Safety Information
Personal safety measures • Brief the technician and the operator before beginning maintenance or repair work.
Appoint someone to supervise the activities.
• Always work in groups of two when diagnosing a machine problem requiring the engine
to be running. Both persons must be trained on 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 Maintenance section of this Operator’s
Manual.
• Always keep a safe distance from all rotating and moving parts, for example, fan
blades, V-belt drives, PTO shaft drives, fans, etc.
• Before starting work on the machine, always ensure safe blocking/support.
• Apply special care when working on the fuel system due to the increased danger of fire.
• Engine 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.
• 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.
Preparing for maintenance and repair
work • Prior to performing repair and maintenance work, always attach a warning label such
as “Repair work—do not start machine!” to the control elements as a precautionary
measure.
• Observe the startup and shutdown procedures set forth in this Operator’s Manual. This
applies to any work concerning the operation, conversion or adjustment of the machine
and its safety-oriented devices, or any work related to inspection and maintenance.
• Prior to performing assembly work on the machine, stabilize the area under repair and
use proper lifting and support devices to change parts weighing more than
9 kg (20 lbs.).
• Perform maintenance work ONLY if:
• the machine is positioned on firm and level ground
• secured against unintentional movement
• all hydraulically movable attachments and working equipment have been lowered to
the ground
• if the engine is stopped
• if the starting key has been removed
• the pressure accumulator is discharged
• Perform maintenance work beneath a raised machine, attachments or additional
equipment ONLY if a safe and secure support has been provided. The use of hydraulic
rams or jacks as the sole method of support does NOT sufficiently secure raised
machines or equipment/attachments!
Performing maintenance and repairs • Observe the adjustment, maintenance and inspection activities and intervals set forth in
this Operator’s Manual, including information on the replacement of parts and partial
equipment. These activities must be performed only by qualified personnel.
• Disconnect the negative battery terminal when working on the electrical system.
• Do not allow the machine to be serviced, repaired, or test-driven by unauthorized
personnel.
• If maintenance with the engine running cannot be avoided, lower the stabilizer blade
and raise the control lever base.
