machine table and treat it with a lubricant (see
above, When the machine is being used).
- Clean and lubricate the three pressure rollers so that they
can move easily.
- Check the tension of the belts.
- Make sure that all screws and bolts are tight.
- Make sure that all cables and connections are in good
condition.
- Chack the lamps by pressing down the emergency stop
button and then the start button of the feeder.
Wood debris can accumulate under the spring mounted
bearings of the feed rollers. This impairs the feeding and
increases the risk of kickbacks.
Ensure that following parts are well lubricated. Preferably
use chain oil ISO VG 68:
- The bearings of the feed rollers and the springs.
- The trapezoidal threaded bars (32, 19), the chain (27) and
sprocket for height adjusting the table. (Also check the
tension of the chain, 41.)
- The carriage (44) of the movable cutter.
- The chain transmission (51, 53, 61) of the feed rollers.
- Knives, spacers, pressure rollers and side rollers (46, 68).
If the movable cutter is set in the same position for a longer
time (e.g. when producing long series of the same moulding)
it can get rusted up. Set the cutter so that it is in its outermost
and innermost position one or two times every month, and
lubricate the threaded bar of the crank and the bars of the
carriage.
If the machine is not being used during a long period of
time:
- Disconnect the power.
- Clean the entire machine extra thoroughly, and perform the
same maintenance as after each working session. DO not
forget the lubrication points.
- Remove knives, chip breakers and pressure rollers. Keep
these well lubricated and at room temperature.
- Cover the machine with a tarpaulin.
Other maintenance:
The out-feed roller, i.e. the rubber roller, will wear down and
should be replaced when it does not work as it should due to
wear and tear. Increased presence of out-feed marks on the
workpiece, or boards that are not being fed out of the machine,
can be signs of wear and tear on the out-feed roller.
