Controls
Become familiar with all the controls before you start the
engine and operate the aerator.
Traction Lever
To move forward, move the traction lever forward. To
move rearward, move the traction lever rearward
(Fig. 18).
The farther you move the traction control, the faster the
aerator will move.
To stop, release the traction control.
Parking Brake
To engage the parking brake, move the lever toward the
engine. To disengage the parking brake, move the lever
forward (Fig. 18).
Always set the parking brake when you stop the aerator or
leave it unattended.
Jog traction lever forward and reverse to release parking
brake.
Oil Pressure Warning LIght
The oil pressure warning light (Fig. 18) glows when oil
pressure in engine drops below a safe level. If low oil
pressure ever occurs, stop engine and determine the cause.
Repair the damage before starting the engine again.
Ignition Switch
The ignition switch (Fig. 19), which is used to start and
stop the engine, has three positions: OFF, RUN, and
START. Rotate key clockwise to the START position to
engage starter motor. When engine starts, release key and
it will move automatically to the ON position. To shut
engine off, rotate key counterclockwise to the OFF
position.
Raise, Lower/Engage Switch
Raise – Press the top of the switch (Fig. 18) to raise the
coring head. The engine must be running to generate lift
pressure. If the coring head is below the transport height,
refer to System Control Circuit Reset, page 24.
Lower/Engage – Press the bottom of the switch (Fig. 18)
to lower and engage the coring head. The traction lever
must be in the forward position to activate the switch.
Keep hands and feet away from the coring head.
Make sure the coring head area is clear of any
obstructions before lowering it.
Caution
To lower the coring head without engaging the coring
head, turn the ignition key to the RUN position (without
the engine running), move the traction lever to the
forward position and press the bottom of the switch.
