GENERAL
• Generally, all maintenance and servicing
work may only be performed when the en-
gine is at a standstill.
• Only open the engine hood when the en-
gine is at a standstill.
• Keep away from moving, rotating or re-
volving parts; do not touch these (danger
of accidents).
• Only perform maintenance and servicing
work if the machine is parked on a level,
stable ground and if it is secured against
rolling away and buckling (danger of bruis-
ing).
• Perform maintenance and servicing work
below the lifted driver's stand only when
the lock is latched in. Engine bonnet al-
ways fully open (danger of life).
• After maintenance and servicing activities
that require the lifting of the driver's stand,
the driver's stand must be reattached/
screwed to the engine frames. This is the
only way to ensure the roll-over protection.
• Individual parts and bigger assemblies
must be attached carefully to lifting equip-
ment and safeguarded in a way that no
danger can emanate from these. Only use
appropriate and technically unobjection-
able lifting equipment as well as load-car-
rying equipment with sufficient loading ca-
pacity. Do not rest or work under suspend-
ed loads.
• Only order experienced persons with the
fixing of loads and the guidance of crane
operators. The guiding person must be in
visible range of the operator or have a
speaking contact to him or her.
• During installation work above body
height, use safe climbing aids and working
platforms intended for this purpose. Do not
use machine parts as climbing aids. In
case of maintenance work in greater
heights, wear fall protection. Keep all han-
dles, steps, handrails, pedestals, plat-
forms, ladders, free from dirt, snow and
ice.
• Clean all oil, fuel, and care agent residues
from the machine, in particular from con-
nections and screwed connections, prior
to maintenance and repair work (fire haz-
ard). Do not use aggressive cleaning
agents. Use fibre-free cleaning cloth.
• Prior to cleaning the machine with water,
vapour stream (pressure washer) or other
means of cleaning, cover/seal all aper-
tures which must not be penetrated by wa-
ter/steam/cleaning agent due to safety or
functionality reasons. Electric motors and
distribution cabinets are specially endan-
gered in this respect.
• After cleaning, the covers/seals must be
taken off completely.
• After cleaning, check all fuel lines, engine
oil lines, and hydraulic liquid lines for
leaks, loose connections, chafe marks,
and damage. Eliminate detected defects
immediately.
• Always tighten any screwed connections
loosened during maintenance and servic-
ing work.
• If the removal of safety devices is neces-
sary for rigging, maintenance and repair,
the safety devices have to be re-installed
and checked immediately after the end of
the maintenance and repair work.
• Take care for a safe and environment-
friendly disposal of operating and auxiliary
substances, replaced parts and contami-
nated cleaning material.
