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. B) is in the
OFF (0) 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 (page 4)
The pump fails to draw the
cleaning agent
1.Wrong nozzle used
2.The priming hose is not dipped in the
cleaning agent or it is clogged
3.Clogged hose or strainer
1.Replace the high-pressure nozzle with a
low-pressure (black) one
2.Check the volume of cleaning agent and
adjust the position of hose
3.Clean the washer with flowing water,
replace the priming hose
