6.3 Description daily control

6.3.1. Frame

Check the frame in its entirety at loose bolts and/or cracks of the welds.
Keep the machine as much as possible clean to prevent act on dirt, water, oil and messed fuel.

6.3.2. Valves + manometer

At an switched off machine, this means a halted engine, the manometer must reflect 0 bar.
At an maximum performing machine, this means operated at full load working engine, the manometer can
not indicate more than the maximum pressure by DiBO indicated, for your machine.
After operation and releasing the gun can still remain a small pressure remainder present.
The reflected value of the manometer must be between 0-30 bar, the valves are then all right.

6.3.3. High pressure pump

Check the pump on loose connections, bolts, seals and leaks.
Puts the machine on a horizontal base.
The oil level must stand halfway the level glass.
Take at doubt the oil level stick separately, where the oil level must stand between both mark lines.
If pump oil gives a milky impression, frequently indicates this on an internal leak as a result of which water
touched oil there.
Immediately repair by a DiBO technician is necessary then.

6.3.4. High pressure- and low pressure part

Check the hoses, piping and connections on external damages and leaks.
If damaged or leaks these must be immediately replaced.

6.3.5. Spray tools

Check lances and guns on leaks, external damages and hair cracks.
If damaged or leaks these must be immediately replaced.
Check the spray image of the water jet, if these blows out to much you must replace the nozzle.
Check protective cap-nozzle on damages and replace if necessary.
Check the thread of the couplings on external damages. At damage let these replace without delay.

6.3.6. Electrical part

Checks visible electric wiring and components (among other things switches) on external visible damages.
If damaged let replace the concerning parts.

6.3.7. Water tank

Check the water tank on external damages and leaks.
Check when the tank is filling if the float system works properly.

6.3.8. Vibration dampers

The vibration damper is situated on the top of the high pressure pump (not always present).
The damper takes care that the vibrations of the water will be skimmed.
Check the working pressure on the vibration damper.
The working pressure has to be 60 %.
Consult a DiBO- technician at malfunctioning of the vibration damper and for further maintenance.
