CRANKCASE OIL. Check the oil level weekly and refill to overflow with oil recoin-
mended in Table 5-2. Drain and replace the crankcase oil at 500 hour intervals.
When changing oil, never use kerosene or gasoline to flush out
the crankcase. The use of flammable cleaning agents is dan-
gerous and is absolutely prohibited. Use a regular flushing oil
for this purpose.
AIR INLET FILTER SILENCER. It is very important that the air inlet filter silencer
3-8.
be kept clean at all times. A dirty inlet filter silencer reduces the capacity of the compressor
and may allow induction of dirt particles which will rapidly accelerate wear of internal parts.
Remove and clean the filter pads once a month (more often in dusty conditions). The pads
should be replaced at 1000 hour intervals. As dirt collects on the outside of the filter silencer
the outside surfaces should be brushed.
We recommend the use of safety solvent for cleaning. Never
use kerosene, gasoline or similar flammable fluids to clean the
air inlet filter silencer.
