defined in the Troubleshooting section! Any dry cycling of the pump for a period
exceeding 30 seconds may result in damage!
Any material damage caused due to inobservance of this instruction renders the warranty void.
Engine
The engine
MUST
be filled with the correct amount of engine oil supplied with the
delivery before its first commissioning. The bottle with engine oil may contain larger
amount than required for the particular engine type. For specifics refer to the
Technical data section. For easier cold engine start, we recommend reducing the
water outlet pressure according to the instructions on page 8. Set the pump on a
horizontal surface. Open the oil sump plug, also fitted with the oil gauge. Fill the
engine with approximately
¾
of the oil amount required. Screw the plug back into the
oil sump. With the
C
switch se to the
OFF (0)
position (see the figure below), cycle
the engine by pulling the starter cord. Remove the plug, wipe the gauge dry and check
the engine oil level.
CAUTION:
To get the correct reading, the gauge must be fully screwed in place. Top
up the oil to achieve the final level between the MIN and MAX marks.
Remove the plug and fill the tank with petrol carefully. To ensure full performance of the engine, use fresh petrol
with the octane rating of 91 or higher. The physical properties of old and vapid petrol are different and it may
cause an uneven run of the engine or reduced pump performance.
Use clean and oil-free petrol only - your
engine is a four-stroke type.
DANGER
When in operation, the engine
produces
carbon monoxide,
which is a colourless and odourless poisonous gas. Inhalation of carbon monoxide may cause nausea,
headaches, dizziness, vomiting or even death! The device may be used outdoors only, with proper
ventilation ensured. It is also necessary to prevent ingress of exhaust gases into enclosed rooms via
unsealed openings. When working with the engine on, turn the device in such direction, where the
exhaust does not remain pointed at persons standing in the vicinity or any opening in nearby structures
(garages, galleries, cellars, etc.). When in operation, the engine produces waste heat, resulting in heat-
up of various engine components (exhaust, engine cylinder), which may cause serious burns. These
components may cause fire, when in contact with flammable materials.
DANGER
Petrol fumes are extremely flammable and explosive substances that max cause burns, fire or even
explosion, when handled improperly. Let the engine cool down for 5 minutes before adding petrol into
the tank. Then proceed with careful removal of the tank lid and start pouring the petrol in with caution.
NEVER fill the fuel up to the rim, since petrol warms up during engine operation and swells, which may
result in leakage through the lid and subsequent explosion of fire. NEVER tip the high-pressure device
into such position, where petrol may leak from the tank. NEVER attempt to start the engine with damaged
components in the fuel supply, ignition or safety features.
The turn the fuel switch
D
into the
ON (I) position.
Shift the speed control lever
B
into the position.
Shift the choke control lever
A
into the
CHOKE
position.
Grasp the pump grip with one hand firmly and use the other
hand to hold the starter cord grip.
Pull the starter cord to the point, where you feel resistance
from the engine. Then pull the grip sharply to prevent recoil.
If the engine fails to start on the first attempt, depress the
gun and relieve the water pressure in a safe direction. Then
repeat the starting process by pull the starter grip again.
