WARNING

Incorrect installation of the blade or components used to retain the blade can be dangerous. Failure to use all original components and assembled as shown could allow a blade or blade component to be thrown out from under the deck resulting in serious personal injury or death.

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 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.

2. 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 initiate shutdown after approximately 1/2 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.

Note: If machine does not pass any of these tests, do not operate. Contact your authorized EXMARK

SERVICE DEALER.
