INTRODUCTION

Safety rules - Ecology and the environment Soil, air, and water quality is important for all industries and life in general. When legislation does not yet rule the treatment of some of the substances that advanced technology requires, sound judgment should govern the use and disposal of products of a chemical and petrochemical nature.

Familiarize yourself with the relative legislation applicable to your country, and make sure that you understand this legislation. Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, anti-freeze, cleaning agents, etc., with regard to the effect of these substances on man and nature and how to safely store, use, and dispose of these substances.

Helpful hints • Avoid the use of cans or other inappropriate pressurized fuel delivery systems to fill tanks. Such delivery systems may cause considerable spillage.

• In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of these products contain substances that may be harmful to your health.

• Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.

• Avoid spillage when you drain fluids such as used engine coolant mixtures, engine oil, hydraulic fluid, brake fluid, etc. Do not mix drained brake fluids or fuels with lubricants. Store all drained fluids safely until you can dispose of the fluids in a proper way that complies with all local legislation and available resources.

• Do not allow coolant mixtures to get into the soil. Collect and dispose of coolant mixtures properly.

• The air-conditioning system contains gases that should not be released into the atmosphere. Consult an air-conditioning specialist or use a special extractor to recharge the system properly.

• Repair any leaks or defects in the engine cooling system or hydraulic system immediately.

• Do not increase the pressure in a pressurized circuit as this may lead to a component failure.

• Protect hoses during welding. Penetrating weld splatter may burn a hole or weaken hoses, allowing the loss of oils, coolant, etc.

INTRODUCTION

Basic instructions - Shop and assembly Shimming For each adjustment operation, select adjusting shims and measure the adjusting shims individually using a micrometer, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value shown on each shim.

Rotating shaft seals For correct rotating shaft seal installation, proceed as follows: 1. Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.

2. Thoroughly clean the shaft and check that the working surface on the shaft is not damaged.

3. Position the sealing lip facing the fluid.

NOTE: With hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that they will move the fluid towards the inner side of the seal.

4. Coat the sealing lip with a thin layer of lubricant (use oil rather than grease). Fill the gap between the sealing lip and the dust lip on double lip seals with grease.

5. Insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a hammer or mallet.

6. While you insert the seal, check that the seal is perpendicular to the seat. When the seal settles, make sure that the seal makes contact with the thrust element, if required.

7. To prevent damage to the seal lip on the shaft, position a protective guard during installation operations.

O-ring seals Lubricate the O-ring seals before you insert them in the seats. This will prevent the O-ring seals from overturning and twisting, which would jeopardize sealing efficiency.

Sealing compounds Apply a sealing compound on the mating surfaces when specified by the procedure. Before you apply the sealing compound, prepare the surfaces as directed by the product container.

Hammer - Depressurising WARNING: The hydraulic pressure inside the hammer must always be released before making any adjustments or repairs when the hammer is connected to the carrier.

There may also be pressurized oil trapped inside the hammer even if the hammer is disconnected from the carrier.

Release the hydraulic pressure according to the following instructions before opening any plugs or valve covers.

1. Stop the carrier engine.

2. Operate boom and hammer controls to release any pressure trapped inside hoses.

3. Wait at least 10 min for oil pressure to drop inside hammer.

WARNING: This procedure does not release the pressure from the pressure accumulators.

Read the instructions dealing with the accumulator before disassembling the hammer.

Hammer - Filling - Body parts Pre-filling of large hammers in workshop If the hydraulic oil flow in the initial stage of test running of large hammers after assembly is high, then it is in some cases possible that contact between piston and body parts may occur.

The contact may be avoided with a slow startup of the pump, for example 30 L/min to fill the hammer, before delivering full oil flow.

We also recommend very strongly, that you prefill the hammer / valve housing with hydraulic oil in the assembly stage as shown in the figures 1 (pre-filling) and 2 (full).

When pre-filling the hammer please consider the following issues: 1.

Use only clean, fresh and proper oil for hydraulic hammer use, according to specification, including instructions to filter for 25 µm.

2.

When special oils (biological etc.) are used on carrier, use the same oil in pre-filling and test run.

3.

The oil needs to be poured at slow pace, so that trapped air can exit properly from internal cavities.

4.

After assembly and or test run, plug in/out ports to prevent oil leakage during horizontal storage and transportation.

These recommendations are valid for all large hammers (weight 1000 kg and larger).

Procedure NOTE: check and calibrate all the gauges you are going to use. Change faulty pressure gauges.

NOTE: if the flow to the hammer is adjusted by changing the engine revolutions, always check the flow also at full engine revolutions.

NOTICE: don't use hammer above specified oil flow range.

WARNING: Don't exceed the carrier's main relief valve setting.

1. Check the lines, couplings, clamps etc. to ensure their condition. Replace worn or damaged components and tighten loose joints.

2. Check that there is a pressure relief valve in the hammer line.

3. Make sure that carrier's hydraulic oil temperature is at normal operating level when measuring.

4. Connect the flow meter in place of the hammer. It is preferable to use same hoses and couplings that are used with the hammer, especially in cases when hoses are equipped with quick couplings.

5. Check that the adjustable restriction is open.

6. Start the engine and press the hammer operating switch.

7. Close the hammer line to adjust the crack point of pressure relief valve 50 bar (gauge p2) above the hammer max. operating pressure shown in the technical data.

8. Open the restriction so that the hammer's operating pressure at gauge p2 is reached.

9. Check that the hammer's oil flow is within the limits.

10. Check that the return line back pressure p3 doesn't exceed the values allowed at the hammer oil flow.

11. Check that the hammer's oil flow doesn't increase when the carrier's operating pressure exceeds the pressure in the hammer line (pressure compensated flow control). To do that, drive the boom, stick and bucket cylinders to the tilt position while pressing the hammer operating switch and checking the flow.

12. Open the restriction.

13. Stop the carrier engine.

14. Connect the hammer in place of the flow meter.

15. Measure hammer operating pressure.

16. When installing a new hammer check all the values after working about 50 h with the hammer.

Procedure WARNING: When measuring hammer operating pressure, you are working in hammer's danger area.

Protect yourself against flying debris.

1. Hammer operating pressure must be measured with carrier hydraulic circuit in its optimum operating temperature. Before starting hammer operating pressure measuring procedure, operate carrier until hydraulic oil has warmed sufficiently.

2. Stop the carrier engine.

3. Remove pressure measuring plug (A) and connect a 250 bar pressure gauge with a minimum 10 m hose to high pressure measuring port, BSP 1/4" on check valve cover.

4. Start carrier and adjust engine revolutions. Set engine revolutions to hammer operating revs. If carrier has power/work modes, please select mode intended for hammer work.

5. Position tool for example on a thick steel plate and start to operate the hammer.

6. Read average operating pressure (B) reading on pressure gauge. See figure 2 where is shown the needle fluctuation (A).

NOTE: average operating pressure reading should range between given specifications.

NOTE: when measuring operating pressure by hammering on a steel plate or equivalent hard material, the pressure reading should be in the lower end of the specified pressure range. Hammer's operating pressure tends to raise when working with soft material. See General specification () .

NOTE: if pressure reading is not within specifications, re-adjust pressure control valve spring pre-load and measure operating pressure again. See Hammer - Adjust Pressure control valve (89.700).

7. Stop carrier and remove gauge. Torque plug (A) to specified setting.
