Question 3

How to clean and unclog the hose of the EPW2-ST5.5 pressure washer?

Accepted Answer

The 8-meter hose of the STERWINS EPW2-ST5.5 pressure washer can become dirty or clogged over time, which reduces water flow or completely stops the jet. Here’s how to effectively unclog and clean it.

Before you begin: Turn off the machine, unplug it, and close the water supply tap. Wait a few minutes for the pressure to drop before handling the hose.

Checking and unclogging the hose: Start by checking that the hose is not bent, crushed, or knotted, as this would reduce water flow. Then detach the hose from the machine and the gun by unscrewing the fittings. To unclog a hose blocked by deposits or limescale, hold the hose vertically and slowly pour warm water (below 40°C) from top to bottom to rinse it. If the water does not flow, the deposit is likely limescale buildup. In this case, fill a bathtub or container with a solution of 1 part white vinegar to 3 parts water, then submerge the hose for a few hours. This solution will gradually dissolve the limescale deposits. Rinse thoroughly with clear water until the water is clear and the vinegar is no longer detectable.

Cleaning the 5-in-1 nozzle: The issue sometimes comes from the nozzle, not the hose itself. The nozzle openings may be partially or completely clogged. To clean the openings, gently insert a fine needle or a paperclip into each opening to remove deposits. Set the nozzle to high-pressure 0° (the precision one) for easier access to the openings. Test each position of the nozzle under a water jet to ensure it does not leak anywhere.

Cleaning the water filter: Before reassembling, inspect and clean the water intake filter, located on the water inlet fitting. A clogged filter significantly reduces flow and can damage the pump. Rinse it under running water to remove particles and debris. Also check the water supply connection adapter and clean it if necessary.

Reassembly and testing: Reinstall the hose by screwing it firmly back onto the machine and the gun. Open the water supply tap, plug in the machine, then pull the trigger until you get a stable and continuous water jet. Let the device run for a few seconds to expel air from the hose and any cleaning residue. Test on a discreet surface before cleaning your usual surfaces. If the flow remains low after these steps, consult the troubleshooting guide or contact customer service.

Question 4

The foam/detergent system does not draw detergent from the tank - what should I do?

Accepted Answer

The detergent suction system of the STERWINS EPW2-ST5.5 cleaner works by depression created by the water flow. When you activate the foam mode (nozzle position 5), water flows through the nozzle and creates a low-pressure area that draws detergent from the connected bottle. If the detergent is not being drawn up, here are the points to check in this order:

Nozzle position: Make sure that the 5-in-1 nozzle is in the foam position (the 5th position). To change position, turn the nozzle to the corresponding pictogram. Only this position activates the detergent suction circuit.
Filled and connected bottle: Check that the detergent bottle contains enough detergent. Also, ensure that the bottle's hose is properly inserted into the cleaner's top cap. A loose or incomplete connection prevents suction.
Detergent thickness: Use a detergent recommended for pressure washers. If the detergent is too thick or concentrated, dilute it with water according to the manufacturer's recommendations, as this may prevent suction.
Clogged detergent filter: The EPW2-ST5.5 cleaner is equipped with a detergent filter that must be inspected and cleaned before each use. A partially or completely clogged filter blocks detergent suction. Remove the detergent filter (cross-shaped part at the top cap) and clean it with a soft brush or a pointed object (paperclip) to remove residues.
Clogged bottle suction hose: Inspect the hose connecting the bottle to the top cap to determine if there is a blockage (dried residues, impurities). Clean the hose by rinsing it with clear water or using a thin object to remove any blockage.
Insufficient water flow: The detergent is only drawn if the water flows with sufficient pressure. Check that the water supply tap is fully open, that the inlet hose is not bent or compressed, and that you have pressed the trigger to operate the machine.

If after these checks the detergent is still not being drawn, the detergent filter may be defective or damaged. You can obtain a replacement detergent filter (reference: cross-shaped filter ST3,5x30) from STERWINS customer service. The internal circuit of the cleaner may also have a blockage requiring professional intervention.

Question 9

How to adjust or control the tension of the drive belt of the STERWINS PLM2-46B150 lawn mower?

Accepted Answer

Although the official manual for the STERWINS PLM2-46B150 lawn mower states that any malfunction of the belt (part 10 of the exploded view) should be repaired by an authorized service center, you can perform a regular check of the condition and tension of this drive belt to extend its lifespan and maintain optimal traction.

How to check the belt tension: Locate the drive belt that connects the engine to the traction box. Press firmly in the center of the belt with your finger (engine off): it should flex about 3 to 5 mm under pressure. If the belt remains rigid or flexes excessively (more than 15 mm), this indicates a tension problem requiring intervention.

Signs of a worn or damaged belt: A problematic belt manifests as insufficient traction (the mower does not move forward or moves in jerks), squeaking or unusual noises, a burning smell, or a visibly cracked, frayed, or dusty belt. Do not confuse this with a problem with the traction control cable (located on the handlebar) which can also cause traction failure.

Preventive maintenance: Regularly inspect the belt before each mowing season and after prolonged use. Ensure that the belt guard (part 14 of the exploded view) remains clean and intact. Clean grass debris around the belt, as accumulation can reduce traction efficiency. A new belt stretches slightly during the first hours of use: readjustment may be necessary after the first 5 mowings.

What to do in case of a problem: If you notice that the tension is abnormal, that the belt is visibly damaged, or that traction is failing despite a properly adjusted control cable, immediately contact an authorized STERWINS customer service center. Do not attempt to adjust or replace the belt yourself, as this falls under specialized maintenance according to the manual. Replacement belt kits are available from authorized dealers such as Spareka (reference 077K246B150.53 for this model).

You can also consult the Briggs & Stratton 625EXi engine manual provided with your mower, which contains detailed information on the maintenance of the transmission and traction system. Regular and preventive maintenance helps keep your mower in good working condition and extends its lifespan.

Question 10

What should I do if the height adjustment lever does not stay in position?

Accepted Answer

On the STERWINS PLM2-46B150 lawn mower, the height adjustment lever (item 6) must remain locked in one of the 7 predefined positions (from 25 to 75 mm). If the lever does not stay in place and moves up or down by itself, it is usually due to loosening of the mechanical elements that hold it in place.

Checks and solutions:

Tighten all nuts and screws - The manual recommends checking that "all nuts and screws are properly tightened" before any use. Start by tightening the locking screw of the lever and all connections near the adjustment bar (item 65) and the adjustment plate (item 62).
Check the condition of the torsion springs - The locking mechanism uses torsion springs (item 66). A worn, broken, or misaligned spring would prevent the lever from locking. Inspect them visually.
Work on flat ground, engine off - For any adjustment or diagnosis, place the mower on perfectly flat ground and ensure that the engine is completely off and cold.

If tightening the screws and checking the springs do not resolve the issue, an internal component (broken spring, worn stop notch) may need replacement. In this case, consult an authorized STERWINS repairer.
