Operation
5.1
General
The pump must not be operated in dry running mode (without water supply)!
The pump may be operated for max. 5 minutes with lance/jet nozzle in continuous operation,
without water discharge.
In order to avoid damage to the unit (EC-60), the water feed temperature must not exceed 40°
C.
The feed water from the piping system must be filtered with 300-400 µ. The water pressure
must not exceed 10 bar. Minimum water pressure 0.3 bar (at volume flow of 20 l/min),
otherwise no function of the motor.
If feed water is taken from a well or open water, it must be filtered with 100-200µ.
Do not drive the device over uneven terrain/overhanging objects! Rotation arm/nozzles can be
damaged/adjusted!
It is generally prohibited to reach under rotating parts - risk of injury!
1.
Fold out the device bracket.
2.
Turn on main valve (Fig. 1A/Fig. 1)
Important: It is essential to open the water
supply (main tap) before starting the
motor! (Fig. 1a/Fig. 1)
Always close the cross flushing (Fig. 4)
during the starting process.
If the engine has difficulty starting (often in cold
weather), turn the pressure adjustment valve () out
(counterclockwise). Once the engine is at operating
temperature, turn the pressure adjustment valve ()
back in (clockwise). (Figure 1B) →
