Some Quick Self-Maintenance tips:

Gun Maintenance 

Powder hose

Powder Hoses can get run over, cut, pinched and damaged. So it is important to keep an extra replacement powder hose.  The Gema powder hose has a conductive strip, so a broken hose must be replaced. If you only have two or three main colours, there is an advantage to having an extra hose for quick colour change & to save time and avoid contamination. Hoses also need  hose connectors for the gun side & the injector side



the most common wear part is the insert sleeve (Venturi ). As the powder is propelled through the injector the insert will get worn from the inside and sometimes even cut grooves. If it goes on for too long, the injector becomes less efficient & the gun will surge. Before that happens we suggest you check the sleeve every time you do a colour change or before you start a new job. The insert /venturi is a very inexpensive spare part which will make a big difference to your final product.


The last wear part is the flat jet nozzle at the tip of the gun. With a lot of powder use, the nozzle & electrode holder will wear off. If the gun is drooped, most likely it will land on the tip & can damage the nozzle & might also break the electrode holder.

Keeping spare genuine Gema parts at your fingertips will prevent lengthy production delays due to simple issues. If your budget allows a spare manual gun is always good to have as a backup.
