Boss Hydraulic Air Compressor BA435

1. Inspect the drive coupling for wear.

The air intake filter is a heavy-duty dry type high efficiency filter designed to protect the compressor from dust and foreign objects.

Frequency of maintenance of the filter depends on dust conditions at the operating site. The filter element must be serviced when clogged. A clogged air filter element will reduce compressor performance and cause premature wear of components.;

2. Check the cylinder head stud torque (see NOTE 2).

3. Check the operation of the receiver safety valves.;

Before adding or changing compressor oil, make sure that the compressor is completely relieved of pressure. Oil is added at the fill cap on a pipe on the rear of the crankcase. A drain line is located on the rear panel of the machine. The proper oil level is to the “FULL” line on the dipstick, when the unit is shut down and has had time to settle. The truck must be level when checking the oil. DO NOT OVERFILL. The oil capacity is given in “Compressor Specifications”.;

The interior of the oil cooler should be cleaned when the pressure drop across it at full flow exceeds 25 PSI.

2. Circulate a suitable solvent to dissolve and remove varnish and sludge.

3. Flush generously with hydraulic oil.

4. Once the cooler is reinstalled, fill the hydraulic system with the proper fluid to their appropriate levels.;
