Break-In Time; Safety-Interlock System - Toro Titan ZXM4875 Operator's Manual

Break-In Time

New engines take time to develop full power. Mower decks and drive systems have higher
friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in
time for new machines to develop full power and best performance.

Safety-Interlock System

The safety-interlock system is designed to prevent the engine from starting unless:
• The blade-control switch (PTO) is disengaged.
• The motion-control levers are in the P
The safety-interlock system also is designed to shut off the engine whenever the control
levers are out of the P
If the safety-interlock switches are disconnected or damaged, the machine could
operate unexpectedly, causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches daily and replace any damaged
switches before operating the machine.

does not operate as described below, have an Authorized Service Dealer repair the safety
