1.1 IMPORTANT ______________________________________________________________
The Jacobsen GA580 is a PTO driven aerator. The aerator must be attached to a suitable tractor.
If you follow all instructions in this manual, you increase the life of your aerator and keep its maximum performance.
Adjustments and maintenance must always be done by an approved technician.
IMPORTANT: Do the maintenance included in this manual to make sure that the quality is kept at a high level.
This Technical MANUAL is part of the aerator and must stay with the aerator always. Suppliers of both original and
used aerators need to keep the documentation that comes with the aerator.
You must use the aerator to aerate the turf and not for any other purpose. Compliance with the conditions of operation,
service and repair specified by the manufacturer, are understood to be part of the correct use.
ALL operators MUST read through this manual and understand the Safety Instructions, operation, lubrication and
maintenance procedures.
Make sure that you obey all safety and road traffic regulations.
You must not make any changes to the aerator that the manufacturer does not approve. This type of change can
release the manufacturer from the liability for any damage or injury.
When you discard worn parts, know the environmental result and use the systems available in the country where the
aerator is used. When the aerator is at its end of life, there are guidelines in this manual for the removal of the aerator
from use.
Use only Jacobsen approved parts.

1.4 GUIDELINES FOR THE DISPOSAL OF SCRAP PRODUCTS _______________________
1.4.1 DURING SERVICE LIFE _____________________________________________________
If a fluid leaks, contain the spill to make sure that the leak does not flow into the ground or drainage system. Follow the
local laws to make sure that leaks are controlled safely.
The maintenance procedures in this manual make sure that the damage that the aerator can cause in the local
environment is controlled safely.
Take these actions after the aerator complete its full service life.
1.4.2 END OF SERVICE LIFE _____________________________________________________
Use these guidelines with applicable Health, Safety and Environmental laws. Always use the approved local waste
disposal and agencies for recycled materials.
• Park the aerator in a location to use all of the necessary lifting equipment.
• Use the correct tools and Personal Protective Equipment (PPE) and take instruction from the technical manuals
applicable to the aerator.
• Disassemble the structure of the aerator and refer to the technical manuals. Give attention to parts that have
mechanical pressure or tension applied to the part in the aerator, including springs.
• Separate items that continue to have service life and returned to storage.
• Separate items that are worn into the material groups and removed according to the agencies for the recycled
materials that are available. Common types are as shown:
• Steel
• Non ferrous metals
• Aluminum
• Brass
• Copper
• Plastic Materials
• Identified
• Can be recycled
• Can not be recycled
• Not Identified
• Rubber
• Add items that can not be easily separated into different materials to the “General discarded materials” area.
• Do not burn the discarded materials
Change the aerator records to show that the aerator is not in service and is discarded. Supply this serial number to
Jacobsen Warranty Department to close their records.
