For your safety

General
These safety regulations must be observed when working with the machine. Read the entire instruction manual before using the machine for the first time. Keep the instruction manual in a safe Please also observe the instruction manual for the tiller – particularly the safety instructions in the “For your safety” section. The safety instructions contained in this instruction manual supplement the safety instructions in the instruction manual for the tiller.

Caution – risk of injury!
The ridger is intended for cutting furrows in the soil; its use for other purposes is not permitted. The ridger must only be installed on STIHL machines intended for this purpose. Information is available from your STIHL specialist dealer. Modifications or adaptations to the ridger are not permitted. Any modifications to the ridger will furthermore result in voiding of the warranty cover. Risk of injury when lifting the tiller! Installing a ridger increases the overall weight of the tiller and changes its centre of gravity.

Clothing and equipment
Always wear thick gloves when assembling, installing and removing the ridger as well as when working on the adjustment elements.

Transport
Before transporting the tiller (e.g. pushing, pulling, lifting), always remove the ridger and transport separately. Secure the ridger on a load floor using adequately dimensioned fastening materials (ropes, straps, etc.). In particular observe the instructions regarding transport in the instruction manual for the tiller.

Before initial operation
Make sure that all persons who use a tiller fitted with a ridger are familiar with the instruction manuals for the tiller and the accessory. In particular ensure that you ar  also familiar with all of the controls of the accessory. Install the ridger completely and properly on the tiller as described in this instruction manual. (6.1) Before using the ridger and tiller, always carry out a visual check to ensure that they are in good operating condition. All faulty, worn or damaged parts must be replaced before using the machine. Carefully inspect the complete area on which the machine is to be used and remove any large stones, sticks, wires, bones or other foreign objects which could be thrown up by the machine. Objects hidden in the ground (lawn sprinkler systems, posts, water valves, foundations, electrical wires, etc.) must be clearly marked before working with the machine and avoided during operation. Never run over any such foreign objects.

Working with your machine
Always ensure that you keep your feet and legs far enough away from the tiller and the installed ridger. Particular care is necessary when using reverse gear. Tillers with cast-iron wheels must be driven very slowly and with extreme care on paths or other hard surfaces. Control the speed of rotation of the cast-iron wheels using the throttle lever – set the engine to the lowest speed (see instruction manual for the tiller).

General recommendations

Recommendations for working with the ridger
The ridger can be used with a tiller fitted with either hoes or the cast-iron wheels AMR 031 available as an accessory. The additional weights AZG 030 (17 kg) available as an accessory can also be installed. STIHL recommends operating the ridger in combination with cast-iron wheels. Further information is available from your STIHL specialist dealer, on the Internet (www.stihl.com) or in the STIHL catalogue.

Cast-iron wheels:
Installing cast-iron wheels improves the traction of the tiller and therefore significantly increases the tensile force at the ridger. This improves the ridger function.

Additional weights:
An even better result can be achieved with additional weights. They improve the traction even further by increasing the overall weight of the tiller.

Assembly and disassembly

Risk of injury!
Always wear gloves when working on the ridger.Always work in pairs when installing or removing ridgers. Installation and removal are performed in the same manner for both ridgers. The pictures show the adjustable ridger AHK 701.

• Stop the engine and allow it to cool down.
• Park the tiller on level and solid ground.
