• 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 risk 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 on or with the machine,
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 on or with the machine 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 on or with the machine beneath a raised
machine, attachments or additional equipment ONLY if a safe and
secure support has been provided. The use of hydraulic hydraulic
cylinders 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.
