1.Cleaning the filter element
This filter is designed to clean air coming into the pump (Fig. 9). To ensure the pump continually receives a clean, cool, dry air supply this filter must always be clean and ventilation opening must always be free from obstructions.
WARNING: Never clean filter element with a flammable liquid or solvent.
CAUTION: Do not operate without the filter element.

2. Draining air tank:
Gradually open the drain valve, and drain out the air in the air tank. (Fig. 7)
Close tightly when drained.
3. Oil change-oil topping off
CAUTION: Overfilling with oil will cause premature compressor failure. Do not overfill.
(1)Within the first 50 hours of operation, completely replace the oil of the pumping element. Unfasten the pump oil plug on the casing cover, drain all the oil, and screw the plug back on (Refer to Fig. 1 and Fig. 10).

(2)Check the oil level of the pumping element daily.
(3)Change the oil every 200 working hours or every 3 months.
4.Belt tension
(1)Checking belt tension
(a)Allow unit to cool.
(b)Remove beltguard.
(c)Push down on belt midway between the two pulleys.
(d)Belt deflection should be about 1/4 inch.
(e)If belt tension is significantly greater than 1/4 inch, follow adjustment procedure.
(2)Adjusting belt tension
WARNING: Use caution when rolling belt onto flywheel as fingers can get caught between the belt and flywheel.
(a)Loosen the nuts on all four motor mounting bolts.
(b)Turn belt tensioner bolt at the front of the unit clockwise until 1/4 inch deflection is noticed between the pulleys.
