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 mower deck is disengaged.
• the steering controls are in the outer, locked
neutral position.
• the park brake is on.
Make daily inspections to ensure that the safety
system works by attempting to start the engine
when one of the conditions is not met. Change
the conditions and try again.
24
If the machine starts when one of these
conditions is not met, turn the machine off and
repair the safety system before using the machine
again.
Make sure the engine stops when the park brake
is not engaged and the operator leaves the
seated position.
Check that the engine stops if the mower blades
are engaged and the driver temporarily moves off
the driver's seat.
Tire Pressures
All tires should be at 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION DO NOT add
a tire liner or foam fill material to the tires.
Excessive loads created by foam filled tires will
cause premature failures.
Only use O.E.M. specified tires.

Park Brake

Visually check that no damage is found on the
lever, links, or switch belonging to the park brake.
Perform a standstill test and check that there is
sufficient braking action.
To adjust the park brake, contact the Husqvarna
service workshop.
WARNING! Faulty adjustment will result
in reduced braking ability and can cause an
accident.
