| Poorly tightened or damaged spring in the break-back device| Check and adjust the spring tension; replace if damaged
Local bumps, e.g. hardened molehills| Reduce speed, and tilt the cutting unit backwards

Disassembly, utilization and environment protection

Protect your hands (and body) against injuries, and the harmful effects of lubricants and oils.
Use protective gloves and tools which are in good mechanical condition.
Machine elements, which when dismounting can move or rotate, must be properly secured.
Worn or damaged parts removed during repair (disassembly) should be stored in a separate location, with a limited access for persons and animals. Worn out metal parts must be delivered to the scrap metal collection points. Worn out plastics must be delivered to the chemical waste collection (utilization) points.
When filling up or replacing the oil, avoid its spillage. Store the waste oil in sealed containers, and periodically deliver it to the special collection (utilization) points.
Abandoned parts or machine components, and spilled oil, may pose a risk of accident, cause an environmental pollution and violate applicable laws.

Spare Parts Catalogue

9.1. How to order spare parts
Each order form should include the following:

• address of the buyer,
• exact shipping address (place where machine is located or other means for delivery collection),
• terms of payment,
• serial number and year of production of the mower (according to the plate located on the machine),
• spare part number,
• spare part name,
• number of parts ordered.

Spare parts must be ordered at the points of sale of the machines or from the distributor.
Use only the original spare parts provided by the distributor to guarantee safe and reliable operation of the machine. The use of unoriginal spare parts or parts, which have been repaired, will void the warranty.
