Operator Weight Adjustment Control
Located on the left side of the control console (see
Figure 6).
This feature takes into account the weight of the
operator so that the correct aerating pressure and plug
length is achieved and to maximize lateral machine
stability. Rotating the control counterclockwise
decreases the pressure and rotating it clockwise
increases it (See Adjusting the Operator Weight
Control Setting).
Note: Each operator must adjust the system pressure
so that the drive tires lightly touch the ground.
Important: Keep the drive tires on the ground at
all times to maximize lateral machine stability.

Pre-Start

Fill fuel tank on level ground. See Fuel
Recommendations in the Specifications section for
additional gasoline information.
Do Not add oil to gasoline.
Do Not overfill fuel tank. Fill the fuel tank to the
bottom of the filler neck. The empty space in the
tank allows gasoline to expand. Overfilling may result
in fuel leakage or damage to the engine or emission
system.
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.
