Gradually squeezing the left or right hand drive lever disengages the wheel drive
belts, causing the left hand or right hand wheel to slow down until they reach
neutral or stop. This makes the machine turn to the left or right respectively.
Squeezing further engages the park brakes. The sharpness of the turn varies by
how much the lever is squeezed. For straight ahead motion, smoothly release
both drive levers to engage both drive wheels simultaneously.
4.1.3 Neutral Lock/Parking Brake Latch: Located at the end of the handles. The purpose
of these latches is to allow the operator to lock the drive levers in a "neutral" position
where neither the wheel drive belts nor the brakes engage, or in a "park brake"
position where the wheel drive belts are not engaged and the park brake is
engaged. (See Figure 9).
Apply parking brakes whenever leaving the operators position.
NEUTRAL LOCK/PARK BRAKE LATCH
4.1.4 PTO Engagement: Located on the left side of the upper handle.
To engage the blades, push the lever forward, or away from the operator, until the
linkage locks over-center.
To disengage the blades, pull the lever to the rear, or towards the operator.
4.1.5 Choke Control: Choke is used to aid in starting a cold engine.
The choke control is located on the front left corner of the fuel tank support and is
activated by pulling the control outward. Once the engine has started move the
choke control to the "OFF" position. DO NOT run warm engine with the choke in
the "ON" position.
4.1.6 Throttle Control: Located on the control console's right side. The throttle is used to
control engine speed. Moving the throttle control forward will increase engine
speed and moving it to the rear will decrease engine speed.
4.1.7 "Off-Run" Switch: Located on the console. Turn key to the "Run" position to allow
the engine to be started. Turn key to the "Off" position to shut engine off.
4.1.8 Fuel Shut-Off Valve: Installed in the fuel line midway between the tank and the
engine. The fuel shut-off valve is used to shut off the flow of fuel when parking
inside a building, during transportation to and from the job sites, and when the
machine will not be used for a few days.
Rotate valve 1/4 turn clockwise to shut fuel off. Rotate valve 1/4 turn counter-
clockwise to turn fuel on.
