PUT INTO OPERATION
put the high pressure cleaner as much as possible in a horizontal position.
Check the water supply - oil level engine & pump - sufficient fuel in the tank. put
the fuel valve open (if available). Connect the spray gun with the high pressure
hose (without spray lance) to the high pressure cleaner. open the fuel tap (if
present). Turn the main switch to position on or turn on the key contact to
position STaRT. Starts the engine with key (electrically) or with the start rope
(manually) until the engine starts. First choke @ cold start (@version with petrol
engine)! put the choke in the open position while the engine is warming up.
after a longer period of non-use or at the first start of the engine, run at low
speed and without load during 20 seconds! The motor goes automatically
to idle speed (via ETC) at not operating the spray gun. aim the spray gun to
the free space and operate the spray gun until the water jet is completely de
aerated (+- 30 sec.). Turn the operating switch/key contact to position oFF.
Connect the spray lance to the spray gun. Start the engine again and give time
to reach operating temperature. next, close the choke lever again(@version
with petrol engine). When the spray gun will be released, the cleaner will go
in automatic speed control. The engine will turn at idle speed by means of the
pressure control.
Never turn the motor without an air filter, since
these lead to a quick wear of the motor.
TURN OFF THE CLEANER
Do not choke the carburetor, to stop the engine. Turn the key contact to the oFF
position or move the operating switch to the oFF position. aim the spray gun in
to the free space and operate the spray gun until the water jet is completely de
aerated (+- 30 sec.). Close the fuel tap (as wished).
PUMPS HT
There must be present a pre- pressure (pump) at hT pumps (pumps with high
temperature). The pre- pressure (pump) must provide for sufficient flow of
water to feed the pump and to occur cavitation. Cavitation is the phenomenon
that in a moving fluid the local pressure is going to be lower than the vapour
pressure of the fluid. Because of this mist bells will arise who can implode with
high power in the pump and could cause damages. For all these applications at
high temperature, it is aBSoluTEly ESSEnTIal to feed the pump with positive
pressure (at least 3 bar) and with a sufficient quantity of water.
