Fuses; Check The Safety System; Checking The Engine's Cooling Air Intake - Husqvarna Rider 115B Operator's Manual

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.
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.
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.
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.
Maintenance

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.
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.
!
WARNING! The cooling air intake rotates
when the engine is running. Mind your
fingers.
