Service jobs and parts

Winter storage and frost protection

Storage · every year

Portek's storage steps: flush with clean water, blow the lines out with compressed air, run anti-freeze through until it comes out coloured, then store inside.

Part	Qty	Notes	Part number
Anti-freeze	1	A small amount	check your handbook

Step-by-step

Wear gloves and eye protection. Fill the tank with clean water, run the pump and spray through the lance and boom until clean water comes out.
Blow out the hoses with compressed air to remove the water.
Pour a small amount of anti-freeze in the tank and run the pump until coloured liquid comes out of every spray end.
Close the spray ends so the anti-freeze stays in. Disconnect the battery clips.
Store inside, clean and dry in a ventilated place. If a boom hangs lower than the tank, stand the sprayer on pallets.

Tools: Compressor with air line, Pallets, Chemical-resistant gloves

Sprayer test (NSTS) if a boom is fitted

Legal · every 6 years

Hand-held lances are outside the NSTS cycle but must be checked regularly. If you fit a boom of 3 m or less, NSTS puts it on a 6-year test cycle, with the first test before it is 5 years old (Welsh Government guidance on NSTS categories).

Step-by-step

If you use the lance only, skip this test but check the hose, lance and regulator for leaks before each season.
With a boom fitted, book an NSTS test before it is 5 years old and then every 6 years.
Clean the sprayer fully before the test. Wear gloves and wash your hands afterwards.

Tools: Nozzle brush, PPE as the last chemical label says

Decontaminate after use

Spray system · when needed

Portek says the tank, pump, hoses and lance must be decontaminated after every use, to stop residues damaging crops and corroding or blocking the sprayer. There is no hour interval.

Part	Qty	Notes	Part number
Tank cleaning agent	1	As the chemical label recommends	check your handbook

Step-by-step

Wear the PPE the chemical label asks for. Portek says PPE must still be worn while cleaning.
Clean in the field just treated or somewhere that cannot contaminate water, streams or crops.
Drain the tank and rinse it; pressure-wash the inside.
Fill with clean water and spray it through the boom and lance.
Add cleaning solution, run the pump 5–10 minutes to mix, then leave it in the tank about 8 hours.
Soak nozzles, screens and filters in cleaning solution and brush them. Never blow through a nozzle by mouth or clear it with wire.
Refit and rinse the whole system with clean water. Wash gloves before taking them off and wash your hands.

Tools: Pressure washer, Bucket, Nozzle brush, Chemical-resistant gloves, Face or eye protection

Clean the suction strainer and nozzles

Spray system · when needed

Portek says clean the suction strainer on the pump suction line periodically, and clean nozzle filters, tips, caps and gaskets by soaking and brushing. Replace any nozzle whose output is more than 10% off.

Part	Qty	Notes	Part number
Suction filter (10 mm hose)	1	Genuine Portek	088/014
Suction filter (13 mm hose)	1	Genuine Portek; for 13 mm hose models	088/011
Basket filter (tank neck)	1	Genuine Portek	088/045

Step-by-step

Disconnect the battery clips. Wear chemical-resistant gloves and eye protection.
Unscrew the suction strainer lid, take out the filter and flush it under clean running water.
Soak the nozzle tips, caps and gaskets, brush them and let them dry.
Refit, reconnect and check each nozzle's output with a jug: replace or clean any that is more than 10% out.
Wash gloves before taking them off and wash your hands.

Tools: Nozzle brush, Bucket, Measuring jug, Stopwatch, Chemical-resistant gloves

Check mounting straps

Mounting · when needed

Portek says check the tank is still secure after the first 15 minutes of work and re-tighten the ratchet straps. A loose 107 kg tank can tip a quad.

Part	Qty	Notes	Part number
Ratchet straps	2	Replace if frayed; Portek number not listed	check your handbook

Step-by-step

Stop the quad and take the key out.
Check both ratchet straps are tight and not frayed, and the tank has not shifted.
Check the full weight is within the quad's rack limit in its handbook. Do not drive across slopes.

Known problems

Pump cycling

If the pump keeps switching on and off, nozzle delivery is too low for the pressure. Turn the regulator down or change the nozzle: cycling shortens battery and motor life.

Run with the regulator open

Portek says open the regulator fully before running the pump to avoid premature pump wear.

Repair guides

Frost damage: split pump, valves or gauge, and frost-proofing (Moderate, 1–2 hours (plus parts)): After a frost: pump leaking from a cover, cracked valve housing or filter bowl, gauge needle stuck or glycerine leaking, no pressure on the first fill of spring.
12 V pump cycling, won't run or low pressure (quad sprayer) (Easy, 30–60 minutes): Pump keeps switching on and off with the lance shut, pump doesn't start, pump runs but pressure is low or the lance spits, flat quad battery.
Quad sprayer calibration (owner check, boom fitted) (Easy, 1 hour): Not sure of the rate being applied, new nozzles fitted, different speed or chemical, uneven boom output.

The full step-by-step guides are in Farmyard Workshop once you add your implement.
