6.2.1 Cleaning

Notes

z Take care to ensure that the cleaning solvents used will not damage the seals, gaskets and other machine components.

z Do not use any aggressive cleaning solvents.

z It is especially important to clean the noise suppression mats with neutral cleaning agents!

z Use only lint-free cleaning rags.

z Use only dry filtered compressed air of a maximum pressure of 2 bar.

z On completion of cleaning, perform a visual inspection and a functional check of the machine as specified in Section 4.3.

WARNING

z Electrical and electronic components such as generators, switch cabinets etc. must not come into direct contact with the water jet!

z Wet cleaning of these components is prohibited!

z When wet cleaning the machine, always make sure that the water does not come into contact with electrical or electronic components.

z There is a risk of damage to the electrics of the machine from penetrating water. This can result in uncontrolled working movements being suddenly performed.

6.2.2 Oils and Lubricants

Use only oils and lubricants that have been approved by BAUER/

SENNEBOGEN. For a list refer to Lubricants chart. For proper operation of the machine, ambient temperature may range between ca. - 20°C and ca. + 40°C. When job site temperatures are outside this range, consult the BAUER/SENNEBOGEN service department before placing the machine in service.

Oil analysis Sampling and analyzing the oil at regular intervals will help to avoid unnecessary costs. A number of tests are carried out to establish:

z Condition of the oil

z Amounts of the wear metals in the sample z Rates of component wear

Recommended for the hydraulic system.

Further information is available from the BAUER/SENNEBOGEN service department.

Biodegradable oils and lubricants

Use of these materials is mandatory in those cases where leakage of oils and lubricants on a mineral-oil basis would present a hazard to the environment. The use of environmentally friendly lubricants is a requirement in water and nature reserve areas in particular.

Use must only be made of synthetic ester based biological oil.

WARNING

Any conversion to bio-oils and biological lubricants is not permitted until after the BAUER/SENNEBOGEN service department has been

consulted and written approval has been obtained.

WARNING

Mixing oils, lubrication or operational materials of different types is not permitted!

Filling or mixing oils, lubricants or any other operational fluids (e.g.

hydraulic oil, transmission oil, motor oil, coolant, etc.) of different types can lead to chemical reaction damage to machine components. This damage can in turn result in severe damage to property and to personal injuries.

Use oils, lubricants and operational fluids that are approved by SENNEBOGEN only.

Only mix oils, lubricants and operational fluids that are of the same type or identical (same specifications) from one manufacturer!

6.2.3 Coolant for CATERPILLAR - Drive motors

The Caterpillar - Drive motors can be recognised by the

17 character PIN (Product Identification Number) and the ratings plate among other things. E.g.: *CAT 0789BG 6SL12345*

Note

The Caterpillar - drive motors are filled with coolant z Caterpillar CAT ELC^TM (Extended Life Coolant)

in the factory. Use this coolant only for the Caterpillar drive motors!

SENNEBOGEN will accept no responsibility and will provide no war-ranty or make any guarantees for the use of any other coolants.

Note

Observe the coolant label in the cooler area.

ATTENTION!

Observe the notes in the operating instructions of the motor manufac-turer as well as the special additional documentation on the Caterpillar CAT ELC^TM- Coolant. These are for the operational safety of the ma-chine.

Note

SENNEBOGEN recommends using the pre-mixed coolant by Caterpil-lar CAT ELC^TM, which is available in two different concentrations.

6.2.4 Coolant - General

WARNING

Mixing coolants and adding cooling system sealing agents or anti-freeze that contains sealing agents is not permitted.

By filling or mixing different types of cooling fluid or cooling agent addi-tives, gelling, etc. can occur in the coolant leading to the cooler being plugged (build-up) and because of the engine overheating or if the cool-ing system fails for example, this can damage the machine.

WARNING

Mixing of nitrite-based cooling agents with amine-based agents pro-duces health-hazardous nitrosamine.

Use the coolant indicated and described in chapter 3.3.1 and 3.3.2 depending on the motor that is installed. The antifreeze is sufficient to -37 °C (-34 °F).

Note

Observe the coolant label in the cooler area.

If the ambient temperature at the work-site is under this value

(-37 °C (-34 °F)), observe the operating instructions of the motor man-ufacturer or contact SENNEBOGEN - customer service before starting operation.

Note

If only a small amount (up to max. 5 l) is required to will the water-cool-ant circuit and no suitable coolwater-cool-ant is available, you can top up with clean water in the mean time.

We recommend that you test the concentration at the next possible time before freezing temperatures however. In some cases, you must refill with the respective coolant so that the required mixture is achieved again to prevent freezing.

The coolant is not only required to guarantee the protection against freezing, it also performs the very important task of protecting against corrosion. This also requires checking for the correct concentration and adding when necessary.

Water

Note

z Use clean, neutral, filtered, fairly soft fresh tap water. Sennebogen recommends distilled water as the best variant.

z Please note that Caterpillar specifies using distilled water!

z Do not use ditch water, industrial drain water, salt water, sea water or rain water.

z Always fill using a water-coolant mixture. Observe mixing ratios. Mix before filling!

Ensure that the water has the following characteristics:

Note

Observe the recommended mixing ratio (see manufacturer's specifica-tions). If the coolant concentration is too high, the cooling and anti-freeze behaviour will deteriorate.

ATTENTION

Observe the specifications of the coolant manufacturer.

WARNING

Never fill with coolant when the motor is overheated. This will cause damage to the motor. Allow the motor to cool first.

WARNING

Regarding possible danger to health or environmental dangers, ob-serve the instructions for using the coolant manufacturer as well.

Using other coolants If you should ever use a coolant other than that specified, the following must be considered or expresslyobserved.

SENNEBOGEN will accept no responsibility and will provide no war-ranty or make any guarantees for the use of any coolants other than those previously indicated.
