• Do not cross slopes transversely; attachments and cargo must always be kept close to the ground, especially
when going downhill!
• Always adjust the driving speed to suit the conditions on downhill gradients! Never reduce speed on the
gradient, but always before the gradient.
• On downhill or uphill slopes, the load must be located on the uphill side.
• When leaving the wheel loader, always secure it against unintentional rolling and unauthorized use! Turn off
the engine, apply the handbrake, lower the attachments, remove the key and place the wheel chock in front of
the wheels!
2.3.2 Safety instructions for service mode
These safety instructions are with reference to special duties in the context of the use of the wheel loader and
maintenance activities – as well as troubleshooting during workflow or work relating to the disposal of ancillary
materials and operating resources.
• The adjustment, servicing and inspection tasks and deadlines specified in the operating instructions, including
information on replacing parts or components, must be observed.
• Adjustment, servicing and inspection tasks, as well as parts replacement, may only be carried out by qualified
personnel!
• The operating personnel must be informed before beginning special duties and maintenance works!
• When performing any work related to the operation, conversion or adjustment of the wheel loader and its
safety-related equipment, ensure that the switching on and off procedures are carried out in accordance with
the operating instructions!
• When carrying out any work relating to servicing, maintenance and repair, observe the operating instructions
for maintenance work and the specified deadlines!
• If the wheel loader is completely switched off during servicing and maintenance work, the following must be
observed (see 7. "SECURING THE WHEEL LOADER"):
- Secure the wheel loader against unexpected restarting by removing the ignition key!
- Attach a warning sign that the wheel loader is being worked on!
- Only carry out servicing and maintenance work when the wheel loader is parked on a level and solid
surface and secured against rolling away and jackknifing!
- If maintenance work can only be carried out with the attachments raised (= lifting frame), provide a
suitable safety support!
• Individual parts and larger assemblies must be carefully attached to lifting equipment and secured during
replacement. Only use suitable lifting gear in perfect technical condition and load handling equipment with
sufficient load capacity! Nobody may stand or work beneath suspended loads!
• Only experienced personnel may order loads to be lifted and instruct crane operators! The instructor must be
within sight of the operator or have voice contact with him!
• When working above head height, designated or other safety-oriented climbing aids and work platforms must
be used!
• Do not use machine parts as climbing assistance! Keep all handles, steps, railings, pedestals, platforms and
ladders free of dirt, snow and ice!
• The entire wheel loader, in particular connections and unions, must be cleaned of oil, fuel or maintenance
products at the beginning of the servicing and maintenance work! Use fiber-free cleaning cloths and no
aggressive cleaning agents!
• Before cleaning the wheel loader with water or steam jet (high-pressure cleaner) or other cleaning agents,
protect all openings into which no water, steam or cleaning agents may penetrate for safety and functional
reasons by covering/taping! Electrical components, the engine's combustion air inlet and outlet openings, and
tank openings are particularly vulnerable!
• Screw connections loosened during servicing and maintenance work, and especially oil or fuel lines, must be
tightened again prior to recommissioning! Check all lines and unions for tightness and good seating during
servicing and maintenance work.
