Husqvarna Rider 320 AWD Manual Do Utilizador

20 – 

English

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

For recommended spark plug, see Technical data.

1

Remove the ignition cable shoe and clean around the 
spark plug.

2

Remove the spark plug with a 3/4” (19 mm) spark plug 
socket wrench.

3

Check 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.

4

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

5

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

6

Tighten the spark plug, once it touches the seating, with 
the spark plug spanner. 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.

7

Replace the ignition cable shoe.

The Rider is equipped with a safety system that requires 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.

The main fuse is placed in a detachable holder under the 
battery case’s cover, in front of the battery.

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.

The tyre pressure should be 60 kPa (0.6 bar / 9 PSI) all round. 
To improve driving the pressure on the rear tyres can be 
reduced to 40 kPa (0.4 bar/5.6 PSI). The maximum tyre 
pressure is 100 kPa (1,0 bar/14 PSI).

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

Open the engine cover.

Check that the cooling intake is free from leaves, grass and 
dirt.

Check the air duct, located on the inside of the engine cover, 
ensure it is clean and does not rub against the cooling air 
intake.

A blocked cooling intake will interfere with the cooling of the 
engine, which can damage the engine.

IMPORTANT INFORMATION
Fitting the wrong spark plug type can damage the engine.

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.

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

Different tyre pressures on the front tyres will result in the 
blades cutting the grass at different heights. Having the 
same air pressure in the tyres is important in order to 
achieve the best possible performance as well as to avoid 
damage to the machine
