The operator should read the following pages carefully and become familiar with the contents before starting work. Familiarity with the instruction manual is an essential part of training for a competent user. - Page 14 8999129: v1 11/09/2018 DANGER! AVOID WIRE. It can be extremely dangerous if wire catches in the blades of the machine, and every care must be taken to ensure this will not happen. Inspect the working area before commencing. Remove all loose wire and obstructions and clearly mark those that are fixed so that you can avoid them.
- Page 15 8999129: v1 11/09/2018 DANGER! Operate the mower only with a tractor equipped with an approved ‘roll over protection system (ROPS). Always wear your seat belt.
