Operation
Drive Wheel Release Valves
Located on the top left front corner of hydrostatic pumps.
Drive wheel release valves are used to release the hydrostatic drive system to allow the machine to be pushed without the engine running. Tilt seat up to gain access to pumps.
With a 7/16 wrench, turn both valves one turn counterclockwise to release drive system. Turn clockwise to reset system. Do Not overtighten. Do
Not tow machine.
Tracking Adjustment Knob
Located under the seat on the left pump control link.
Rotating this knob allows fine tuning adjustments so that the machine tracks straight with the drive levers in the full forward position.
Run unit at 3/4 speed for at least 5 minutes to bring hydraulic oil up to operating temperature. Stop machine and wait for all moving parts to stop. Engage park brake. Tilt seat forward to gain access to the tracking knob. Rotate the knob towards the right to steer right and rotate towards the left to steer left. Adjust in 1/8 turn increments until the machine tracks straight. Check that the machine does not creep when in neutral with the park brakes disengaged.
Important: Do Not rotate the knob too far, as this may cause the machine to creep in neutral. Refer to the Motion Control Linkage Adjustment section in Maintenance.
PTO Engagement Lever
Located immediately left of the left console.
Lever must be moved up to the “ROTATE” position to engage the PTO and blower drives. Lever is moved down to the “STOP” position to stop the drives.
Engine Oil Temperature Light and Buzzer
Located on the right console.
The engine oil temperature light monitors the temperature of the engine oil. An illuminated engine oil temperature light and intermittent buzzing sound signals the engine is overheating.
Pre-Start
Fill fuel tanks. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher. Regular grade leaded gasoline may also be used; however, combustion chamber and cylinder head will require more frequent service. See Engine Owner’s Manual.
Do Not add oil to gasoline.
Do Not overfill fuel tank. Never fill the fuel tank so that the fuel level rises above a level that is 1/2 inch (13 mm) below the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage.
Make sure you understand the controls, their locations, their functions, and their safety requirements.
Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.
