The 9033 is an all hydraulic machine. It consists of an undercarriage fitted with tracks and a turntable bearing which supports the upperstructure frame. The upperstructure frame supports the attachment, at the front end of the machine, plus the engine, hydraulics and cab. When the operator works the controls, the engine-driven variable flow pump delivers hydraulic fluid under pressure to the control valves. The control valves distribute the hydraulic fluid to the various cylinders and hydraulic motors employed. A cooling system and oil cooler keep the fluid temperature down to normal working temperature.

the tool is in contact with some part of the machine.

•

Move everybody away before operating the hydraulic breaker.

Never immerse the hydraulic breaker in water as this could cause damage.

•

Never use the hydraulic breaker to sweep the ground to spread rubble, to push objects or carry out lifting operations.

Do not operate the hydraulic breaker with the attachment cylinders up to the end of their stroke (extended or retracted).

•

Place the tool against the object at a 90 degree angle. Avoid small irregularities on the object which will break easily and cause either idle strokes or an incorrect working angle.

When demolishing vertical structures (e.g brick walls), place the tool against the wall at a 90 degree angle.

Use a safety screen to protect yourself from flying debris. Keep the cab windows closed during operation.

•

Do not strike in one spot for more than 15 seconds at a time. If the object does not break, or if the tool does not penetrate, stop the breaker and change the position of the tool.

For the hydraulic breaker to be most effective when breaking boulders work progressively in small steps from the outer edge towards the middle.

•

•

•

•

When breaking hard or frozen ground, use the benching method. Start by clearing a small area working from the edge. Then continue by breaking material towards the open area.

Do not operate the hydraulic breaker in the air, with nothing to hit. Frequent idle strokes have a deteriorating effect on the hydraulic breaker.

When breaking concrete, hard or frozen ground, never strike and pry with the tool at the same time. The tool may snap off. Bending may be caused by stones inside hard or frozen ground. Be careful and stop striking if you encounter sudden resistance under the tool.

Keep the tool at a 90 degree angle at all times. If the object moves or if its surface breaks, correct the angle immediately. Keep the hydraulic hydraulic force and tool aligned.

The tool shank should be kept well greased during operation. Regular visual checks should be made during operation.

•

Listen to the noise the hydraulic breaker makes while you are using it. If the pitch of the noise rises and, at the same time, the force of impact diminishes, this means that the tool is not properly aligned with the material and/or that there is not enough downward force on the tool. Realign the tool and press it firmly against the material.

WARNING: Whenever load handling operations are to be carried out, it is imperative to adhere strictly to the instructions given in this manual and local legislation.

Alt= to hide template information Alt+ to display template information

For all handling operations (tubes, concrete pipe connections, shoring material, etc...) the machine must be equipped with safety valves, an overload indicator, a load attachment point and a load chart corresponding to the type of machine and to its attachments.

IMPORTANT: No system or device may be substituted for safety valves when load handling.

When handling loads, make sure you do the following : - Park the machine on flat, firm, level ground.

- Use the load fixing point (eye on the bucket connecting rod or the connecting rod/bucket linkage pin) depending on machine serial number. See “Load handling eye” in the “Controls/Instruments/Accessories” Section and “Maximum loads” in the “Specifications” Section. It is strictly forbidden to weld hooks or lugs to the bottom plate of buckets.

- Use slings and chains in perfect condition, suitable for lifting the load to be handled and fitted with a safety device to prevent accidental opening.

BREAKING TECHNIQUES ON A HYDRAULIC BREAKER (optional)

Alt= to hide template information Alt+ to display template information

To increase the hydraulic breaker’s working life, pay particular attention to correct working methods and to the correct choice of tool for the job. There are essentially two ways of breaking with a hydraulic breaker.

Breaking by penetration (or cutting) In this form of breaking a moil point or chisel tool is forced inside the material. This method is most effective in soft, layered or plastic, low abrasive material. The high impact rate of the small breakers makes them ideal for penetrative breaking.

Breaking by impact With impact breaking, the material is broken by transferring very strong mechanical stress waves from the tool into the material. The best possible energy transfer between the tool and the object is achieved with a blunt tool.

Impact breaking is most effective in hard, brittle and very abrasive materials. The use of a chisel tool in hard material will cause the sharp edge to wear very quickly. The high impact energy of the big breakers makes them ideal for impact breaking.

Fuel

Fuel storage

Use fuel which is to ASTM (American Society for Testing and Materials) D975 standard.

Long storage can lead to the accumulation of impurities and condensation in the fuel. Engine trouble can often be traced to the presence of water in the fuel.

When the temperature is very cold, the use of a mixture of N°1 and N°2 fuel is permitted. See your fuel vendor for winter fuel requirements in your area.

If the temperature falls below the fuel cloud point (point at which wax begins to form) the wax crystals will cause power loss or will prevent the engine from starting.

IMPORTANT: In cold weather, fill the fuel tank at the end of the day’s work, in order to prevent the formation of condensation.

The storage tank must be placed outside and the temperature of the fuel should be kept as low as possible. Drain off water and impurities regularly.

Anti-freeze/Anti-corrosion Use anti-freeze in all seasons to protect the cooling system from corrosion and all risk of freezing.

For areas where ambient temperature is over -36°C, use a blend of 50% ethyleneglycol based anti-freeze.

For areas where the temperature is below -36°C, it is advisable to use a blend of 40% water and 60% anti-freeze.

ENVIRONMENT Contact your local ecological recycling centre or your CASE Dealer to obtain information on the correct method of disposing of these materials.

Template Name: OM_1_col Template Date: 1994_04_29

Before carrying out any maintenance operation on this machine and before disposing of used fluids or lubricants, always think of the environment. Never throw oil or fluid on the ground and never place it in leaking receptacles.

TRIM THIS EDGE

Use grade N°2 fuel. The use of other types of fuel can result in a loss of power and may cause high fuel consumption.

GREASING THE HYDRAULIC BREAKER (optional) Template Name: OM_1_col Template Date: 1994_04_29

Greasing intervals

Correct greasing

1.

The tool shank must be well lubricated before installing.

2.

Press the grease gun between 5 to 10 times, at regular intervals, to grease the tool bushing and the tool.

While greasing, the hydraulic breaker must be standing upright resting on the tool to ensure that the grease will penetrate downwards between the tool and the bushing.

3.

Adapt the intervals and the quantity of grease to the wear rate of the tool and to working conditions. This can be anything between every two hours and once a day, depending on the type of material (rock/concrete) being broken.

TRIM THIS EDGE

Insufficient greasing or improper grease may cause :

• •

Abnormal wear of tool bushing and tool Tool breakage

Do not fill the space between the piston and the tool with grease. A lower piston seal failure can result and the hydraulic breaker will eventually leak oil.

Grease points Use the following grease: - EP NLGI grade 2 (for temperate and hot climates) -20°C to +60°C - EP NLGI grade 0 (for cold climates) -40°C to +20°C Every 2 hours
