G010014

The other threaded holes on the product are intended for handling single parts only. You must not lift the entire assembly by using these threaded holes. For handling the parts, see product workshop documentation for suitable lifting methods and lifting adapters.

LIFTING EYE SCREWS

If lifting eye screws are used, lifting eye screws must be completely tightened. The lifting eye can be loaded only if the screw is properly tightened to the frame.

Failure to properly tighten the screw before allowing load pressure on the lifting eye may cause lifting eye to break and free fall of the product.

If you use mechanical tools for tightening, make sure not to overstrain the shank. Before lifting, make sure that the rope and/or hook is stretched.

When two lifting points are used, the lifting capacity depends on the angle of the lifting chains. The angle should not be less than 45°, as shown in the illustration. When the lifting eye screws are tightened, both rings should be aligned.

The loading capacity calculation applies to temperatures between -10 °C (14 °F) and 40 °C (104 °F).

Before reuse of lifting eye screws, make sure there are no surface flaws (for example pits, voids, folds and seams, deformation of the ring, missing or broken threads, rust, etc.).

The local, national safety standards for machines and lifting-tackles must always be strictly observed.

Note: The lifting eye must always be removed from the product and replaced with a screw before operation.

Lifting devices must safely carry the working weight of the product. See “Product specifications” on page 64.

DUST HAZARD

Breathing dust will cause death or severe injury.

Always wear approved respirator.

DANGER

169410_ENG-1

Airborne pollutants are microscopic particles, which will damage your health when inhaled. Aiborne pollutants on construction sites can be for example silica dust, oil fumes or diesel exhaust particles, visible or invisible. Especially in demolition sites, there may be other dangerous substances, such as asbestos, lead paints or other chemical substances.

The effect of airborne pollutants may be immediate if the substance is poisonous. The main danger with airborne pollutants comes from long term exposure, where particles are inhaled but not removed from the lungs. The disease is called silicosis, asbestosis or other, and will result in death or serious injury.

To protect yourself from airborne pollutants, always keep excavator doors and windows closed during operation. Excavators with pressurized cabins should be utilized in product operation. Proper maintenance of fresh air filters of the excavator is essential. Where pressurized cabins are not available, proper respirators must be utilized.

Stop working when bystanders are in the area of airborne pollutants and make sure they have proper respirators. Respirators are as important for bystanders as hard hats.Respirators for both operator and bystanders must be approved by the respirator manufacturer for the application in question. It is essential that the respirators protect from the tiny dust particles which cause silicosis and which may cause other serious lung diseases. Do not use the product until you are sure the respirators are working properly. This means each respirator must be checked to make sure that it is clean, that its filter has been changed, and to otherwise make sure the respirator will protect in the way it is meant to.

Always make sure dust has been cleaned off your boots and clothes when you leave your shift. The smallest particles of dust are the most harmful. They may be so fine that you cannot see them. Remember, you MUST protect yourself and bystanders from the danger of breathing or inhaling dust.

Always follow local laws and regulations for airborne pollutants in the working environment.

5. OPERATION

5.1 OPERATING INSTRUCTIONS

RECOMMENDED USE

The pulverizer is designed for use in demolishing work to pulverize demolition material. It can be used in recycling plants for separating the concrete from the reinforcement bars or for removing and regrinding road surfaces. For more information, contact your local dealer.

OPERATING CONDITIONS

Principles of installation

OperationRPV14R, RPV22R, RPV29R, RPV39R, RPV53R, RPV75R

Almost all carriers meeting mechanical and hydraulic requirements can be used to operate products. See “Product specifications” on page 64. The product is installed on the carrier much in the same manner as installing a bucket or other attachment. A flange-mounted products requires also a separate mounting bracket.

The products is connected to a carrier's hydraulic circuit with an installation kit. If the carrier is already fitted with an installation kit, the installation requires only suitable hoses and fittings. For product installation, secondary relief valves in the bucket cylinder circuit and the carrier auxiliary circuit are needed. If the carrier does not have a suitable kit to run attachments, one must be built. This may require a more complex installation, including new piping and additional valves such as a flow control valve or pressure relief valve.

