Waterous Arizona Operations 500-100 & 120-P Operations Rev 1Page 9 of 30SECTION 3. SYSTEM SERVICE AND MAINTENANCEExcessive heat build-up and oil system contamination are most common causes ofcompressor system problems and premature wear. With proper operation and maintenance,the compressor system should far outlast the vehicle it is mounted on. Adherence to thefollowing guidelines will prevent potentially costly damage.1. There is a sight gauge provided on the oil reservoir and visible through a hole on thepump panel. The oil level should be at approximately halfway up the window. Cheek theoil on level ground, prior to system start up. If the system has recently been run, wait 10minutes after shutdown for the oil to stabilize before checking the oil level. The oil shouldbe checked daily or before or after every use. The compressor uses common hydraulicoil. This oil is classified by an ISO standard as ISO 68 viscosity and is sold under varioustrade names. Many are sold as in “anti wear” hydraulic oil and area available from autoparts or lubricating oil suppliers.2. The oil should be changed after the first 30 hours of system operation. After that, the oilshould be changed annually. There is a drain plug located at the bottom of the sump. Theoil 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. The spin-on filter cartridge is a Mann-Hummel hydraulic oil filter.4. Run the compressor for 2 minutes after changing the oil, then re-cheek the oil level andadd oil as necessary. DO NOT OVERFILL.5. Visually inspect the compressor oil system weekly for signs of leaks. Check the aircompressor Poly Chain drive for proper tension and signs of wear monthly or morefrequently as dictated by the amount of use.6. Proper tension on the Poly Chain is to a no slack setting or slightly loose (about 3/8” - If indoubt, do not tighten the Poly Chain). A slightly loose Poly Chain is acceptable. An over-tightened Poly Chain may cause equipment failure, and may void the product warranty.7. Inspect the compressor air intake filter and clean or replace as necessary. Theenvironment in which the unit operates will determine the frequency of air filter serviceand replacement. In any situation, replace no less frequently than yearly.8. Replace the oil / air separator cartridge every 24 months, or if the unit’s oil consumptionsuddenly increases. A sudden increase may be caused by a hole in the internal media ofthe cartridge allowing oil to carry through and discharge with the compressed air.9. Completely drain the water from the compressor oil cooler in cold weather to preventfreeze damage. |
