DRIVE LEVER, NEUTRAL LOCK/PARK BRAKE LATCH OPERATION
4.1.4 Operator Presence Control (OPC) Levers:
Located on the upper handle assembly directly above the handle grips. When
these levers are depressed, the OPC system senses that the operator is in the
normal operator's position. When the levers are released, the OPC system
senses that the operator has moved from the normal operating position and will
kill the engine if either the transmission shift lever is not in the neutral position or
the blade clutch is engaged.
4.1.5 Blade Engagement Lever:
Located on the left side of the upper handle. To engage the blades, push the
lever forward, or away from the operator, until the turnbuckle locks over-center.
To disengage the blades, pull the lever to the rear, or towards the operator, until
the bell crank, located at the rear of the engine deck, contacts the deck.
4.1.6 Throttle-Choke Control:
The throttle-choke control lever is located on the control console right side. Choke
aids in starting a cold engine. The choke control is a part of the throttle control and
activates by moving the throttle control lever to the full forward position. You will
notice a detent at the "full throttle" position (approximately 3/4" from top of slot)
continue pushing forward into the "choke" position.
Once the engine has started, move the throttle control lever to the midway point
and allow the engine to warm-up before going to full throttle.
All 12.5 HP Kawasaki, Kohler, and B&S 10.5 hp engines are equipped with
"throttle kill" as a standard feature. Moving the throttle control lever to the full rear
position will kill the engine. You will notice the control lever will fall into a detent
at the "idle" position, continuing rearward past this detent will shut off the engine
15 & 17 HP Kawasaki engines do not have "throttle kill". The key switch is turned
to the "Off" position to kill the engine.
"Off-Run" Switch (15 &17 HP Kawasaki only): Located on the console. Turn key
4.1.7
to the "Run" position to allow the engine to be started. Turn key to the "Off"
position to shut engine off.
