Regular Checks; Maintenance And Care - Solo 425 Originalbetriebsanleitung

 When removing the spray tube from the machine
always point the end of the tube away from
yourself.
For the operator and possibly the chemical
manufacturer to test the material resistance to
certain chemicals, the product manufacturer will
provide details of the type of materials used for the
Pressure Sprayer. Any unauthorized modification or
changes made to the Pressure Sprayer will
automatically exclude liability claims against the
manufacturer.
4. Check list for completeness

 1 pc. each symbolic label for
container content: herbicide,
fungicide and insecticide.
NOTE:
Affix the appropriate label to identify
the container content.
PLEASE NOTE:
Never pour different agents at the same time into the
container. Before using a different agent, thoroughly
clean out the container and all parts in contact with
the spray agent, then flush with plenty of water. We
recommend the SOLO horticultural equipment
cleaner in 500 ml bottles; part no. 49 00 600

5. Regular checks

At the start of the season and in regular use, check
the following at least once a month by means of a
test run using water:
 Tightness of all equipment components at
maximum permissible pressure and closed manual
valve
 Function of all active components
 Dosing and distribution accuracy whilst in use
 Checking the delivery rate of solution
For this, fill the equipment up to the maximum marker
with water, start using the equipment and spray for
one minute exactly with 2 bar operating pressure.
Then measure the quantity of water required to refill
the tank to its maximum level.
The actual volume measured represents the flow rate
of the equipment in l/min at 2 bar operating pressure.
This value must not deviate by more than 10% from
the value indicated in chapter 16 " Specification of
nozzle tips ".
If the actual value is inadequate, this may be caused
by a contaminated nozzle or filter. Clean these parts
and repeat the test.
If the actual value is too high, this may be due to
wear or damage to the spray nozzle.
When checking the solution delivery rate of the
device, also check whether the nozzle is producing
an even, fan-shaped spray pattern.
If the flow rate is still inadequate even after cleaning,
replace the relevant components with original spare
parts.
Generally use only original spare parts with the
correct grade when replacing wearing parts.
Filter grade in front of the filter nozzle: 0.8 mm
Sieve funnel filter: 2.0 mm

6. Maintenance and care

The SOLO Backpack Sprayer is almost maintenance
free. If the tank lid becomes hard to tighten or open,
apply all to the lid gasket.
Proper Maintenance also includes:
 Regular check of the spray tank,
 Regular check of spray line and screw connectors,
 Clean all filters and check for any damage,
To protect piston, cylinder and piston collar (models
425/435/ 473P) from impurities in the spray solution,
an additional filter is fitted on the inlet side of the
pressure tank. This filter can be cleaned by
vigorously shaking the tank when flushing it.
With models 425/435/473P: After disassembly of
pump components or after replacing the piston collar,
use water resistant grease to lubricate the piston and
the collar.
In case of unexpected problems please refer to your
SOLO Dealer.
