4. Safety Precautions:

a. Ensure unit is on a level ground (max, permissible sipping 5˚) to ensure proper lubrication.

b. Take care that the intake air is pure and free from obnoxious gases and exhaust lumens.

c. Ensure fitting hose are in satisfactory conditions, connecting threads faultiness.

d. Do not open disconnected fitting cocks when the compressor is running.

e. All repair works on the compressor unit must be carried out when the compressor is not running and the power source is switched off.

f. Never empty air tanks completely. The decanting tanks should always contain some residual pressure in order to avoid the entrance of humid ambient air.

5. Daily:

a. Check oil level – replenish or top up with Shell Emesis Oil SAE 30. b. General cleanliness of compressor. 6. Weekly:

a. Check oil level – top up with Shell Emesis Oil SAE 30.

b. V belt – flex should not exceed 3 mm.

c. Inspect the condition of the high pressure filling hoses and connections for 10 mins.

d. Running compressor by following the start and shut down procedures.

e. General cleanliness of the compressor. 7. Starting Procedure:

a. Ensure main switch is in OFF position.

b. Check oil level.

c. Switch on the power supply.

d. Record hours reading from timer (clock).

e. Open compensates drain cock so that engine starts without load.

f. Start the compressor to pressing the starter (green) button.

g. Once the compressor starts smoothly, close condensate drain cocks to allow pressure to build up.

8. Shut down Engine:

a. Ensure all filling cocks are closed. b. Depress ‘red button’ to stop the compressor. c. Switch off the main switch. d. Open condensate drain cocks to drain out trapped pressure and water vapor. e. General cleanliness and wipe off all condensation. f. Record timer reading and total running hours of the compressor. 9. Filling Procedures:

a. Ensure that the cylinders charged are the same at higher pressure rating than of the compressor.

38

b. Check the final pressure safety value by closing the filling cock, and let the compressor build-up pressure. (Final pressure on 3rd stage pressure safety value is set to work at 3000 psi (225 bars).

c. After the safety value has opened, fully open filling cock first (Otherwise loss of air through the venting bore) then open tank value.

d. Monitor the unit during filling operation. After reaching the filling pressure, always close valve prior to filling operation.

e. Due to automatic venting the latter, tanks can be disconnected without danger.

10. Maintenance:

a. Daily Inspection:

(1) Oil level check. (2) General cleanliness.

b. Weekly:

(1) Oil level check. (2) “V” belt tension – should not exceed 3 mm. (3) Ran the compressor 10 mins.

c. Operating Hours:

(1) Check “V” belt tension/flex. (2) Replace activated carbon cartridge.

d. 25 Operating Hours. Maintenance of intake filter, change position 4 times than change filter at 100 operating hours.

39

e. 50 Operating Hours. Check the security of coolers and belt guard.

f. 250 Operating Hours. Change oil (Shell Emesis SAE 30).

g. 400 – 600 Operating Hours. Maintenance of the suction and pressure valve,

only for 1st and 2nd stage, 3rd stage cannot be dismantled.

h. 1000 Operating Hours. Replace all suction and pressure valve spring.
