Service Overview

Preventive maintenance

Preventive maintenance

Make sure to perform a preventive maintenance every 6 months. If it is used in heavy duty conditions or not running properly, it should be removed from operation for inspection more often.

Installation

Installation Requirements

Air Quality

For optimum performance and maximum product life we recommend the use of compressed air with a maximum dew point of +10°C (50°F). We also recommend to install an Atlas Copco refrigeration type air dryer.
Use a separate air filter which removes solid particles larger than 30 microns and more than 90% of liquid water. Install the filter as close as possible to the product and prior to any other air preparation units to avoid pressure drop.

For impulse/impact tools make sure to use lubricators adjusted for these tools. Regular lubricators will add too much oil and therefore decrease the tool performance due to too much oil in the motor.

Make sure that the hose and couplings are clean and free from dust before connecting to the tool.

Both lubricated and lubrication free products will benefit from a small quantity of oil supplied from a lubricator.

Air Lubrication Guide

Recommended air lubricators:

Atlas Copco Optimizer (1 liter) 9090 0000 04
Q8 Chopin 46
Shell Air Tool Oil S2 A 320

Compressed Air Connection

WARNING

Risk of severe injury

Air under pressure can cause injury.

Always shut off the air supply when not in use or before any adjustments.
Drain the hose of air pressure and disconnect the tool from air supply when not in use or before any adjustments.
Always use the correct hose size and air pressure for the tool.

WARNING

Compressed Air

High air pressure can cause severe damage and bodily injury.

Do not exceed maximum air pressure.
Make sure that there are no damaged or loose hoses or fittings.

For correct air pressure and hose size, see the Technical Product Data on - https://servaid.atlascopco.com or www.atlascopco.com.

Make sure that the hose and couplings are clean and free from dust before connecting to the tool.

WARNING

Always wear impact-resistant eye and face protection when involved with or near the operation, repair or maintenance of the tool or when changing accessories on the tool.

CAUTION

Cutting Hazard

Protect hands from drill bits and other sharp objects when changing accessories or during repair work. Sharp objects can cut and cause injuries.

Always wear protective gloves when changing accessories or during repair work.
Remove the protective gloves before starting the tool.

Position the support handle for either right- or left handed operation.
Drain the hose of air pressure before connecting to air supply.
Tighten the drill bit in place with a chuck. A keyed chuck uses a rotary key to tighten and loosen the chuck. A keyless chuck is operated by hand.

Never drill a hole that is larger than the rated capacity for the drill.

The motor requires no additional lubrication during operation.
Connect the tool to the air supply.
Use the appropriate drilling speed for the application.
To start the tool, press the trigger.

When lubrication is recommended - only use lubricants recommended by Atlas Copco.

Operation

Ergonomic Guidelines

Consider your workstation as you read through this list of general ergonomic guidelines to identify areas for improvement in posture, component placement, or work environment.

Take frequent breaks and change work positions frequently.
Adapt the workstation area to your needs and the work task.
- Adjust for a convenient reach range by determining where parts and tools need to be located to avoid static load.
- Use workstation equipment such as tables and chairs appropriate for the work task.
Avoid work positions above shoulder level or with static holding during assembly operations.
- When working above shoulder level, reduce the load on the static muscles by lowering the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.
- Take frequent breaks.
- Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.
Adjust for a convenient field of vision that requires minimal eye and head movements.
Use appropriate lighting for the work task.
Select the appropriate tool for the work task.
In noisy environments, use ear protection equipment.
Use high-quality inserted tools and consumables to minimize exposure to excessive levels of vibration.
Minimize exposure to reaction forces.
- When cutting:
  
  A cut-off wheel can get stuck if the cut-off wheel is bent or not guided properly. Use the correct flange for the cut-off wheel and avoid bending the cut-off wheel during operation.
- When drilling:
  
  The drill might stall when the drill bit breaks through. Use support handles if the stall torque is high. The safety standard ISO11148 part 3 recommends using a device to absorb a reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
- When using direct-driven screwdrivers or nutrunners:
  
  Reaction forces depend on the tool settings and joint characteristics. Strength and posture determine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the operator's strength and posture and use a torque arm or reaction bar if the torque is too high.
In dusty environments, use a dust extraction system or wear a mouth protection mask.

Lubrication Instructions

Rust Protection and Cleaning

Water in the compressed air can cause rust. To prevent rust we strongly recommend to install an air dryer.

Water and particles can cause sticking of vanes and valves. This can be prevented by installing an air filter close to the product to avoid pressure drop.

Before longer standstills always protect your tool by adding a few drops of oil into the air inlet. Run the tool for 5–10 seconds and absorb any access oil at the air outlet in a cloth.

NOTICE

Do not try to clear the air path using sharp tools.

The air inlet is equipped with a strainer. If this is punctured, foreign objects may harm the valves, resulting in overspeed.
