DANGER: Whipping air hose
A compressed air hose that comes loose can lash around and cause personal injury or death. To reduce this risk:

• Check that the compressed air hose and the connections are not damaged, replace if necessary.
• Check that all compressed air connections are properly attached.
• Never carry a pneumatic machine by the air hose.
• Never attempt to disconnect a compressed air hose that is pressurized. First switch off the compressed air at the compressor and then bleed the machine by activating the start and stop device.
• Do not use quick disconnect couplings at tool inlet. Use hardened steel (or material with comparable shock resistance) threaded hose fittings.
• Whenever universal twist couplings (claw couplings) are used, we recommend that lock pins are installed and whipcheck safety cables are used to safeguard against possible hose to tool and hose to hose connection failure.
• Never point a compressed air hose at yourself or anyone else. To avoid the risk of getting injured, never use compressed air to blow for example dust, dirt etc. from your clothes.

WARNING: Ejected insertion tool If the tool retainer on the machine is not in a locked position, the inserted tool can be ejected with force, which can cause personal injury. Never start the machine while changing the insertion tool.

• Before changing the insertion tool or accessories, stop the machine, switch off the power supply and bleed the machine by activating the start and stop device. Never point the inserted tool at yourself or anyone else.
• Make sure that the insertion tool is fully inserted and the tool retainer is in a locked position before the machine is started.
• Check the locking function by pulling the inserted tool outwards forcefully.

WARNING: Moving or slipping insertion tool .
An incorrect dimension of the inserted tool’s shank can result in that the inserted tool is lost or is slipping out during operation. Risk of severe injury or crushed hands and fingers.

• Check that the insertion tool has the shank length and dimensions that the machine is intended for.
• Never use an insertion tool without a collar.

Operation, precautions

If an working tool comes into contact with explosives or explosive gases, an explosion could occur. When working on certain materials and when using certain materials in machine parts, sparks and ignition can occur. Explosions will lead to severe injuries or death.

• Never operate the machine in any explosive environment.
• Never use the machine near flammable materials, fumes or dust.
• Make sure that there are no undetected sources of gas or explosives.

The inserted tool is exposed to heavy strains when the machine is used. The inserted tool may break due to fatigue after a certain amount of use. If the inserted tool breaks or gets stuck, there may be sudden and unexpected movement that can cause injuries. Furthermore, losing your balance or slipping may cause injury.

Some dusts and fumes created by drilling, breaking, hammering, sawing, grinding and other construction activities contain substances known to the State of California and other authorities to cause respiratory disease, cancer, birth defects, or other reproductive harm. Some examples of such substances are:

• Crystalline silica, cement, and other masonry products.
• Arsenic and chromium from chemically-treated rubber.
• Lead from lead-based paints.

Dust and fumes in the air can be invisible to the naked eye, so do not rely on eye sight to determine if there is dust or fumes in the air. To reduce the risk of exposure to dust and fumes, do all of the following:

• Perform site-specific risk assessment. The risk assessment should include dust and fumes created by the use of the machine and the potential for disturbing existing dust.
• Use proper engineering controls to minimize the amount of dust and fumes in the air and to minimize build-up on equipment, surfaces, clothing, and body parts. Examples of controls include: exhaust ventilation and dust collection systems, water sprays, and wet drilling. Control dusts and fumes at the source where possible. Make sure that controls are properly installed, maintained and correctly used.
• Wear, maintain and correctly use respiratory protection as instructed by your employer and as required by occupational health and safety regulations. The respiratory protection must be effective for the type of substance at issue (and if applicable, approved by relevant governmental authority).
• Work in a well ventilated area.
• If the machine has an exhaust, direct the exhaust so as to reduce disturbance of dust in a dust filled environment.
• Operate and maintain the machine as recommended in the operating and safety instructions
• Select, maintain and replace consumables/ working tools/ other accessories as recommended in the operating and safety instructions. Incorrect selection or lack of maintenance of consumables/ inserted tools/ other accessories may cause an unnecessary increase in dust or fumes.
• Wear washable or disposable protective clothes at the worksite, and shower and change into clean clothes before leaving the worksite to reduce exposure of dust and fumes to yourself, other persons, cars, homes, and other areas.
• Avoid eating, drinking, and using tobacco products in areas where there is dust or fumes.
• Wash your hands and face thoroughly as soon as possible upon leaving the exposure area, and always before eating, drinking, using tobacco products, or making contact with other persons.
• Comply with all applicable laws and regulations, including occupational health and safety regulations.
• Participate in air monitoring, medical examination programs, and health and safety training programs provided by your employer or trade organizations and in accordance with occupational health and safety regulations and recommendations. Consult with physicians experienced with relevant occupational medicine.
• Work with your employer and trade organization to reduce dust and fume exposure at the worksite and to reduce the risks. Effective health and safety programs, policies and procedures for protecting workers and others against harmful exposure to dust and fumes should be established and implemented based on advice from health and safety experts. Consult with experts.
• Residues of hazardous substances on the machine can be a risk. Before undertaking any maintenance on the machine, clean it thoroughly.

