Action for reducing risk of fire
WARNING
Please pay attention to the safety instructions in the Operator's and Service Manuals concerned.
Regarding: General
It frequently happens that construction machines work in environments where inflammable material collects on the machines. Machine fires can be caused by different reasons, such as:
Heating up through the exhaust system
Sparking 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.
Examples of such equipment for Volvo BM wheel loaders are:
Guard over silencer.
Protective gauze for radiator to prevent collection and blockage by wood chips, sawdust and similar.
Cyclone pre-cleaner of turbo 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 silincer 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.
NOTICE
If high-pressure washing is used for cleaning, take care not to damage the insulation on the electric leads, which can happen even at a relatively low water pressure and temperature.
Engine
Clean off all rubbish 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 chafing occurs.
Fuel filling.
Take care when filling up with fuel that none is spilt outside the filling pipe.
Fuel mixed with dust and rubbish is a significant cause of fire.
If fuel has run out when filling up, wipe it up immediately. Do not fill upp with fuel near an open fire.
Electrical system
If the machines is left unattended, always turn off the battery disconnection switch.
Check the electric leads for abrasion and that they are not subjected to wear. This particularly applies to unfused leads, which are red and marked R (B+).
E. g., leads between:
Batteries
Battery and starter motor
Alternator and starter motor
Lead to engine starter element
In cases where these leads have been disconnected it is important to make sure that they are fittedand clamped in such a way that there is no risk of abrasion. Unfused leads must not come into contact with oil or fuel hoses.
When fitting any extra equipment, make sure that all leads are fused and arranged and clamped in such a way that there is no risk of abrasion.

Clean off all rubbish.
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 such as compactors which are provided with bottom guard plates it is important that rubbish which has collectedinside 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 threre is no leakage.
Welding
Take great care when carrying out welding work on the machine. Make sure that fire extinguishing equipment is available. Take particular care when welding close to fuel and oil lines and tanks.
If fire breaks out
At the slightest sign of fire, and if the situations permits, take the following action:
Drive the machine away from the hazardous area
Let down the lifting arms, dumper body etc to bottom position
Stop the engine with the stop control and turn the key switch to "O"-position
Get out of the cab
Turn off the main current with the battery disconnection switch
Start fire extinguishing work and alert the fire service if necessary
In connection with delivery instructions or at other service visits, please inform the owner/driver of the contents of thisService Bulletin.
Action to be taken in case of abnormal lubricating oil consumption
WARNING
Please pay attention to the safety instructions in the Operator's and Service Manuals concerned.
Introduction
The oil consumption is in many cases used as a measure of the condition of the engine. Normally all engines use a certain amount of oil. The film of oil that lubricates the upper piston rings is combusted at the same time as the fuel, which gradually causesthe oil level to drop. There are of course also other factors that affects the oil consumption, e.g. operating conditions and the conditionof the engine. Here follows a short description of influencing factors, checking and measuring methods and which action can be takento manage any problems.
Factors influencing the oil consumption
Larger engines have as a rule a higher oil consumption than small engines. Oil has the ability to penetrate the smallest openings. Therefore, proceed as follows:
Check for oil leakage around the engine and components
Check for oil leakage at the turbocharger
Check for oil leakage at induction manifold / charge air pipe
Take a lubricating oil sample
All affected bolts should be check-tightened.
A too high oil level causes more oil to be thrown up on the cylinder walls and this increases the oil consumption. The oil level should be kept slightly below the full mark on the oil dipstick. Only check the oil level a few minutes after the engine has stoppedto allow the oil to run back to the sump, see Fig. 1.
Too thin oil will result in a higher oil consumption because of difficulties of maintaining a sealing film of oil between piston rings and cylinder wall at high temperatures. Too thick oil provides unsatisfactory lubrication and thereby increased wear, which in the long run will result in increased oil consumption. Always use the recommended oil grade and type according tothe Operator's Manual. Continuously high engine speed will result in warmer and thereby thinner oil. Increased oil consumption as described above. Frequent use of engine retarding causes increased oil consumption. Also long periods of idling / operating at low speed may cause increased oil consumption.
Faulty and worn piston rings, oil scraper rings, ring grooves, pistons, cylinders, valve guides result in high oil consumption, as oil leaks into the combustion chamber.
Abnormally low oil consumption
Some attention should also be given to low oil consumption, because the low oil consumption may beillusory. Used up oil may have been compensated through condensation water, coolant or fuel dilution, thus keeping the level unchanged. Intermixed coolant gives the oil a greyish tint, whereas intermixed fuel does not show. These factors result in impaired lubrication and should lead to more frequent oil changes. Intermixed fuel also mean an additional safety risk as the flash point of the oil is lowered. Take samples of lubricating oil and have them analysed.
Figure1
Checking and estimating oil consumption
The duration of the check / test period should be at least 250 hours (suitably between two oil changes and filter replacements) in order to avoid jumping to conclusions and taking unnecessary action. On an engine that has reached working temperature, the oil dipstick can be read off three minutes after stop. If the engine has been started, but not reached working temperature, wait for at least five minutes.
Copy the enclosed report form and make a note of the hour recorder reading at the start of the testperiod.
Begin with full fuel tank and new oil filled to the upper marking on oil the dipstick. Note the hour recorder reading and amounts every time you fill fuel, oil or coolant. Do not top up the oil until the level has reached the minimum line. Never fill oil to above the maximum line.
In case the oil is changed during the test period, check the oil level before draining and then fill to the same level. At the end of the test period, top up with oil to the maximum line and make a note of the amount.
Add up the noted information which then forms the base for calculating the oil consumption. The oil consumption is always stated as a relation between consumed oil and the amount of used fuel during the same period.
Example: An engine has during 250 hours used 18 litres of oil and 3000 litres of fuel. 18/3000 x 100 % = 0.6 %
Normal consumption
A new or fully overhauled engine often uses more oil than a run-in engine. Only after 1000–1500 operating hours, when the piston rings have bedded-in in the cylinders, is it possible correctly to determine the oil consumption.
Oil consumption of 0.3% or less = OK at full-load operation
Oil consumption of 0.3–0.75% = OK at light-load operation
If these limit values are exceeded, proceed as follows:
Carefully check the oil consumption (see instructions on the previous page) and contact the respective dealer regarding whether any action can be approved as a warranty job. A copy of the report form should be enclosed with the claim.
