GLOSSARY (con't.) where applicable. CUT-OUT PRESSURE: When you start your air compressor, it begins to run, air pressure in the tank begins to build. It builds to a certain pressure before the engine automatically idles down - protecting your air tank from pressure higher than its design rating. The pressure at which the engine idles down is called "cut-out pressure". DUTY CYCLE All Makita manufactured air compressors are recommended to be operated on not more than a 50% duty cycle.
DESCRIPTION OF OPERATION (con't) AIR INTAKE FILTER: This filter is designed to clean air coming into the compressor pump. This filter must always be clean and free from obstructions. See "Maintenance". AIR COMPRESSOR PUMP: To compress air, the pistons move up and down in the cylinder. On the down stroke, air is drawn in through the air intake valve. The exhaust valve remains closed. On the upstroke of the piston, air is compressed.
INSTALLATION AND BREAK-IN PROCEDURES (con't.) Initial Start Up Procedure: 1. Check engine & pump oil. 2. Open the air receiver's drain valve. 3. Run the compressor for a minimum of of twenty (20) minutes in the no-load condition to seat the piston ring. 4. Close air receiver drain valve. Your compressor is now ready for use. Piping Plastic or PVC pipe is not designed for use with compressed air. Regardless of its indicated pressure rating, plastic pipe can burst from air pressure.
OPERATING PROCEDURES FILLING THE COMPRESSOR WITH OIL BEFORE OPERATING THE AIR COMPRESSOR 1) Remove the oil filler plug PLEASE CHECK THE FOLLOWING CAREFULLY: 1) Check to see that nuts and bolts are all snug. 2) Check if the quantity and quality of oil is correct. 3) If the intake filters are dirty, they should be replaced or cleaned.
OPERATING PROCEDURES CHECKING BELT TENSION Adjust belt(s) so when pressure is applied at the center, there is approximately 1/2" slack (see diagram "Figure A" below). If the belt is installed too tight, the engine might be overloaded. This will cause the engine to overheat. If the belt is installed too loosely, it will slip and excessive wear and vibration will occur. HOW TO INSTALL A NEW BELT IF REQUIRED: 1) Turn off engine. Wait until engine is completely stopped. 2) Remove belt guard.
EXTRA CARE SHOULD BE TAKEN TO AVOID PERSONAL INJURIES WITH AUTOMATICALLY CONTROLLED COMPRESSORS MAINTENANCE SCHEDULE DAILY OR BEFORE EACH USE 1) Check oil level 2) Drain condensation from air receiver 3) Check for any unusual noise or vibration 4) Be sure all nuts and bolts are tight WEEKLY 1) Turn off engine. Clean dust and foreign matter from cylinder head, engine, fan blades, intercooler, and air receiver.
