How to resolve a power loss on the Husqvarna LC48V lawn mower?
Frequently Asked Questions - 18/04/2026
Response Notice-Facile

A power loss on your Husqvarna LC48V lawn mower can be due to several causes. Here are the main checks and actions to take to restore your device's performance:

1. Check the air filter

A clogged air filter limits the airflow necessary for the engine to function properly. Check its condition and clean or replace it if necessary.

2. Check the spark plug

A worn or dirty spark plug can cause poor ignition and reduce power. Inspect the spark plug, clean it, or replace it if it is defective.

3. Use fresh and suitable fuel

Old or contaminated fuel can lead to poor combustion. Fill the tank with fresh fuel of the quality recommended by the manufacturer.

4. Examine the blades

Dull or damaged blades reduce cutting efficiency and can give the impression of a power loss. Sharpen or replace the blades if necessary.

5. Clean the exhaust system

A blocked exhaust by debris or soot can limit gas exit and affect power. Check and clean the exhaust.

6. Ensure proper engine cooling

An overheated engine can lose power. Check that the cooling fins are not blocked by grass or debris and ensure proper ventilation.

By applying these tips, you should be able to identify and resolve most causes of power loss on your Husqvarna LC48V mower.

Basic mowing technique

HUSQVARNA LC48V - Basic mowing technique - 1

WARNING! Make sure that your hands and feet do not come near the cutting attachment when the engine is running.

General

  • Mowing slopes can be dangerous. Do not use the lawn mower on very steep slopes.
  • The lawn mower should not be used on inclines greater than 30 degrees.
  • On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it.
  • Branches, twigs, stones, etc. should be removed from the lawn before you start to mow.
  • Never lift up the lawn mower or carry it around when the engine is running. If you must lift the lawn mower, first switch off the engine and disconnect the ignition lead from the spark plug.
  • Make sure the cutter does not hit foreign objects such as stones, roots or the like. This can make the cutter dull and bend the engine shaft. A bent axle gives imbalance and heavy vibration, which results in a great risk of the cutter becoming loose.
  • If any foreign object is hit or if vibrations occur stop the machine immediately. Disconnect the HT lead from the spark plug. Check that the machine is not damaged. Repair any damage.
  • Never mow more than 1/3 of the length of the grass. This especially applies during dry periods. Mow first with the cutting height set high. Then check the result and lower to an appropriate height. If the grass is really long, drive slowly and mow twice if necessary.

HUSQVARNA LC48V - General - 1

  • Never run with the machine when it is running. You should always walk with the lawn mower.

WARNING! The muffler gets very hot in use and remains so for a short time afterwards. Do not touch the muffler if it is hot!

If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.5mm . The spark plug should be replaced after about a month in operation or earlier if necessary.

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.

Muffler

The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material.

Regularly check that the muffler is securely attached to the machine.

Never use a machine that has a faulty muffler.

WARNING! Always wear heavy-duty gloves when repairing the cutting attachment. The blades are very sharp and can easily cause cuts.

It is important to have a sharp and correctly balanced cutter. Loosen the bolt holding the cutter and leave the cutter at a service workshop at least once a year for grinding and balancing. An appropriate time to do this is after the mowing season has finished.

If the cutter or cutter bracket need to be changed you must replace the cutter bolt, washer and cup spring at the same time.

The bolt should be tightened with a torque of 45-60 Nm when you fit the cutter again. See instructions under the heading Assembly.

If the cutter hits foreign objects such as stones, roots or the like the cutter will slip against the cutter bracket. This may mean that the contact surface of the cutter bracket appears slightly worn, which is completely normal. This is a safety device, which reduces the risk of the engine shaft becoming bent.

Changing the oil

The engine oil should be changed each year and every 25 working hours.

When changing the oil proceed as follows:

  • Empty the fuel tank by running the machine until the tank is empty.
  • Disconnect the HT lead from the spark plug.
    Unscrew the bolt holding the cutter.

  • The oil can be drained from the underside by loosening the oil plug. Do not forget to refit the oil plug before filling with oil again.
    Ask where you can dispose of surplus engine oil at your local petrol station.
  • Fill with new engine oil of a good quality. See the Technical data section.
  • Check the oil level with the dipstick on the oil filler cap.
  • The oil filler cap must be completely screwed down to give a correct picture of the oil level. If the oil level is low, fill using engine oil up to the upper level on the dipstick.
