Service overview

Maintenance and service instructions

The service must only be done by authorized workshops or qualified ser-

vice technicians.

WARNING Polymer hazard

The vanes in this product contain PTFE (a synthetic fluoropolymer). Due to

wear, there might be PTFE particles inside the product. Heated PTFE can

produce fumes which may cause polymer fume fever with flu-like symp-

toms, especially when smoking contaminated tobacco.

Health and Safety recommendations for PTFE must be followed when han-

dling vanes and other components:

►Do not smoke when servicing this product

►PTFE-particles must not come in contact with open fire, glow or heat

►Motor components must be washed with cleaning fluid and not blown

clear with an air line

►Wash your hands before starting any other activity

Replacement of vanes

Replace the vanes in the motor when a power drop of the tool is experienced. If

the vanes are not replaced in time other motor parts may be damaged. For in-

creased life length of the vanes use an oil lubricator to dose oil into the air inlet.

Service recommendations

Preventive maintenance is recommended at regular intervals. See the detailed

information on preventive maintenance. If the product is not working properly,

take it out of service and inspect it.

If no detailed information about preventive maintenance is included, follow

these general guidelines:

• Clean appropriate parts accurately

• Replace any defective or worn parts

G2422-1 EN Installation

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 EN G2422-1

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.
