MAINTENANCE 4.15 FIRE PREVENTION PRECAUTIONS See illustration Z 19360 In order to prevent risks of possible fire break out observe the fol- lowing items: 1. Keep the excavator clean, especially from inflammable mate- rials. Clean the excavator after servicing the hydraulic system, engine and fuel system by means of a steam jet. 2. Clean engine compartment, hydraulic pump compartment and service platform of the superstructure. Thereafter check fuel lines, engine oil lines and hydraulic oil lines for leakage, loose fastenings and damage. If any leakage, damage or loose fastening is found, corrective action must be taken immediately. 3.
Check all electrical cables, terminals and connections for loose fastenings, damage and wear. Replace or repair defective or worn parts without delay. 4. Check the turbocharger for correct mounting and tight exhaust, intake and lube oil connections. Carry out all necessary repairs without delay. 5. On machines equipped with a fire detection, actuation and suppression system: Refer to the manufacturers service manuals in part 3 of the Service Literature Binder for correct maintenance and inspec- tion of the systems. When checking the filling level of the dry chemical tanks, make sure that the extinguishing powder (Ansul FORAY dry chemical agent) is not compacted.
Stir up the extinguishing powder with a suitable stick until it is in a free flowing condition. NOTICE When cleaning the power house take care the heat detection sensors do not come in contact with hot steam or other hot agent. Otherwise the fire suppression system may be trig- gered. 6. Make sure fire extinguishers are charged and ready for use. NOTICE After cleaning lubricate all lubrication points by means of central lube system or manually. Lubricate swing circle gear after drying by means of the automatic lube system or manually. 467
