Oil Maintenance; Air Filter Maintenance - Central Pneumatic 67847 Owner's Manual And Safety Instructions

Oil Maintenance

Check the oil periodically for clarity. Replace oil if it appears milky or if debris is present,
or every 6 months, or 100 hours of runtime, whichever comes first.
In harsh environments such as high heat or high humidity, you will need to replace the oil more frequently.
CAUTION! TO PREVENT INJURY FROM BURNS:
Allow Air Compressor to cool before changing the oil.
1. Place a container under the Drain Plug.
2. Remove the Oil Breather Plug to
allow air flow into the Pump.
3. Remove the Drain Plug, allowing the
oil to drain into the container.
4. When the oil is completely drained from the Pump,
replace the Drain Plug.
Draining Moisture from the Tank
The Drain Valve is located under the Tank.
It must be used daily to release all trapped air
and moisture from the Tank. This will eliminate
condensation which can cause tank corrosion.
CAUTION! Do not open the Drain Valve so
that more than four threads are showing.
1. Turn the Power switch of the compressor off.
2. Place a collection pan under the Drain Valve.
3. Unthread the Drain Valve two or three turns ONLY.
4. When all the pressure and moisture is released,
close the Drain Valve.

Air Filter Maintenance

Check the Air Filter weekly to see if it needs replacement.
If working in dirty environments, you may need to replace the filter more often.
1. Remove the Cover.
2. Remove the Air Filter.
