MAINTENANCE
To prevent clogging which will put the pump under strain, clean the Spray Lance nozzle
often using the following steps:
1. Switch OFF the machine and disconnect the Spray Lance
2. Use the Cleaning Tool to clean the Spray Lance Nozzle (Fig. 13)
3. Flush the nozzle backwards with water
The machine air vents should be kept clean and free from blockages to let air pass
through freely.
The couplings should be greased regularly to ensure an easy connection and that the
O-rings do not dry up.
