8. Operating and maintenance instructions
8.1 General operating and maintenance
instructions
After running in the device for approximately 5
operating hours, check all accessible nuts, screws
and bolts to ensure that they have not become
loose. Retighten them as required.
Every time you use the backpack sprayer, first
check it all over to ensure it is safe to use.
8.2 Checking the delivery rate of solution
At least once at the start of every spraying season,
check whether the delivery rate of the sprayer
(measured in litres per minute) still corresponds to
the value indicated in section 7.2 "Spray nozzle /
delivery rates".
For this, fill up the tank to the maximum marking,
start it up and spray for exactly one minute.
Then measure the quantity of water required to
refill the tank to its maximum level.
The value measured corresponds to the amount of
water delivered by the device in l/min for the
selected operating pressure. This value must not
deviate by more than 10 % from the value
indicated in section "7.2 Spray nozzle / delivery
rates".
If the actual value is too low, this may be caused
by deposits in the nozzle. Clean the nozzle 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.
8.3 Information on using the rechargeable
battery
When used properly, the rechargeable battery will
remain in good working order for many years. It is
important to note that the rechargeable battery
should never be fully discharged.
If the operating pressure built by the pump while
spraying drops noticeably and the pump fails to get
the pressure back up to the normal operating level,
stop spraying with the current battery and recharge
the battery.
If the backpack sprayer with rechargeable battery
is not used for an extended period of time then we
recommend recharging the battery once a month
with the supplied charger. This will prevent the
battery from deep-discharging.
Alternating between two batteries
We recommend purchasing a second rechargeable
battery if you need to be able to keep working
indefinitely without having to stop when the battery
is dead. Also remember to order the SOLO
charging cable, part no.: 5900789. This second
charging cable will allow you to recharge the
second battery independently of the backpack
sprayer.
When alternating between two batteries you can
use one of the rechargeable batteries to run the
sprayer while the second rechargeable battery is
recharged by the charger via the separate charging
cable. The batteries are easy to swap – simply
open the protective casing and undo the Velcro
strap. Ensure that the polarity is correct when the
cables are connected to the rechargeable battery
(see section 5.1) and that the battery is firmly
secured with the Velcro strap.
8.4 Replacing the fuse
Replacement glass fuses (5x20 mm 4A) are
available to order from your local SOLO dealer
under the part no. 0084055.
To replace the fuse, release the fuse holder (14)
with a screwdriver (turn it half a turn anti-clockwise)
and then pull it out.
After inserting a new fuse, slide the fuse holder
back in and lock it by twisting it half a turn
clockwise.
If the fuse blows repeatedly have the device
checked by a specialist workshop before returning
it into use.
