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.

Compressed air connection
WARNING Compressed air can cause serious injury
►Always shut off the air supply, drain hose of air pressure and disconnect
the tool from air supply; when not in use, before making any adjustments
to the product - for example changing accessories, or when making re-
pairs.
WARNING Whipping hoses can cause serious injury
►Always make sure that there are no damaged or loose hoses or fittings.
WARNING Compressed Air
High air pressure can cause severe damage and injury.
►Do not exceed maximum air pressure.
For correct air pressure and hose size, see section Technical data.
Make sure that the hose and couplings are clean and free from dust before
connecting to the tool.
Installation instructions
Installation of vibrating tools
It is recommended that a minimum length of 300 mm (12") of flexible hose for
compressed air is inserted between a vibrating tool and the quick-action cou-
pling.

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.

Service
Maintenance instructions
Overhaul and lubrication
If the tool is normally used as a heavy-duty tool it should be dismantled, over-
hauled and cleaned after 120 hours in operation. If the tool is not operating cor-
rectly, it should be taken out of service for inspection. Use lubricants of good
quality. The air motor oils and greases mentioned in the grease guide are exam-
ples of lubricants which are recommended.
At the overhaul, do the following:
• Inspect all disassembled parts for wear.
• Replace the cylinder ball and all the o-rings.
• Clean the dismantled parts with highly refined paraffin.
• Lubricate sliding parts before assembly.
NOTICE Risk of Cylinder Ball Damage
A metallic cylinder ball will damage the cylinder valve seat and piston valve
pin.
►Do not replace the plastic cylinder ball with a metallic version.
Lubrication instructions
Lubricating guide
Use lubricants of good quality. The oils and greases listed in the lubrication ta-
ble are examples of lubricants that can be recommended.
