CAUTION
POTENTIAL HAZARD
♦ Operating a mower deck with loose or
weakened blade bolts can be dangerous.
WHAT CAN HAPPEN
♦ A loose or weakened blade bolt could
allow a blade rotating at a high speed to
come out from under the deck, causing
serious injury or property damage.
HOW TO AVOID THE HAZARD
♦ Always re-install original Exmark blades,
blade bushings, spring disc washers, and
blade bolts in the correct positions as
shown.
4.1.6 Check safety interlock system.
Service Interval: Daily
a) 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 neutral lock position - starter
must not crank.
Try to start with operator in seat, parking brake engaged, PTO engaged and
motion control levers in the neutral lock position - starter must not crank.
Try to start with operator in seat, parking brake engaged, PTO
disengaged, and the left motion control lever in, starter must not crank,
repeat again with the right lever in, then with both levers in - starter must
not crank.
b) Check the kill circuits. Run engine at one-third throttle, disengage parking
brake and raise off of seat (but do not get off of machine) engine must stop
after approx. 1/2 second has elapsed (seat switch circuit has a time delay
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 stop after 1/2 second has elapsed.
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 stop after 1/2
second has elapsed.
Again, run engine at one-third throttle, brake engaged, and move left
motion control lever in - engine must stop.
Repeat again moving the right lever in, then moving both levers in - engine
must stop whether operator is on seat or not.
NOTE: If machine does not pass any of these tests, do not operate.

IMPORTANT: It is essential that operator safety mechanisms be
connected and in proper operating condition prior to use for mowing.
