Operation
Note:
The foot rocker bar, located behind the
tine ground engagement foot switch, can be
adjusted for operator comfort. To adjust, loosen
the foot rocker bar hardware, slide the bar forward
or rearward, and retighten hardware.
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.
Raising the Tines
To raise the tines, remove your foot from the tine
ground engagement foot switch.
Important:
The tines are rotating when the
motion control lever is moved out of the neutral
position.
Stopping the Engine
1. Move the motion control levers back to the
neutral position and bring the unit to a full stop.
2. Lift your foot off of the tine ground engagement
foot switch control to raise the tines.
3. Place the throttle in the midway between the
“SLOW” and “FAST” positions.
4. Allow the engine to run for a minimum of 15
seconds, then turn the ignition switch to the
“OFF” position to stop the engine.
5. Engage the parking brake.
6. Remove the key to prevent children or other
unauthorized persons from starting the engine.
7. Close the fuel shut-off valve when the machine
will not be in use for a few days, when
transporting, or when the unit is parked inside
a building.
Driving the Machine
CAUTION
Machine can spin very rapidly by positioning one
lever too much ahead of the other. Operator may
lose control of the machine, which may cause
damage to the machine or injury.
• Use caution when making turns.
• Slow the machine down before making sharp
turns.
Important:
To begin movement (forward or
backward), the brake lever must be disengaged
(pushed forward) before the motion control
levers can be moved.
