• Using the clamp (63) supplied, fix a supply hose with an inside diameter of 19 mm/0.75 in to the water
inlet hose-end fitting (25). Operation H in Fig. 7.
• Completely unwind the high pressure hose (35).
• Open the water supply tap (if connected to the drinking water mains it is mandatory to use a back-
flow preventer: to use this device refer to the relevant instruction manual), making sure there are no
drips. Alternatively, put a suction hose in a tank (not for the S and 1001-1251-1501 models without
Total Stop, as they are fitted with a thermostatic valve and must work only with mains water).
• Make sure the master switch (1) is on "0" position and insert the plug. Operation L in Fig. 7.
• Move the master switch (1) to "1" position (S, TS, Eco, 1001-1251-1501 without Total Stop); move the
master switch (1) to "1" position and press the button (21), KEEPING IT PRESSED UNTIL WATER
STARTS COMING THROUGH THE SPRAY GUN (1001-1251-1501 with Total Stop).
NOTE: the Total Stop device of the 1001-1251-1501 models can control the micro-leaks (using a flow
switch and pressure accumulator); for this reason each time the delivery circuit is not under pressure
(i.e. when the machine is started the first time) or it has no water (i.e. when the high pressure cleaner
hasn't pumped up from the tank), the machine can only be started by putting the master switch (1)
on "1" position and pressing push button (21), keeping it pressed until water starts coming through
the spray gun.
• Press the spray gun lever (22) and wait for a continuous jet of water to come through which means
the pump is priming correctly.
• Move the master switch (1) to "0" position and close the water supply tap.
• Press the spray gun lever (22) to discharge any residual pressure.
• Connect the lance hose (58) to the spray gun (55), inserting it in the quickfit coupling until it clicks into
place (Eco). Operation A in Fig. 7. Connect the lance hose (29) or (33) or (57) to the spray gun (24)
or (54), tightening right down (all the other models). Operation G in Fig. 7.
NOTE: to disconnect the lance hose (58) from the spray gun (55) press the ring nut (59) in the direction
of the spray gun until the quickfit coupling clicks and then take the lance hose off.
OPERATION – PRELIMINARY ACTIVITIES (XTREME)
• Follow the instructions given in the "Routine maintenance" and "Special Maintenance" paragraphs.
• Take the high pressure cleaner to the place of work using the handle (2).
• Engage the parking brake (20).
• Put the plug (46) in the socket (45) and tighten the ring nut (44) right down by hand. Operation M
in Fig. 4.
• Put the regulation valve in minimum pressure conditions, turning knob (8) anticlockwise until it goes
no farther (this is only necessary for models with a 15 kW/20.4 HP motor; in fact, all the other models
are fitted with a pressure resetting regulation valve).
• Using the clamp (63) supplied, fix a supply hose with an inside diameter of 30 mm/1.2 in to the water
inlet hose-end fitting (25). Operation H in Fig. 7.
• Make sure the master switch (1) is on "0" position and insert the plug. Operation L in Fig. 7.
• Move the master switch (1) to "1" position: mains voltage is indicated when LED (43) turns on. If the
emergency push button (40) has been pressed, reset it by pulling it upwards.
• Open the water supply tap (if connected to the drinking water mains it is mandatory to use a back-flow
preventer: to use this device refer to the relevant instruction manual), making sure there are no drips.
• Press the START push button (21) to start the machine.
• Wait for a continuous jet of water to come through from the water outlet fitting (16) which means the
pump is priming correctly.
• Press the STOP push button (42) to stop the machine and close the water supply tap.
• Completely unwind the high pressure hose (61).
• Connect the quickfit coupling (36) of the end with sleeve (62) of the high pressure hose (61) to the
water outlet fitting (16) and tighten the ring nut right down by hand. Operation F in Fig. 7.
• Connect the other quickfit coupling (36) of the high pressure hose (61) to the spray gun (56) fitting
and tighten the ring nut right down by hand.
• Press the spray gun lever (22) to discharge any residual pressure.
