• 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 and repair work beneath a raised machine, attachments or
additional equipment ONLY if a safe and secure support has been provided. The use of
hydraulic cylinders or jacks as the sole method of support does NOT sufficiently secure
raised machines or equipment/attachments.
• Before cleaning the machine with water, steam jet (high-pressure cleaner) or deter-
gents, cover or tape up all openings which – for safety and functional reasons – must
be protected against water, steam or detergent penetration. Special care must be taken
with the electrical system.
• Clean the machine, especially connections and threaded unions, of any traces of oil,
fuel or preservatives before performing maintenance/repair work. Do not use
aggressive detergents. Use lint-free cleaning rags.
• To avoid the risk of accidents, parts and large assemblies being moved for replacement
purposes must be carefully attached and secured to lifting gear. Use only suitable lifting
gear and suspension systems in a technically perfect state with adequate load-bearing
capacity.
Stay clear of suspended loads.
• Have loads fastened and crane operators instructed by experienced persons only. The
person giving the instructions to the operator must be within sight or sound of him.
• After cleaning, remove all covers and tapes applied for that purpose.
• After cleaning, examine all fuel, lubricant and hydraulic oil lines for leaks, chafe marks
and damage. Rectify all defects without delay.
• Observe the adjustment, maintenance and inspection activities and intervals set forth in
the Operator's Manual, including information on the replacement of parts/partial
equipment.
These activities may be performed only by a Wacker Neuson service center.
• Disconnect the negative terminal of the battery if work needs to be performed on the
electrical system.
• Do not allow the machine not be serviced, repaired or test-driven by unauthorized
personnel.
• Always use specially designed or otherwise safety-oriented ladders and working
platforms to perform overhead assembly work. NEVER use machine parts or attach-
ments/superstructures as a climbing aid.
• Wear a safety harness when performing elevated maintenance. Keep all handles,
steps, handrails, platforms, landings and ladders free from dirt, snow and ice.
• Do not use the work equipment as lifting platforms for persons.
• Use only original fuses with the specified current rating.
• In case of electrical system malfunctions, stop the machine immediately, disconnect the
battery (for example, by using the battery master switch), and perform troubleshooting
procedures.
• Work on the electrical system may only be performed by a technician with appropriate
training, in accordance with the applicable electrical engineering codes.
• Inspect and check the electric equipment of the machine at regular intervals. Defects
such as loose connections or scorched cables must be repaired immediately.
