SECTION 3. SYSTEM SERVICE AND MAINTENANCE

Excessive heat build-up and oil system contamination are the most common causes of compressor system
problems and premature wear. With proper operation and maintenance, the compressor system should far
outlast the vehicle it is mounted on. Adherence to the following guidelines will prevent potentially costly
damage.
1. There is a sight gauge provided on the oil reservoir/sump. The oil level should be at approximately
halfway up the window. Check the oil on level ground, prior to system start up. If the system has
recently been run, wait 10 minutes after shutdown for the oil to stabilize before checking the oil level.
The compressor uses common hydraulic oil. This oil is classified by an ISO standard as ISO 68
viscosity and is sold under various trade names. Many are sold as "anti wear" hydraulic oil and are
available from auto parts or lubricating oil suppliers.
2. The oil should be changed after the first 30 hours of system operation. After that, the oil should be
changed annually. There is a drain plug located at the bottom of the sump. The oil fill cap is located on
top of the unit.
3. Change the compressor system oil filter at the same time as the oil is changed. Call Waterous for
replacement elements.
4. Run the compressor for 2 minutes after changing the oil, then re-check the oil level and add oil as
necessary. DO NOT OVERFILL.
5. Visually inspect the compressor oil system weekly for signs of leaks. Check the air compressor Poly
Chain drive for proper tension and signs of wear monthly or more frequently as dictated by the amount
of use.
6. Inspect the compressor air intake filter and clean or replace as necessary. The environment in which
the unit operates will determine the frequency of air filter service and replacement. In any situation,
replace no less frequently than yearly.
7. Replace the oil / air separator cartridge every 24 months, or if the unit's oil consumption suddenly
increases. A sudden increase may be caused by a hole in the internal media of the cartridge allowing
oil to carry through and discharge with the compressed air. Call Waterous for replacement separator
cartridges.
8. Completely drain the water from the compressor oil cooler in cold weather to prevent freeze damage.
