Question 1

HUSQVARNA 500 HD56 EL mower not cutting: why and how to fix it?

Accepted Answer

If the motor of your HUSQVARNA 500 HD56 EL mower is running but the machine is not cutting, here are the points to check:

1. Check for blade blockage and dirt

First, turn off the device and unplug it. Inspect the blades (length 560mm) for any stuck branches or debris. Remove any obstacles, then clean the blades with a dry cloth or brush.

2. Check blade lubrication

The blades should be lubricated with an eco-friendly lubricant after each use, according to the manual. A dry or poorly lubricated blade will not cut properly, even if the motor is running. Apply the recommended lubricant to the blades and let it sit for a few minutes before trying again.

3. Check branch thickness

The maximum cutting thickness of this device is 22mm. If you are trying to cut thicker branches, the mower will not be able to slice them. Ensure you are trimming within the capacity limit.

4. Inspect the blades for damage

Visually examine the blades for any damage, cracks, or worn areas. If the blades are visibly damaged or dull, note that this device cannot be sharpened by you (the design includes a safety cam). Only an authorized HUSQVARNA repair shop can replace the blades.

5. Check the cable and connections

Before each use, inspect the power cable for any signs of damage. Ensure the connection is correct and that the cable is not damaged.

If after these checks the blades are clean, well-lubricated, undamaged, and you are trimming within the 22mm limit, but the mower still does not cut, there may be an internal transmission problem. In this case, an authorized HUSQVARNA repair shop will be necessary.

Question 2

Why is fuel coming out of the exhaust of the HUSQVARNA 122HD60 hedge trimmer?

Accepted Answer

If fuel is leaking from the exhaust of your 122HD60, it indicates a problem with the 2-stroke engine that must be corrected before use.

Main causes:

Incorrect fuel mixture. The engine of the 122HD60 requires a precise mixture: 1:50 with Husqvarna oil, or 1:33 with a JASO FB/ISO EGB approved oil. An incorrect ratio causes unburned gasoline to accumulate and escape through the muffler.
Clogged carburetor. A blocked air filter or carbon deposits force the engine to run with a mixture that is too rich, expelling liquid fuel through the exhaust.
Dirty spark plugs. Replace the spark plug every month of regular use. A fouled plug prevents proper combustion.
Blocked exhaust system. The 122HD60 has a muffler with a catalytic converter. Check that the spark arrestor (on catalytic models) is not blocked.

Actions to take:

Check the mix ratio: first pour in half of the gasoline, then all the oil, shake well, then pour in the rest of the gasoline. Do not prepare more than a month's worth of fuel in advance.
Clean the air filter every 25 hours of use.
Replace the spark plug monthly if used regularly.
If the problem persists after these checks, contact an authorized Husqvarna workshop - a carburetor adjustment may be necessary.

Important: Never start the machine if there is spilled fuel. The muffler with a catalytic converter emits very hot gases that can cause a fire.

Question 4

Why won't my HUSQVARNA Aspire H50P4A hedge trimmer turn on?

Accepted Answer

If your hedge trimmer won't turn on, here are the solutions to check in order:

1. Check the battery

Make sure the P4A 18-B45 battery is properly installed and charged.
If the LED is off or flashing red, the battery may be too low or experiencing thermal overload. Fully recharge it with the P4A 18-C50 or P4A 18-C70 charger.
Check the temperature: charging should be done between 0 °C and 35 °C. If the battery is too cold or too hot, wait before recharging.

2. Correct starting procedure

The hedge trimmer uses a three-step ignition procedure:

Step 1: Press the ON/OFF button and hold it down until the green LED lights up. This is not a simple click; you must hold the button.
Step 2: Press the trigger on the front handle.
Step 3: Press the power trigger to start the blades.

3. Check the LEDs

Solid green LED: battery OK and ready to operate.
Flashing green LED: low battery, urgent recharge needed.
Flashing red LED: motor overload or thermal issue. Release the accessory and let it cool for a few minutes before trying again.
No LED: battery not detected or not charged at all.

If after these checks the hedge trimmer still does not start, contact HUSQVARNA support or the point of sale.
