Checking The Safety System; Checking The Engine's Cooling Air Intake - Husqvarna WH4817E, WH3615E Operator's Manual

Checking 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:
1. The blades are disengaged.
2. The neutral bail must be in the locked
position.
Make daily inspections to ensure that the safety
system works by attempting to start the engine
when one of the conditions is not met.
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.
Functional check
Check the function of the safety electrical system on
a regular basis.
1. Engine must stop if blades are engaged without
operator presence levers held down.
2. Engine must stop if neutral bail is taken out of
neutral without holding down operator presence
levers.
3. Engine must not start unless blades are off and
neutral bail is in the neutral position.
WARNING!
Do not operate the mower if the
interlock safety system allows
operating or starting in any
unsafe condition.
Checking the Engine's Cooling Air
Intake
Check that the engine's cooling air intake is
free from leaves, grass, and dirt.
If the cooling air intake is clogged, engine
cooling deteriorates, which can lead to
engine damage.
