7.3.
Ensure that both nozzles are kept clean and free of debris.
7.4.
Check unit, gun, nozzle, hose, connections and cables for damage. Immediately replace or repair with genuine parts.
7.2
Storage.
Do not store the unit in premises subject to freezing conditions. If this cannot be guaranteed then the unit should have a
glycol based antifreeze run through it. Immerse the water supply pipe into a container of antifreeze. Immerse the gun/lance into the
same container (without the nozzle attached). Hold the gun trigger open and start the unit. The antifreeze will be drawn into the unit by
suction. When an even, bubble free flow is obtained switch the unit off.
7.3.
Starting the unit after a long period of storage.
Scale deposits may form in the pump when it has not been used for some time.
This may cause the motor to run stiffly or it may not start up at all. In these circumstances it will be necessary to turn the motor by
hand. To do this it will be necessary to open the casing as indicated above.
This is the only user service operation recommended
where the casing is opened. Any other servicing required to internal parts should be carried out by a recommended service
dealer.
7.3.1. Unplug the unit from the power supply.
7.3.2. Unscrew the four screws holding the rear cover panel in place using a T20 TRX screwdriver or bit. (See fig.13). If the hose reel kit is
installed, unscrew the same screws which are used to hold the reel supports in place.
7.3.3. By means of a suitable screwdriver having a pozidrive No2 tip unscrew the four screws holding the handle and front cover in place.
The upper fixing screw positions will be revealed when the rear cover has been removed. (See fig.14).
7.3.4. Remove the handle and front cover assembly by moving it forwards first and then upwards as indicated by arrow ‘A’ in fig.15. Ensure
that the cover is detached from the ON/OFF switch before lifting the cover off. (See ‘B’ in fig.15). At the bottom of the front cover there
are two long plastic legs which hook inside the frame of the detergent tank. It may be necessary to reach under the lower front edge of
the tank to release the legs from their notches in the frame. (See fig.15-C).
7.3.5. Insert a 4mm hexagon key through the middle opening in the fan cover and into the hexagon socket in the end of the motor shaft.
Turn the motor shaft clockwise by hand several times. (See fig.16).
7.3.6.
Remove the hexagon key.
7.3.7. Refit front cover and rear cover.
7.3.8. Connect the water supply, high pressure hose and gun and plug into the mains power supply.
7.3.9. Test the unit by starting the machine with the spray gun trigger held open.
