• Know where fire extinguishers are located and how to use them.
• Keep a first aid kit and an eye wash kit near the work area.
Keep emergency numbers for doctors, ambulance service, hospital, and fire department near your telephone.
Handle fluids safely-avoid fires
Figure 4 Avoid fires
• HandIe fuel with care. It is highly flammable.
Do not refuel the machine while smoking or when near open flame or sparks. Always stop the engine before refuelling machine. Fill the fuel tank outdoors.
Store flammable fluids away from fire hazards. Do not incinerate or puncture pressurized containers.
Dispose of fluids properly
5
Do not pour oil into the ground
Improperly disposing of fluids can harm the environment and ecology. Before draining any fluids, find out the proper way to dispose of waste from your local environmental agency.
Catch draining fuel, oil, or other fluids in suitable containers.
Do not use food or beverage containers that may mislead someone into drinking from them. Wipe up spills at once.
Do not pour oil into the ground, down a drain, or into a stream, pond, or lake.
Observe relevant environmental protection regulations when disposing of oil, fuel, coolant, filters, batteries, and other harmful waste.
Working in contaminated environment
Figure 6
Avoid breathing dust
Used cab and engine air filters from machines which operate in environments containing asbestos or other dangerous dust must be placed in the tight-fitting bag, before they are deposited in a designated place.
The machine must be equipped for work within an environment which is contaminated or constitutes a health hazard before the work is initiated. Besides, special local regulations apply for such operations and for servicing a machine which has been used in such environment.
Crystalline silica (quartz) dust
Because crystalline silica is a basis component of sand and granite, many activities at construction sites produce dust containing crystalline silica. Trenching, sawing and boring of material containing crystalline silica can produce dust containing crystalline silica.
If dust which contains crystalline silica is present there are guidelines which should be followed.
1. Be aware of the health effects of crystalline silica and that smoking adds to the damage.
2. Be aware of and follows OSHA (or other) guidelines for exposure to airborne crystalline silica.
3. Know the work operations where exposure to crystalline silica may occur.
4. Participate in air monitoring or training programs offered by the employer.
5. Be aware of and use optional equipment controls such as water sprays, local exhaust ventilation, and enclosed cabs with positive pressure air conditioning.
6. Where respirators are required, wear a respirator approved for protection against crystalline silicacontaining dust. Do not alter the respirator in any way. Workers who use tight-fitting respirators cannot have beards/mustaches which interfere with the respirator seal to the face.
7. If possible, change into disposable or washable work clothes at the work site ; shower and change into clean clothing before leaving the work site.
8. Do not eat, drink use tobacco products, or apply cosmetics in areas where there is dust containing crystalline silica.
9. Store food, drink and personal belongings away from the work area.
10. Wash hands and face before eating, drinking, smoking, or applying cosmetics after leaving the exposure area.

Electric welding
Before electric welding is carried out on the machine or any attachment installed to the machine, the current must be turned OFF at the battery master switch.
Figure 5
When working on the battery, pay attention
Before carrying out any electric welding on the machine, the battery cables should be disconnected and the connectors pulled out of the electronic control units.
When disconnecting and reconnecting, the leads should be without current (the battery master switch turned off).
• Connect the earth (ground) lead of the welding equipment as close to the welding point as possible.
Before welding, remove all paint from an area of at least 10 cm (4 inch) around the point of welding. Paint which is heated gives off unhealthy gases.
All paint decomposes when heated and forms a great number of compounds, which may cause irritation and be dangerous to ones health after repeated or prolonged exposure.
In addition to the health hazard, the weld will be of inferior quality and strength, which, in the future, may cause the weld to break. Therefore, never weld directly on a painted surface.
• When working on the battery, wear goggles or safety glasses.
Sulfuric acid in battery electrolyte is poisonous.
It is strong enough to burn skin and eat holes in clothing and cause blindness if splashed into the eyes. If you spill acid on your clothes or skin, immediately flush with large quantities of clean water, then get medical attention.
• If splashed into the eyes, flush with water and get medical attention immediately.
• Keep sparks, lighted matches, and open flame away from the top of battery. Battery (hydrogen) gas can explode.
Figure 6
Battery posts and cables can burn you
• Battery posts and cables touched by metal objects can short circuit and burn you.
• Keep tools away from posts, wires and terminals.
• Tighten the battery terminals to ensure good contact.
When disassembling and assembling the battery, make sure that the battery terminals are correctly connected.

Do not use water or steam in the cab
If water gets to the electrical system, abnormal operation or failure can result. Do not use water or steam on sensors, connectors and instruments in the cab.
Cautions during operation
Figure 8
Be careful when opening the grease valve
When removing covers which are under internal pressure or under pressure from a spring, always leave two screws in position on opposite sides.
Slowly release the pressure, then slowly loosen the screws.
High pressure grease in the spring package of the undercarriage can explode and injure you.
Be careful when opening the grease valve.
Do not loosen the grease valve more than 1 turn until the pressure is released.
• When assembling or installing parts, always use the specified tightening torque.
When installing protective parts such as guards, or parts which rotate at high speed, be particularIy careful to check if they are installed correctly.
Figure 9
Do not contact rotating parts
• Be sure that your clothes or hair do not contact any rotating components

Safety when handling the waste handler
Follow the safety rules in the standard Operator's Manual for the respective machines before carrying out any operation, service and maintenance. For service work high up on the machine, always use footsteps and stepping surfaces intended for this purpose.
It is important that waste, which accumulated inside guard plates, covers and by cylinders, is removed daily in order to avoid fire hazards. Also make sure that waste, which has accumulated around the engine, is removed and check that there are no fuel NOTE or oil leaks. At the slightest sign of a leak remedial action must be taken immediately. When operating in an area which is contaminated or dangerous to one's health, the machine must be especially equipped for the exact purpose. Specific local safety regulations apply within such areas and also when servicing the machine.
High-pressure wash
If high-pressure wash is used for cleaning, make sure not to direct the water jet against electrical cables and electrical components. Even at reduced pressure and temperature the insulation on the cables may be damaged. Correct distance and constant movement of the nozzle will reduce the risk of damage.
Spring loaded items
If disassembly of the spring-loaded items is required, take caution to ensure that you are well protected from the load release which may be sudden and pose an impact related injury threat.
Hot fluids and parts
To avoid burns, be alert for hot parts on the assembly for a machine that has just been stopped and has fluids in lines, tubes and compartments. Be careful when removing fill plugs and other components on the fan assembly. Hold a rag over the plug to prevent being sprayed or splashed by liquids which may be under pressure. Always wear the appropriate protective equipment when dealing with hot fluids and parts.
Service and cleaning
Damage to the waste handler caused by the waste must be prevented, while at the same time all important functions and components must be accessible for service and maintenance. Therefore, the machine is equipped with a fan, guard plates and access covers in order to facilitate cleaning and service work as well as a fan.
In case of fire in the machine with fire suppression system
Extinguishing of flowing flammable liquid fires may result in a reflash unless all NOTE sources of ignition have been removed. Flammable gases present a potential explosion hazard if the flow of gas is not stopped before or during extinguishm ent.
Discharge of a fire suppression system is noisy and can produce a large cloud of NOTE extinguishing agent ternporarily obstructing vision. Breathing the extinguishing agent is unpleasant and may cause some irritation.
NOTE
Don't restart the machine until it has been serviced and cleaned. Use a water stream or compressed air to remove dry chemical residue immediately to avoid corrosion. For further information about fire prevention measures, see the standard Operator's Manual.
