Husqvarna 13C ユーザーズマニュアル

26 – 

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 5/8” (16 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 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.

Fitting the wrong spark plug type can damage the engine.

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.
