Safety
Pressure vessels (air receivers) are a type of plant, and as
such, MAY be required to be registered with the relevant
statutory authority in your state. Regulations regarding plant
registration vary from state to state. Check with your relevant
government authority about plant registration.
Compressed air can be dangerous. Never point compressed
air tools or equipment towards another person.
After use, drain all residual air pressure or engage outlet tap
to prevent accidental discharge by children.
Keep clear of compressor pump during and after
operation. Heat build up in the pump may cause burns to
unwary.
Never operate the unit without factory fitted belt guard.
(Belt Drive Models) or Pump Shroud (Direct Drive
Models).
Never operate the unit with damaged or exposed
electrical wiring.

Commissioning and Operation
When commissioning a new compressor or re-commissioning a compressor which has been out of
service, the following operation recommendations should be followed.(The operator should have
experience and be qualified.)
1. COMMISSIONING
A. PRIMARY CHECKS
1. Confirm that all the pipe and wire connections have been firmly connected, and the main
power should be turned off.
2. Make sure all the electrical connections are correct.
3. Check the belts for tightness and adjust if required.
4. Remove the RED FICED PLATE.
5. Open the Stop Valve and switch on the main power.
B. CHECK BEFORE RUNNING
1. Confirm that the main Power Source and Earth have been connected well and the 3-
phase voltage is correct.
2. (2) Press the START button and check rotation of Air end. The correct rotation is CCW
looking from Air end pulley side(Follow the arrow label). If rotation is correct, go next
process. If the Air end rotate in wrong direction, STOP immediately and exchange any
two cables of power source.
ATTENTION: Incorrection direction of rotation is not allowable or the Air end will
damaged seriously.
C. CHECK UNDER RUNNING
1. Switch power ON, press START.
2. Press STOP and CHECK immediately while there are noise or the vibrations of unit is
getting seriously.
3. Check pressure is rising or not. If pressure does not rise, turn the unit off, check the
Pressure Gauge, rotation of Air end and pressure pipe.
4. If the unit is running in normal status, close all the covers.

Maintenance
BELT MAINTENANCE
ADJUSTMENT BELT TENSION
1. Loosen the two fixed bolts on the side of common seat.
2. Screwing the adjustment bolt(lower) downward, and the motor seat goes down
slowly until the belts reach the proper tension(see page 20).
3. Tighten the adjustment bolt(upper). Check the belt tension again then tighten the
two fixed bolts on the side of common seat.
BELT REPLACEMENT
1. Loosen the two fixed bolts on the side of common seat.
2. Loosen the adjustment bolt (upper), and then screwing the adjustment bolt (lower)
upward. The motor seat goes up slowly until the belts can be take off.
3. Make alignment by locating a steel ruler between pully of Air end and motor, and
the clearance between two pulley below 1.0 mm.
4. Replace all belts.
5. Follow steps A. (ADJUSTMENT BELT TENSION), C. (BELT TENSION