WARNING: Projectiles
Failure of the work piece, of accessories, or even of the machine itself may generate high velocity projectiles. During operating, splinters or other particles from the working material may become projectiles and cause personal injury by striking the operator or other persons. To reduce these risk:

• Use approved personal protective equipment and safety helmet, including impact resistant eye protection with side protection.
• Make sure that no unauthorised persons trespass into the working zone.
• Keep the workplace free from foreign objects.
• Ensure that the work piece is securely fixed.

WARNING: Splinters hazard
Using the insertion tool as a hand struck tool can result in splinters hitting the operator and can cause personal injury.

• Never use an insertion tool as a hand struck tool. They are specifically designed and heat-treated to be used only in a machine.

WARNING: Slipping, tripping and falling hazards
There is a risk of slipping or tripping or falling, for example tripping on the hoses or on other objects. Slipping or tripping or falling can cause injury. To reduce this risk:

• Always make sure that no hose or other object is in your way or in any other person’s way.
• Always make sure you are in a stable position with your feet as far apart as your shoulders width and keeping a balanced body weight.

WARNING: Motion hazards

When using the machine to perform work-related activities, you may experience discomfort in the hands, arms, shoulders, neck, or other parts of the body.

WARNING: Vibration hazards
Normal and proper use of the machine exposes the operator to vibration. Regular and frequent exposure to vibration may cause, contribute to, or aggravate injury or disorders to the operator’s fingers, hands, wrists, arms, shoulders and/or nerves and blood supply or other body parts, including debilitating and/or permanent injuries or disorders that may develop gradually over periods of weeks, months, or years. Such injuries or disorders may include damage to the blood circulatory system, damage to the nervous system, damage to joints, and possibly damage to other body structures. If numbness, persistent recurring discomfort, burning sensation, stiffness, throbbing, tingling, pain, clumsiness, weakened grip, whitening of the skin, or other symptoms occur at any time, when operating the machine or when not operating the machine, stop operating the machine, tell your employer and seek medical attention. Continued use of the machine after the occurrence of any such symptom may increase the risk of symptoms becoming more severe and/or permanent. Operate and maintain the machine as recommended in these instructions, to prevent an unnecessary increase in vibration. The following may help to reduce exposure to vibration for the operator:

• Let the tool do the job. Use a minimum hand grip consistent with proper control and safe operation.
  If the machine has vibration absorbing handles, keep them in a central position, avoid pressing the handles into the end stops.

• When the percussion mechanism is activated, the only body contact with the machine you should have are your hands on the handle or handles. Avoid any other contact, for example supporting any part of the body against the machine or leaning onto the machine trying to increase the feed force. It is also important not to keep the start and stop device engaged while extracting the tool from the work surface.

• Make sure that the inserted tool is well-maintained (including sharpness, if a cutting tool), not worn out, and of the proper size. Insertion tools that are not well-maintained, or that are worn out, or that are not of the proper size result in longer time to complete a task (and a longer period of exposure to vibration) and may result in or contribute to higher levels of vibration exposure.

• Immediately stop working if the machine suddenly starts to vibrate strongly. Before resuming the work, find and remove the cause of the increased vibrations.

• Never grab, hold or touch the inserted tool when using the machine.

• Participate in health surveillance or monitoring, medical exams and training programs offered by your employer and when required by law.

• When working in cold conditions wear warm clothing and keep hands warm and dry.

• The exhaust air is strongly chilled and shall not make contact with the operator. Always direct the exhaust air away from hands and body.

See the “Noise and vibration declaration statement” for the machine, including the declared vibration values. This information can be found at the end of these Safety and operating instructions.

• Comply with the recommended air-pressure when operating the machine. Either higher or lower air-pressure has the potential of resulting in higher levels of vibration.

DANGER: Electrical hazard
The machine is not electrically insulated. If the machine comes into contact with electricity, serious injuries or death may result.

• Never operate the machine near any electric wire or other source of electricity.
• Make sure that there are no concealed wires or other sources of electricity in the working area.

Overview

To reduce the risk of serious injury or death to yourself or others, read the Safety instructions section found on the previous pages of this manual before operating the machine.
Design and function
The CP 4608 and CP 4611 are designed for medium to heavy demolition, cutting rivets and bolts, and other cutting and ripping operations. The machine can be used both horizontally and vertically. No other use is permitted. Recommended insertion tools are listed in the spare parts list.
NOTICE: Do not start the machine without an inserted tool fitted. Starting the machine without an inserted tool will cause damage to the impact mechanism.

CPS
As part of the controlled power system (CPS), the CP 4608 and CP 4611 monitor the wear of the bumper and automatically reduces the impact energy when the bumper is worn out.

