Check Safety Interlock
System
Service Interval: Before each use or daily
Note:
To prevent engine cut-outs on rough terrain
the seat kill switch has a 1/2 second delay.
1. Check starting circuit. Starter
should
crank with,
parking brake
engaged
, PTO
disengaged
and
motion control levers moved out in the
neutral
lock
position. The operator does not need to be
in the seat to start the engine.
Try to start with
operator in seat
, parking brake
disengaged, PTO disengaged and motion control
levers in the

2. Check the kill circuits. Run engine at one-third
throttle,
disengage
parking brake and
raise off

second has elapsed (seat has time delay kill switch
to prevent cut-outs on rough terrain).
Run engine at one-third throttle,
engage PTO
and
raise off
of seat (but do not get off of
machine) engine
must initiate shutdown
after
one second has elapsed if the handles are in. The
delay will be 1/2 second if the handles are out.
Run engine at one-third throttle, with brake
disengaged, move levers in and raise off seat (but
do not get off of machine) engine must
initiate
shutdown
after 1/2 second has elapsed.
Again, run engine at one-third throttle, brake
engaged
, and move
left motion control lever
in
- engine
must initiate shutdown
after 1/2
second has elapsed.
Repeat again moving the
right lever in
, then
moving
both levers in
- engine
must initiate
shutdown
after 1/2 second has elapsed whether
operator is
on seat or not
.
