GMD44 _760001 _xxxxxx Safety instructions Introduction The machine must only be operated, maintained and repaired by qualified persons who are familiar with the machines' operation and understand safety regulations and procedures for preventing accidents. The operator must follow the safety instructions in this manual and in the warnings posted on the machine.
Page 5
Before starting work, the operator must be familiar with all machine controls, handling devices and their functions. It is too late to learn once work has been started! Never let anyone operate the machine who is not trained to do so. Precautions to be taken before carrying out any operations on the machine ../../Illustrations/59900400-34.eps.png Before leaving the tractor or before adjusting,...
Page 6
Tractor handling, stability, performance and braking efficiency are all affected by weight distribution, trailed or mounted implements, additional ballast and driving conditions. It is therefore of great importance that the operator exercises caution in every given situation. Drive speed must be adapted to ground conditions as well as to roads and paths.
Page 7
Gross weight and weight per axle Check that the tractor's authorized gross weight as well as its lift capacity and maximum weight per axle are not exceeded. The front axle load (1) must never, under any circumstances, be less than 20% of the tractor's unladen weight.

accidents. Regularly check the hydraulic hoses. In case of normal wear, replace the hydraulic hoses every 5 years. Damaged or worn hoses must immediately be replaced. When replacing the hydraulic hoses, only use hoses with the specification recommended by the manufacturer of the machine. To locate a leak, use appropriate means.

If the primary PTO shaft is equipped with a torque limiter or a free wheel, these must be fitted on the machine side. Ensure that the PTO shaft is always correctly fitted and locked into place. Before connecting the PTO shaft, ensure that the PTO speed (rotational frequency) and direction of rotation are in line with the machine manufacturer's recommendations.

A hydro-pneumatic accumulator contains nitrogen under pressure (risk of suffocation in closed rooms). Repairs, maintenance or commissioning may only be carried out by competent persons. Wait for the accumulator to cool down before handling it. Only use nitrogen to precharge it. Depressurize the gas and fluid sides of the hydraulic accumulator before opening it.
Page 12
Do not solder, weld or use a blow torch near fluids under pressure or flammable components. For your own safety and for correct machine operation, only use original manufacturer parts. It is strongly recommended to have your machine checked by your Kuhn dealer after each season, especially tools and their attaching hardware.
Page 13
Immediately replace any worn, damaged or missing cutting tool or element. To do this, use the tool outfit supplied with the machine. For your safety, only use genuine KUHN parts ! Regularly check the condition of the protection covers. Immediatly replace any worn, damaged or missing cover.

place. Keep all persons and animals away from the danger zone. Stay a safe distance from the Gyrorake when rotors are moving. Never work in reverse. After disengaging the PTO drive, cuttings tools can continue rotating for some time. Stay away from the machine until all moving parts have come to a complete standstill.
Page 15
Before engaging the pto drive, lower the shredder onto the ground. For your safety, only use genuine KUHN parts ! Regularly check the condition of the guard plates/covers. Make sure all the guards are in place. Keep all persons and animals away from the danger zone.
