2. Check whether the lubricant is clean or not. It should be replaced with new one if itbecomes turbid.★ Steps for the replacement of the lubricant: Turn on the pumpand run it for 30 min. to reduce oil viscosity → Turn off the pump → Open(5) oil drain plug and drain the waste oil → Open (4) air inlet → run thepump for 1-2 min. to clean up the remaining waste oil in the pump → close(5) oil drain plug → Add new lubricant up to the proper level → Screw on (2)oil filler cap.★Ensure to dispose of the drained oil in compliance with localenvironmental regulations.3. Ensure that the whole inlet system is well connected and without leakage then press(1) power on/off to start the pump.4. Press (1) power on/off to turn off the pump after the operation is finished.★ Please make sure to release the pressure before turning off thepump to prevent oil from being sucked reversely.★Please remove the power plug from the power outlet if not inuse promptly to save power.G. Basic Troubleshooting1. Failure to start:Check if the input voltage is within + or (-) 10%. The improper input voltage willcause a failure to start.2. Oil leakage:2.1 Ensure that the leaking oil is not the residues of oil.2.2 It may need to replace washer or O-ring of the tanker with new ones. If itleaks at (5) oil drain plug then wrap the seal tape on it.3. Insufficie nt Vacuum:3.1 Check if the lubricant is clean and replace the new lubricant by following“Steps for the replacement of the lubricant” mentioned above.3.2 Check if the current oil level is within the proper level position. Do not keepthe current oil level at a higher position; as the pump starts to run, theoperating temperature can inflate the lubricant and make the oil level higherthan Max. line. Whenever checking the current oil level position through (3) oillevel window, always make sure to shut (4) air inlet and start the pump. If theoil is short, please add it immediately.3.3 Check the whole pipe system to see if all are connected tightly.
