• Brief the technician and the operator before beginning special operations, repair work
and maintenance. Appoint a person to supervise the activities.
• Observe the specific safety instructions in the Maintenance section of this Operator's
Manual.
• Before taking up work on machine parts risky for life and limb (bruising, cutting), always
ensure safe blocking/support of these areas.
• Apply special care when working on the fuel system – increased risk of fire.
• Engine block and muffler system become very hot during operation and require cool-
down time after machine is shut off. Avoid contact with hot parts. Wait for the machine
to cool before touching components.
• Retainer pins can fly out or splinter when struck with force. Avoid striking the pins
during operation, repair or maintenance – risk of personal injury.
• Do not use starting fluid (for example, ether), especially in those cases in which a
heater plug (intake air pre-heating) is used at the same time – risk of explosions.

safety-oriented devices, or any work related to maintenance, inspection and repair,
observe the starting and stopping procedures set forth in the Operator's Manual, and
the information on maintenance.

roll away or start moving.
• If required, secure the maintenance area appropriately.In accordance with this
Operator's Manual and instructions for the respective assembly, release the pressure in
all system sections and pressure lines (hydraulic system) before performing any
maintenance.

• all hydraulically movable attachments and working equipment have been lowered to
the ground
• engine is stopped
• the starting key has been removed
• pressure accumulator is empty
• lock lever is folded up
• machine has been secured against unintentional movement
• Should maintenance or repair be inevitable with the engine running:
• Lower the stabilizer blade and lock the controls
• Only work in groups of two
• Both persons must be authorized for the operation of the machine
• One person must be seated on the seat and maintain visual contact with the other
person

label, such as "Repair work – do not start machine" to the starter lock or to the control
elements as a precautionary measure.
