Bleeding air from the circuit
The symptoms of air in the circuit are as follows:
-
The pressure varies rapidly and with amplitudes greater than ± 0.5 bar | 7.25 psi.
-
Abnormal machine vibrations occur.
When air is present in the system, the pump must be primed. The main causes of air in the system are as follows:
-
The pump has been switched off for a long time.
-
The suction filter has been opened.
-
The selected tank is empty and the pump is switched on.
Checking nozzle orientation
The nozzle angle should be 8°.
Refer to chapter Nozzle check.
If a nozzle needs adjusting, do not do it yourself as this could upset the solenoid valve. Contact your dealer.
To prime the pump:
-
Make sure the pump is switched off.
-
Position the valves:
-
Valve A : position 2
-
Valve B : position 4
-
Valve C : position 5
-
Valve D : position 100%
-
Engage the pump.
-
Wait for the pressure to stabilize.
-
If the pressure does not stabilize, check that there are no leaks and ensure that the liquid level in the selected tank is sufficient.
-
To adjust the working pressure, refer to chapter Adjusting the working pressure.
Lead-acid battery maintenance
WARNING
Before working on the battery terminals, switch off the machine and take precautions to prevent short circuits. Avoid contact between tools and conductive parts that could bridge the battery terminals. Follow the battery manufacturer's safety instructions.
It is recommended to clean the battery casing and terminals once a year.
-
Clean the battery casing with a dry or slightly damp cloth.
-
Clean the terminals with a dry cloth. If necessary, use a suitable scraper or wire brush to remove corrosion and oxidation deposits.
-
After cleaning, apply a specialized anti-oxidation dielectric grease suitable for battery terminals.
