damaged.
4.2
Water intake line breathes
causing pump cavitation.
4.3

TROUBLESHOOTING
2.1
Adjust the hydraulic flow to the demanded
level at required pressure.
2.2
Verify the nozzle sizing and replace with
proper one.
2.3
Verify the hose sizing and replace with proper
one.
3.1
Adjust the hydraulic pressure to the
demanded level at required hydraulic oil flow.
Pressure loss should be minimized - do not use
hoses of too small diameter or/and of an
excessive length.
3.2
Verify the nozzle sizing and replace with a
proper one.
3.3
Replace the nozzle.
3.4
Check and fix the problem. Use pressurised
water supply if available.
3.5
Check and re-adjust to specification.
4.1
Check water valves, clean thoroughly or
repair.
4.2
Check water intake line and fix the problem.
4.3
Verify the hose sizing and replace with proper
one.
4.4
Adjust the hydraulic flow to the demanded
level.