Intact bumper

Worn out bumper

• A. Lower sleeve
• B. Bumper
• C. Upper sleeve
• D. Cylinder
• E. Insertion tool
• F. Retainer
• G. Bridge
• H. Piston
• I. Wear indicating groove
• J. Bleeding ports

Function
When the buster is exposed to back hammering the impact energy is absorbed by the bumper. Due to the impact energy the bumper wears away and causes the upper sleeve and the lower sleeve to move outwards. At a certain degree of wear of the bumper, the bleeding ports (J) are opened due to the outward movement of the upper and lower sleeves, causing a reduction of the impact energy. This energy reduction works only when the buster is exposed to back hammering. If the insertion tool is pressed firmly against the surface the buster will start again.

Replacement of the bumper
As soon as the buster is starting to run irregularly or stops when exposed to back hammering, the bumper has to be replaced. Continuing to use the buster when the energy reduction is effective will cause damage to the retainer and cylinder. When the wear indicating groove (I) on the lower sleeve appears from the retainer. It indicates that the bumper is completely worn out and that the use of the buster should be stopped and the bumper replaced.

Main parts

• A. Start and stop device (trigger)
• B. Handle
• C. Cylinder
• D. Tool retainer
• E. Air inlet

Labels

The machine is fitted with labels containing important information about personal safety and machine maintenance. The labels must be in such condition that they are easy to read. New labels can be ordered from the spare parts list.

Data plate

• A. Machine type
• B. Maximum permitted compressed air pressure
• C. Serial number
• D. The warning symbol together with the book symbol means that the user must read the safety and operating instructions before the machine is used for the first time.
• E. The CE symbol means that the machine is EC-approved. See the EC declaration which is delivered with the machine for more information. If the CE symbol is missing, it means that the machine is not EC-approved.

Noise level label

The label indicates the guaranteed noise level corresponding to EC-directive 2000/14/EC. See “Technical data” for accurate noise level.
Safety label
To avoid injury, before using or servicing tool, read and understand separately provided safety instructions.

Installation

Hoses and connections

1. A. Compressed air source
2. B. Water separator (optional)
3. C. Oiler (optional)
4. D. Max. 10 feet (3 meter) compressed air hose between the oiler and the machine.

• Check that you are using the correct recommended operating pressure, 87 psig (6 bar (e)).
• The maximum permissible air pressure, 90 psig (6.2 bar (e)), must not be exceeded.
• Blow any impurities out of the compressed air hose before connecting it to the machine.
• Select the correct dimension and length for the compressed air hose. For hose lengths up to 100 feet (30 meters), a hose with a minimum internal diameter of 3/4 in. (19 mm) should be used. If the hose length is between 100 and 330 feet (30 and 100 meters), a hose with a minimum internal diameter of 1 in. (25 mm) should be used.

Connecting a water separator

The length of the air hose between the compressor and the water separator must be such that the water vapour is cooled and condenses in the hose before reaching the water separator. If the ambient temperature is below 32 °F (0 °C) the hose must be short enough to prevent the water from freezing before reaching the water separator.

Lubrication

The lubricant is important for the machine’s function and has a great impact on the service life. In order to supply the correct volume of oil, an oiler should be connected to the air hose. The use of a Chicago Pneumatic air line oiler is recommended. To guarantee good lubrication, the length of the air hose between the oiler and the pneumatic tool should not exceed 10 feet (3 m). Too much lubrication can cause starting problems, low power or uneven performance. Use a synthetic lubricant such as CP Airolene Plus Tool Oil or mineral oil with the properties recommended in the table below.

Noise and vibration declaration statement

Guaranteed sound power level Lw according to EN ISO 3744 in accordance with directive 2000/14/EC. Sound pressure level Lp according to EN ISO 11203. Vibration value A and uncertainty B determined according to EN ISO 20643. See table “Noise and vibration data” for the values of A, B, etc. These declared values were obtained by laboratory type testing in accordance with the stated directive or standards and are suitable for comparison with the declared values of other tools tested in accordance with the same directive or standards. These declared values are not suitable for use in risk assessments and values measured in individual work places may be higher. The actual exposure values and risk of harm experienced by an individual user are unique and depend upon the way the user works, in what material the machine is used, as well as upon the exposure time and the physical condition of the user, and the condition of the machine. We, Atlas Copco Airpower NV, cannot be held liable for the consequences of using the declared values, instead of values reflecting the actual exposure, in an individual risk assessment in a work place situation over which we have no control. This tool may cause hand-arm vibration syndrome if its use is not adequately managed. An EU guide to managing hand-arm vibration can be found at http://www.humanvibration.com/humanvibration/EU/VIBGUIDE.html
We recommend a programme of health surveillance to detect early symptoms which may relate to vibration exposure, so that management procedures can be modified to help prevent future impairment.