Suitable kits can be ordered from the manufacturer or their local dealers, carrier manufacturers and their dealers, or third party suppliers.

Note: In models equipped with a system to prevent rotation of the product, remember to unlock the system before starting operation. See “Mounting and dismounting the product” on page 32.

Hydraulic oil

In general, the hydraulic oil originally intended for the carrier can be used with this product.

Operating temperature

The operating temperature is -20 °C (-4 °F) to 80 °C (176 °F). If you must work in a temperature lower than -20 °C (-4 °F), the product must be preheated before any operation can begin. Start the operation with low hydraulic flow.

Note: The temperature of the hydraulic oil must be monitored. Ensure that oil grade and monitored oil temperature together guarantee correct oil viscosity.

Operation RPV14R, RPV22R, RPV29R, RPV39R, RPV53R, RPV75R

PRINCIPLES OF OPERATION

The operation of the product is based on a static force produced by the hydraulic cylinder of the product. To increase the product's working life, pay particular attention to correct working methods.

Crushing is performed at the front of the jaws. NOTICE! Avoid using cutting blades for crushing. Doing so may damage the blades.

Cutting is performed with cutting blades at the rear of the jaws. The cutting blades can be reversed.

JAWS, TEETH AND CUTTING BLADES

Jaws

The jaws are operated by the hydraulic cylinder. One jaw is fixed and the other, equipped with breaking teeth, is moving. Crushing is performed using the crushing teeth of the jaws.

Crushing teeth

Crushing is performed using the crushing teeth of the jaws. The long-lasting, convex teeth are made of special steel. They are fastened with screws and can be replaced.

Crushing plate

The teeth of the crushing plate are made of special steel. The teeth are welded directly onto the plate. The crushing plate is removable, so that the teeth can be serviced separately.

Cutting blades

The cutting blades are fastened with screws. You can turn them to use unused cutting edges or replace them with new cutting blades. See “Turning and changing cutting blades” on page 49.

2. CARRIER HYDRAULIC OIL

2.1 REQUIREMENTS FOR HYDRAULIC OIL

GENERAL REQUIREMENTS

In general, the hydraulic oil originally intended for the carrier can be used with this product. However, since working with the product heats the oil more than with the usual excavation work, the temperature of the oil must be monitored.

If the temperature of the hydraulic oil exceeds 80 °C (176 °F), an auxiliary oil cooler is needed. The oil viscosity must be between 1000-20 cSt while the product is being used.

When the product is used continuously, the temperature of the hydraulic oil normalizes at a certain level depending on conditions and on the carrier. The temperature in the tank must not exceed the maximum allowed.

The product must not be started if the ambient temperature is below freezing and the oil is very thick. The machine must be moved to bring the oil temperature above 0 °C (32 °F) before working can start (viscosity 1000 cSt or 131 °E).

Carrier hydraulic oilRPV14R, RPV22R, RPV29R, RPV39R, RPV53R, RPV75R

OIL SPECIFICATIONS

The table below shows hydraulic oils recommended for product use. The most suitable oil is selected in such a way that the temperature of the hydraulic oil in continuous use is in the ideal area on the chart and the hydraulic system is used to best advantage.

Problems due to incorrect hydraulic oil viscosity in the product:

Oil too thick

■ Difficult start up

■ Stiff operation

■ Danger of cavitation

■ Sticky valves

■ Filter bypass opens, impurities in the oil are not removed

Oil too thin

■ Efficiency losses (internal leaks)

■ Damage to gaskets and seals, leaks

■ Accelerated wearing of parts, because of decreased lubrication efficiency

■ Danger of cavitation

Carrier hydraulic oil RPV14R, RPV22R, RPV29R, RPV39R, RPV53R, RPV75R

Note: We strongly recommend the use of different hydraulic oils in the summer and in the winter if there is an average temperature difference of more than 35 °C (95 °F). The correct hydraulic oil viscosity is thus ensured.

SPECIAL OILS

In some cases, special oils (for example biological oils and nonflammable oils) can be used with the product Observe the following aspects when considering the use of special oils:

■ The viscosity range in the special oil must be in the given range (1000-20 cSt).

■ The lubrication properties must be sufficient.

