INSTALLATION - ASSEMBLING THE ACCESSORIES
AND FILLING THE ENGINE CRANKCASE WITH OIL
• Fix the handle (4) to the frame (3) using the kit supplied: screws (5), washers (6) and knobs (10) for
FDX-PRO; screws (5), washers (6) and nuts (7) for all the other models (in this case use a 13 mm fixed
jaw spanner, not supplied). Operation A in Fig. 1, 2, 3 and 4.
• Unwind the high pressure hose (30) and screw the end without the quickfit coupling onto the spray
gun (19) thread and tighten well with two 22 mm fixed jaw spanners (not supplied). Operation B in Fig. 8.
NOTE: the FDX Xtreme high pressure hose (59) has two quickfit couplings (34) so you need no spanners
to screw it onto the spray gun – simply screw right down and tighten the ring nut by hand: connect
the quickfit coupling (34) to the sleeve-free end (60) of the spray gun.
• Connect the quickfit coupling (34) to the water outlet fitting (15), screw down and tighten the ring nut
by hand. Operation C in Fig. 8.
• Insert the gasket (49) (FDX-PRO, FDX4 and FDX Xtreme) or the water inlet filter (39) (for all the other
models) in the water inlet fitting (16) and screw the water inlet hose-end fitting (11) on to it. Operation D
in Fig. 8.
• Clamp (37) the free end of the detergent suction hose (31) to the detergent suction fitting (36).
Operation E in Fig. 8 (not for FDX2 10/150 and FDX Xtreme).
• Fill the engine crankcase with oil, following the instructions given in the relevant operating and
maintenance manual (this is not to be done on machines with Diesel engines as they are filled with
oil in the factory).
• Do the preliminary activities described in the operating and maintenance manual of the engine
mounted on the high pressure cleaner. In particular remember to fill with fuel and check the level of
engine oil.
NOTE: the FDX Xtreme model has a capacious tank (28) integrated in the high pressure cleaner frame.
• When the engine is off and the machine is completely cold, check the level of pump oil by way of the
level indicator (38). This does not have to be done on the FDX2 10/150 model which does not have a
pump oil indicator. Also check the gearbox oil level by way of the level indicator (44) on those models
thus equipped.
When topping up is needed please refer to the lubricant types given in the
" paragraph.
data
• Check correct tyre inflation.
• Check that the inlet water filter (39) and the detergent suction filter (40) are clean. The FDX-PRO and
FDX4 models have a professional suction filter (45) that needs to be inspected less frequently which
is also the case for the FDX Xtreme models with filter (23) (please refer to the
paragraph).
• Take the high pressure cleaner to the place of work using the handle (4).
• Engage the parking brake (41) (not for FDX2).
• Unwind the high pressure hose completely (30) or (59).
• Connect a gardening type quickfit coupling (FDX2 10/150 only) to the water inlet hose-end fitting (11)
or, exploiting the clamp (12) supplied, fix a supply hose with an inside diameter of 30 mm/1.2 in
(FDX Xtreme) or 19 mm/0.75 in (for all the other models) to the water inlet hose-end fitting (11).
Operation G in Fig. 8.
• Start the engine, referring to the relevant operating and maintenance manual.
• 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.
• Press the spray gun lever (33) and wait for a continuous jet of water to come through which means
the pump is priming correctly.
• Stop the engine, referring to the relevant operating and maintenance manual, and close the water
supply tap, if any.
• Press the spray gun lever (33) to discharge all residual pressure.
