Engine Stop Key; Pre-Drive Inspection - Joyner JNSZ650DLB Owner's Manual And Parts Manual

Each time prior to starting the engine, check the throttle assembly to
ensure that when pedal is pushed all the way forward the assembly is
working smoothly and returns to idle when released. Do not operate if
pedal or engine throttle linkage fail to return to idle. If unable to correct
the problem through lubrication, adjustment or replacement of worn
parts, contact your dealer for assistance.
Before you start the engine, check that the parking brake is engaged,
and the gear shift lever is in neutral. Trying to start the engine in gear may
damage the starter motor, clutch or gearbox.
Release the key at once if the engine starts. Holding the key in start
position when the engine is running will cause damage to the starter
motor.
If the engine does not start after 10 seconds, a second attempt to start
the engine can be allowed. Improper operation will damage the engine.
