Cleaning and Maintenance

Pressure release valve
 The safety valve is designed to release any excess pressure and to let you release the pressure after
spraying.
 Do not interfere with the setting of the air pressure safety valve.
Plunger head
 The O-Ring should be kept lubricated to slide freely in the barrel and so pump air efficiently.
 To apply grease proceeds as follows.
 Remove the pumps assembly by unscrewing in an anti-clockwise direction.
 Locate the pump handle into the carrying position and grip the barrel.
 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 pressurized.
 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 pressurized 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 sediment and chemicals by regularly flushing through after use.
 If 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
