When using the self-priming water supply mechanism:
Make sure the water inside the supply contained is placed as high as possible, when compared to the water
supply into the pump. Higher elevation difference of water levels helps to simplify the priming and reduce
cavitation - the phenomenon associated with release of air bubbles from the liquid. That may happen inside the
pump, if the vacuum at the inlet is too high - impaired priming. There is a risk of damage to the pump.
That is why the priming hose should have the largest diameter possible and it must be
the shortest possible. Follow the methods defined on page 3 to bleed to priming pipe.
Use of self-priming cleaning agent
The pump has a function for automatic drawing of the cleaning agent
from its supply contained using vacuum. The use of this function requires
extra nozzle for cleaning agent application (item No.:
ASBS0-N0065)
.
The pump will start drawing the cleaning agent through the opening
marked with an arrow, only when this nozzle is used. Link the cleaning
agent supply hose to the flange marked with an arrow (close to the high-
pressure pump adaptor) and dip the other end with the screen into the
contained with diluted cleaning agent. Press the gun trigger to apply the
cleaning agent.
This configuration is not designed for
production of active foam.
Should you wish to use the active
foam, you need to purchase the foam generator (item No.:
SP000-
FL001).
Pump storage for winter season
Storing the pump in areas with the ambient temperature below the freezing point may
result in irreversible damage to internal components, if not drained properly!
Excess water draining procedure:
Make sure the engine switch (p. 4 pos. C) is in the
OFF position.
Disconnect the supply hoses from the pump. Grasp the starter cord grip and pull the cord
5 times,
as if you
were starting the engine. This action will help the water drain out of the pump through the high-pressure opening.
It is not recommended to store the pump in areas with the ambient temperature dropping below the freezing
point, since a significant change of outside temperature may result in condensation of water vapour even in
areas regularly not affected by water ingress. That may result in internal corrosion and a more significant
reduction of the service life of pump and engine.
Troubleshooting
Problem
Cause
Remedy
The pump fails to generate
sufficient water pressure,
the water jet is intermittent
and the water flow is low
1.
Nozzle with a large opening used
2.Blocked water supply
3.Low volume of water supply
4.Clogged screen on water supply line
5.Clogged or leaking high-pressure hose
6.Supply water temperature too high
7.Water pressure leakage from the gun
8.Clogged nozzle
9.Damaged pump
10. Improper priming of pump during the
self-priming mode
1.Replace it with a nozzle of the correct size
2.Check free water flow
3.Use a higher water pressure or a hose of
larger diameter
4.Clean the screen or replace it with a new
one
5.Remove contaminants, turn the hose
around, flush it or replace it with a new hose
6.Procure a supply of colder water
7.Check the connections for tightness, replace
the gun
8.Clean the nozzle with a steel wire and flush
it with flowing water
9.Contact a servicing centre
10. Check all the connections on the inlet side
for tightness, prime the pump as instructed
