EMAK Oleo-Mac PW 300 HC Manuel D'utilisation Et D'entretien page 24

• Use only Diesel for motor driving. The use of any other fuel can be dangerous.
• During the operation, do not cover the water cleaner and do not place it where its ventilation could be
impaired; never cover the stack (28) emitting the boiler exhaust gases.
• When you use the water cleaner in closet environments, make sure that the exhaust gases are evacuated
in the correct way and that there is a correct ventilation (poisoning danger).
• Never bend onto the stack (28), nor touch it with bare hands (burning danger).
WARNING
• If you use the water cleaner at room temperature that is higher than 40 °C/104 °F, do not let it directly
under the sun.
• If the water cleaner is used beyond 1000 m/3280 ft of height, apply to a Skilled Technician for a check
and a possible combustion adjustment.
5.1 Preliminary Procedures
• Unroll the high-pressure pipe (7) completely.
If you have a model equipped with hose reel (4), unlock the device by rotating the ring nut in counter-
clockwise direction (3); unwind the hose quantity that you need, by rotating it in counter-clockwise
direction by using knob (5); lock the device by rotating the ring nut (3) in clockwise direction.
• Fix a supply hose having an inner diameter of 18 mm/0.7 in. to the water suction connector (35), by
tightening with a suitable collar clamp. Operation D of Fig. 2.
• Open the water supply tap, by paying attention that there is no dropping. Operation E of Fig. 2.
• Make sure that the main switch (2) and the temperature adjusting knob (27) are set to off (position "0")
and engage the plug in the power supply socket. Operation F of Fig. 2.
• Set the main switch (2) to position "1".
• Press the cleaner gun's control lever (24) and wait for a continuous jet of water to be issued.
• Turn the main switch (2) to position "0" and connect the lance pipe (16)) to the cleaner gun (17).
5.2 Standard Operation (high pressure) with Cold Water
• Check that the temperature adjusting knob (27) is set to off (position "0") and that the nozzle-holding
head (18) is not set to detergent supply (see also paragraph "Operation with detergent").
• Restart the water cleaner by setting the main switch (2) to "1".
Note: during this restart phase, the high pressure cleaner will immediately stop operating after the initial
peak, as the Total Stop device will take effect.
• Use the cleaner gun's lever (24) to start operation of the high pressure cleaner and thus start cleaning.
• The pressure value can be read on the pressure indicator (30).
5.3 Standard Operation (high pressure) with Hot Water
WARNING
• During the filling/topping-up operations of the gas oil tank, pay attention not to confuse the tanks. If
you pour gas oil into the detergent tank by mistake, do not use the water cleaner and apply to a Skilled
Technician.
• During the filling operations of the gas oil tank, pay attention not to pour liquid onto the water cleaner.
In case this happens, wait at least 24 hours before restarting the water cleaner, so that the fluid that has
possibly entered the device can evaporate.
• Remove the plug (32) and by paying attention not to make the fluid overflow (we recommend to use a
funnel only for this operation), fill the tank (max. capacity of 20 l/5.3 US gal) with gas oil for motor driving;
close the tank.
CAUTION
• The use of agricultural gas oil for heating or dirt causes excessive deposits onto the burner, thus
impairing its good operation.
• Check that the nozzle-holding head (18) is not set to detergent supply (see also paragraph "Operation
with detergent").
