•
Unscrew the plunger retaining cap
from the pump barrel by rotating the
handle.
•
Withdraw the plunger and apply
silicone grease to the O-ring.
•
When re-assembling ensure the O-ring
is not trapped between the outer edge
of the plunger moulding and the inside
of the pump barrel.
Pump non-return valve:
(situated at the bottom of the pump barrel)
•
This stops the compressed air in the
container from escaping back into the
pump.
•
If it is faulty, the unlocked pump handle
will rise when the container is
pressurised.
•
To remove the valve, lift the edge of
the valve and pull. ( take care not to
damage the sealing face of the barrel).
•
To replace, place the valve over the
centre hole and push down firmly.
Pump barrel sealing rings:
•
These make an air tight seal between
both the pump barrel and adapter;
•
Also between the adapter and
container when both are screwed
down tight.
•
To check this, turn the pressurised
sprayer upside down and if there is a
leak, liquid will be forced from the
joints.
Nozzle cap:
•
Keep this clean and free from
obstruction.
•
Also, the two swirl grooves at the end
of the lance must be kept clean and
free from sediment to ensure a good
spray pattern.
•
The nozzle O-ring should be kept
lubricated with silicone grease.
Lance:
•
Keep the trigger clean and free from
build up of sediment and chemicals by
regularly flushing through after use.
•
Of necessary remove and clean the
shuttle in the trigger.
Outlet and dip tube:
•
To rewash the outlet or replace the dip
tube, unscrew the hose nut and pull
the outlet spigot and dip tube through
the outlet body.
Winter use:
•
Drain liquid from all parts after use to
prevent damage from freezing.
Annual maintenance:
•
At least once a year thoroughly clean
the whole sprayer and apply silicone
grease to all moving parts.
•
Test with water and if any washer or
seal has perished it must be replaced.
