1) Turn on the water supply tap fully. 2) Release the safety catch (D). 3) Depress the gun trigger for a few seconds and start up the appli ance using the starter device (ON/1). AS models -In AS models with automatic delivery ow cut-o system: -When the gun trigger is released the dynamic pressure automati cally cuts out the motor (see g.4); -When the gun trigger is depressed the automatic drop in pressure starts the motor and the pressure is restored after a very slight delay; -If the AS is to function correctly all gun releasing and depressing operations must be performed at intervals of less than 4-5 seconds. To prevent damage to the appliance, when running do not stop the water jet for more than 10 minutes at a time. 7.3 Stopping the appliance 1) Set the starter device switch on (OFF/0). 2) Depress the gun trigger and discharge the residual pressure inside the hoses. 3) Engage the gun safety catch (D). English 19 7.4 Restarting 1) Release the safety catch (D). 2) Depress the gun trigger and discharge the residual air inside the hoses. 3) Set the starter device on (ON/1). 7.5 Storage 1) Switch the appliance o (OFF/0). 2) Remove the plug from the socket. 3) Turn o the water supply tap. 4) Discharge the residual pressure from the gun until all the water has come out of the nozzle. 5) Drain the detergent tank. 6) Engage the gun safety catch (D). 7.6 Relling and using detergent When using detergent, the adjustable nozzle must be set on " " (on models with this feature). Fill the tank with highly degradable detergent. 7.7 Recommended cleaning procedure Dissolve dirt by applying the detergent mixed with water to the surface while still dry. When dealing with vertical surfaces work from the bottom upwards. Leave the detergent to act for 1-2 minutes but do not allow the surface to dry. Starting from the bottom, use the high pressure jet at a minimum distance of 30 cm. Do not allow the rinse water to run onto unwashed surfaces. 8 MAINTENANCE FIG.5 Any maintenance operations not covered by this chapter should be carried out by an Authorized Sales and Service Centre. Caution -Danger! Always disconnect the plug from the power socket before carrying out any work on the appliance. 8.1 Cleaning the nozzle 1) Disconnect the lance from the nozzle. 2) Remove any dirt deposits from the nozzle hole using the tool (C1). 8.2 Cleaning the lter Clean the suction lter (L) and the detergent lter after every 50 hours of operation. 8.3 Unjamming the motor (on models with this feature) In case of lengthy stoppages, limescale sediments may cause the motor to seize. To unjam the motor, turn the drive shaft with a tool (M). 8.4 End-of-season storage Treat the appliance with non-corrosive, non-toxic antifreeze before storing it away for winter. 20English 9 TROUBLESHOOTING Problem Possible causes Remedy Pump does not reach working pressure Nozzle worn Replace nozzle Water lter fouled Clean lter (g.5) Water supply pressure low Turn on water supply tap fully Air being sucked into system Check tightness of hose ttings Air in pump Switch o the appliance and keep depressing and releas- ing the gun trigger until the water comes out in a steady ow.
