Page 8: Caution During Operation
1.Safety Caution during Operation Do not replenish compressor oil during operation Do not, under any circumstance, open the oil filler cap of separator receiver tank while running or immediately after stopping operation. It is very dangerous because the oil filler cap could be blown off and high temperature compressed air and oil could jet out from the filler port, and cause serious injury. - Page 9 1.Safety Operation with compressed air supply port opened is prohibited Do not operate the machine with service valves and relief valve open unless air hoses and/or pipes are connected. High-pressurized air blows out and its air pressure could cause injury to the people nearby. When the machine has to be unavoidably temporarily operated with its port open, be sure to mount a silencer to reduce noise and wear protective materials such as...

Page 10: Caution During Inspection And Maintenance
1.Safety Caution during Inspection and Maintenance Hang a “Now Checking and under Maintenance” tag Remove the starter key from the starter switch before starting inspection, and hang up a “Now Checking and under Maintenance” tag where it can be easily seen. The checker must keep the key during checking and maintenance. - Page 11 1.Safety Adjusting tension of fan belt Be sure to stop the engine and remove the starter key whenever the tension of the fan belt is to be adjusted. Remove the negative (–) side cable from the battery. If the machine is running, it might catch the operator’s hand into the fan belts, and this could cause a serious injury.
- Page 12 1.Safety Opening coolant water drain valve cap Be sure to stop the engine, and let the coolant water sufficiently cool down before draining it. If the drain valve is opened before the coolant water is cooled enough, hot water could jet out, and it could cause scalding.

Be sure to change the oil completely at every scheduled interval. Follow the designated regulations to dispose of compressor oil. ＊Unit is delivered ex. factory, filled with “AIRMAN OIL LONG LIFE HP”. - Page 27 4. Operation 4.4.3 Coolant Quality of coolant and antifreeze Use soft water of good quality such as tap water for coolant. When water with dirt, sand, and/or dust contained, or hard water such as well water (ground water) is used, this will cause deposits inside radiator or on cylinder head, and will cause engine overheat due to poor flow of coolant.

Page 28: Check Before Starting Unit
4. Operation Check before Starting Unit Check before starting unit Be sure to check the unit before operation. When any abnormality is found, be sure to repair it before restarting the unit. Be sure to make daily checks before operation. If the unit is operated without prior check and without noticing its abnormality, such operation could cause seizure of components or may even cause fire. - Page 29 4. Operation 4.5.2 Check Coolant Level Taking off the radiator cap Be sure to stop the machine and allow time to cool. Then loosen the radiator cap one notch. After the coolant water is sufficiently cooled and the inner pressure is released, take the cap off. If this procedure is neglected, the inner pressure can blow off the cap.
- Page 30 4. Operation 4.5.3 Check Compressor Oil Level Refilling of compressor oil When you refill the separator receiver tank with compressor oil, stop the engine, and make sure that the pressure gauge indicates 0MPa and there is no residual pressure in it, and then gradually loosen the oil filler cap for refilling oil.
- Page 31 4. Operation 4.5.5 Check Fuel Check fuel level gauge before operation. Replenish enough fuel to prevent fuel shortage during operation, if the level is low. Drain condensed water accumulated at the bottom of fuel tank whenever it becomes necessary. Fire prevention Do not, under any circumstance, smoke cigarettes or light matches during fueling.

- Page 33 4. Operation 4.6.1 Procedure to Start the Unit Be sure to warm-up Be sure to let unit warm-up after starting for smooth operation of the engine and the compressor. Do not operate the engine at full load immediately after it starts up. This will shorten the equipment life. During the warm-up operation, examine the different parts of the equipment for any looseness, leakage of water, oil, fuel, and other irregularities.
- Page 34 4. Operation 4.6.2 Operating Procedures when Engine Fails to Start up on First Attempt When the engine fails to start up even after performing the startup procedures ① to ⑥ do not keep the starter running, but set the starter switch back to ”STOP” and wait about 30 seconds. Then, repeat the startup procedure once again.
- Page 35 4. Operation 4.6.3 How to Start the Unit at Low Temperature Operation under Cold Weather Conditions below -5°C Use SAE10W-30 (CD class) for the engine oil. Use LLC (antifreeze). Use correct amount to provide freeze protection, according to the ambient temperature.
- Page 36 4. Operation 4.6.4 Gauge Indication while Operating During operation, keep the discharge air pressure gauge indicating higher pressure. than 1.37MPa (for PDSH850S/PDSJ750S) Continuing equipment operation at a lower pressure than the above pressure may cause overheating, since it affects the separation of lubricating oil inside the oil separator and reduces the oil flow to the compressor air-end, resulting in temperature rise.
