The required degree of protection should be assessed for every specific application.
When doing so danger to other persons must also be considered.
Make sure that the workpiece is securely fixed.
Entanglement hazards
Risk of asphyxiation, degloving injuries and cuts, if loose clothing personal jewellery,
necklaces, hair or gloves are not kept away from the tools and accessories.
Gloves can become caught in the rotating drive leading to severed or broken fingers.
Keep the hands away from the rotating drives.
Rotating drive bushings and drive extensions can be easily caught on rubber-coated
or metal-reinforced gloves. Never hold the drive or the drive extension.
Operating hazards
Operation and maintenance personnel must be physically able to handle the mass,
the weight and the force of the tool.
Hold the tool correctly; be ready to counteract normal or sudden movements and

the pneumatic tool, as well as consumables; do not use other types or sizes of
accessories and consumables.
During and after use avoid direct contact with the tool, since it may be hot or sharp.
Hazards in the workplace
Slips, trips and falls are the main causes of workplace accidents. Watch out for
slippery surfaces, which arise when using the tool, as well as tripping hazards,
caused by the air line or the hydraulic hoses.
The pneumatic tool is not designed for use in explosion hazard areas and is not
insulated against contact with electrical power.
Make sure that no electrical cables, gas pipes and similar are present, which could
present a hazard when using the tool if they are damaged.
Risks from dust and vapours
The risk assessment should take into account the dust and the possibility of stirring
up existing dust when using the tool.
Point the exhaust in such a way that dust being stirred up in dusty environments is
minimised.
Hazards from noise
The noise level when using the pneumatic tool is 96.0 dB (A)
Always wear professional hearing protectors when working with pneumatic tools.
If working regularly in noisy areas, according to the workplace safety regulations, a
preventative investigation for working in noisy areas should be offered.
Long-term exposure to high noise levels can cause permanent, disabling hearing
damage and other problems such as tinnitus (ringing, buzzing, whistling or humming
in the ears). For this reason a risk assessment and the implementation of suitable
controls for these hazards is essential.
Suitable controls for reducing the risk can include measures such as for example
using damping materials to prevent workpieces vibrating.
Operate and maintain the pneumatic tool as recommended in the operating
instructions, in order to avoid an unnecessary increase in the noise level.
Select maintain and replace the consumables/inserts as recommended in the
operating instructions, to avoid unnecessary increase of the noise level.
Vibration hazards
The effects of vibration can cause nerve damage and impaired blood supply to the
hands and arms.
When working in cold environments wear warm clothing and keep your hands warm
and dry.
If you feel numbness, prickling, pain will see a white appearance of the skin in
fingers or hands, stop the use of the pneumatic tool, inform your employer and seek
medical advice.
Operate and maintain the pneumatic tool as recommended in the operating
instructions, in order to avoid an unnecessary increase of the vibration values.

Hold the tool with a loose, but secure grip - when doing so take into account the
necessary hand reaction forces, since the risk of vibration is generally higher when
the gripping force is higher.
Additional safety information for pneumatic tools
Compressed air can cause serious injuries.
Always switch off the compressed air supply, release the air pressure from the hose,
and disconnect the tool from the compressed air supply, if it is not being used,
before replacing accessory parts, or before carrying out repairs.
Never point compressed air at yourself or other persons.
Whipping hoses can cause severe injuries. Always check hoses and screw fittings for
damage and secure seating.
Cold compressed air should be pointed away from the hands.
For impact and impulse wrenches do not use quick close couplings on the tool input.
Use hose screw fittings in hardened steel (or material with comparable impact
resistance).
If universal rotary couplings (claw couplings) are used, locking pins must be installed
and anti-whipping safety cables used, to prevent possible failure of the connection
between hose and tool and hose and hose.
Never use worn or a poorly fitting socket inserts or extensions, since this can cause a
significant increase in vibrations. If possible use ferrule-type couplings.
Support the weight of the tool, where possible in a stand, clamp or stabiliser.
Do not exceed the maximum air pressure indicated on the tool.
Never carry a pneumatic tool by the hose.

Connect the tool to the compressed air hose of the recommended size.
NOTE: Using a quick-coupling set makes connection easier.
Using compressed air filters and compressed air line
lubricators is recommended.
For use:
Switch on the air compressor and allow it to fill up the reservoir tank.
Set the regulator of the air compressor to 6.2 bar (90 psi). This tool works with a
maximum pressure of 6.2 bar (90 psi).
When using rotary tools check for correct direction of rotation before using the tool.
Make sure that the inserted tool is sitting firmly on the square drive (impact/ratchet
socket)
Adjust the direction of rotation if necessary:
Move the switch/lever as marked on the tool.
「F」（Forwards）- Clockwise direction of rotation as viewed from the user’s position.
「R」（Backwards）- Anticlockwise direction of rotation as viewed from the user’s
position.
Note: On some tools this may be marked with the combination of 「L」and「R」. In this case 「
R」(right) stands for the forward direction and 「L」(left) for the reverse direction.
Set the rotation/oscillation speed, if applicable:
Using numbers: a larger number indicates a higher setting and vice versa.
Using symbols: larger size of the symbol indicates a higher setting and vice versa.
Note: Always start operation with a low setting.
Allow the tool to come to a complete stop, before changing the direction of rotation.
To start or stop.
The tool is fitted with a trigger/lever for stopping. Pull the trigger (or press the lever down),
to start the tool. The tool stops running, when the trigger/lever is released.
Note: With certain types of pneumatic tools, due to inertia it can take a few seconds until
the tool comes to a complete standstill.

Always disconnect the compressed air supply before lubricating, installing, removing or
adapting the tool.
Once the work has finished, switch off the air compressor and store it as described in
the operating instructions of the air compressor.
Always use clean, dry air with a maximum air pressure of 6.2 bar (90 psi). Dust,
corrosive vapours and excessive moisture can destroy the internal parts of a pneumatic
tool.
Do not remove any markings. Replace a marking if damaged.
Keep hands, loose clothing and long hair away from the moving parts of the tool.
Maintenance and care
General tips
Hold the tool and allow it to run without load to check the vibration level before using
the tool. If an excessive level of vibration is noticed, then this is a sign that maintenance
or repair may be required.
Before use check the idle speed of the tool if you hear noise being produced by the tool.
It is recommended to check the idle speed of the tool regularly and after every
maintenance activity using a tachometer and stroboscope.
Keep the tool clean after each use, to avoid the risk of exposure to hazardous
substances which may be deposited on the tool during working processes.
Follow the locally applicable regulations regarding waste disposal.
Always use the accessories recommended by your dealer.
Before carrying out maintenance work on the tool always disconnect the compressed air
supply first.
Lubrication
Pneumatic tools must be lubricated regularly during their complete service life. The
pneumatic motor and the bearing use compressed air to drive the tool. Since moisture in
the compressed air causes the pneumatic motor to rust, the motor
must be lubricated daily. An inline-oiler is recommended.
The pneumatic motor is lubricated manually as follows:
Disconnect the tool from the air supply and hold it so that the air
inlet points upwards.
Press the trigger and put one to two drops of pneumatic tool oil into the air inlet.
Connect the tool to a compressed air source, cover the outlet with a cloth and let is run
for a few seconds.
Do not lubricate tools with flammable of volatile liquids such as paraffin, diesel or jet
fuel.
