PRODUCT DESCRIPTION
Upon opening the box of your new PGPS-016/020 please check all the parts conform to the parts index. Then assemble the machine as required.
The sprayer is supplied with a selection of 3 nozzles which are suitable for the majority of spraying tasks.
1CONICAL NOZZLE 2DUAL CONICAL NOZZLE 34 HOLE ADJUSTABLE NOZZLE
Cone nozzles produce a solid cone shaped
spray pattern with a round impact area;
these nozzles ensure a precise uniformed
distribution of liquids throughout the entire
circular impact area.
The Dual Cone nozzles produce two solid
cone shaped spray patterns with a round
impact area; this nozzle covers a larger
area than the standard Cone Nozzle.
The four hole adjustable nozzle gives a finer
spray as opposed to a jet, fan or conical
spray nozzle but over a larger area than a
standard single hole nozzle.

contaminate the environment or water mains network.
Avoid any overflow from the tank and any contamination of
public waterways, drainage and water channels.

pump lever.
By squeezing the shut-o trigger valve,
liquid will be forced through the spray nozzle.
When the shut-o trigger valve is released, the spray will stop.

CLEANING THE FILTER IN THE SPRAYER HANDLE
• Unscrew the union nut and pull the hose with filter out of the
sprayer handle.
• Rinse the filter under running water and reattach the sprayer
handle.
CLEANING THE PUMP
• lf the pump does not provide pressure after cleaning your
backpack sprayer you must also clean the pump.
• Push out the locking ring (using a screwdriver, for example) and
pull the joint rod out of the pump.
• Unscrew the union ring and pull out the pump.
• Inspect the pump O-ring and install a new O-ring if necessary.
• Pull out the inner part of the pump and the gasket.
• Clean all pump parts and gaskets with water (and detergent).
Reassemble the pump in the reserve order.
STORAGE
• Even though the tank is manufactured from UV stabilized
material we recommend that the unit is protected from direct
sunlight and stored in a dry room, away from children and
animals.
• Do not keep in areas subject to frost, always drain all the liquid
from tank, pressure tank and hoses.
• Please always use ParkerBrand replacement parts available from
parkerbrand.com.
GENERAL MAINTENANCE
• Regularly check the spray tank.
• Regularly check spray line and connectors.
• Clean all filters and check for any damage, To protect piston,
cylinder and piston collar 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.
• After disassembly of pump components or after replacing the
piston collar, use water resistant grease to lubricate the piston
and the collar.
• At least once a year clean pump thoroughly, re-grease or
lubricate all moving parts.
After every spraying operation, the Sprayer should be cleaned
to avoid corrosion of internal parts and blockages of the nozzles
caused by chemicals. In addition, proper cleaning can also avoid
the risk of contaminating other chemical agents being sprayed in
future operations that may bring harm to plants and crops.
CLEANING THE BACKPACK SPRAYER
• Press the trigger on the sprayer handle to release the pressure
remaining through the lance.
• Unscrew tank cap, if the outside of the cap is dirty, thoroughly
clean the area around the thread and thread O-ring
• Clean the inlet filter and tank cap in clean water.
• Empty the tank and fill with clean water (with detergent added to
the water if necessary).
• Spray the water out of the backpack sprayer until the tank is
empty (This cleans the nozzle and valves).
• Leave the backpack sprayer open and allow it to dry.
• Clean the outer surface of the Sprayer with a wet cloth.
• The tank strainer can be removed for cleaning.
