7HAND LANCES

When using hand lances bear in mind the following notes:

=Don’t direct the jet of liquid towards electric power lines or zones where there is electrical current, houses or where people might pass.

=Don’t point the jet at people or animals.

The jet can cause serious injuries simply due to the mechanical force of the liquid under pressure.

=Never block the spraying lever of the lance in an open position because if the lance falls it will be uncontrollable.

=At the end of work after you have stopped the pump, make sure that any residual pressure in the pipes under pressure has been drained to avoid unexpected jets when putting the lance away. There are various types of lances; with a lever, mitra spray gun and pistol grip.

For further information please refer to the handbook in the package.

The lever lance is controlled by opening lever A which, depending on how much it’s pressed, produces a conical spray or direct jet. The standard nozzle is Ø 1.5

The mitra spray gun can produce a direct jet or a conical spray and the type of spray is selected by pushing lever B forwards or backwards. Use lever C to open the jet. The standard nozzle is Ø 2.5

Replacement nozzles are available for all of the lances and the capacities are indicated in the tables TAB.4 and TAB.5 ( page 32).

8MAINTENANCE

All of the maintenance operations and repairs must be carried out with the machine and cardan shaft stopped and the tank and circuit clean of any residues of chemical products.

The maintenance of the mistblower is essential for maintaining a high level of safety. Also consult the single handbooks of the main components of the mistblower.

WARNING: the indications to follow for using chemical products are indicated in paragraph 2.2.1.

8.1PROGRAMMED MAINTENANCE

(TAB. N° 7, page 33)

We recommend using a table of programmed maintenance to follow in time to keep the mistblower in an efficient working condition.

For major and important maintenance jobs we recommend using the normal UNIGREEN assistance service available from your reseller, (if necessary) replacing parts using original spare parts only.

8.2ROUTINE MAINTENANCE

=After every treatment wash the inside of the tank and the entire circuit as indicated in paragraph 4.13

=Periodically check that the suction and delivery filters are clean

=Check the oil level in the volumetric compensator of the pump

=The use of chemical products that are particularly damaging for a nitrile rubber mix can cause the diaphragm to break before time.

In these conditions check the state of the components more often. There are diaphragms made of special materials (viton and desmopan) that are available on request.

=When doing treatments with copper hydroxide you should take great care to thoroughly clean the system, washing it after each treatment because hydroxides attack parts that aren’t painted or protected by hot galvanising.

To prevent chemical attacks we recommend spraying transparent paint on the parts that are most exposed to the product and equipping the mistblower with stainless steel pressure gauges.

8.2.1 CLEANING THE NOZZLES

Check the state of wear of the nozzles and replace them when the delivery is over 30-35% of the theoretical level.

If you notice even a partial blockage of a nozzle proceed as follows:

-drain the pressure and stop the machine

-dismantle the screw or bayonet ringnuts holding the nozzles

-clean with a small brush or compressed air, don’t use nails, punches or bradawls

-reassemble the nozzles and the ringnuts, replacing the filters and seals.

8.2.2 LUBRICATION

The moving mechanical components must be lubricated to prevent wear and
