SAFETY INSTRUCTIONS

General informationWorking with trucks, buses and the accompanying service products should not pose any problems if operators,maintenance personnel and repair staff receive suitable training.

The following sections include summaries of important regulations listed according to major topics. Theintention is to provide the knowledge needed to avoid accidents which could lead to injury, damage andenvironmental pollution. They represent only a small excerpt from the wide range of accident preventionregulations and cannot replace these. It goes without saying that all other safety regulations must befollowed and that the corresponding action must be taken.

Additional direct references to danger are contained in the instructions at points where there is a potentialdanger.

Accidents may happen in spite of all precautionary measures having been taken. In such an eventuality,obtain immediate medical assistance from a doctor. This is particularly important if the accident involves skincontact with corrosive acid, fuel penetration under the skin, scalding by hot oil, antifreeze spraying into eyes,etc.

1. Regulations for preventing accidents leading to injury to personnel

– Secure units during their removal.– Support the frame when working on the pneumatic or spring suspension system.– Keep units, ladders, stairs, steps and the surrounding area free from oil and grease.Accidents caused by slipping can have very serious consequences.

Only authorised technical personnel are entitled to perform inspection,adjustment and repair work

Working on the brake system– Perform visual, function and effectiveness checks on the brake system after carryingout any work on it whatsoever. These checks must be made in accordance with thesafety inspection (SP).

– Check the function of ABS/ASR and EBS systems using a suitable test system (e.g.MAN-cats).

– Collect hydraulic oil and brake uid as it drains out.– Hydraulic oil/brake uid is poisonous!Do not allow brake uid to come into contact with food or open wounds.

– Treat hydraulic oil/brake uid as hazardous waste!Comply with the safety regulations for preventing environmental pollution.

Operating the engine– Only authorised personnel are permitted to start and operate an engine.– Do not approach moving parts of a running engine too closely.Do not wear baggy clothing and tie up or cover long hair.Ensure adequate ventilation if you are working in enclosed spaces.

– Do not touch units with your bare hands when they are at operating temperature.Danger of burns!Always wear protective gloves when changing oil (in units at operating temperature)in particular.

– Do not open the coolant circuit unless the engine is cool.

K100 2nd edition 15

INTRODUCTION

Suspended loads– No-one is allowed to stand under a unit suspended from a crane hook. - Keep alllifting tackle in good condition -

Working on high-pressure lines– Do not attempt to tighten or loosen pipe lines and hoses when they are underpressure (e.g. lubrication circuit, coolant circuit and hydraulic oil circuit).Fluid spraying out represents an injury hazard!

– Do not hold your hands under the jet of fuel when checking the injector nozzles. Donot inhale fuel vapours.

Working on the vehicle electrical system– Always disconnect the batteries before working on the electrical system.Disconnect the earth cable rst and connect it last when reconnecting.

– Measure voltage only using a suitable measurement device.The input resistance of the measurement device must be at least 10 MΩ.

– Tow-start the vehicle only with the batteries connected (minimum charge 40%)! Donot use a boost-charger to jump-start the vehicle! Always disconnect the positiveand negative leads before boost-charging batteries.

– Disconnect the batteries and recharge them every 4 weeks if the vehicle is not inuse.

– The ignition must be switched off before the wiring harness plugs of the electroniccontrol units are disconnected or connected up.

Important! Battery gases are explosive!– Oxyhydrogen gas may form in enclosed battery boxes. Take particular care afterlong journeys and after charging the batteries with a battery charger.

– When the batteries are disconnected this gas may be ignited by sparks producedby other continuously operating consumers, the tachograph etc. that cannot beshut down. Blow compressed air through the battery box before disconnecting thebatteries!

– Avoid short circuits caused by polarity reversal or by placing metal objects (spanners,mole grips, etc.) on the battery terminals.

Caution! Battery acid is poisonous and corrosive!– Wear appropriate protective clothing (gloves, protective apron) when handlingbatteries.Do not tilt batteries, acid may leak out.

16 K100 2nd edition

INTRODUCTION

Electric welding– Connect up the "ANTIZAP SERVICE MONITOR" protective device (MAN itemnumber 80.78010.0002) in accordance with the instructions supplied with the device.

– If this device is not available, disconnect the batteries and connect the positive cableto the negative cable in order to make a conductive connection.

– Always earth the welding equipment as close as possible to the welding area. Do notlay the cables to the welding equipment in parallel to electrical cables in the vehicle.

– The chassis is not intended for use as an earth return. If attachments are to betted to the vehicle (e.g. a taillift), additional earth (ground) lines with an adequatecross-section must be tted as well. Otherwise the earth connection may be createdalong wire cables, wiring harnesses, gearbox shafts, gears etc. Severe damagecould result.

Painting– If paint spraying is to be carried out, do not expose the electronic components tohigh temperatures (max. 95 °C) for more than brief periods; a time of up to 2 hoursis permissible at a maximum of 85 °C. Disconnect the batteries.

Working on plastic tubes - Danger of damage and re!– The warning sign opposite is attached to the inside of the diesel fuel or heating oiltank ap. It warns you against welding or drilling near to plastic tubes.

Working with the cab tilted– Keep the tilting area in front of the cab clear.– Keep out of the area between the cab and the chassis during the tilting process. Thisis a danger area!

– Always tilt the cab past the tilting point to its nal position.

