Read and comply with these original instructions prior to the initial operation of the machine. Before first start-up it is necessary to read the operating instructions and safety indications.

Machine Start Up

➔ Connect water supply hose to the water inlet of machine

➔ Connect the high-pressure hose with the trigger gun to the outlet fitting of the machine. (use only original hose supplied by ASEA Marine)

➔ Turn on the water supply (Ensure sufficient water supply with a minimum inlet pressure of 2bar and 20 l/min)

➔ Plug in main power supply and switched it on**

➔ Pressed the start button on the electrical panel box

➔ Pressed lever on the trigger handle, and you can begin operating with your machine.

**Note: When you switched on the mains and the red Led light on the starter panel box is on, it means the water supply pressure (min 1 bar and above) is weak, and you will not be able to turn on the machine for safety reason. Please try other water supply source with higher pressure.

**First oil change after 50 operating hours, further oil changes after every 500 operating hours. (recommended oil SAE 10/40W).
