Supersedes SB G-000-61 Action for reducing risk of fire Warning! Please pay attention to the safety instructions in the Operator's and Service Manuals concerned. It frequently happens that construction machines work in environments where inflammable material collects on the machine. Machine fires can be caused by different reasons, such as:  Heating up through the exhaust system  Sparks in the electrical system To reduce the risk of fire, check the following points when carrying out maintenance work on the machine. General It is important that the machine is provided with suitable equipment to reduce the risk of inflammable material collecting on the machine in its working environment and then catching fire:  Guard over silencer  Protective screen for radiator to prevent collection and blockage by wood chips, sawdust and similar.  Cyclone pre-cleaner of turbo ll type to increase the cleaning capacity, particularly against coarse dust, sawdust, wood chips etc. This is self-emptying and is not connected to the ejector connection on the exhaust pipe. This connection is plugged, meaning that the spark extinguishing function of the silencer is still effective.  Keep the machine and equipment free from dirt, waste material, fuel and oil spillage. Instruct the machine owner to keep the machine clean at all times. Note If high-pressure washing is used for cleaning, take care not to damage the insulation on the electric cables, which can happen even at a relatively low water pressure and temperature. Engine Clean off all debris from the engine, particularly around the exhaust system, turbocharger and alternator.  Check that there is no fuel or oil leakage and that the hoses are clamped in such a way that no Language Code GB Product G Group 000 No. WLO 61 Version 2 Date 2005-10-09 Page Applies to models L220D , L330D , L150D , L180D , L50D , L70D , L90D , L120D , L30 , L50 , L50B , L50C , L50C OR , L70 , L70B , L70C , L90 , L90B , L90C , L90C OR , L120 , L120B , L120C , L150 , L150C , L160 , L180 , L180 HL , L180 CO , L180C , L180C HL , L180C CO , L320 , L330C , L330C LL , EL70 , EL70C , 6300 , 4200 , 4200B , 4300 , 4300B , 4400 , 4500 , 4600 , 4600B , L180D HL , L90D OR , L50C , L70C , L90C , L120C , L150C , L180C , L330C Page 1 of 3 7/4/2016 http://localhost:5011/prosis/40/OLD/GB/BLT/B00061GB.XML

chafing occurs.  Fuel filling. Take care when filling up with fuel that none is spilt outside the filling pipe. If fuel has run out when filling up, wipe it up immediately. Do not fill up with fuel near an open fire. Electrical system  If the machine is left unattended, always turn off the battery disconnection switch.  Check the electric cables for abrasion and that they are not subjected to wear. This particularly applies to unfused cables, which are red and marked R (B+). E.g., cables between:  Batteries  Battery and starter motor  Alternator and starter motor  Cable to engine starter element  Wire to engine stop solenoid  When fitting any extra equipment, make sure that all cables are fused and arranged and clamped in such a way that there is no risk of abrasion. Transmission  Clean off all debris.  Check that there is no oil leakage. Brake system (hydraulic)  Check that there is no oil leakage and that pipes and hoses are protected, undamaged and properly clamped. Protecting plates (bottom guard plates) On machines which are provided with bottom guard plates it is important that debris which has collected inside and on the plates is removed every day. The guard plates must be handled with care as they are very heavy. Instructions for correct handling of the plates can be found in the instruction book or supplement for the respective machine. Hydraulic system Check that there is no leakage. Welding Take great care when carrying out welding work on the machine. Make sure that fire extinguishing equipment is available. In cases where these cables have been disconnected it is important to make sure that they are fitted and clamped in such a way that there is no risk of abrasion. Unfused cables must not come into contact with oil or fuel hoses. Page 2 of 3 7/4/2016 http://localhost:5011/prosis/40/OLD/GB/BLT/B00061GB.XML
