Instructions on fastening loads

• The help of an accompanying person is necessary for securing and detaching the load.

• The load must be secured so as to prevent it from falling or slipping.

• Fasten the lifting gear so that it is not possible to unhook the sling unintentionally.

• Position the lifting gear ensuring the sling is not deflected by other parts.

• Do not use any lifting gear and slings that are damaged or not sufficiently dimensioned.

• The lifting gear must be designed to withstand the load s tha t can arise in the different positions of the work equipment or parts of the boom. Lateral loads and diagonal tensile forces must also be taken into account.

Page 17

• The lifting gear must be checked regularly by a technician, at least

once a year.

• Replace damaged lifting gear immediately.

• Fasten lifting gear and slings avoiding danger (rotating parts, crushing

or shearing) for the person securing the load. Furthermore, neither must the work equipment be affected by the lifting gear, nor must the functions of the lifting gear be affected by external influences (e.g. dirt that cannot be removed by simple means).

• Do not place slings over sharp edges.

• Always wear protective gloves and a hard hat when working with lifting

gear and slings.

• The persons attaching or securing loads may approach the boom from

the side only, and only after the machine operator has given his permission. The machine operator may give his permission only after the machine is at a standstill and the work attachment no longer moves!

General instructions

• Staying under suspended loads, in the danger zone or under the

machine's attachment is prohibited.

• The machine operator and the person attaching or securing the load

must have visual contact.

• Persons guiding the load or securing it must stay in visual contact with

the machine operator! Should this not be possible, ask anoth er person to guide.

• The machine operator must guide the load the nearest possible to the

ground and avoid any oscillating or swinging movements!

• Perform machine travel with a raised load only if the path of the

machine is level!

• The machine operator must not raise loads over persons.

• The machine operator may not leave his seat as long as the load is

raised.

• Careful and prudent working is the best way to avoid accidents!Keep

the machine clean. This reduces fire hazard (such as from combustible materials like rags), and reduces the injury hazard or operational accidents that can be caused by dirt build-up on the travel pedals or foot rests and steps.

• Observe all safety, warning, and informational signs and labels on the

machine.

• Start and operate the machine from the seat only.

• The operator must sit in the seat, fasten and adjust the seat belt before

putting the machine into operation.

• Always adjust the seat position before starting work. Do not change the

seat position during machine travel or machine operation.

• Make sure that all safety devices are properly installed and functional

before starting work.

• Before putting the machine/attachment into oper ation (startup/moving),

make sure that no one in the immediate vicinity will be at risk.

• Perform starting and stopping procedures according to this Operator’s

Manual.

• Observe all indicator lights.

• Do not use starting fluid (for example, ether) especially in those cases

in which a heater plug (intake air pre-heating) is used at the same time.

• Make sure the control levers, the signaling and the light systems are

functional before operating the machine, and also before restarting after an interruption of work.

• Fold up the control lever base before releasing the seat belt in order to

avoid unintentional operation.

Work area awareness

• Familiarize yourself with the surroundings and circumstances of the

work site before beginning work. Be aware of:

- obstacles in the working and traveling area

- the soil bearing capacity

- any necessary barriers separating the work site from public roads

• Always keep at a safe distance from the edges of building pits and

slopes.

• Look out for the following when working in buildings or in enclosed

areas:

- height of the ceiling/clearances

- width of entrances

- maximum load of ceilings and floors

- sufficient room ventilation — carbon monoxide poisoning hazard.

• Observe the danger zone. See “Danger zone awareness”.

• Use the rearview mirror to stay aware of work area obstacles and

personnel.

• Always switch on the work lights in conditions of poor visibility and after

dark. However, make sure that users of public roads will not be temporarily blinded by the work lights.

• Provide additional lighting of the work area if the lights of the machine

are not sufficient for performing work safely.

Danger zone awareness

Operating the machine

• The danger zone is the area in which persons are in danger du e to the movements of the machine, work equipment, additional equipment, or material.

• The danger zone also includes the area affected by falling material, equipment or construction debris. The danger zone must be extended by 0.5 m (20 inches) in the immediate vicinity of buildings, scaffolds, or other elements of construction.

• Seal off the danger zone if it is not possible to keep a safe distance. Stop work immediately if persons do not leave the danger zone in spite of warnings!

• Never operate the machine if you are standing on the ground.

• Operate the machine ONLY when you are seated and you have fastened your seat belt. Stop the engine before releasing the seat belt.

• During operation on slopes, travel or work uphill or downhill. If traveling across a slope cannot be avoided, bear in mind the tilting limit of the machine. Always keep the attachments/work equipment close to the ground. This also applies to traveling downhill. When traveling or working across a slope, the load must be on the uphill side of the machine.

• On sloping terrain, adapt your travel speed to the prevailing ground conditions.

• Never get on or off during machine operation or tra vel, and do not jump off the machine.

• The travel control levers require practice before an operator becomes familiar with the control response. Therefore, adjust the travel speed to your abilities and the surroundings.

• When traveling across a slope with the telescopic undercarriage extended, position the boom facing down the slope, and the bucket about 10–20 cm (4–8’’) above the ground. This will help to minimize the possibility of personal injuries and equipment damage caused by a hydraulic hose/connector failure in the telescopic undercarriage actuation system. The weight of the machine will cause the undercarriage to retract to the narrow configuration if h ydraulic system pressure decreases due to lost fluid.

• Install a front guard when working in areas with a risk of objects falling from the front (e.g. demolition work).

• On sloping terrain always adapt your travel speed to the prevailing ground conditions! Never change to lower gear on a slope but always before reaching it!

