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 mi-
crons and more than 90% of liquid water. Install the filter as close as possi-
ble to the product and prior to any other air preparation units to avoid pres-
sure drop.
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.

when changing accessories on the tool.
CAUTION Cutting Hazard
Protect hands from drill bits and other sharp objects when changing acces-
sories or during repair work. Sharp objects can cut and cause injuries.
►Always wear protective gloves when changing accessories or during re-
pair work.
►Remove the protective gloves before starting the tool.
1. Position the support handle for either right- or left handed operation.
2. Drain the hose of air pressure before connecting to air supply.
3. 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.
4. Connect the tool to the air supply.
5. Use the appropriate drilling speed for the application.

Operation
Ergonomic guidelines
Consider your workstation as you read through this list of general ergonomic
guidelines and see if you can identify areas for improvement in posture, compo-
nent 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 convenient reach range by determining where parts or tools
should 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 as-
sembly operations.
• When working above shoulder level, reduce the load on the static mus-
cles by reducing 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.
• Make sure to take frequent breaks.
• Avoid extreme arm or wrist postures, particularly for operations requir-
ing a degree of force.
• Adjust for convenient field of vision by minimizing movement of the eyes
and head during the work task.
• Use the appropriate lighting for the work task.
• Select the appropriate tool for the work task.
• Use ear protection equipment in noisy environments.
• Use high-quality inserted tools or consumables to minimize exposure to ex-
cessive levels of vibration.
• Minimize exposure to reaction forces.
• When cutting:
A cut-off wheel can get stuck if the wheel is either bent or if it is not
guided properly. Make sure to use the correct flanges for cut-off wheels
and avoid bending the wheel during cut-off operation.
• When drilling:
The drill might stall when the drill bit breaks through. Makes sure you
use support handles if the stall torque is too high. The safety standard
ISO11148 part 3 recommends using something to absorb the reaction
torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
• When using direct-driven screw or nutrunners:
Reaction forces depend on tool setting and joint characteristics. The abil-
ity to bear reaction forces depends on the operator’s strength and pos-
ture. 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.
• Use dust extraction system or mouth protection mask in dusty environments.

Lubrication instructions
Rust protection and cleaning
Water in the compressed air can cause rust. To prevent rust we strongly recom-
mend to install an air dryer.
Water and particles can cause sticking of vanes and valves. This can be pre-
vented 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.
