8. Try rotating the central distribution lever in the central position and then again on the previous channel
to check the correct adjustment of the "CUT-OFF" valve.
NOTE: a correct calibration implies that the pressure rises rapidly from 0 to the previously set pressure
and once this limit is reached, it drops again to 50-100 bar.
9. Once the desired pressure has been set, retighten the "CUT-OFF" valve locknut.
CLEANING OF THE POWER PACK
A regular cleaning is very important for the good functioning of the equipment. A clean product will
immediately allow to find oil leaks or causes of malfunctioning. A clean tool is also more comfortable to
use and guarantees a firm grip.
CLEANING WITH HYDRO CLEANER
• The cleaning with hydro cleaner assures the best results in this type of washing. Put the power pack
on a clean surface or a wooden pallet. Be careful not to use too much the water nozzle near the tool
to avoid the removal of safety stickers and paint, in particular if hot water is used.
• A hot washing with very high pressure and with the nozzle very close to the surfaces, can cause
the removal of the paint and safety adhesives and labels
• Do not insist on the engine electric part with the nozzle – if it is necessary read on the proper
paragraph about cleaning contained in the motor manufacturer’s manual.
• After the pressure washing let the water drip from the machine also by moving it for helping the water
drain from cavities or recessed points.
• With an air gun blow all over the power pack eliminating every trace of water and moisture. Insist on
• With the machine perfectly dry, spray a protective-dewatering product (CRC-or WD40) on all
chromed parts and in the tool cavities. Spray also the area of the ON-OFF valve. For allowing the
spray to reach all points, move the movable parts.
• Dry up completely the tool handles for guaranteeing a firm grip
• Start the power pack and make it work at minimum for a few minutes
CLEANING WITH RAGS OR PAPER
• The pack can also be cleaned with a damp rag, using a brush with gasohol or an air gun for
eliminating all traces of dirt and oil
• Clean in particular the recessed points and cavities and the connection surface of the quick couplers.
• With the machine perfectly dry, spray a protective-dewatering product (CRC-or WD40) on all electric
parts, near the ON-OFF valve and in the cavities. For allowing the spray to reach all points, move the
movable parts.
• Clean and dry up completely the tool handles for guaranteeing a firm grip.
