the following:
SAVE THESE INSTRUCTIONS
6
General
a.
To reduce the risks of electric shock, fire, and
injury to persons, read all the instructions before using the tool.
The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or battery-operated (cordless) power tool.
– Only trained and qualified persons are permitted
to set up, adjust and operate this compressed air
tool. Persons without the relevant qualifications
and training are more likely to cause accidents.
– This compressed air tool may not be modified.
Modifications may reduce the effectiveness of
safety devices and pose a greater risk to operating personnel.
– Keep all of the attached documents and pass on
the documentation if the machine changes own-
ership.
– Never use a damaged compressed air tool.
– Regularly inspect compressed air tool. The com-
pressed air tool must be marked with clearly leg-
ible rated values and markings. Replacement
signs can be ordered from the manufacturer.
1 WORK AREA
a.
Keep the work area clean and well lighted.
Cluttered benches and dark areas increase the risks
of electric shock, fire, and injury to persons.
b.
Do not operate the tool in explosive atmospheres, such as in the presence of flammable
liquids, gases, or dust.
The tool is able to create
sparks resulting in the ignition of the dust or
fumes.
c.
Keep bystanders, children, and visitors away
while operating the tool.
Distractions are able to
result in the loss of control of the tool.
2 PERSONAL SAFETY
a.
Stay alert. Watch what you are doing and use
common sense when operating the tool. Do not
use the tool while tired or under the influence of
drugs, alcohol, or medication.
A moment of inattention while operating the tool increases the risk
of injury to persons.
b.
Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep hair, clothing,
and gloves away from moving parts.
Loose
clothes, jewelry, or long hair increases the risk of
injury to persons as a result of being caught in
moving parts.
c.
Avoid unintentional starting. Be sure the switch
is off before connecting to the air supply.
Do not
carry the tool with your finger on the switch or
connect the tool to the air supply with the switch
on.
d.
Remove adjusting keys and wrenches before
turning the tool on.
A wrench or a key that is left
attached to a rotating part of the tool increases
the risk of personal injury.
e.
Do not overreach. Keep proper footing and balance at all times.
Proper footing and balance en-
ables better control of the tool in unexpected
situations.
f.
Use safety equipment.
A dust mask, non-skid
safety shoes and a hard hat must be used for the
applicable conditions.
g.
Always wear eye protection.
h.
Always wear hearing protection when using the
tool.
Prolonged exposure to high intensity noise
is able to cause hearing loss.
i.
Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring.
Contact with a "live"
wire will also make exposed metal parts of the
tool "live" and shock the operator.
j.
Avoid body contact with grounded surfaces such
as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your
body is grounded.
k.
Explore the workpiece to avoid contact with hidden wiring.
Thoroughly investigate the workpiece
for possible hidden wiring before performing
work. Contact with live wiring will shock the operator.
3 TOOL USE AND CARE
a.
Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against the body is
unstable and is able to lead to loss of control.
b.
Do not force the tool.
Use the correct tool for the
application. The correct tool will do the job better
and safer at the rate for which the tool is designed.
c.
Do not use the tool if the switch does not turn
the tool on or off.
Any tool that cannot be controlled with the switch is dangerous and must be
repaired.
d.
Disconnect the tool from the air source before
making any adjustments, changing accessories,
or storing the tool.
Such preventive safety measures reduce the risk of starting the tool unintentionally.
e.
Store the tool when it is idle out of reach of children and other untrained persons.
A tool is dan-
gerous in the hands of untrained users.
f.
Maintain the tool with care.
Keep a cutting tool
sharp and clean. A properly maintained tool, with
sharp cutting edges reduces the risk of binding
and is easier to control.
g.
Check for misalignment or binding of moving
parts, breakage of parts, and any other condition that affects the tool’s operation.
If damaged,
have the tool serviced before using. Many acci-
7
dents are caused by poorly maintained tools.
There is a risk of bursting if the tool is damaged.
h.
Use only accessories that are identified by the
manufacturer for the specific tool model.
Use of
an accessory not intended for use with the specific tool model, increases the risk of injury to
persons.
4 SERVICE
a.
Tool service must be performed only by qualified repair personnel.
b.
When servicing a tool, use only identical replacement parts. Use only authorized parts.
c.
Use only the lubricants supplied with the tool or
specified by the manufacturer.
5 AIR SOURCE
a.
Never connect to an air source that is capable of
exceeding 200 psi.
Over pressurizing the tool is
able to result in bursting, abnormal operation,
breakage of the tool or serious injury to persons.
Use only clean, dry, regulated compressed air at
the rated pressure or within the rated pressure
range as marked on the tool. Always verify prior
to using the tool that the air source has been adjusted to the rated air pressure or within the rated
air-pressure range.
b.
Never use oxygen, carbon dioxide, combustible
gases or any bottled gas as an air source for the
tool.
Such gases are capable of explosion and se-
rious injury to persons.
Danger from ejected parts
– In the event the workpiece, accessory or machine
parts break parts may be ejected at high speed.
– Wear impact-resistant protective goggles.
– Wear a helmet when doing overhead work. Also
assess the risks for other people.
– Secure the workpiece. Use clamping devices or a
vice to hold the workpiece firmly.

Hazard as a result of dust and vapours
– If hazardous dust is produced during sanding, the
machine should be connected to an appropriate
extractor and the safety regulations that apply to
the working material should be observed.
– A risk assessment in relation to this hazard must
be carried out and corresponding control mechanisms implemented. Arising dust must be factored in.
– Connect the dust extractor. Make sure that avail-
able dust extraction equipment is connected and
used correctly. Observe the regional safety regulations for hazardous dusts and vapours. Operate
and service the compressed air tool as described
in the recommendations included in these instructions and use accessories and attachments
from Festool to minimise the release of dust and
vapours into the atmosphere. In dusty environments, make sure that the dissipation of exhaust
air does not disturb the dust.
– If necessary arising dust or vapours must be con-
trolled at the place of their release.
– All components must be fitted correctly and meet
all requirements to ensure that the compressed
air tool operates correctly.
– Select, maintain and replace accessories and
consumables according to these operating instructions.
– Wear a dust mask. Observe instructions from the
employer or occupational and health regulations.
Noise hazard
– Higher noise level can lead to permanent hearing
damage, loss of hearing or other problems if in-
adequate hearing protection is not worn or available.
– A risk assessment in relation to this hazard must
be carried out and corresponding control mechanisms implemented, e.g. the use of insulating
materials.
– Wear ear protection. Observe instructions from
the employer or occupational and health regulations.
– Operate and maintain compressed air tool ac-
cording to these operating instructions.
– Select, maintain and replace accessories and
consumables according to these operating instructions.

Compressed air preparation
The machine is designed for lubricated operation
and must be operated with the Festool service unit.
Comprising a filter, controller, condensate outlet
and oiler, it ensures clean, oiled compressed air
free of condensation. The oiler must be adjusted so
that approx. every 15 minutes a drop of oil is added
to the compressed air. The correct setting depends
on the daily usage time.
Damage that occurs as a result of incorrect
compressed air processing is excluded from
warranty claims.
We recommend a service unit with a 3/8" connector,
when up to two Festool compressed air tools are
used.
A compressor that supplies at least 350 l/min at an
operating pressure of 6 bar (87 psi) should be used
to supply compressed air.
The diameter of the piping system must be sufficiently large (at least 9 mm (3/8")).
Connection for IAS hose system
The IAS hose system combines several functions in
one hose depending on the version:
– Compressed air supply
– Exhaust air extraction
– Dust extraction
