Risks associated with items catching/getting entwined

• Wear suitable clothing. Avoid loose clothing, jewellery, or long hair that could catch in moving parts.

Risks during operation

• Hands may be exposed to cuts, abrasions, or heat damage. Wear suitable gloves.
• Operators must be physically capable of handling the tool's size, weight, and power.
• Hold the tool correctly and be prepared for unexpected movements.
• Maintain a safe stance and balance at all times.
• If an accessory jams, high reaction torques can occur. Use suspension devices or side grips if possible. Use aids to absorb reaction torque.
• Do not touch rotating parts.
• Avoid accidental operation; switch off the tool if air supply is interrupted.
• Use only manufacturer-recommended lubricants.
• Always wear safety glasses (?) and other appropriate personal protective equipment (PPE) such as gloves, protective clothing, dust masks, and safety shoes.

Risks associated with recurring movements

• Work in a comfortable position, holding the tool securely. Avoid awkward positions.
• Change position occasionally during extended use to avoid fatigue.
• If experiencing persistent symptoms (numbness, pain, hearing loss, joint stiffness), stop work, notify employer, and consult a doctor.

Risks associated with accessory parts

• Disconnect from air supply before securing or replacing accessories.
• Use only accessories designed for this machine and specified in these instructions.
• Avoid direct contact with accessories after use, as they may be hot or have sharp edges.

Risks in the workplace

• Be aware of slipping, tripping, and falling hazards, especially from air hoses.
• Proceed carefully in unfamiliar environments; check for hidden risks like power cables or supply lines.
• The tool is not designed for explosive environments or contact with live electrical sources.
• Ensure the work area is free of power cables, gas lines, or water pipes.

Risks associated with dust and vapours

• Dust and vapours may pose health risks (cancer, birth defects, asthma, dermatitis). Conduct a risk assessment and implement controls.
• Minimize dust generation and control it at the source.
• Use and maintain dust collection/extraction systems according to manufacturer instructions.
• Select, maintain, and replace consumables and accessories to minimize dust/vapour generation.
• Use protective breathing apparatus as required by employer or safety regulations.

Risks associated with noise

• Inadequate ear protection can cause lasting hearing damage.
• Conduct a risk assessment for noise and implement control measures (e.g., sound-insulating materials).
• Use ear protection (?) as required.
• Operate and maintain the tool to avoid unnecessarily raising noise levels.
• Ensure the integrated sound absorber is not removed and is in good working order.

Risks associated with vibration

• Vibrations can damage nerves and impair blood circulation.
• Wear warm clothing in cold environments and keep hands warm and dry.
• If experiencing numbness, prickling, or white fingers, stop work immediately, notify employer, and consult a doctor.
• Operate and maintain the tool to avoid unnecessarily raising vibration levels.
• Do not allow the drill bit to rattle against the workpiece.
• Select, maintain, and replace consumables/accessories to avoid increasing vibration.
• Use stands, clamps, or equalizers to support the tool's weight where possible.
• Hold the tool firmly but not too tightly; excessive grip force increases vibration risk.

Additional safety instructions

• Compressed air can cause serious injury.
• When not in use, or before maintenance/repairs, disconnect the air supply, depressurize the hose, and disconnect the tool.
• Never direct the air jet at yourself or others.
• Check hoses and fixtures for good condition and secure connections. Use whip check hose restraints.
• Direct cold exhaust air away from hands.
• Use locking pins with universal swivel couplings.
• Do not exceed the maximum specified pressure.
• Never carry air tools by the hose.
• Secure the tool if operated in a holder to prevent loss of control.
• Observe specific health and safety regulations for compressors and air tools.
• Ensure the maximum supply pressure is not exceeded.
• Do not overload the tool; use it within its designed performance range.
• Use non-hazardous lubricants and ensure adequate ventilation.
• Operate only when focused, alert, and cautious. Never use when tired or under the influence of drugs, alcohol, or medication.
• Ensure the workplace is clean and well-lit.
• Keep air tools away from children.
• Do not store the tool outdoors or in damp conditions without protection.

Operation

Before Using the Tool for the First Time

• Insert plug-in nipple (8) into the compressed air connection (7).

Using the Air Tool

• Use compressed air hoses with an inner diameter of at least 9 mm for optimal performance.
• Ensure the compressed air line does not contain water condensation.
• Regular maintenance with a pneumatic oil lubricator is recommended for tool longevity. This can be achieved by using oiled compressed air (oil-fog lubricator) or by manually applying 3-5 drops of pneumatic oil lubricator every 15 minutes of continuous operation (or about 5 drops if the tool has been unused for several days).
• Allow the tool to run at idle speed only for brief periods.
• To insert a drill bit: Insert the drill bit into the chuck (1) as far as possible. Firmly hold the retaining ring (3) and vigorously turn the sleeve (2) to tighten the drill bit securely.
• To set direction of rotation: Use the rotation selector switch (5).
• Adjust supply pressure: Measure at the air outlet while the tool is switched on. Refer to "Technical Specifications" for maximum permissible pressure.
• Connect the air tool to the compressed air supply.
• To switch on: Press switch (4).
• To switch off: Release switch (4).

Care and Maintenance

• ❗ DANGER: Repairs and maintenance not described here must only be performed by qualified specialists.
• Carry out regular maintenance for safety.
• Check and tighten all screw fittings.
• Clean the filter in the compressed air connection at least once a week.
• It is recommended to install a pressure reducer with an air-water separator and lubricator upstream of the tool.
• If significant air or oil leaks occur, check the tool and have it maintained if necessary (see Section 9. Repairs).
• Check rotational speed regularly and after each use. Perform a simple check on vibration emission.
• Avoid contact with dangerous substances on the tool. Wear suitable PPE and take measures to remove them before maintenance.

• a_h = Vibration emission level
• K_h = Measurement uncertainty (vibration)

Sound level: (EN ISO 15744)

• L_pA = Sound pressure level
• L_WA = Acoustic power level
• K_pA, K_WA = Measurement uncertainty

? Wear ear protectors!
