Rotating this knob allows ne 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

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

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.

Pre-Start
Fill fuel tanks. For best results use only clean, fresh
regular grade unleaded gasoline with an octane rating
of 87 or higher.
Important: Never use methanol, gasoline
containing methanol, gasohol containing more
than 10% ethanol, premium gasoline, or white
gas because the fuel system could be damaged.
Do Not add oil to gasoline.
Do Not overll fuel tank. Fill the fuel tank to the
bottom of the ller neck. The empty space in the
tank allows gasoline to expand. Overlling may result
in fuel leakage or damage to the engine or emission
system (if equipped).
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.
