Operation
Tines Ground Engagement Foot
Switch
Keep hands and feet away from the tines. Make
sure the tines area is clear of any obstructions
before lowering it.
Located on the operator platform (see Figure 5).
To lower the tines into the ground, stand on the
tine ground engagement switch. To raise the tines,
remove your foot from the switch.
Tine Down Pressure Control
Located on the left side of the control console (see
Figure 5).
Rotate the control counterclockwise to decrease the
pressure and the length of the aeration plug; rotate
clockwise to increase pressure and increase the length
of the aeration plug.
Tine Down Pressure Gauge
Located in the middle of the control console (see
Figure 5).
The gauge displays the tine down pressure when
aerating.
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.
Operating Instructions
Open the Fuel Shut-Off Valve
Rotate the valve and align with the fuel line to open.
Starting the Engine
1. Leave the motion control levers in neutral and
engage the parking brake.
2. Place the throttle midway between the “SLOW”
and “FAST” positions.
3. On a cold engine, push the choke lever forward
into the “ON” position. On a warm engine, leave
the choke in the “OFF” position.
4. Turn ignition switch to the “START” position.
Release the switch as soon as the engine starts.
Important:
Do Not crank the engine
continuously for more than ten seconds at a
time. If the engine does not start, allow a 60
second cool-down period between starting
attempts. Failure to follow these guidelines
can burn out the starter motor
5. If the choke is in the “ON” position, gradually
return choke to the “OFF” position as the engine
warms up.
Lowering the Tines
DANGER
The rotating tines under the engine deck are
dangerous. Tine contact can cause serious injury
or kill you.
Do Not put hands or feet under the unit when
the engine is running.
1. Set throttle to “MIDWAY” position.
2. Step on the tine ground engagement foot switch
to lower the tines. Stand on the switch and move
the motion control levers forward to aerate.
3. Adjust the throttle for the working conditions.
Adjusting the Tine Down Pressure
Adjust the plug depth by rotating the tine down
pressure control. Rotate the control counterclockwise
to decrease the hydraulic down pressure to remove a
shorter plug. Rotate clockwise to increase pressure
and pull a longer plug.
First time use: set the pressure to 350 psi (24 bar).
Ideal plug depth is 3-4 inches (7.6–10 cm). Rotate the
plug depth control to adapt to the soil conditions.
Keep the drive tires on the ground at all times.