Working on the air-conditioning system– Refrigerant uids and vapours represent a health hazard, avoid contact with themand protect your eyes and hands.

– Do not drain gaseous refrigerants in enclosed rooms.– Do not mix CFC-free refrigerant R 134a with R 12 (CFC) refrigerant.

2. Notes on preventing damage and premature wear on units– Only subject units to the load which they have been designed to cope with in accordance with theirdesignated use. Do not overload them.

– If a fault occurs during operation, determine its cause immediately and correct the problem before the faultcan get any worse.

– Clean the units thoroughly before repairs. Ensure that no dirt, sand or foreign objects can get into the unitswhilst carrying out repairs.

– Always use genuine parts. Fitting “equivalent parts” made by other companies can lead to severe damage,and the workshop that did the work will be responsible for it. See the section entitled "Limited liability foraccessories and parts".

– Never run a unit dry, in other words always make sure that it has been lled with oil before running it.– Never run engines without coolant.– Apply a suitable information sign to units that are not ready to be operated.

K100 2nd edition 17

INTRODUCTION

– Only use service products (engine and gearbox oil as well as antifreeze and anti-corrosion protection) thathave been approved by MAN. Keep your workplace clean.

– Comply with the specied maintenance intervals.– Do not ll engine/gear oil above themaximum level mark. Do not exceed themaximumpermitted operationaltilt.

– Severe damage to the unit could result from failure to follow these regulations.

3. Limited liability for accessories and partsIn your own interests, you are recommended to use only accessories expressly approved by MAN andgenuine MAN parts. The reliability, safety and suitability of these parts and accessories have been determinedspecically for MAN vehicles. Despite constant market observation, we cannot judge the aspects of otherproducts, nor can we accept responsibility for them – even if they have been ofcially approved by the GermanTÜV technical inspection authorities or some other ofcial body.

Attachments and special bodiesComply with the safety instructions and regulations issued by the body builder in question if attachments orspecial bodies have been tted. Always follow the instructions in the appropriate MAN Guide to Fitting Bodies(www.manted.de). Written approval/release/conrmation from department TDB is required if the appropriateMAN Guide to Fitting Bodies is not complied with.

Taking out of operation and storingThe special measures described in MAN Works Standard M 3069 Part 3 apply if buses or trucks are to bewithdrawn from service or stored for a period longer than 3 months.

4. Handling brake pads and similar components– Harmful dust may be released when brake pads are machined, in particular during skimming and grindingas well as when wheel brakes are blown out.

– Please take the necessary precautionary measures and observe the following safety advice to avoidpossible damage to your health:

– If possible, carry out the work in question in the open or in an area equipped with an efcient ventilationsystem.

– If possible, use hand-operated or slow-running tools, equipped with a dust-collector if required.– Fast-running tools should always be tted with such devices.– If possible, wet the workpiece prior to cutting or drilling.– Dispose of brake pads or linings as hazardous waste in an environmentally sound manner.

5. Regulations for avoiding injury and environmental contamination

CoolantTreat undiluted antifreeze as hazardous waste. Follow the instructions issued by the relevant local authoritywhen disposing of used coolant (mixture of antifreeze and water).

Cleaning the cooling circuitDo not pour cleaning uids and rinsing water down the drain if this practice is restricted by specic localregulations. However, the cleaning uid and rinsing water must in all cases have been passed through an oiltrap with a sludge trap.

Cleaning the lter insertWhen blowing compressed air through the lter insert, make sure the lter dust is collected by a vacuumor is blown into a dust collection bag. Otherwise, use a respiratory protection mask. Wear rubber glovesor use a skin barrier hand cream when washing out the insert, because cleaning agents have aggressivegrease-dissolving characteristics.

Engine/gear oil, lter cartridges, elements and box-type lters, desiccant cartridgesOnly dispose of used oil at an approved collection point or depot. It is extremely important that oil is notpoured down the drain or onto the ground since it can pollute drinking water! Filter inserts, cartridges andbox-type lters (oil and fuel lters, desiccant cartridges for the air dryer) are classied as hazardous wastematerials and must be disposed of properly. Please follow the instructions of your relevant local authority.

Used engine/gear oilLengthy or repeated skin contact with any type of engine/gear oil removes grease from the skin. This cancause dry skin, irritation or skin inammation. In addition to these hazards, used engine oil contains dangerousmaterials which can cause skin cancer.

18 K100 2nd edition

INTRODUCTION

6. Health protection precautions– Avoid lengthy, excessive or repeated skin contact with used oils.– Protect your skin using a suitable skin protection agent or protective gloves.– Clean areas of skin which have come into contact with engine oil.– Wash the areas thoroughly with soap and water.– A nail brush enables more effective cleaning.– Special cleaning agents make it easier to clean dirty hands.– Do not use petrol, diesel oil, gas oil, thinners or solvents.– Apply a greasy skin cream after cleaning your skin.– Change out of clothing or shoes which have become soaked with oil.– Never put oil-soaked rags into your clothing pockets.Take care to dispose of used engine/gear oil properly.

- Oils can damage groundwater quality -

Therefore, never pour used oil onto the ground, into water or down the drains or sewers. Failure to complywith these instructions can lead to prosecution.

Collect and dispose of used oil carefully. Contact the point of sale, supplier or your local authority forinformation about collection depots.
