WARNING
Maintenance Tips:
1.There are two sides for the ball seat, both are chamfered, for one side worn, change to another side.
2.While changing the V-packings(both the upper and lower ones) for piston rod, please note that the convexity side shall be towards the piston rod,
then using rubber hammer to hit the flat side of the V-packings to fit the piston rod.
3. While fastening the screws for the pump block, please do not fasten one screw to maximum and then fasten the other one, the correct action is to
fasten one screw to 90% depth first and then fasten the other screw to maximum and later fasten the first screw to maximum.
4.There is one washing piece inside the pressure sensor, normally the washer won’t be broken, but it can not be left out.
5. After changing the upper V-packings, the nut shall be fully tightened by using a bench clamp.
6. Before starting up a new airless piston pump, please double check the two screws for the pump block and make sure that they are fully fastened.
Same checking after changing new V-packings.As the V-packings are made of high polymer material,after being stocked or used for some time, they
could somehow expand.
7. It’s critically important to turn on the PRIME VALVE before spraying or after changing the paint bucket, if air happens to enter into the piston pump
system and you forget turn on the PRIME VALVE before spraying, it will do big damage to the machine system itself, as the compression ratio for paint
coatings and for air are different.
8.The positive pole and negative pole for the motor can not be connected reversely via the carbon brush,if connected reversely, then the motor will turn
reversely,if the machine runs this way for some time, the motor be become demagnetized. (*For model X20 only)
9. If the V-packings are broken, then there will be paint coatings leakage, please change V-packings immediately, otherwise, the paint coatings may
enter into the gear box to damage the whole gear box.
10. While turning the pressure knob to adjust pressure,please do not turn the knob too hard,as the electric parts inside the knob could be damaged
due to too hard turning.
11.There is micro switch in every airless pump with mechanical pressure control system, and the fixing screw of the micro switch is set properly
before shipment, please do not try to change the position of the fixing screw, otherwise, the micro switch may not work properly.(For X20 model only)
12. One quick tip to identify if the ball seat is good or not, after turning the PRIME VALVE back to spraying position, please open the front cover, if the
connection rod stays on the upper position, then the ball inside the piston rod is somehow damaged, if the connection rod stays on the lower position,
then the ball seat is somehow damaged.
13. If the airless piston pump is not fully cleaned after spraying, the drywall coatings may stop the pressure sensor from working properly, so the airless
piston pump shall be fully cleaned after spraying.
14. If the fuse is burned due to over voltage, please check the capacitor first to see if it’s in good condition, if yes, then please further check the bridge
rectifier with a universal meter.
15.One quick tip to check the pressure control board for airless piston pumps with mechanical pressure control system, first step is to turn on the
PRIME VALVE, then stick to the micro switch with a screw driver, if the machine could stop, means no problem for the pressure control board.
16.If the airless pump is equipped with manifold filter, then the filter shall be often cleaned after spraying,once per day is recommended, or at least
once per week, if the filter is totally stuck by drywall coatings, then the electric board and pressure sensor could be burned, under this situation, fuse
could not protect the electronical board and pressure sensor.
17. As a reminder, for big airless piston pump with big flow rate(mainly refers to X45 and X52/X52L), please do not use short high pressure hose like
3m or 5m, as it might cause serious motor damage. Cleaning the machine, parts every time after finished the paint work.
18.Tips need to replace after 4000 – 5000 m2 depending on abrasiveness of paint.
19.The Piston rod/V-packing and sintered carbide ball need to replace after about 200 hours spraying, Especially when the pressure goes down,
or difficult to draw in paint.
20.For the permanent magnet DC motor, the carbon brush need to replace after 1500 hours, otherwise, the motor will be damaged.
21.Please check every parts had been screwed on the machine very tightly before using machine.
22.If the machine need to be storage over 10 days, Do run the machine with lubricating oil thoroughly, for rust protection or any stuck inside the
pump .(check the details in CLEAN UP)
23.For the maintenance of the fluid pump, do strictly in accordance with the instructions, and screw tightly.(check the details in Service)
24.Please read the manual or contact the distributor if any problems with the machine, DO NOT take the machine to pieces without professional staff.