Carrying passengers

• Do not transport people on the machine or in the attachment.

• Never install a man basket or a working platform to the machine.

Mechanical integrity

• Take the necessary precautions to make sure the machine is used only when in a safe and serviceable state.

• Operate the machine ONLY if all protective and safety-oriented devices (ROPS, removable safety devices, soundproofing elements, mufflers, etc.) are in place and fully functional.

2-8 OM ET18/20/24 us 1.3 * Sicherheit(us).fm

• Check the machine before entering the cab to operate the machine for

visible damage and defects. Report any changes, including chang es in the machine’s function and response, to your supervisor immediately!

• If the machine is functioning unpredictably, stop the machine immedi-

ately, lock it, and report the malfunction to a qualified tecnician or supervisor. Safety-relevant damage or malfunctions of the machine must be rectified immediately.

Traveling

• When traveling on or in public areas, observe all applicable regula-

tions. Make sure beforehand that the machine is in compliance with these regulations.

• Installed work lights must NOT be used for travel.

• When crossing underpasses, gates, bridges and tunnels, or when

passing under overhead lines, make sure the clearance height and width are sufficient to avoid contact.

• Empty the bucket before traveling on public roads.

2.7 Applications with Lifting Gear

Low-load operation

Stopping the engine

The running performance of the engine can be negatively affected if it runs at idling speed or high speed and at less than 20 % of the load.

► Run the engine in regular operation at loads of over 20 %.

Possible consequences of low-load operation are:

• Increased lube oil consumption.

• Lube oil in exhaust system, and therefore engine contamination.

• Blue smoke in exhaust gas.

Engine damage by stopping the engine after full load. ► In order to stabilize the temperature, let the engine run at

idling speed with no load for at least 5 minutes, and then switch it off.

Turn the starting key to “0” and remove it.

Fig. 117: Automatic engine speed setting

Automatic engine speed setting (option)

The switch is located on the right-hand switch panel. Diesel engine speed is automatically reduced to idling after 5 seconds if

no hydraulic functions are performe d and if the au tomatic engine speed setting is enabled.

As soon as a hydraulic function is performed with the control levers/travel levers, diesel engine speed is automatically increase d again to the engine

speed adjusted with the throttle.

Position Function

ON Press switch 43 down

OFF Press switch 43 up

5.3 Brakes

Hydraulic brake

Releasing the travel levers/travel pedals brakes the machine. When traveling downhill, the automatic hydra ulic brake valves pre vent the

machine from traveling faster than the admissible travel speed.

Automatic engine speed setting is enabled, the indicator light in switch 43 illuminates

Automatic engine speed setting is disabled, the indicator light in switch 43 goes out

Mechanical brake

Reduce travel speed with the travel levers/travel pedals, an d not with the engine speed control of the diesel engine.

The stabilizer blade is used as a parking brake. Press the stabilizer blade against the ground.

Information

Fig. 118: Travel position

20 to 30 cm

(8 – 12 in)

Travel position

Traveling and stopping

• Position the machine as shown.

• Position the boom at the center and raise it about 20 to 30 mm (8 – 12

in) off the ground.

During machine travel, raise the stabilizer blade sufficiently high off the ground to avoid ground contact on rough terrain.

Starting machine travel

After starting the engine:

• Indicator lights 29 (charge indicator light) and 30 (engine oil pressure)

go out.

• Slowly actuate the travel lever. ➥ Machine moves off.

Stopping

The travel levers automatically return to their initial positions as soon as they are released. This creates sufficient hydraulic braking effe ct.

When traveling downhill, the automatic hydraulic brake valves prevent the machine from traveling faster than the admissible travel speed.

Operating temperature range

The following operating conditions must be fulfilled in order to ensure optimal output and a long service life of the machine.

Do not operate the machine at ambient temperatures above +45 °C (+104 °F) or below −15 °C (−5 °F).

The machine will not start machine travel unless the control lever bases are folded down.

Use the travel levers to reduce the travel speed as required.

WARNING

Traveling on slopes

Accident hazard due to tipping over or slipping of the machine on slopes!

Can result in severe injury or death.

► Travel on slopes only on firm and level ground. ► Travel on slopes only with the telescopic travel gear ex tended

(normal operation).

► Never exceed the stability limits of the machine (maximum

gradient angle 15°, maximum lateral angle of inclination 10°).

► Raise the boom 20 – 30 cm (8 – 12 in) off the ground and

position it straight ahead at the center of the machine. In an emergency, lower the boom immediately to increase stability.

► Do not actuate high speed when traveling uphill or downhill. ► Do not travel downhill in reverse travel speed. ► Do not turn or swivel the upper carriage and the boom when

traveling downhill or uphill with a full attachment.

► Traveling diagonally on slopes is prohibited.

Stones and the humidity in the upper layer of the ground can drastically affect machine traction and stability.

The machine can slip sideways on gravel or loose, rocky soil. The stability of the machine can be reduced on rough terrain.

Newly filled or muddy ground can give away under the weight of the machine, or the tracks can dig into the ground and increase the angle of the machine (maximum gradient angle and maximum lateral angle of inclination).

If the engine dies as you travel on a slope, immediately put the control levers to neutral position and start the engine again.

Observe under all circumstances when traveling uphill and downhill:

• Keep the travel levers near the neutral position.

• Perform slow and smooth travel movements.

• Avoid jerking the control levers.

• Reduce the engine speed.

The machine can slip even on gentle slopes if it travels across grass, leaves, humid metal surfaces, frozen ground or ice.
