locked to the tractor PTO and gearbox shafts. Drive shields must turn freely on the drive- line.

•See that all shields are correctly installed.

•Remove any debris caught in the rotors.

•Check gearbox oil level before first operation and every 200 hours of operation thereafter. (Refer to operator maintenance section.)

MAINTENANCE SAFETY

•Never attempt to clean, adjust, lubricate or perform any maintenance on the AERA-vator while it is attached to the tractor or any other power source with the engine running.

•Read and understand all safety decals prior to performing any maintenance. Replace any safety decals that are not legible.

•Never attempt to clean, adjust, lubricate or perform any maintenance on the AERA-vator while it is attached to the tractor in the raised position unless safety blocks are inserted un- der the frame.

•When not attached to the tractor, always use the lifting hook to hoist the machine for maintenance. (See Figure 4). Use ex- treme caution when using lifting hook be- cause center of gravity is affected by ad- ditional attachments and the unit may shift rearward.

•When installing tines, performing any ro- tor shaft service, or removing debris from the rotors, ensure that the rotor shaft does not rotate because a serious pinch injury could occur.
