16.0 Maintenance.
The
KSM-Stoker Tuxedo
is constructed in a way so as to minimize the maintenance as much as
possible; however there are a few things that call for your attention.
16.1 Oxygen sensor.
The oxygen sensor is mounted in the top of the smoke box back the boiler. The oxygen measurements are
vital to ensure a good combustion which is why the correct measure is important.
The oxygen sensor should be dismounted and cleaned minimum once pro year when the overhaul is
made.
If you experience that the measures are incorrect between the yearly overhauls, you then should dismount
and clean it carefully with a steel brush and compressor air.
To check the oxygen sensor, leave it in fresh air and check if the oxygen value is 20-21 %. If it is not it is
possible to calibrate it. To do so please enter the menu “SERVICE” “calibrate sensor” and press
“MENU”.
IMPORTANT: The oxygen sensor has to be in fresh air with the steering sensor for minimum five
minutes before calibrating.
If the oxygen sensor still does not show the correct value 20-21 %, you probably have to change it.
16.2 Gear.
From the factory, the strong gear has been filled with lubricant and this needs no topping up. However,
pay attention if oil spots appear on the floor that might originate from the gear. In that case, contact your
plant supplier.
16.3 Fire Protection.
Once a year, turn off the small tap on the pressure tank and then dismount the tube on the thermal valve.
Direct the tube into a bucket and open the tap. After this, dismount the thermal valve and clean away old
sawdust from the hole leading into the screw.
After flushing and cleaning, re-screw the tube and the valve – don’t forget to turn on the water tap again.
16.4 Air Nozzles.
Before starting up a new heating season, make sure that the air nozzles have not burnt and are broken. If
the nozzles are not absolutely in order, the result will be a poor combustion.
The nozzles shall be remounted with some heat-proof gun gum, as described in section 12.
16.5 Screw Tube.
As occasion requires, clean this tube for clinker once or twice during each heating season, in the area
where the tube runs into the burner head.
Be particularly careful to remove any clinker in the corners seeing that this may otherwise prevent the
fuel from moving forward and will thus block the screw.
16.6 Firebricks.
You may be unlucky enough to break the firebricks if you handle them to roughly while they are still
warm. It is easy to exchange the broken bricks, always use firebricks supplied by KSM to be sure to get
the correct quality.