■ The corrosion resistance properties must be good enough.

Note: Although a special oil could be used in the carrier, always check its suitability with the product Contact the oil manufacturer or your local dealer for more information about special oils.

2.2 OIL COOLER

The carrier hydraulic system must be able to maintain a temperature within an acceptable level during the product operation. This is because:

1. Seals, wipers, membranes and other parts manufactured from the corresponding

materials can normally stand temperatures up to 80 °C (176 °F).

2. The higher the temperature is, the less viscous the oil gets, thus losing its

capability to lubricate.

A standard carrier, with a proper product circuit, meets the requirements of the necessary cooling capacity. If the oil temperature tends to be too high during product operation, the following must be checked:

■ The product circuit pressure relief valve should not be opened unnecessarily.

■ The product circuit pressure drops must be reasonable; that is, less than 20 bar

(290 psi) in the hydraulic line.

■ There should be no internal leakages in product or carrier hydraulic pumps, valves, cylinders, motors, etc.

If all of the above-mentioned items are in order, and the temperature of the hydraulic oil still tends to be too high, extra cooling capacity is needed. Contact the carrier manufacturer or your local dealer for details.

Carrier hydraulic oilRPV14R, RPV22R, RPV29R, RPV39R, RPV53R, RPV75R

2.3 OIL FILTER

The purpose of the oil filter is to remove impurities from the hydraulic oil. Air and water are also impurities in oil. Not all impurities can be seen with the naked eye.

Impurities enter the hydraulic system:

■ During hydraulic oil changes and refilling.

■ When components are repaired or serviced.

■ When the product is being installed on the carrier.

■ Because of component wear.

Normally the existing, main oil filters of the carrier are used as attachment circuit return line filters. Contact the carrier manufacturer or your local dealer concerning instructions for the filter change intervals.

In product work, the carrier oil filter must fulfill the following specifications:

■ The oil filter must allow maximum particle size of 25 microns (0.025 mm).

■ The oil filter material must be man-made fibre cloth or very fine gauge metallic

mesh to withstand pressure fluctuations.

■ The oil filter must have a nominal flow capacity of at least twice the product's maximum flow.

In general, oil companies guarantee new oils to have a maximum particle size of 40 microns. Therefore, filter the oil when filling the tank.

The damage caused by hydraulic oil impurities in the carrier and attachment circuits include:

Shortened working life of pumps and other components

■ Rapid wear of parts.

■ Cavitation.

■ Wear of cylinder and gaskets.

Reduced attachment efficiency

■ Accelerated wear of moving parts and seals.

■ Oil leakages.

Shortened working life and reduced lubricating capability of oil

■ Overheated oil.

■ Deteriorated oil quality.

■ Electrochemical changes in hydraulic oil.

Carrier hydraulic oil RPV14R, RPV22R, RPV29R, RPV39R, RPV53R, RPV75R

Malfunction of valves

■ Binding spools.

■ Rapid wear of parts.

■ Blocking of small holes.

Note: Component damage is only a symptom. The trouble itself will not be cured by removing the symptom. After any component damage due to impurities in the oil, the entire hydraulic system must be cleaned. Dismantle, clean and reassemble the product and change the hydraulic oil.

1. ROUTINE MAINTENANCE

1.1 OVERVIEW

This product is a precision-made hydraulic machine. Therefore, great care and cleanliness should be taken when handling any of the hydraulic components. Dirt is the worst enemy in hydraulic systems.

Handle the parts carefully and remember to cover any cleaned and dried parts with a clean, lint-free cloth. Do not use anything other than purpose-designed materials for cleaning hydraulic parts. Never use water, paint thinners or carbon tetrachloride.

Components, gaskets and seals in the hydraulic system should be oiled with clean hydraulic oil before assembly.

Remember to grease the product parts regularly, according to the instructions in this manual.

Prior to maintenance or inspection, operate all the control levers to their fully extended stroke. This will release pressure within the hydraulic piping and prevent unexpected movement of the jaw and loss of oil through the hydraulic lines.

Close the jaws during maintenance or inspection. If you must leave the jaws open, remember to block the jaws to prevent them from closing.
