Starting And Turning Off The Pressure Washer - HERON 8896351 Bersetzung Der Ursprünglichen Bedienungsanleitung

OPERATION AT HIGH ABOVE SEA LEVEL ALTITUDES
y At a higher above sea level altitude (above 1500 m
a.s.l.) the fuel:air ratio changes in the carburettor
towards flooding with fuel (insufficient amount of
air). This results in a loss of performance, increased
fuel consumption, carbonisation of the engine,
exhaust pipe, spark plug and more difficult starting.
Operation at high above sea level altitudes also
negatively affects exhaust fume emissions.
y In the event that you wish to operate the pressure
washer at an altitude greater than 1,500 metres above
sea level for an extended period of time, have the carbu-
rettor readjusted at an authorised service centre for the
HERON® brand.
Do not adjust the carburettor yourself!
•
ATTENTION
y Even with the recommended readjustment of the car-
burettor, the performance nevertheless declines by
about 3.5 % per every 305 m of above sea level alti-
tude. Without performing the above-described read-
justments, the loss in performance is even greater.
y When the pressure washer is operated at an above sea
level altitude that is lower than for which the carburet-
tor is set, the carburettor has a lower fuel mixture, which
again results in a loss in performance. Therefore, it is
necessary to readjust the carburettor.
V. Starting and turning
off the pressure washer
1. With the engine turned off, open the water inlet to the
supply hose and press the trigger of the spray gun.
Through the pressure of the supply water, the pump
will be flooded (primed) and water will flow out of the
spray gun.
2. Setting the fuel valve lever (fig. 1, position 12) to the
"ON" position will open the fuel supply.
3. Set the choke lever (fig. 1, position 11) to the "START"
position.
4. Set the power switch (fig. 2, position 10) to the "ON"
position.
5. Slightly pull out the handle of the pull starter (Step 1,
fig. 9) and then tug it out quickly (step 2, fig. 9).
y If the pressure washer does not start, holding the handle
of the pull starter with your hand allow it to return to its
initial position and repeat the starting process.
•
ATTENTION
y Do not release the handle of the manual starter, rather
allow it to return to the initial position while holding
it since releasing the handle suddenly from the pulled
out position would result in a rapid return and this
could cause damage to the starting mechanism.
6. When the engine starts, gently set the choke lever (fig.
1, position 11) to the "RUN" position.

y In the event that while moving the choke lever, the
engine were to be throttled, immediately return the
choke lever back and wait a few moments and then
attempt to again gradually set it to "RUN".
y To start the pressure washer with a warm engine that
has been running for an extended period of time, it
may not be necessary to set the choke lever to the
"START" position to start the engine. It is, however,
necessary to check this by performing a practical test
in the event that the engine cannot be started with
the choke lever set in the "RUN" position.
7. After starting the engine, open the water inlet into the
supply hose as quickly as possible, hold the spray gun
in your hand, point the spray gun at a safe location,
where there are no people or animals and keep the
nozzle at a safe distance from the area at which the
water from the nozzle will be sprayed. In the event that
the nozzle is very close to a surface, this will result in
a high reactive kickback through the effect of pressuri-
sed water from the nozzle and this could result in loss
of control over the spray gun and a dangerous situati-
on could arise.
Note:
y Initially, the water current from the pressure washer may
be intermittent due to air being pushed out of the sys-
tem by water. In the event that it continues to be inter-
mittent, then air is being pulled in through the cap nut-
-hose adapter-hose array or air is being pulled in at the
coupling of the metal part of the spray gun to the spray
gun, and then it is necessary to seal this with plumbing
Teflon tape or Teflon thread and pull it tighter.

ATTENTION:
EXCESSIVELY HOT WATER SAFETY BLEED VALVE
y In the event that after a certain time, with the engine
running, the trigger of the spray gun is not pulled (i.e.
water is not flowing through the pump), hot water will
start flowing from the safety bleed valve (fig. 2, position
7). In the event that cold water is not flowing through
the pump, which cools the pump down, then after
a certain time the water in the pump will heat up to
above 50°C and to prevent the pump from becoming
damaged, hot water will be bled out and cold water
will be drawn from the supply hose to cool the pump
down. Hot water will not be bled while spraying water
from the spray gun (while water is flowing through the
pump), unless the temperature of the supply water is
higher than 50°C. In the event that the temperature of
the supply water is greater than 50°C, water will be bled
from the safety valve and in such a case stop supplying
the pressure washer with excessively hot water and turn
off the engine of the pressure washer.
