Maintenance - BRADLEY MOWERS 48SC Owner's Manual & Parts List

CHECK DAILY
Operator Presence Interlock System 一 Start Operation
For the engine to crank, the parking brake must be ON, the PTO (blades) OFF. Stand on the operator
platform and check, one by one, if the engine will crank with the parking brake OFF or the PTO (Blades)
ON.
Operator Presence Interlock System 一 Run Operation
In order for the engine to run, the operator must either be standing on the platform, or walking behind the
unit with the platform up, the parking brake in the OFF position and the LH control handle held down out of
the neutral position.
The engine may also run if the parking brake is in the ON position, the LH control handle is in the
NEUTRAL position rotated up, and the PTO (blades) are OFF.
To check:
1. Start the engine and run at 1/2 throttle.
2. With the LH control handle in the NEUTRAL position rotated up, move the parking brake lever to OFF
and turn the PTO (Blades) ON. Each check should kill the engine after 1/2 second delay. (A 1/2
second delay is built into the system to prevent engine cut-out when traversing rough terrain.)
Repair machine before using if the Operator Presence Interlock System does not operate correctly in start
or run. Contact your authorized Bradley dealer.
