Safety instructions
Personal safety measures
• 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 fire hazard.
• 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 – personal injury hazard.
• 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 – explosion hazard.

Operator's Manual and instructions for the respective assembly, release the pressure in
all system sections and pressure lines (hydraulic system) before performing any

• 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
• Observe the specific safety instructions in the work manual
