8.2.1 Cooling System
The cooling air must be able to circulate freely.
•
Check the cooling air inlet/outlet openings every week, and if necessary, remove and clean any dirt and dust deposits.
For maximum cooling effectiveness, the air must be able to circulate unhindered. Dirt impairs the cooling effect and
can cause the machine to overheat and fail!
8.2.2 Compressor/Vacuum Pump
•
The machine must be cleaned weekly.
Washing or rinsing with high-pressure water jets may result in water penetration, which can cause failure of the
compressor/vacuum pump.
•
Carefully clean/remove any dirt on the oil tank.
•
After wet cleaning the machine should be run warm for a few minutes to prevent the rotor vanes from sticking.
8.2.3 Vacuum Filter
Clean the filter daily or at least once a week, depending on the amount of dirt.
When the ventilation valve activates, the vacuum filter should always be cleaned.
The filter element consists of a stainless steel mesh.
