4.4 Shutdown procedure

 

On compressors using gasoline drive, close hand lever on carburetor and turn "On/Off" switch off. 
Close fuel cylinder valve and drain condensate out of compressor. In addition, check oil level of 
compressor, gasoline level in engine tank and carry out current service (§ 4.8). 

 

4.5 Preparation for extended storage

 

Prior to extended storage, the compressor should run a few minutes against a small backpressure of 
approximately 300PSI (20 bar), by partly closing filling valve in order to prevent possibility of corrosion. 
Open condensate drain valve again, then close them to prevent loss during transportation. 

 

4.6 Preservation of compressor

 

Remove intake air filter cartridge. Start compressor and slowly fill 10 to 20 cm3 of MAXLUBE 501 
synthetic oil into intake piece of compressor. Keep filling valve open and condensate drain valve 
closed. Operate unit for approximately 1 minute. Close filling valves and open condensate drain valves. 
Decompress all stages and then close all valves. 

In cases of prolonged storage periods, run unit every 3 months. Lubricating oil loses its efficiency 
during prolonged idle periods in the compressor and motor. This requires draining and replacing with 
fresh oil at least once a year. 

 

4.7 Maintenance and air tightness test

 

Besides the standard stipulated service works (§ 4.8) we recommend you clean the compressor at 
regular intervals to notice any oil leakage and impairment to the efficiency of the cooling system 
resulting from dirt on cooler coils and fins. Test air tightness by regularly brushing all fittings, valves and 
tubing of the condensate drain with soap-water or with leak test spray. 
Air leaks considerably impair the output of the compressor. 

 

4.8 Service, service timetable 

 

4.8.1 Oil level check, change of oil

 

Check oil level daily before putting the unit into operation. Oil level must be between minimum and 
maximum of transparent tube on the crankcase, behind the filter or on the front, oil level sight glass for 
cabinet models.  Oil level must not be too high because excessive oil can result in over-lubrication and 
coking of the valves. When oil level is too low, oil thrower pins do not any longer dip into oil, lubrication 
stops and the unit is destroyed. 

Oil change:

 first oil change after 15 operating hours, further oil changes every 50 operating hours. If 

the operating hours indicated above are not reached within 5 months, oil must be changed after the 
season or before storing for the winter. Do not use oils of different brands at the same time: do not use 
openly stored oil, but only from original oilcans.
