Frequently Asked Questions - W25PEN HUSQVARNA

What fuel should I use for the Husqvarna W25PEN pump?

Use a mixture of unleaded gasoline (octane rating min. 90 RON, max 10% ethanol) and air-cooled 2-stroke engine oil. The mixing ratio is 25:1 or 50:1 if using original Husqvarna oil.

How to start the engine cold?

Press the air purge 10 times, set the choke to closed position, pull the cord slowly until resistance then pull sharply until the engine coughs. Then set the choke to open position and pull again to start. Let it warm up for 60 seconds at low speed.

How to stop the pump in an emergency?

Press the stop switch (ON/OFF switch) to cut the engine ignition.

What periodic maintenance is recommended?

Every 25 hours: clean the air filter and fuel filter, check the spark plug gap (0.6-0.7 mm). Every 100 hours: clean the muffler. Consult the complete schedule in the manual.

What to do if the engine does not start?

Check the spark plug (dirty or wet), fuel (correct mixture and full tank), choke and purge. If the engine is flooded, set the choke to open and pull the cord at full throttle to expel excess fuel.

How to fill the pump chamber with water before use?

Remove the pump chamber cap, fill with water up to the discharge outlet level, then close the cap. This step is mandatory to avoid damaging the pump.

What is the maximum suction height?

The suction height must not exceed 7.5 m (25 feet). For optimal operation, keep the level difference as low as possible.

Can I use the pump with chemicals?

Yes, it is designed for spraying pesticides and herbicides. Follow local regulations and wear personal protective equipment (gloves, goggles, boots).

How to store the pump for a long period?

Empty the fuel tank, start the engine until it stops from lack of fuel. Remove the spark plug, pour a few drops of 2-stroke oil into the cylinder, pull the cord 2-3 times, then reinsert the spark plug. Store in a dry place away from moisture.

What to do if the pump flow is low or zero?

Check that the suction hose is not damaged, that the strainer is submerged and clean, that the connections are tight, and that the pump chamber is filled with water. Make sure the suction height is not too high.

To use fuel

WARNING: This product has a two-cycle engine. Use a mixture of gasoline and two-cycle engine oil. Make sure to use the correct quantity of oil in the mixture. Incorrect ratio of gasoline and oil can cause damage to the engine.

Gasoline

CAUTION: Do not use gasoline with an octane number less than 90 RON (87 AKI). This can cause damage to the product.

CAUTION: Do not use gasoline with more than 10% ethanol concentration (E10). This can cause damage to the product.

CAUTION: Do not use leaded gasoline. This can cause damage to the product.

• Always use new unleaded gasoline with a minimum octane number of 90 RON (87 AKI) and with less than 10% ethanol concentration (E10).
- Use gasoline with a higher octane number if you frequently use the product at continuously high engine speed.
• Always use a good quality unleaded gasoline/oil mixture.

Two-cycle engine oil

• Use only the two-cycle engine oil of high quality, especially HUSQVARNA two-cycle engine oil. Use only the oil of an air cooled engine.
  • Mixture ratio 50:1 (2%).
• Oil of low quality and high oil/fuel ratio can decrease the lifetime of catalytic converters.
• Check with the approved dealer when you select an oil.
• If Husqvarna two-stroke oil is not available, you can use another two-stroke oil of good quality that is intended for air cooled engines.
• Do not use the two-stroke oil for water-cooled outboard engines. The two-stroke oil is sometimes referred to as outboard oil.

MAINTENANCE

WARNING: Read and understand the safety chapter before you clean, repair or do maintenance on the product.

To stop the engine

• After every 25 hours of operation, please remove the air cleaner cover and inspect the air cleaner. If it is too dirty, wash it carefully in warm water containing a neutral detergent, and put it back to its original position after drying it thoroughly.
- If the air cleaner is distorted or damaged, please replace it with a new one.
- If the air cleaner is blocked, the efficiency of the engine will be reduced. In addition, the engine interior will suffer abnormal wear if it is operated without filter or if continually operated with a distorted or damaged filter.

To check the fuel filter

• After every 25 hours of operation, empty the fuel tank, detach the fuel filter from the tank, and remove all dirt. If the filter is too clogged, please replace it with a new one.
• If the fuel filter is clogged, the engine speed may be limited or speed fluctuations may occur.
• If the engine is operated without a fuel filter, dirt will accumulate in the carburetor and cause it to malfunction

To check the spark plug

• Do not touch the spark plug with your bare hands immediately after operation, as there is the risk of burns due to high temperature.
  • After every 25 hours of operation, detach the spark plug and remove dirt from the electrodes with a wire brush or similar.

• The correct electrode gap is 0.6 to 0.7mm.

• When replacing plugs, please use designated items.
• If too much fuel is absorbed or poor quality oil is used, the spark plug electrodes become dirty, making the engine harder to start.
• Note that using any spark plug other than those designated may result in the engine failing to operate properly or in the engine becoming overheated and damaged.
• To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench.

TIGHTENING TORQUE: 14.7 to 21.6 N.m.

(150 to 220 kgf-cm)

To check the fuel filter

WARNING: Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, stop using the machine and have it repaired immediately. Failing to do so may result in the engine catching on fire.

• Perform the procedures follows after every 100 hours of operation
• Remove the muffler, insert a screwdriver into the vent, and wipe away any carbon buildup. Wipe away any carbon buildup on the muffler exhaust vent and cylinder exhaust port at the same time.
• Tighten all screws, bolts, and fittings.
• Check and wipe off if any oil or grease left in between the clutch lining and drum with oil-free and lead-free gasoline.

To check the cooling system

WARNING: Never touch the cylinder, muffler, or spark plug with your bare hands immediately after stopping the engine. The engine can become very hot when in operation, and doing so could result in severe burns.

• When checking the product, check the area around the muffler and remove any staffs that attached, in case the muffler is overheated or even the engine catch on fire.
• Check the intake air cooling vent and the area around the cylinder cooling fins for blockage every 25 hours of use, in case of engine overheat or even product failure.
• Note that it is necessary to remove the upper cover and the lower cover in order to be able to view the upper part of the cylinder.

To adjust engine speed

- Although the engine is adjusted before leaving the factory, it may require readjustment or maintenance after repeated use. Please consult the original supplier regarding inspections and maintenance other than those shown below.

To adjust idle speed

Note: Warm up the engine before adjusting the idle speed.

• If the engine stops or the pump continues to work at idle speed with the throttle trigger at the turtle position, readjust the engine speed with the idle speed adjustment screw on the left of the carburetor.
  Turn the idle adjustment screw:
• Counter-clockwise to reduce engine speed
• Clockwise to increase engine speed
