____________________________________________Storage and transport

Storage and transport This chapter contains important information on the correct storage and transport of the machine. Observance of the instructions and tips will increase the service life and availability of the machine. You will also be able to carry out the transport work quicker and more safely. Careful attention to the points in this chapter will help you to simplify your day-to-day work.

Storage corrosion protection

Components coated with temporary corrosion inhibitor are protected for approximately six months.

Before delivery, the hydraulically operated equipment is operated and all axles, gear boxes, hydraulic oil tank, etc. are filled to their maximum fill point.

Storage of the machine and spare parts no direct exposure to sunlight

dirt and moisture

Store the equipment indoors or cover with a tarpaulin to protect against direct exposure to sunlight. Store the electrical equipment, electronic components, spare parts of rubber or plastic –such as seals and hoses –and hydraulic fluids only in closed rooms at temperatures of 60° F (15° C) to 77° F (25°C).

Protect the equipment and all spare parts stored outdoors against moisture and dirt, e.g. using tarpaulins.

The mounting surfaces of hydraulic components must be protected against corrosion and sealed with blind plates. Protect the hydraulic plug connectors and the connectors of the electrical cables with the caps and plugs supplied.

short-term storage

During short-term storage (approximately 4 weeks) of equipment outdoors, but at temperatures above freezing, electrical components need not be removed. Such components must be particularly protected against excessive temperatures, dirt and moisture.

long-term storage

If the equipment is to be stored more than six months, the hydraulic components must be completely filled with a corrosion inhibiting/frostproofing fluid such e.g. CV 50.

Fill the hollow areas of hydraulic components (e.g. the piston chambers) in horizontal position (ports facing upwards) until they start to overflow.

Then seal the ports with plastic or steel plugs.

The equipment must be stored in a well ventilated, dry room. Do not store outdoors.

______________________________________________________________ A6474X245 REV 8 3.3

BI016349

Storage and transport _____________________________________________ plastic deformation

random sample inspection

In order to prevent plastic deformation of the seal elements, cylinders must be stored in an upright position. Some cylinders must be removed so that they can be stored upright.

After a storage period of approximately two years, a random sample inspection must be performed to determine whether the measures taken and the method of storage has prevented damage.

natural aging

Even with proper storage, seals and hoses are subject to natural ageing. Do not use these parts if they have been stored for more than two years.

HFA fluids

Instructions on the storage of concentrates for hydraulic fluids can be found, if required, in chapter 6 in this operating manual.

IMPORTANT! Take care to insure that new supplies are stored separately from existing stock and that removal takes place on the “first in, first out”principle.

Transport Load units; dimensions and weights Observe the transport sheets for the machine and spare parts. They contain information on: ■

Dimensions

■

Weight

■

lifting points, etc.

Additional information on the dimensions and weights can be found in chapter 6 in this operating manual.

WARNING! Use only load handling devices complying with the technical and legal regulations for the transport of loads. You could be seriously injured or even killed by falling loads. Use only suitable load handling devices.

________________________________________________________________ 3.4 SU488 DM

BI016349

____________________________________________Storage and transport Before transport temperatures below freezing

Before transporting the equipment at temperatures below freezing, all hydraulic components operated with emulsion (HFAE or HFAS) must be completely drained and then filled with a corrosion inhibitor/frostproofing fluid (e.g. CV 50).

Transport of equipment at temperatures between -6° F (-21° C) and 40° F (-40° C) is only permissible when certain measures were taken to meet these conditions at the design and manufacture stages. Nevertheless, the individual parts and devices of this equipment must not be subjected to sudden impact loads at such low temperatures and may only be loaded statically or quasi-statically.

During transport of this equipment with floor-mounted vehicles at such low temperatures, measures must also be taken to ensure that the parts and devices are not subjected to sudden impact loads. At very low temperatures and on poor roads, the transport vehicle speed must therefore be limited to a maximum of 15 mph (25 kph) for truck transport.

electronic components

Electrical and electronic components must be removed for overseas transport or prolonged storage outdoors unless these components or the complete equipment is protected against harmful environmental influences by a suitable packaging.

The electrical cables remain in the equipment. They must be carefully protected against transport damage and soiling of the connections.

________________________________________________ Troubleshooting Troubleshooting procedures The following section lists possible problems encountered when servicing the machine and can aid in locating and correcting these problems.

This section covers basic hydraulic components, with each listed in a trouble-cause-remedy format.

For electrical instructions, troubleshooting, and maintenance procedures, refer to the “Dual Motor Controller Troubleshooting Guide”, part number A6474X226.

WARNING! Some procedures must be carried out with the cover of the electrical controller removed and some procedures require the controller to be energized during the tests. It is extremely important that you take all necessary precautions to prevent accidental electrical shock while working within the controller. An MSHA-certified electrician must supervise and inspect all work performed.

For maintenance procedures and tests that DO NOT require the controller to be energized, these precautions include:  Before removing the controller cover, remove power from the system by unplugging the battery.  When the cover is removed, wait one minute for the capacitors to discharge before working inside the controller. To insure that the capacitors are discharged, connect an insulated 100-ohm, 10-watt resistor between the center buss bar and the outer buss bar of the capacitor bank and hold for 30 seconds.  Use insulated gloves and tools where possible.  All connections must be tight and care must be taken to prevent bolts, nuts, washers and other small metal fasteners from being dropped or lost inside the controller. These lost fasteners could cause electrical shorts inside the controller.

For procedures that DO require that the controller be energized while the cover is off:  At no time should you reach inside the controller while it is energized. If it becomes necessary to make adjustments or to replace parts inside the controller, the machine circuit breaker must be turned to the “OFF”position and the capacitor bank discharged (see above). Once the circuit breaker is in the “OFF”position and the capacitor bank discharged, adjustments or parts replacements can be made.  Use insulated gloves and tools where possible.

_______________________________________________Permissible media Permissible media Lubrication fluids and greases NOTICE! Only use approved lubrication fluids and greases. These fluids and greases provide more reliable operation of the mechanical and hydraulic functions of the machine.

IMPORTANT! The lubrication fluids and greases listed in the same table can be mixed. Other products may only be used if the supplier can guarantee that they are equivalent.

Differently composed fluids and greases must not be mixed as this may change the consistency, i.e. the mixture can become thinner so that the lubrication effect is not sufficient. It may also be dangerous to use lubricating greases and fluids having the same specification base but different origins.

In case of doubt, the manufacturer of the lubrication to be used should be contacted as to the compatibility of the lubrication in question.

IMPORTANT! It is expressly pointed out that the approval of the listed products relates only to the pure technical use in our mechanical and hydraulic systems. The responsibility for the constituents used in the hydraulic concentrates lies solely with the respective manufacturer.

IMPORTANT! Be sure to use the manufacturer’s instructions for use.

NOTICE! When performing maintenance on the machine, all used oil and lubricants should be disposed of per your local EPA standards.
