Husqvarna Essential Lawn Mower Tire Pressure and Maintenance for Optimal Performance
Page 22

Maintenance

Checking the Tire Pressure

The tire pressure should be 60 kPa / 0.6 bar / 8,7 PSI on all wheels. In order to improve traction, the pressure in the rear tyres can be reduced to 40 kPa / 0.4 bar / 6 PSI.

IMPORTANT INFORMATION Different tire pressures on the front tires will result in the blades cutting the grass at different heights.

Ignition system

The engine is equipped with an electronic ignition system. Only the spark plug requires maintenance.

For recommended spark plug, see Technical data.

IMPORTANT INFORMATION

Fitting the wrong spark plug type can damage the engine.

Replacing the spark plug

1Remove the ignition cable boot and clean around the spark plug.

2Remove the spark plug with a 5/8” (16 mm) spark plug socket wrench.

3Check the spark plug. Replace the spark plug if the electrodes are burned or if the insulation is cracked or damaged. Clean the spark plug with a steel brush if it is to be reused.

4Measure the electrode gap with a gapping tool. The gap should be 0.75 mm/0.030”. Adjust as necessary by bending the side electrode.

5Reinsert the spark plug, turning by hand to avoid damaging the threads.

IMPORTANT INFORMATION

Inadequately tightened spark plugs can cause overheating and damage the engine. Tightening the spark plug too much can damage the threads in the cylinder head.

6Tighten the spark plug, once it touches the seating, with the spark plug socket wrench. Tighten the spark plug so that the washer is compressed. A used spark plug should be turned 1/8 of a turn from the seated position. A new spark plug should be turned a 1/4 turn from the seated position.

7Replace the ignition cable shoe.

IMPORTANT INFORMATION

Do not turn over the engine if the spark plug or ignition cable has been removed.

Fuses

The main fuse is placed in a detachable holder behind the battery under the protective cover.

Type: Flat pin, 15 A.

Do not use any other type of fuse when replacing.

A blown fuse is indicated by a burnt connector. Pull the fuse from the holder when replacing.

The fuse is there to protect the electrical system. If it blows again shortly after replacement, it is due to a short circuit, which must be fixed before the machine can be put into operation again.

Check the safety system

The machine is equipped with a safety system that prevents starting or driving under the following conditions.

The engine can only be started when:

•The cutting deck is raised and the parking brake is applied.

The engine should stop when:

•The cutting deck is lowered and the driver rises from the seat.

•The cutting deck is in its raised position, the parking brake is not applied and the driver rises from the seat.

Check daily to ensure that the safety system works by attempting to start the engine when one of the conditions above is not met. Change the conditions and try again.

Checking the engine’s cooling air intake

Clean the air intake grille in the engine cover behind the driver’s seat.
