WARNING
This machine is equipped with an interlock
system intended to protect the operator and
others from injury. This is accomplished by
preventing the engine from starting unless the
deck drive is disengaged, the steering control
levers are in the neutral position and the operator
is in the seat. The system shuts off the engine if
the operator leaves the seat with the deck drive
engaged and/or the steering control levers are not
in the neutral position and the parking brake is
not engaged. Never operate equipment with the
interlock system disconnected or malfunctioning.
18. Test the operation of the safety interlock system.
See Section 2.6.
19. Be sure the interlock switches are functioning
correctly.
2.6 TESTING THE SAFETY INTERLOCK
SYSTEM
The safety interlock system should be tested each time
before using the machine. If the safety interlock system
does not operate as described below, contact your local
Authorized Scag Power Equipment Dealer immediately to
have the safety interlock system repaired.
1. Sit in the seat in the operating position, engage the
parking brake, place the steering control levers in
the neutral lock position, and engage the PTO switch
to the ON (up) position. Try to start the engine; the
engine should not start
2. Sit in the seat in the operating position, engage the
parking brake, move the PTO switch to the OFF
(down) position, move either of the steering control
handles out of the neutral lock position. Try to start
